First ensure that the core building block of your wireless network, the base transceiver station (BTS), is power efficient. Second, ensure that the overall base station site is globally engineered to maximize the reduction of its power consumption. Next, reduce the energy consumption of the network by minimizing the number of network radio cell sites.
Alcatel-Lucent Twin TRX Expands Network Coverage
Reducing the number of network cell sites requires maximum coverage per site and efficient network design. Alcatel-Lucent network design and planning teams can ensure optimized cell site deployment, and the Alcatel-Lucent Twin TRX dramatically expands the network coverage of each site, reducing the number of required network cell sites by 30 percent to 50 percent, depending on whether it is a rural or urban location.
Twin TRX
The Twin TRX:
- Provides best-in-class radio performance with Very High Equivalent Output Power up to 175W.
- Is an ultra-compact TRX module useable in all Alcatel-Lucent BTS cabinets.
- Houses two TRXs in a single box, reducing the TRX size by half, while doubling the functionality.

In the downlink path, the Tx diversity feature lets each Twin TRX module act as a super TRX, providing the equivalent of a very high-power transceiver.
Higher Output Power: TX Div provides up to 4dB gains in rural and 6 dB gains in dense urban environments. Result:
- In 900 MHz: Up to 113W in rural and up to 175W in dense urban environments
- In 1800 MHz: Up to 88W in rural and 136W in dense urban environments

In the uplink path, the Twin TRX offers two-way Rx diversity to offer a very good sensitivity. This level can even be increased thanks to the use of the optional four-way Rx Diversity.
In uplink limited and balanced environments, it brings more than 3 dB gains over 2RxDiv. Result:
- -121 dBm in dense urban environment
- -117.4 dBm in rural environment

High Coverage Solutions
The Twin TRX has successfully increased coverage effectiveness of GSM networks around the world. A case study in India proved that the number of cell sites could be reduced by 50 percent using Alcatel-Lucent GSM equipment.
