Qualcomm Bets on WiGig With Wilocity Buy

Qualcomm moves forward in WiGig 60GHz wireless technology (aka 802.11ad wifi) adoption with the acquisition of pioneer Wilocity and the announcement of a mobile SoC reference design featuring the technology.

"WiGig will play an important role in Qualcomm's strategy to address consumers' increasingly sophisticated smartphone, tablet and computing requirements," the company says. It does not reveal how much it paid for Wilocity, but its pricetag was reportedly set at around $300 million.

Wilocity is one of the founding members of the 802.11ad working group, and already sells WiGig solutions to Dell and Cisco.

Cisco: Wifi Traffic To Exceed Wired by 2018

Cisco: Wifi Traffic To Exceed Wired by 2018

According to the Cisco Visual Networking Index report wifi traffic is to exceed wired traffic by 2018 as global IP traffic across fixed and mobile connections grows nearly 3-fold over the 2013-2018 forecast period.

Spurring such growth are growing internet user and device numbers, faster broadband speeds and increased video viewing-- for instance Cisco predicts the FIFA World Cup alone will generate 4.3 exabytes of IP traffic, 3 times the monthly IP traffic generated by host city Brazil.

Following that Cisco expects global IP traffic to reach 132 exabytes per month by 2018, the equivalent of 8.8 billion simultaneous 4K/UHD World Cup final streams.

Non-PC devices are a main IP traffic driver-- 33% of 2013 IP traffic came from non-PC devices, a share forecast to grow to 57% by 2018 through TVs, tablets, smartphones and M2M connections.

A Device For SIM-Based Wireless Authentication

A Device For SIM-Based Wireless Authentication

Japanese carrier Docomo announces what it claims is the first SIM-based authentication device-- Portable SIM, a standalone device combining a SIM card with Bluetooth and NFC in a potential SIM card replacement.

According to the company Portable SIM will allow users to connect and login to phone networks and transfer information (such as contact and login details) across multiple devices with a simple wave.

Bluetooth connectivity replaces the need to physically insert a SIM card, and Docomo suggests users would even be able to switch subscriber identity between personal and work devices as Portable SIM can securely store multiple login details.

Adding further technology is the fact transferred contacts and details lock if the Bluetooth connection is lost.

Google’s Satellite Plan for the Internet

Google’s Satellite Plan for the Internet

Google plans to spend more than $1 Billion on a fleet of satellites to bring internet access to unwired parts of the globe, according to the Wall Street Journal. The project will use small, high-capacity low-Earth orbit satellites that sit closer to the ground than traditional geostationary satellites, reducing lag times.

Internet services by satellite are widely available today from operators such as Astra and Eutelsat, operating in geostationary orbits at approximately 36,000 km altitude. At a rather lower level, the Iridium satellite network offers a global network from about 800km height, and is widely used for satellite phones and maritime services. Google is reported to be looking at orbits of only 160 km high, with the potential to remove any notable lag for the connection.

This project can be seen from several angles. At one level it is an altruistic effort to connect the digitally disenfranchised peoples of the globe, while other might describe it as a bid for first-mover advantage for the next wave of internet growth.

Wifi Gets NFC Connectivity

Wifi Gets NFC Connectivity

The Wifi Alliance plans to add Near Field Communication (NFC) to its Certified Protected Setup program, making connection setup as easy as tapping 2 devices together.

Such "tap-to-connect" capability will allow the connection of devices to the internet or networks by simply tapping a router. Users can set both traditional networks with an access point and Wifi Direct groups.

The first devices supporting the NFC option include the Broadcom Dual-Band 802.11ac access point, the Marvell Avastar 88W8787, the Mediatek NFConnected AP and NFConnected STA, the Qualcomm Dual-Band XSPAN 2-stream 802.11n WLAN adapter and the Nexus 10 tablet.

Wifi? Make Way for Li-fi

Wifi? Make Way for Li-fi

UK-based researchers at the Ultra-Parallel Visible Light Communications (UP-VLC) project announce a breakthrough in visible light communications (VLC), reaching data transfer speeds of 10Gbps with a system using tiny micro-LEDs.

The researchers hail from the universities of Edinburgh, St Andrews, Strathclyde, Oxford and Cambridge.

Reportedly the system transmits 3.5Gbps through each of the 3 primary colours (red, green, blue) making up white light, this increasing the amount of data the light can "carry." This makes the the basis of what the researchers call light fidelity or "li-fi," a potential low-cost alternative to radio-based wireless internet.

"If you think of a shower head separating water out into parallel streams, that's how we can make light behave," Prof Harald Haas tells the BBC.

Allowing the micro-LEDs to handle millions of light intensity changes per second is Orthogonal Frequency Divisional Multiplexing (OFDM), a dgital modulation technique making what amounts to an extremely fast on/off switch.

Wireless Network Reaches 100Gbps Record

Researchers at the Fraunhofer Institute for Applied Solid State Physics (IAF) and the Karlsruhe Instute of Technology (KIT) manage a world first-- wireless data transmission at 100Gbps.

The wifi tests use 237.5GHz signals over a distance of 20m in laboratory conditions. However the super-high frequencies involved demand clear line of sight between devices at all times.

“At a data rate of 100Gbps, it would be possible to transmit the contents of a Blu-ray disk or of 5 DVDs between 2 devices by radio within 2 seconds only,” researcher Prof. Ingmar Kallfass says.

IEEE Kicks Off High Efficiency WLAN Group

IEEE creates the IEEE 802.11 High Efficiency WLAN (HEW) study group, with the aim to enhance the efficiency and performance of current WLAN deployments-- creating a new wifi standard in the process.

The study group will consider use cases including dense network environments with large numbers of access points and stations.

Expressing interest in the future HEW project are over 300 individuals from equipment and silicon vendors, service providers, carriers, systems integrators, consultant organisations Continue reading...
