Introduction

The nanoBTS

The nanoBTS is a picocellular basestation operating in one of the GSM frequency bands and

complies with all the relevant ETSI / FCC specifications. A nanoBTS basestation is mounted on a

wall or ceiling, taking its power and traffic from a single 10/100 switched Ethernet connection.

The range of the nanoBTS exceeds half a kilometre in an uncluttered environment and inside

buildings can be expected to support users within a radius of up to 50m or more, depending on

the building construction materials.

The nanoBTS is physically linked to the BSC over an IP network and uses standard GSM

protocols to connect to the existing Public Land Mobile Network

(PLMN)

The diagram below shows the system architecture. Calls within the installation are passed over

the IP network and are handed over to the PLMN if the mobile leaves the installation coverage

area and is out of range of the ip.access basestations.
