Microsoft/Yahoo: the return of the rumour of the repurchase

Sources close to Microsoft indicate that the buyout of Yahoo is considered.


Microsoft Yahoo


Microsoft and Yahoo, it has become the story of a great partnership expected to still see the fruits, which recently cost the place of Carol Bartz, CEO of Yahoo dismissed for his lack of results. But before this, strained relations with buyout attempts, it was a little "I love you, me no more". One particularly recalls that in 2008, Microsoft went very far in its intentions of buyout of Yahoo, without that operation results.


And that's that Reuters relaunches the rumor by publishing a dispatch which cites sources very close and in which the Agency says that the possibility of a takeover is currently evaluated at Microsoft. A buyout that would split internally, between those who feel that Microsoft should spend its billions of dollars in a structure showing better growth, and those who see great opportunities of development.


Finally, Reuters said that Microsoft is not the only giant to be interested in a takeover of Yahoo. Indeed, Chinese Alibaba (which Yahoo is a shareholder of 33%) would be interested, like the Russian Digital Sky Technologies Fund. During this time, some relatives of Microsoft disclaim the rumor, explaining that Microsoft does not seek to buy Yahoo, but mainly to obtain assurance of the future stability of the portal, in view of the ongoing partnership with him. Remains that the idea of the sale of Yahoo appears to be its long way...

Android: Ice Cream Sandwich to accelerate the reunification…

If the fragmentation of Android terminals Park tends to tighten on Froyo and Gingerbread versions, Google plans to encourage the gathering around Ice Cream Sandwich.


Android Ice Cream Sandwich


The output of Ice Cream Sandwich would be imminent and looks already capital for Google in its commitment to overcoming the fragmentation of Android, both discredited, especially with developers. But where is it precisely distribution different versions of Android?


Google can be satisfied with Froyo (2.2) fall for the first time under 50% of the Park, to 45.3%, which benefit of Gingerbread (2.3) approaching 40%. Other satisfaction, lightning (2.1) fell to 11.7% of the Android and grinds 1.5 and 1.6 (Cupcake and Donut) apply more only 1.1 and 1.4%. Meanwhile, Honeycomb (3.x) penalty to take advantage of good sales of certain models of Android tablets and represents only about 2% of the Park.


Observers however regretted that the Android Park developments are more to the account of the efforts of builders to generalize the latest versions on their new terminals (including HTC and Samsung that record very large volumes of sales on their recent products, evidenced by the success of the Galaxy S II), on the deployment of updates - involving operators - considered slow and tedious. A situation in which the interest of pushing Ice Cream Sandwich as system Android unified a lot of sense, especially for the Market relies on a compatibility improved applications to boost its revenues...

Nexus Prime wants to exceed the iPhone 4S

Google and Samsung benefit from the disappointment caused by the announcement of the 4 S Apple iPhone to stealthily unveil their future smartphone under Android 4.0.

It is on 11 October that Google and Samsung will throw the veil on what could be a smartphone of exception running the new version of the Google mobile OS namely Android 4.0 Ice Cream Sandwich. Design level already, this smartphone should stand by a form curved involving therefore a curved screen edge to edge occupying the entire width of the mobile.

Slab Super AMOLED of impressive size of 4.7 inches for a resolution of 1280 x 720 pixels HD would then benefit from a near pixel density of the Retina from Apple (against 326 ppp 320 DPI) screens. For the rest, this model would be equipped with a TI OMAP 4460 dual core 1.5 GHz processor, amount of RAM to 1 GB to 16 GB of flash memory. The photo sensor would be a 5-megapixel resolution and would allow the capture of HD video in 1080p. After a Samsung Galaxy S II undeniable and deserved success, Nexus premium therefore Announces under the best auspices.

nexus-prime-samsung-google

During this time, many observers of the market suggests that the relative disappointment General with regard to the announcement of the iPhone 4 S may allow phones Android but also Windows Phone manufacturers to increase their market share. It is, for some, a unique opportunity for Microsoft to finally have its word to say about this market, taking advantage of the arrival of the Nokia under Windows Phone Mango terminals. Others, however, think that Android should take the opportunity to increase its grip on the market even faster.

