Femtocells are low-power wireless access points, providing 3G coverage for cell phones and route the calls through the Internet.Ubiquisys, which develops 3G and LTE intelligent cells, says in a blog post that the worlds first attocell "doesnt incur roaming charges because the phone is not roaming, and does not connect to the visiting countrys networks. Instead it travels over the internet to the home country."The company says the device with a range so tiny connects to a users laptop via USB that provides power and an internet connection. The device then analyses the IP address and radio environment to determine which country it is in, and sets its 3G radio power accordingly to below the licenced level. In some countries its range will be just 5 millimeters, in other countries, it could cover a whole room.

In 5mm mode, the traveller simply lays the iPhone on top of the device to enable an automatic connection and calls can be made using a Bluetooth or wired headset , or by using the iPhones speaker.The attocell continuously monitors its radio environment to ensure that there is zero impact on existing mobile networks, says Ubiquisys. This, combined with its tiny power output, is likely to make the attocell exempt from regulatory controls and the requirement for type approval.The device is the first to offer coverage for international travelers, though w! ireless network operators including AT&T, Sprint Nextel, Verizon Wireless and Vodafone have already launched their femtocell services.Formed in 2004, Ubiquisys rolled out the first residential femtocell for less than $100 in December 2009. The company's other investors include tier 1 VCs and T-Mobile. The company counts Nokia Siemens Networks, NEC and Ericsson among its engagement partners."The attocell innovation is a direct response to meet a specific requirement from mobile operators," says Ubiquisys chief executive Chris Gilbert.A study from ABI Research forecasts that by 2011 there will be 102 million users of femtocell products on 32 million access points worldwide.Ubiquisys says it will showcase the attocell at next month's Mobile World Congress in Barcelona.

'Son of star wars' base in Yorkshire finally ready to open

Peace campaigners slam secrecy over $10bn Menwith Hill project that puts UK in line of fire A "star wars" inspired defence shield that will alert the US to the launch of ballistic missiles is expected to be operational from a North Yorkshire airbase before the end of the year. The Space Based Infrared System is seen as the successor to Ronald Reagan's unrealised "star wars" programme, which would have detected Soviet missiles and shot them down using lasers. The new system, which has cost more than $10bn, has taken almost two decades to build and has been subject to numerous delays and cost overruns. The imminent completion of the project at the RAF Menwith Hill base near Harrogate has revived fears that space is in danger of becoming militarised, with Britain in the vanguard. "I find this disturbing to say the least," said a local Labour MP, Fabian Hamilton. "It's as if they are saying this is a place in the US and you are foreigners. But ha...

As China Rolls Ahead, Fear Follows

As China Rolls Ahead, Fear Follows - China kept economy growing in past couple of years by printing money. Now it's feeling consequences. Inflation in consumer prices, speculative bubble in property. Milk dearer in Shanghai than in New York Agence France-Presse — Getty Images China is looking to restructure its economy away from dependence on exports like textiles. For nearly two years, China’s turbocharged economy has raced ahead with the aid of a huge government stimulus program and aggressive lending by state-run banks. But a growing number of economists now worry that China — the world’s fastest growing economy and a pillar of strength during the global financial crisis — could be stalled next year by soaring inflation, mounting government debt and asset bubbles. Two credit ratings agencies, Moody’s and Fitch Ratings , say China is still poised for growth, yet they have also recently warned about hidden risks in its banking system. Fitch even hinted at the ...
