Ericsson yesterday revealed new antenna-integrated radio (AIR) solutions systems called Hybrid AIR and Interleaved AIR. The systems are designed to decrease site footprint and expand the capacity for 5G rollout. The company claims that no extra physical space is needed at existing sites and when deployed with Massive MIMO, communications service providers can deploy mid-band 5G with the new solutions “faster and on a larger scale.”
Per Narvinger, Head of Product Area Networks, Ericsson, said: “It’s a footprint issue. At some network sites, size literally is everything. Communications service providers globally often have limited possibilities to increase the space occupied by network equipment. They need solutions that fit in existing sites and still provide great performance. With the Hybrid AIR and Interleaved AIR solutions, we can help our customers to quickly deliver the benefits of 5G Massive MIMO to more end users. This launch also shows the effectiveness of fully integrated Kathrein Mobile Communication products in our Ericsson Radio System.”
Narvinger said in a simulated calculation by Ericsson they found the upgrade to Hybrid AIR or Interleaved AIR with Massive MIMO can result in up to seven times greater mobile broadband capacity than currently available from existing multiband antennas. The capacity gains come from improved Frequency Division Duplex (FDD) spectral efficiencies, new FDD bands and added Massive MIMO mid-bands. The new AIR solutions also boost 4G capacity, he said.