Should not deny the aura of Apple, and the beneficial effects that could have the iPhone 3GS and iPhone price declines 4 on sales of cabbages smartphones, with subsidized 8 GB models that will become more attractive for the operators.

Sony would like to repurchase the shares of Ericsson

Sony would like to retrieve all of the joint venture founded with Ericsson for its mobile activity.


Sony Ericsson Logo


According to the information reported by the Wall Street Journal, Sony would be about to buy back the 50% of shares that still has Ericsson in the joint-venture they founded together in 2001. The sum that Sony should spend money to retrieve Sony Ericsson in full is estimated between 1 and $ 1.3 billion.


Sony could bring its division telephone branches working from its shelves, its portable consoles or computers yet. In addition to the creative interest and positive excitement that this could create on the R & D, it would be for Sony to reduce costs by developing these synergies.


In loss of $ 50 million in the second quarter with a 1.19 billion turnover, who takes 32% over a year, Sony Ericsson sees its endangered place of sixth manufacturer of mobile in the world. The curve of the smartphone but was rather well taken by the mark, "intelligent" terminals representing approximately 70% of its sales. None of the two parties has wished to react for the moment.

The characteristics of the Thunderbolt according to Intel

Intel took the IDF to give a lecture on the technical characteristics of the Thunderbolt. It has, among other things, formalized the use of the mini DisplayPort. In practical terms, this means that pass through the USB port, as did Sony (cf. "The 1st computer Thunderbolt without Apple"), is not officially the Thunderbolt as it is defined by the official specification, even if it is of identical technologies. We knew that only one type of implementation would survive (cf. "ThunderBolt from Sony, it's optical"). It is Apple who won. Intel says that the first optical cable should arrive next year. They will allow the manufacture of a 10 m cables while we are limited to three metres today. However, they will have 10 Gb/s rates identical to those of copper cables.

The limitations of optical cables flows are due to the Intel will follow the technical requirements specified today. For higher speeds, must await the Thunderbolt 2 which is planned for 2015. This was the message from Intel today who wants to promote a standard clear Thunderbolt to destroy any uncertainty which could hover around its implementation. The Thunderbolt is a mini DisplayPort port able to transit through the video and data using four PCI-Express links. Cables manage two channels and flows are of 10 Gb/s in both directions. The port can provide 10 W of power and it is possible to settle six devices Thunderbolt and a DisplayPort screen. Concretely, this means that to connect multiple monitors on a single port, it will be necessary that they are all compatible Thunderbolt, but the end of the string. The characteristics are identical to what was announced at the beginning of year (cf. "Thunderbolt: 10 gigabits/s, 10 W, Light Peak")

The skier said that the future of Thunderbolt is promising. He worked on the use of Photonic links that would be five times more powerful than today ' hui. But he will have to wait many years land this technology on the public market.

Intel has also shown that it would be the guardian of the Thunderbolt, relieving Apple of this responsibility. The purpose is to reassure the PC manufacturers who may fear to be at the mercy of their competitor. If Apple has started the procedure to protect the brand Thunderbolt, the rights will be transferred to Intel who has already created a community around this technology. He also has opportunity to give a list of manufacturers who have already adopted this format. There is the presence of Canon, which confirms rumors that we reported you last March. The absence of Dell, Lenovo, HP, or Samsung is still very notable and despite the enthusiasm of Intel can help discern a reluctance on the part of manufacturers who prefer to wait to take the step of the Thunderbolt.

AirPort 2011: Apple multiplies the power of the Wi - Fi

At a time where waves (in General) are controversial, as shown in our folder, Apple "innovates": the new generation of AirPort Extreme enclosures increases the power transmit in Wi - Fi. Indeed, Apple recently modified posts, and if the specifications appear identical, there is a big difference to the level of power.

