Ericsson says it has successfully deployed a base station in rural Myanmar that uses three frequency bands, supports 2G, 3G and 4G, and runs on less than 1 kilowatt of power.
The deployment uses Ericsson’s Psi rural coverage solution to keep total power consumption per site below one kilowatt (kW). The solution eliminates the need to have several radios in a coverage area, and instead uses one radio unit that connects three antennas together to provide coverage.
The radios in this scenario handle one access technology each and connect to a triple-band antenna. This maintains voice services and enables mobile broadband over LTE where these services were not previously available.
Ericsson says that by bringing down the number of radios on a network, the solution significantly reduces capex and total power consumption, which also reduces opex – both of which are essential features for rural and low-capacity deployments.
In remote areas like Myanmar’s countryside, power grid supply often remains the biggest challenge in maintaining coverage. This leads to heavy dependence on unreliable diesel generators. The Psi solution provides a more reliable and cost-efficient alternative, Ericsson says.
