Wi-Fi Multicast

Taiwan's Industrial Technology Research Institute (ITRI) reveals a new streaming technology that solves Internet congestion, especially in dense areas such as stadiums or concerts halls-- and the technology can also be used on high-speed trains.

Similar to broadcasting theory, the Wi-Fi Multicast technology allows 10X more users to use the same amount of bandwidth as provided by typical streaming services.

Wu Cheng-wen, general director of ITRI's Information and Communications Research Laboratories, says their software can change the coding of video data eliminating the need to buy and install new equipment.

ITRI is now talking to potential partners, including cable companies, to transfer the technology for business use. The technology could solve the growing demand for online video sharing and viewing.

Multiple Improvements for Bluetooth

  • PDF

The Bluetooth standard receives a couple of improvements promising more useful devices-- the Bluetooth Special Interest Group (SIG) updates it to version 4.1, and Broadcom combines it with wireless charging on a single SoC.

BluetoothBluetooth 4.1 allows for devices able to "remember" lost connections for longer, with automatic reconnection as soon as devices are in range. It improves on the coexistance of Bluetooth and LTE radios on the device, and adds bulk data transfer capability.

Devices running the updated standard will also be able to run as both peripheral and hub-- the Bluetooth SIG gives the example of a smartwatch acting as a hub by gathering information from a heart rate monitor while simultaneously acting as a peripheral as it pushes notifications to a smartphone.

For the future the Bluetooth SIG plans to add IP connectivity-- allowing devices to communicate over IPv6 via Bluetooth radios to create a "fundamental wireless link" in the so-called Internet of Things.

Infonetics on Home Networking

  • PDF

According to Infonetics Research multiscreen video is an important networking industry driver, pushing global H1 2013 home networking device revenues worth $5.4 billion with 6% Y-o-Y growth.

“Like broadband CPE, home networking devices continue to grow as fixed broadband subscribers increase around the globe," the analyst says. "The types of services being delivered over data networks are growing as well, with the most important being multiscreen video.”

W. European and N. American operators distribute video around the home through higher-end gateways and STBs packing both wired and wireless technology. These in turn drive a secondary market of MoCA STBs and HomePlug adapters connecting TVs, Blu-ray player, game consoles and a growing peripheral ecosystem to home networks.

Wifi? Make Way for Li-fi

  • PDF

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.

micro LED VLCThe 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.