The FCC, which validates the products to be marketed in the US, indicates that in 2.4 GHz - the band frequency used in 802.11 b, 802. 11 g and 802 .11n-ready power passes 130 MW (in 11n) to 260 mW. In 11 g, is 143 to 307 mW and 286 to 257 (decreased) 11 (b). When working in the band 5 GHz for higher throughput, going from 139 to 392 mW (.11n ready/40 MHz), 164 to 337 mW (.11n ready/20 MHz) and 202 to 322 mW when it uses the very confidential (in Europe) 11.

As seen, the power increases many and the scope should therefore follow the same path. Remember everything and in France, ARCEP limit to 100 mW in 2.4 Ghz and 200 mW transmit or power 1 W at 5 GHz, based on the selected channel. Terminals, which allow to choose the country in which they will be used, a priori limit power via the firmware to stay within legal limits, but it is of course quite simple to further... In the meantime, electromagnetic radiation-sensitive individuals should avoid this type of Terminal...

The AdS: a drone for hack Wi - Fi networks

This week in the AdS, hackers fly. You surely know the AR .drone Parrot, a French company. This Wi - Fi led quadricoptère via a smartphone sensation and a lot of success. And American researchers said that an aircraft flying, not too large, could be interesting for... pirate of Wi - Fi networks.

They therefore installed a computer under Linux - a map of ARM processor-based development-, a Wi - Fi card, a GPS receiver and especially a 3 G connection: although it is possible to break the WEP key quickly enough, this is in part dependent on the processor, very slow here. And so are the Amazon cloud servers which are used to break the encryption keys, they are in WEP or WPA.

For the anecdote, they called the prototype SkyNET and has a (small) problem, its autonomy. Indeed the AR.Drone does not exceed 15 to 20 minutes in flight with a battery, which is a little light.

CPL 500 Mbps and gigabit switch... at the same time

The CPL has the wind and the France is a country where the technology is very present (builders can thank the FAI). And if Free, SFR or Orange use enclosures "200 Mbps", there are now templates "500 megabits/s". In both cases, theoretical values and must be at least divide the values by three for the practical flow rates, but it is usually more than enough for domestic use.

The new model of Trendnet, TPL-405, is an adapter 500 megabits/s which has a special feature: it incorporates an Ethernet switch with four connectors. If the connectors themselves may work to 1 gigabit/S, the CPL limit network, but the whole quite practical: simply a box to connect the console, the TV, Blu - ray drive, etc. Good news for many: the Ethernet remains majority on salon equipment and optional Wi - Fi adapters are expensive.

TPL-405 is complete and even if its price is higher than the average (€70), it allows to save the price of an Ethernet switch. The enclosure should be available in December.

This is the day of the Wi - Fi: 8.02.11

Today, we are on August 2, 2011. Is, in American notation, the 08.02.11. And many have recognized the Wi - Fi, IEEE 802.11 standard code name.

Wi - Fi is a very common technology for a decade, especially since Intel is spearheading its Centrino technology in 2003. The first trials of the technology in the public date from 1999: Apple launched its AirPort technology (trade name Wi - Fi did not yet exist) with the iBook. The company used equipment to the 802 .11b standard, abandoned since. Remember that the name Wi - Fi is commercial and that the standard well officially named the IEEE802.11.

The first version of the standard is the 802.11: validated in 1997, it allowed to reach 2 Mbps in the 2.4 GHz frequency band. Little used, is found again from time to time industrial.

The version "a" of the standard has been little used in Europe, but is common in the United States. It allows to reach 54 Mbps in the 5 GHz band. It has the defect does not well cross walls, unlike the "b" of the standard version. The majority of current chips are compatible with standard 802.11 a, even though it is rarely used.

The "b" version was used in the first half of the 2000s. Able to reach 11 Mbps, it works in the 2.4 GHz band and its scope is correct. It is the standard used in the first Wi - Fi devices and the mobile first Centrino.

The "g" of the standard version is still the most used currently. It reached 54 Mbps as the 802 le 802 11 11, but has the advantage to remain compatible with 802.11 b devices. The second version of the Centrino chipset was taking support this technology. It is very used, because its bandwidth is sufficient for a classic Internet connection and production costs are very low.

