Wi-Fi Skype

Google和Skype聯手投資建立Wi-Fi共用網路
互聯網巨頭Google和eBay旗下的Skype將聯合向一家新興企業投資。這家新興企業計劃幫助Wi-Fi熱點的擁有者對Wi-Fi接入收費。此舉可能遭到互聯網服務提供商的強烈反對。


解決電力難題 智邦推全球首支Skype Wi-Fi手機
值得注意的是,Wi-Fi手機雖被認為是未來的明星產品,但單價過高、電力消耗等問題都讓外界對Wi-Fi手機前景多有疑慮,而此次智邦推出的SkypeWi-Fi手機待機時間可達20小時以上,而通話時間可達4小時,已可算是解決部分Wi-Fi手機電力消耗的問題,至於在售價方面,智邦此款Wi-Fi手機初步預計的零售通路售價約在150美元上下,也低於先前部分Wi-Fi手機售價動輒超過新台幣1萬元以上的售價。

L2C GPS & GPSoverIP

US Upgrades GPS Signal
The L2C signal increases power output and accuracy coming from the satellites. This will allow mobile devices to obtain a more accurate location while using less power than before.


L2C GPS
The new signal is known as L2C and is designed with higher power so GPS receivers will work better in areas surrounded by large buildings as well as indoors. This will facilitate GPS chipset makers to produce receivers that use less power to acquire the same signal strength, opening the doors to have GPS devices incorporated into smaller and lower power devices.


美国GPS讯号提升工程
美国政府宣布一项GPS讯号提升工程。GPS手机和其他使用到GPS备件的用户现在可以开心的使用更清晰的L2C讯号。这可以以一个更廉价的能源成本来确保更准确的定位。尽管L2C今天已被启动,那些备件还是需要一个最新的晶片来体验完全提升版的乐趣。


Understanding L2C ( L2 ) GPS
“The activation of the L2C signal in January 2006 will be of great benefit to the civil community, but they will be using this signal at their own risk until the command and control of L2C is realized in the Fiscal Year 2013 timeframe." said Colonel Jester, Chief, Space Operations Branch, Air Force Space Command.





GPSoverIP web service and trackable jacket
March 12, 2006 “Mr. Bond, this jacket takes some beating! Its wearer can be tracked down in real time using the high-precision GPS (Global Positioning System) - even inside buildings.” It’s easy to picture Q helping 007 slip on the jacket but in fact it’s not a work of fiction but a new product developed by German company GPSoverIP GmbH and partner Interactive Wear AG.


GPSOverIP shown at CeBIT 2006
GPSoverIP (Global Positioning System over Internet Protocol) is a novel technology which is comparable with VoIP (Voice over Internet Protocol) and which provides geographical coordinates over the Internet. GPSoverIP solves the problems which arise in connection with GPS transmission by sending the geographical data to the GPSoverIP gateway in compressed form.
