This paper presents a transportable and rapidly deployable network system, which can be used to provide local voice, video and data connectivity for critical communications in remote locations and Internet connectivity through commercial mobile network, if available. The network is a stand-alone system, which is independent of external electricity and Internet. It is built with commercial off-the-shelf equipment and software. This paper presents trials of a local tactical voice service, a TETRA-compatible push to talk application, and Licensed Shared Access evolution spectrum manager along with radio signal measurements on 700 MHz and 2300 MHz frequency bands.