The most used standard in 2011. Flows vary depending on the number of antennas and the chip, but devices are often found at 150 Mbps (entry), 300 Mbps (the classic) and 450 Mbps (high end). The standard may work in 2.4 GHz for a backwards-compatible 802. 11 b/g or 5 GHz to increase flows. some chips can use two frequencies simultaneously.

802 There is a variant of the 802.11 a 3.7 GHz band. It is primarily used in the United States for its very high reach outside, to connect buildings between them, for example.

The "ac" version is the next standard to be used in the general public. Still in draft State, it will achieve very high flow rates: 433 basis, 867 Mbps or 1 734 Mbps in advanced equipment and the best 6.93 gigabits/s in the fastest machines (with 8 antennas). This standard should be finalized during the year 2012.

There are limits to AirDrop, Wi - Fi Direct from Apple

Apple, in Mac OS X Lion, provides a new tool for file sharing, AirDrop. The idea is attractive: this system integrated into the Finder allows to share files quickly between two users. The operation is simple: clicking on AirDrop, the list of people nearby appears and simply drag a file so that it is transmitted. A "pop-up" appears on the host machine to accept the file, and the transfer occurs.

Under this simple appearance, AirDrop is technically quite interesting: it is a direct link is created between two computers that share data. Binding is done in Wi - Fi 802 .11n ready in the 5 GHz band for high flow rates (450 Mbps on recent machines) and data are therefore not through conventional network, the binding is dedicated. Operation is close to that proposed the Wi - Fi Direct or Bluetooth 3.0 standard, but Apple here uses Hello and the possible cache operation internal technology.

The main problem is that to work, AirDrop a Wi - Fi card needs - some Apple machines are not equipped with - compatible 802 .11n ready and able to work in "dual band". This last point is the most embarrassing: all cards are not able to work on two bands simultaneously. Specifically, Apple uses three cards 802 .11n ready in his cards: from Atheros, Broadcom of type 432 x and of type Broadcom 943 x. And only the latter are compatible.

Hackintosh lovers, it will therefore be difficult to take in charge AirDrop: the majority of the maps of the market are of Broadcom 432 x. And for users of machines Apple, only output machines since end of 2008 (and again, not all) will be compatible.

NETGEAR repeats the Wi - Fi .11n ready

NETGEAR offers a device that will appeal to people who have large spaces to cover in Wi - Fi: a Repeater able to work in Wi - Fi 802 .11n ready. The WN3000RP is a fairly compact Terminal able to extend a simple Wi - Fi in a secure manner and - Netgear - network.

The device connects to a power outlet and extends your network Wi - Fi in a transparent manner, with more opportunity to connect an Ethernet device on the device, which can serve as the bridge. For people on the WPS (Wi - Fi Protected Setup), the operation is childish: just press the button for the security of the network. For others, it is quite simple: it is sufficient to indicate to the WN3000RP network to expand and the WPA key.

Point of the device, it is compatible with the 802 .11n ready standard, which allows to extend the network while keeping correct performance, while many of its competitors are compatible with the 11 g standard. Attention, only the 2.4 GHz frequency band (most common) is supported.

The price announced for this aircraft is €70, the price of a typical access point.

A Samsung monitor supplied with Ethernet

Samsung has announced the NC220, a screen that has the particularity to feed in Ethernet. There is currently very little details on this screen, a priori a diagonal 22 inches (in view of its name), and the only thing on which the Korean firm communicates is its food.

In fact, it uses the standard UPOE, worn by Cisco: the Universal Power Over Ethernet is an enhancement of the PoE classic and allows to provide 60 W to a device, against 30 W usually. With this power, it therefore is more confined to cameras, phones and other Wi - Fi access points and it is possible to feed screens backlit by LED (as this model).

The press release gives little information, but the NC220 is obviously a thin client: USB ports allow to connect a keyboard and a mouse on the screen, and the latter then serves light terminal: the operating system and data are supported by a remote server. This is a trend that existed for many years in it, but current systems finally make viable whole. Cloud computing, an end to the mode currently, is that a new term for something that existed for many years...

