AirWalk Technology

The AirWalk Small Cell Solution combines advanced CDMA radio technology with IP network capabilities for the most advanced and cost-effective solution for network expansion

The compact size and flexible power options supported by AirWalk CDMA Small Cell IP-RAN products provide much greater installation flexibility compared to traditional cellular base stations. Operators benefit from lower installation and operating costs while ensuring support for the most current network features and capabilities.

All-IP backhaul provides efficient transport or signaling and media over lower cost packet networks. Operators benefit from reduced costs compared to traditional T1/E1 circuit connections. Both 1xRTT and EVDO backhaul transmissions can be combined over a single IP link. Ethernet connectivity with IPSec options support interconnection to both private and public IP networks while providing network security.

AirWalk’s distributed controller architecture supports essential features such as seamless hand-off between small cell devices. The unique AirWalk integrated RAN solution provides traditional centralized controller functions such as soft handoff on a peer-to-peer basis. Core network switches are relieved from any processing burden due to both hard and soft handoffs within the radio network, thus improving overall efficiency and capacity. Operators benefit from the elimination of expensive centralized base stations controller (BSC) or radio network controller (RNC) components. Network reliability and operating costs are also improved with the elimination of the single point failure central controllers.

AirWalk distributed architecture controller provides unlimited RAN network scalability. Operators benefit from simpler network planning and lower latency through distributed signaling. Each new base station added to the network brings additional controller processing capability which supports expansion of the RAN network in a smooth and linear fashion.

AirWalk supports 3GPP2 open interfaces on all IP-RAN products. 1xRTT core network connections comply with IOS 4.x/5.x standards. Data network connections comply with A10/11 and A12 interfaces. Femtocell and Picocell products provide IOS or SIP based connections to soft switches or 3GPP2 X.59 SIP connections to convergence servers. Full air interface support is provided for IS-95, cdma2000, 1xRTT, EVDO Rev 0, Rev A and Rev B air interfaces to provide maximum deployment and growth flexibility for operator deployments.
