Ericsson has deployed a combined 2G, 3G and LTE cell site in rural Myanmar with a new solution designed to keep power consumption per site below one kilowatt.
The Psi rural coverage solution is designed to eliminate the need to have several radios in a coverage area for 2G, 3G and 4G coverage. It instead uses a single radio unit connecting three antennas together.
The radios, each of which handle a different access technology and frequency band, connect to a triple-band antenna.
Psi is also deigned to reduce power consumption in remote areas where power grid supply is often inadequate or unavailable, reducing the cost of operation for rural and low-capacity deployments.
Ericsson said Psi is named after the Greek character in the shape of a fork with three teeth, representing the triple-band antenna design.