Remains to be seen what is needed at the level of the servers for this screen, knowing that an architecture using Cisco equipment is required for the power of the screen.

Farewell WiFi: a network led reached 800 Mb/s

October 2008, researchers from the Boston University's College of Engineering evoke the idea of a network of wireless communication using radio waves as WiFi or 3 G but simply light - a luminous walrus of the 21st century in a way not not. Their prototypes peak at 10 Mbps. 2011: the idea made its way and was taken over by the OMEGA European research program. The flows reach almost 1 Gb/s in the laboratory.

The principle of this network is very simple: the data are transmitted in the form of the flashing light-emitting diodes (LED) very high frequency. As on optical fiber, multiplying flows by adding several wavelengths through red, green, blue and white LEDs. In the end, this network has many advantages:

extremely simple installation in a House: just replace the bulbs by LEDinsensibilité interference électromagnétiquesaucune electromagnetic pollution, a point important to electro, aircraft or equipment médicauxfaible énergieun consumption only transmitter can serve several customers, without the necessary bandwidth multiplication (broadcastsécurité since the communication is possible in the cone of illumination of the transmitter)

Of course, also can find many drawbacks, the most obvious being the need to maintain direct visibility of the receptor by the issuer and to maintain the lit lamp. These two conditions are met however in many environments such as offices in open space, restaurants, etc.

Researchers at the Fraunhofer Heinrich Hertz Institute (HHI) manage to maintain a flow of 125 Mb/s with components at low cost and simple encoding on / off. With LEDs most efficient avalanche and a WDM modulation, they reach 800 Mb/s. This network will be showcased at the next IFA in Berlin in September.

Cisco will help China to monitor its citizens

Cisco will be one of the major partners of the Chinese Government in the creation of a video surveillance system consisting of 500,000 cameras located in the city of Chongqing. The official program named tranquil Chongqing purpose is to combat crime, but the associations for the protection of human rights argue that it is a way more easily follow and stop political dissidents, according to the Wall Street Journal estimated that it could be one of the largest surveillance video systems of the world.

The city of Chongqing has an area of over 82,000 km2. For comparison, this is two times larger than the Aquitaine region. According to the daily, Cisco should provide, in this project, the network equipment needed to operate a system of broad monitoring and complex. U.S. law prohibits export to China of some tools that could be used for repressive purposes. It is for example the case of fingerprint readers. Nevertheless, the associations are up in arms for the lack of relevance of the Act does not prohibit the export of cameras or software censuring Internet.

Cisco refuses to comment and says only that it did not sell cameras or video monitoring solutions. This case tarnishes nevertheless a little more his picture while he was charged last may provide equipment used by the Chinese Government to capture members of the religious movement Falun Gong (cf. "Cisco accused of helping China to block Internet"). It would not however the only American to participate in the operation. HP could sell servers and storage solutions.

The project should cost 2.2 billion (CA. 1.5 billion euros). Only $ 800 million would come from the Government (CA. 500 million euros). The 1.6 billion (EUR 1 billion) still would be from sources that have not been disclosed.

The end of the Minitel in 2011? No, in 2012

We saw a few days ago an alarming report on a large chain of television: the network Transpac of France Telecom is announced as to close in September 2011, without a real solution to replace. As Transpac is used for the Minitel, still used, this new course raised an "outcry". Yet... it is false.

In fact, Transpac will be closed in June 2012 and not in September 2011. Closure in 2011 has in fact been announced via a press release in January 2010 but it was postponed to June 2012 a little later, without the France Telecom communicates too much. Conditions of uses of Télétel - used for the Minitel network - are quite clear on this point: the version of May 2011 indicates a final closure on 30 June 2012 then the opening of new services will be available until February 29, 2012. Persons still dependent of the Minitel and the X.25 more generally have about a year to find a replacement solution.

