New ITU standard opens doors for unified 'smart home' network
ITU has approved a new technical standard that will usher in new era in 'smart home' networking systems and applications. Called 'G.hn', the new standard will enable service providers to deploy new offerings, including High Definition TV (HDTV) and digital Internet Protocol TV (IPTV), more cost effectively. It will also allow consumer electronics manufacturers to seamlessly network all types of home entertainment, home automation and home security products. more

Radio waves 'see' through walls
University of Utah engineers showed that a wireless network of radio transmitters can track people moving behind solid walls. The system could help police, firefighters and others nab intruders, and rescue hostages, fire victims and elderly people who fall in their homes. It also might help retail marketing and border control. more

Standards Body Approves Wi-Fi Standard Supporting 300Mbps Download Speeds
The standards body, the ieee has ratified the ieee 802.11n-2009 amendment, defining mechanisms that provide significantly improved data rates and ranges for Wi-Fi networks (WLANs). The 560-page 802.11n amendment will enable rollout of significantly more scalable WLANs that deliver 10-fold-greater data rates than previously defined while ensuring co-existence with legacy systems and security implementations. more

Future of WiMAX uncertain, as Clearwire investors write off billions of dollars
Comment by Terry Norman, Senior Analyst at Anlaysys Mason
"Over the last two or three years, WiMAX has gained a strong foothold in
developing countries in which there is a need for broadband, but the fixed
infrastructure is poor. However, Analysys Mason doubts that the developing
market offers sufficient growth potential and size to sustain continued
investment from such heavyweights as Cisco Systems, Intel and Motorola without
additional sales in the developed markets. But in the developed markets of
Europe and the USA, we see some early signs of a difficult future for WiMAX.

Memory with a twist: NIST develops a flexible memristor
Electronic memory chips may soon gain the ability to bend and twist as a result of work by engineers at the National Institute of Standards and Technology (NIST). As reported in the July 2009 issue of ieee Electron Device Letters, the engineers have found a way to build a flexible memory component out of inexpensive, readily available materials. more

Over Half of Cellular Backhaul Capacity will be Ethernet by the End of 2011
While microwave will remain the most common last mile link medium, Ethernet is playing an increasing role in supporting backhaul needs for cellular and WiMAX networks. Over half of cellular backhaul capacity will use Ethernet by the end of 2011, reports In-Stat. The transition to Ethernet will vary by region, depending on where mobile operators are in their transition to 3G and LTE networks. more
