T-Mobile Hungary has commissioned the first cellular base stations in the country to be operated with hydrogen-based Proton Exchange Membrane (PEM) cells--a process where electrical energy is generated when hydrogen ions merge with oxygen.
The company claims the primary use of PEM cells will be for the supply of emergency power to base stations and, given it has no moving parts and is silent in operation, T-Mobile expects the technology to offer a realistic ROI by reducing energy consumption and operational costs.
Separately, Huawei has confirmed it has signed a contract with T-Mobile in the Czech Republic to replace all its current base stations and base station controllers--a total of 4500 base stations and 150 controllers. T-Mobile said that some of the equipment had been working for more than 12 years, and was becoming increasingly difficult to upgrade in order to provide significantly higher capacity.
