Complete Baseband Processing Solutions

With more than two decades of commercial experience, ArrayComm has a proven reputation of bringing complete base station products and systems to the market on a variety of air interfaces. This unique combination of expertise and experience provides the foundation for our BasePort™ line of complete 4G& 5G PHY products.

BasePort products deliver all of the baseband PHY processing software needed for implementation on a target hardware platform, integrated seamlessly with layer 2/3 protocol stack for superior performance. ArrayComm’s commercial experience working with most SoC/processor platforms ensures a smooth integration process.

Development teams are being asked to do more with less. At the same time, investment in new platforms is needed for ORAN and white box solutions for 4G & 5G wireless broadband networks. ArrayComm delivers fully validated, commercial-ready BasePort PHY software pre-integrated with remote radio units and layer 2/3 protocol stack for all tiers of 4G & 5G base stations with all layer split options. This enables equipment suppliers to keep pace with the breadth of market demands with high-performance products.
