ADCP-75-246 • Issue 1 • 6/2008 1 INTRODUCTION The FlexWave 2x1 microBTS is an environmentally hardened outdoor base station solution that supports GSM/AMR voice traffic and GPRS/EDGE data traffic. An Internet Protocol (IP) backhaul provides the interface between the microBTS and the Base Station Controller (BSC). All voice and data traffic and all operation and maintenance functions are transported by the IP backhaul.
ADCP-75-246 • Issue 1 • 6/2008 • • • • • 2.1 Provides Power Over Ethernet (POE) to the IP backhaul device Provides an RF interface (antenna port) for the base station remote antenna. Provides an RF interface (antenna port) for the Network Listen antenna. Accepts AC power input.
ADCP-75-246 • Issue 1 • 6/2008 2.6 Base Station Antenna Cable Connection The base station antenna cable connection is through one 50-ohm N-type female connector. The microBTS includes an internal duplexer which allows a single antenna cable to carry both forward and reverse path RF signals between the base station antenna and the microBTS. An externally-mounted lightning protector is available as an accessory. The surge/antenna connector on the lightning protector is an N-type female connector.
