A breakthrough in the design of signal amplifiers for mobile
phone masts could deliver a massive 200MW cut in the load on UK power stations,
reducing CO2 emissions by around 0.5 million tonnes a year.
Funded by the Engineering and Physical Sciences Research
Council (EPSRC), the Universities of Bristol and Cardiff have designed an amplifier
that works at 50 per cent efficiency compared with the 30 per cent now
typically achieved.
