Why “Open” Cell Site Gateways?
• Updates to existing equipment is needed as mobile backhaul usage surges with 5G deployments on the horizon. Sitting at the edge of the network the Cell Site Gateway is high volume deployment product and a natural location for Carriers to start enjoying the benefits of open networking.
• Removal of single vendor lock in and traditionally slow technology roadmaps from incumbents
• Truly open Hardware that can run different commercial and open source operating systems offering freedom of choice to the operator
• New operating systems choices that provide extensibility and the execution of arbitrary agents
• Removal of vendor lock in on pluggable optics and cables leading to lower capex

Cell Site Gateway High Level Requirements
• Outside plant compliant with operating temperature -40C to +65C
• 1RU 19” Rack mountable
• Maximum equipment depth 300mm
• Redundant power supplies and fans
• Support clock synchronization techniques incl IEEE 1588 and SyncE
• Support for local timing inputs/outputs GPS, ToD, 1PPM, etc.
• Ability to support long haul optical modules
