Vodafone Egypt hopes to reduce the energy consumption of its 3G network after testing a first-of-its-kind Psi-coverage solution from Ericsson.

Psi-Coverage reduces the energy consumption of 3G networks in less densely populated areas while maintaining the quality of the mobile broadband coverage. The solution reduces the number of radios needed to cover a given area by a ratio of three to one.

Where a network would have required three radios in a coverage area, Ericsson’s Psi technology uses one radio unit that connects three antennas together. The name of the solution is based on the Greek symbol for PSI, which has the shape of a fork with three teeth (Ψ), representing the set-up of the network.

In the first field implementation, Psi-Coverage reduced the network's energy consumption by 40%. Tony Dolton, chief technology officer at Vodafone Egypt, said: “Psi-Coverage proved to be successful during testing, it reduced power consumption substantially and helped in saving OPEX/CAPEX costs. We are pleased to have partnered with Ericsson yet again on this opportunity to demonstrate technology leadership.”

Anders Lindblad, President of Region Middle East and Africa, Ericsson, says: “Our continued partnership with Vodafone Egypt has allowed us to take a huge leap in deploying solutions for more sustainable mobile networks. Psi-Coverage allows operators to reduce carbon footprint while maintaining quality of services to their customers.”
