Expedience® Base Station

Expedience Base Station

High performance flexible solution for wireless broadband access

Motorola's Expedience Base Station delivers flexible, high-speed connectivity for fixed and nomadic wireless broadband access. Performance in the field and on the bottom line.

Designed for ease of installation in a number of different configurations, the flexible design of Motorola's Expedience Base Transceiver Station (BTS) will keep costs down as your system needs change by supporting a highly scalable system architecture for both rural and metropolitan areas. In conjunction with the Residential Subscriber Unit, Outdoor Subscriber Unit, Mobile Subscriber Unit, and PC Card CPEs, the BTS incorporates automatic adaptive modulation to maximize the capacity of the airlink over a wide variety of configurations and propagation conditions.

The BTS is a fully self-contained, environmentally-hardened unit. It offers maximum flexibility for installation at the tower or rooftop, in an equipment enclosure, or mounted on a pole. Connections to the unit include a single coaxial antenna feed, -48 VDC power, 10base-T, and GPS UTC (Universal Time, Coordinated) timing signal used to synchronize base stations installed in the same geographical area.

The BTS can be used in either sectored or omni­directional configurations, using standard antennas. Channel setup or changes can be done remotely us­ing the Motorola NetProvision™ Provisioning Man­agement System and requires no hardware changes at the site. Stacking of up to four base stations on a single antenna is easily accomplished using acces­sory combiner modules.

Maximum output power is 2 watts. An optional 5W configuration is available for the BTS-2500C, requiring the use of an accessory channel filter. The network interface to the Expedience base station is a standard Ethernet 10/100base-T connection, with a special weatherproof connector. Complete man­agement of the base station can be accomplished through either a local serial port, telnet session, web interface or using the SNMP-based Expedience Network Management System.

A complete on-site installation includes a transient voltage suppressor (TVS) module for each BTS. The TVS module also allows the BTS to be powered by -48V, +48V, or floating 48V power supplies. To power the base station in a cell, a dual redundant 48VDC power package is also available.
