Axerra and Narad Partner on Wireless Backhaul over HFC

Axerra Networks and Narad Networks have partnered on a T1 backhaul solution over HFC. The combined offering delivers an end-to-end latency of less than 8ms, enabling Multiple System Operators (MSOs) to satisfy the stringent differential delay requirements of mobile wireless backhaul.

The solution leverages Axerra's AXN Pseudo-Wire platforms and Narad's switched Ethernet over Coax solution, avoiding the need for fixed wireless solutions or costly new fiber construction.

Axerra Networks' family of AXN Pseudo-Wire Gateways and Access Devices furnish full-service capabilities over the HFC and fiber infrastructure of cable networks, including leased line T1 PCM Voice, T1 Private Line Data, Ethernet Private Line, native Frame Relay, ATM, HDLC, and IP services.

Axerra features low latency and high-precision clock recovery capabilities that support T1 Business Services and Mobile Wireless Backhaul applications.

Narad's Ethernet-over-Coax solution provides up to 100 Mbps x 100 Mbps of additional bandwidth over each coaxial cable span. In combination with Narad Ethernet switches, these 100 Mbps symmetrical links can be switched onto the coax plant at multiple points to provide Gigabits of symmetric bandwidth per node. Narad's switched Ethernet-over-Fiber solution provides Gigabit fiber capacity while making optimally efficient use of existing fiber plant. Narad's Ethernet-based outdoor switches support fiber, coax and wireless transmissions.


Pseudo-Wires for Mobile Wireless Backhaul over Carrier Ethernet
continued evolution of mobile wireless services is toward technologies
that are intrinsically packet-oriented, such as HSDPA and HSUPA, and
indicative that packet access networks, rather than TDM-based T1s and
E1s, are the logical transport for backhaul in the RAN.
