Hewlett-Packard said on Monday it plans to buy Colubris Networks, furthering the consolidation of wireless networking companies. Financial terms were not disclosed. HP said the deal should close by the end of fiscal 2008, which occurs in October. Colubris, founded in 2000 and based in Waltham, Massachusetts, sells wireless access infrastructure products based around the 802.11n wireless standard, which can match or best the speeds of a plugged-in broadband connection. But the upgrade to 802.11n poses many issues for it to work efficiently. Colubris has centered many of its products around the predicted upgrade of those networks over the next few years. Colubris also sells wireless security and network management products. HP said products from Colubris will be incorporated into its ProCurve Networking portfolio, which will improve HP's ability to serve the health-care, transportation, manufacturing and education markets, among others. In June, Belden said it would buy WLAN vendor Trapeze Networks for US$133 million

"Wireless charging manufacturers are expected to reach economies of scale to offer the technology at a competitive price by 2016 or 2017. The perceived value also may improve with time. The smartphone market is the earliest adopter of wireless power charging technology, and is the largest revenue contributor to the global market. Other potential applications include consumer electronics (e.g., tools, lights, phones, headsets, and laptops), electric vehicles, and industrial uses. Wireless charging technology is expected to expand into these markets during the forecast period."

"Centuries ago, Nikola Tesla envisioned and pioneered the concept of wirelessly transmitting power over long distances through the Earth's ionosphere. In the recent past, wireless energy transfer has occurred by way of an electromagnetic (EM) field set to a certain frequency level. While transmission efficiency over longer distances is attained to an extent by this method, it becomes increasingly difficult when complicated pointing and tracking mechanisms are mandatory to maintain the right wavelength between the transmitter and the receiver. Another drawback to this approach is that any object that falls between the transmitter and the receiver impedes the beam, thus interrupting power transmission to a potentially harmful degree if the power level goes beyond a certain threshold point. Even though microwave frequencies could prove effective to transmit power over long distances through a radiated EM field, the aforementioned caveats still apply. The other possible way to wirelessly transmit power is by non-radiative fields. For instance, a transformer operates by magnetic induction drawing similarities to wireless power transfer. Energy transfer in a transformer happens from the primary coil to a secondary coil in the absence of a direct electrical connection. The same approach can be seen in inductive chargers found in electric toothbrushes, for example. However, for this functionality to operate smoothly, primary and secondary coils must be positioned in close proximity to one another."

The Trai statement said, the country added 8.81 million telephone connections (both wire and wireless) during June 2008 as compared to 8.46 million it added during May 2008. In the wireless segment, which includes GSM, CDMA and WLL, there was an addition of 8.94 million as against 8.62 million during May 2008.

NEW DELHI: India has surpassed the US to to have the world's second largest wireless network in the world after China with the addition of 10.16 million wireless subscribers at the end of March.

Members will not charge royalties for patents that are essential for implementing low power receivers. A wireless power receiver is a 'low power receiver' when it is a consumer product, such as a mobile phone or battery, capable of receiving no more than 5 Watt from a wireless power transmitter. These royalty-free licenses are available until 2014.
