3GPP define the Long Term Evolution to instead of GSM/EDGE and UMTS/HSxPA. LTE system compete with WiMAX. Both technology are defined in 4G system. LTE is enhanced with a new radio system access technique called Evolved UMTS Terrestrial Radio Access Network. Via this technology LTE is expected to improve end-user throughputs, security capacity, reduce plane latency and consequently offers superior user experience with full mobility.

1. In my experience, the Chrome and Firefox 3.0 are used so easy and fast. Their performance are better than IE Brower, but more resources, such as CPU, memory are needed. However, the resources are not a big problem, because the hardware device is cheap to be gotten it. I think that the SWF player do not be used in Chrome, because I can not use it from the following WEB site:http://www.yungching.com.tw/ . In my opinion, the Chrome and Firefox 3.0 will be updated and added more functions in the future.