Transpac is the name of the X.25 of France Telecom network, the largest of the world, and it is still active. It uses technology, X.25, a communication protocol that works by package. X.25 has been standardized in 1976 and has been used in France to essentially two things: the Minitel, the network Télétel, and some banking exchanges with ETEBAC (Exchange telematics bank customers). The judgment of the Transpac network will therefore involve the closure of the network Télétel, used as the basis for communications on the Minitel, and ETEBAC. For the latter is not a real problem, systems based on a connection to the Internet as simple and as complete (see), for the Minitel, if more embarrassing. Indeed, some services do exist on the Minitel or offer more options on the latter.

In June 2012, after the SECAM, this will be another "glory" of the French technology that will disappear. Remains to be seen if France Telecom will really close Transpac in 2012: it is quite possible that an extension of the lifetime of the service (launched 1978) to be announced in the future.

The discreet and rapid CPL in Netgear

In the small world of the CPL, two types of packages has for long been: the classics without female and those with a Jack. The seconds, more expensive, are generally more successful: they better filter disturbance and it is possible to place them between a multiprise and the wall, which prevents parasites due to devices such as smartphones Chargers or halogen lamps.

Since a few months, we see also the "nano" adapters, smaller all while remaining efficient. And there is therefore now "nano" to a female connector adapters. After the French home Lea, is Netgear that QuickDraw: XAV1601 housings are compact and offer a Jack. It is conventional technology, the HomePlug AV 200 megabits/s in theory, and it is of course secure via encryption in AES 128-bit. As usual, don't expect to really 200 megabits/s: Netgear speaks of 90 Mbps "application flow" (a euphemism to refer to real flow) and our tests have shown that it is difficult to exceed 70 Mbps in TCP, even on an electrical circuit dedicated.

The boxes are sold in kit for €90 and it is possible to buy a single package at a price of €50. Note that the society should also propose a variant with two Ethernet jacks under the name of XAV2602.

G.hn in Marvell chip: the utopia of universality

Marvell today puts on the market its first chips with the G.hn standard. If you have never heard, be aware that this new standard aims to provide an "all terrain" communication protocol which purport to live as a coaxial cable than a simple telephone cable or the power grid. Maximum flow at 1 Gbit/s.

For the user, the G.hn has little interest: it is almost as well today with the Ethernet and CPL. But for hardware designers, the potential is: a single standard and a single chip would be sufficient to make it compatible with any installation equipment. This beautiful promise however happen that if a large group of manufacturers are adopting the G.hn. However, the home is rather mixed.

The G.hn is also shot himself in the foot by not solving the problems of adverse between three standards of equipment existing CPL (standard HomePlug, UPA PLC and HD - PLC). Marvell, for example, which has bought German DS2, ensures interoperability of its chips G.hn with CPL equipment based on DS2 (UPA PLC) technology. Unfortunately most of the CPL adapters marketed today are standard HomePlug, inconsistent.

Another supplier could take advantage of the game this: Sigma Designs. Repurchasing Connexant, one of the promoters of the HomePlug standard, the company is able to design chipsets G.Hn compatible HomePlug.

Nostalgeek 2001 (18) : Via, Wi-Fi, Plextor

This summer, we will offer you the return of a topic, Nostalgeek. And we decided to dwell on a specific year: 2001. Distant and close both, the year 2001 is interesting to analyze, to show developments in the high-tech in 10 years. Each day, during the holidays, we will offer you a retrospective of a week of 2001, with the news of the day and a small analysis on what there is in 2011.


And we are in May 2001.



Via chipsets specialist, is well and poster sales on the rise, in 99 million of $ on April. Intel, meanwhile, decreased the price of its processors: the recent Pentium 4 1.7 GHz is worth $352 (and this is the top of range) and other models are worth between 193 and $256.


In 2011, Via has a turnover of 15.7 million from $ in April. At Intel, processors for individuals reach $1,000 and a few high-end models exceed $500. The price of ix (excluding extreme and Pentium) Core ranges from $113 to 583.


In the GPU, the rumours about the next entry-level NVIDIA circulate. The NV17 would therefore be a "GeForce 3 MX".


In 2011, it is known that the NV17 was a variant of the GeForce 2, exit as the GeForce 4 MX and GeForce 3 chip was never declined in a low version of range.


