'Green' energy powers Motorola's GSM base station

Motorola Inc. has completed its one-year trial of running a remote GSM base stations (BTS) using alternative power systems. A combination of solar cells and wind turbines, based on the trial, can generate 1,200W in a continual cycle, which is enough to drive a mid-sized BTS and support a microwave backhaul installation.

Operators are faced with the challenge of powering BTS sites in both developed and emerging markets either due to high costs or difficulty of provisioning mains electrical power. The green-powered BTS, part of the company's Reach GSM portfolio, is expected to replace or reduce the load on mains power and can also remove the need for power generators that require continual refueling and security.

"In areas such as central Africa, operators can spend as much as two-thirds of their operating costs on diesel power," said Mohammad Akhtar, vice president, global product management GSM/UMTS, Motorola Sales and Services Inc. "Using eco-powered BTS can help operators to lower operating costs. This reduction in operating expenditure can be critical for operators in emerging markets when building networks that reach customers in remote locations."

During the trials, Motorola used a combination of solar and wind power to run a GSM base station and charge batteries that kick in when the solar or wind power is insufficient.

The company collaborated with Bristol, Bath and Surrey Universities to run the year-long test at its GSM facility in Swindon, United Kingdom.
