The first chips Qualcomm Atheros arrive

The buyback Atheros Qualcomm is beginning to show fruit. Qualcomm Atheros is a subsidiary of Qualcomm, which has therefore to announce his "first" chips. The first, WCN3660, is a chip designed to assist the SoC Snapdragon, pending integration into the future. The chip supports 802.11n Wi-Fi on a channel (150 Mbps) in both conventional frequency bands, the 2.4 GHz and 5 GHz.

Compatible with Bluetooth 3.0 and 4.0, it is also capable of receiving analog radio signals and is even compatible RDS. The chip is expected in late 2011 and will be compatible with most operating systems. The second, AR9004TB is a smart Wi-Fi WiGig but also an evolution of the standard.

Get Wi-Fi N Dual Band USB port on his

Trendnet has just introduced what it considers to be the first USB Wi-Fi N Dual Band, but one can question the usefulness of the TEW-684UB. The firm says it is possible to connect the adapter to the wireless router to take advantage of the Internet, and the second antenna is used to connect to another USB Adapter Trendnet Wireless N.

This suggests that this adapter dual band plays primarily the role of tutor. The TEW-684UB is a complement to the TEW-687G, an adapter that acts as a repeater, that is to say, he picks up the network router to return it to another terminal. The TEW-687G uses a Gigabit Ethernet port. The TEW-684UB uses the same principle, but the Internet connection sharing wireless router with other Wi-Fi instead of an Ethernet connection.

A Wi-Fi 11n ... for public places

Ruckus Wireless offers a new 802.11n Wi-Fi hotspot "professional", which improves - according to the company - the range and throughput. The ZoneFlex 7341 is compatible 802.11n, but is limited to the 2.4 GHz band (some working in 5 GHz) and can be powered via Ethernet. The terminal can be hung on the wall, supports QoS to limit certain uses and may create eight different SSID, which is interesting in some places.

A router for WiMAX mobility

For the few who have Internet access in WiMAX, IO DATA offers an interesting solution with WMX-GWMR. Indeed, this little device is a router capable of redistributing the WiMAX signal using Wi-Fi, 802.11g. It's interesting for people who have smartphones, tablets or laptops simply are not compatible WiMAX: The device will bridge the gap between WiMAX and Wi-Fi, like the 3G routers become increasingly popular.

An 8 GB SD card with WiFi

Eye-Fi has unveiled a new model equipped with an SD card controller integrated WiFi. Called X2 Mobile, the model in question shows a storage capacity of 8 GB and is designed for digital cameras. The manufacturer says that through technology "Direct Mode" built into this card, you can connect the camera to a smartphone or a touch pad running Android or iOS (via a dedicated application), the then acting as X2 Mobile WiFi access point.

SFR of PLC for Neufbox Evolution

At the launch of the Evolution Neufbox SFR proposed CPL - like its competitors - but it was classic designs from trade. We had been discussing it with company officials and they indicated that we had worked on SFR integrated models in the diet of the case, but the aspect of "consumption" was still posing problems.

This is clearly resolved, with the outlet boxes CPRA. Like Free, SFR has integrated PLC controller in the diet of its case. Compatible with Neufbox Evolution and TV decoder, CPRA replaces the original supply. For the rest is classic: the CPL announced to 200 megabits per second but in practice limited to 100 megabits / sec CPRA is quite simple - it is completely black - and appears to compact.

Finally blocks compact PLC

Netgear has announced a new generation of PLC blocks and - good news - they are finally compact. The new range of "Nano" (AV 200 Powerline Nano XAVB2101) is considerably smaller than older models and functions are the same: a connection to 200 Mbps in theory and about 70 Mbps in practice. To get an idea, Nano measuring 67 x 55 x 34 mm, conventional models are 90 x 53 x 32 mm (they are much longer) and models with a female are 138 x 65 x 40 mm.

Domino wins the Orange screen

The 'Domino' Orange wins a screen. This small device can actually do what the majority of smartphones offering lately: sharing a 3G wireless connection Proposed for two years at Orange, the original is a Domino Huawei E5830 while the new model is a Huawei 585. Operation is simple: the Domino accepts a SIM card and can then share the connection with Wi-Fi 802.11g to 5 devices.

It is 3G compatible (up to 7.2 megabits per second) but also EDGE and GPRS. Good idea, the unit accepts microSD cards and can therefore serve as storage media. In addition to Wi-Fi, the device can also connect via USB, so classic, and serve as a key 3G. Autonomy announced is 5 hours and - new - a screen to check the type of connection used, the number of customers and especially the volume of data exchanged.

A radio and free Wi-Fi router hacking DIY

Want to get a Wi-Fi radio at low prices and free at that? It's possible, thanks to OpenWRT. This Linux distribution is scheduled to replace the firmware on some access points Wi-Fi based on Broadcom chip and has a lot of functions. One is the ability to play streaming radio broadcast on the Internet.

Using a wireless router with a USB port, such as Asus WL-520GU, it is possible to connect a USB sound card and turn the access point (worth about 60 €) Wi-radio Fi. In fact, the USB sound cards generally use generic drivers so will work directly with most operating systems, including OpenWRT.

A Wi-Fi adapter N is to be forgotten

D-Link has just introduced its first Wi-Fi adapter N (150 Mbps) at Pico USB DWA-121. Reserved for the moment in North American market with a European release date still unclear, this adapter has the great advantage of offering Wi-Fi n old computers with no such module. It is much more convenient than the opening of its case for inserting a PCI or PCI-Express and much more aesthetic than larger dongles protruding antennas that are marketed today.

40 Gb / s with a laser and fiber

Fujitsu has just announced an interesting technology: they were able to bind to 40 Gbit / s using a directly modulated laser and without cooling. It's interesting in the sense that conventional systems that achieve this speed generally require external optical modulation system, which must be cooled and therefore increases the cost.

Usually, direct modulation can not exceed 10 gigabits per second Fujitsu's technology achieves 40 Gbit / s optical fiber with a range of 5 km without repeater and especially without active cooling, the system operates between 25 ° C and 70 ° C. The cost is lower than conventional technologies and Fujitsu is working with a wavelength of about 1.3 micrometers.

An iPhone for network administrators

For network administrators who want to work in mobility, there is now a solution for some cases: the cable Redpark. It actually allows you to connect a device iOS (iPhone, iPod touch, iPad) to a Cisco device via a dock connector. The cable - sold $ 69 - offers connectivity "dock" on one side and an RJ45 on the other.

It does not connect to ports "console" of Cisco equipment to do maintenance on the aircraft of the mark, it is not an Ethernet connector. In addition to cable, an application iOS is necessary, "Get console. The latter, sold € 8, lets you connect devices to the mark-mode terminal and perform maintenance on the devices.

1 billion WiFi chips in 2011

Analyst firm iSuppli Research has addressed the growing importance of market solutions for different WLAN chip manufacturers. Thus, according to iSuppli forecasts, nearly a billion WiFi chips should be delivered this year. Growth should then not falter because the firm expects that the threshold of two billion chips shipped annually by 2014 should be exceeded.

This growth is explained by the inclusion of such chips in a growing number of devices: game consoles, televisions, digital cameras, touch pads and of course smartphones. The arrival of new standards, faster, should finally allow at least partial renewal of the existing park, which will energize even the growth of this market ...