In storage, the first 24 x writers arrive (3.6 MB/s) and Plextor will offer IDE, SCSI and FireWire versions. In networks, the first products Wi - Fi at a correct price arrive: card 802.11 b (11 Mbps) about €250 and access points including an Ethernet, a modem V.90 and the WEP. The 64-bit WEP, to pay about €500 and for the 128-bit WEP, the price rises to 1 €350. Remember that Apple provides its products AirPort (trade name) for $100 card and $300 the kiosk (Ethernet/V.90/WEP 64-bit).


In 2011, the engravers are SATA and possibly USB (2.0 or 3.0) but the IDE, the SCSI and the FireWire are very rare. In Wi - Fi, cards work to 450 megabits/s and are integrated into the computers and access points incorporate Ethernet 1 gigabit/s. In the majority of cases, the access point is available with subscriptions to the Internet.

900 Mbps Wi - Fi (or the joys of marketing)

NETGEAR has announced a new access point Wi - Fi, capable of reaching 900 Mbps by brand. The society plays a little on the words in announcing this speed: the WNDR4500 can actually achieve 450 Mbps in the 2.4 GHz band and 450 Mbps in the 5 GHz band. In fact, even if the access point issues in the two bands simultaneously, devices such as portable computers confined to a single band. In addition, must be able to work to 450 Mbps, Wi - Fi card only last generation Broadcom chips and 5300/6300 family Centrino chips can help.

However, the device is fairly complete: compatible WPS (for the management of security), it is also able to work in IPv6. Wi - Fi, it is compatible 802.11 b, g and .11n ready in 2.4 GHz and 11 and .11n ready in 5 GHz. It is therefore able to work on two frequencies at the same time, with both Wi - Fi cards, and it can also create a core network and a second dedicated to the guests. The wired part, is found four catches RJ45 1 gigabit/s and a WAN decision-making to the same standard. The access point offers also two USB 2.0 ports, to share key USB, hard drives, or printers.

Outside the gimmick marketing at the level of the actual speed, there is the failure of the price: $ 180, it is rather expensive for a "public" access point, especially when operators offer the Wi - Fi in the majority of the FAIbox, even if they are not as efficient as a model dedicated such as NETGEAR. Note that with the logic of addition of the two bands, the company could also indicate that the network portion can reach 4 gigabits/s...

A WiMAX router for mobility

For the few people who have access to the Internet in WiMAX, I - O DATA offers an interesting solution with WMX-GWMR. Indeed, this small device is a WiMAX router able to redistribute the signal Wi - Fi standard 802. 11 g. It's interesting for people who are smart phones, tablets, or simply of the Notebooks are not compatible WiMAX: the apparatus will be the bridge between the WiMAX and Wi - Fi, as 3 G routers that become more and more popular.

The compact router 96 x 68 x 17 mm for 99 grams and can reach 40 Mbps in WiAMX in the 2.5 GHz band. He worked in 802.11 g Wi - Fi (54 Mbps) and comes with a dock. Its internal battery offers to 6 hours approximately and part Wi - Fi supports the WPA2.

For the price, it remains high: 21,000 yen, roughly €170, but mobility at a cost...

Free remove an update of the Freebox

Yesterday, Free proposed firmware 1.1 of the Freebox V6 and today, this firmware has been disabled. Indeed, many people returned to version 1.0.5.1 and the new firmware is no longer available.

Without that it is official, two reasons are emerging. the first is a bug blocking: our brothers have reported that many users had problems with the phone by installing the new firmware. Free have therefore decided to return to the old firmware the time to correct the bug. The second reason would be bound to a function: Free has proposed a new function called "AirMedia" in the Freebox. And AirMedia is "compatible" AirPlay, Apple technology. Seen the price charged by Apple for the implementation of AirPlay (informally between 40 and $100), Free surely uses ShairPort, an implementation open source of AirPlay, which uses the key private to an AirPort Express Terminal. That Apple has applied for Free to remove this function violates the intellectual property of the firm is therefore not excluded...

In the meantime, bridge, awaited by some, how does will be therefore remained available that shortly...
