Ethernet TCP/IP big bandwidth 20Mbps data transmitting for NLOS 10km
Introduction
ST-3027TDA This two-way IP integrated communication system
integrates the functions of network switching, digital baseband
processing, up and down frequency conversion, power amplification,
and so on. The wireless communication makes IP network coverage
extend to remote mobile terminal, and transparent transmission of
IP data between faraway devices is realized.
Users can easily obtain various services such as video
transmission, web browsing, data and file transmission and remote
control through mobile Internet devices.

System Application
Wireless network organization among multiple communication vans in
city
Networking among vans, that is, networking among mobile radio
stations, has two modes: when communication vans get close to each,
for instance, in a motorcade, the van always connected to its
adjacent van and realizes wireless network communication among all
nodes by skipped connection; if the van gets far from each, at
different corners of the city, such as the important sports game
safeguard activity requires so many security staffs for multiple
venues, in such case the communication among vans rely on base
station roaming service.
