摘要： A WiFi system with high-speed mobile voice and video data communication includes a plurality of mobile devices and a WiFi base station connected to a WiFi network. The WiFi base station transmits and receives packets to/from a mobile device within a time frame. The time frame is repeated at a predetermined period of time and divided into a plurality of variable-size time slots, each slot being assigned to a mobile device. The WiFi base station is based on an IEEE 802.11 standard to transmit/receive the packets respectively. Accordingly, all the WiFi base stations can use a single channel such that the handover between the WiFi base stations can be performed at high speed.

摘要： The present invention relates to a method and a system of wireless communicating voice data. When wireless communicating voice data, there is no need to collect the related information of the voice data into a multiple voice packet. Therefore, the ratio of the voice data in the multiple voice packet is increased remarkably to improve the efficiency of the wave band of the wireless communication. This method and the system therefore will provide high speed VoIP voice hand-over capability such that when the handset end-user is in high speed moving condition, the voice package can hand-over from one base station to next base station. For low power system such as WiFi, this method and the system thereof provides the best voice mobility capability.
