Companies complete interoperability testing for mesh backhaul over HFC to deliver mobile broadband applications.

Narad Networks and Tropos Networks today announced successful interoperability testing of their complementary solutions.

The combined solution provides mesh network operators with a new option to backhaul mesh WiFi traffic within the metro area. Tests using Narad's switched Ethernet-over-coax solution and the Tropos 5210HFC MetroMesh router demonstrated aggregate performance exceeding 20 Mbps of symmetric capacity with low end-to-end latency. This level of performance will enable operators to offer mobile broadband applications and services such as mobile video and instant messaging while avoiding the need for costly new fiber construction.

"Metro WiFi networks are a logical way to extend the functionality of the cable network to mobile users throughout a metro area. As part of their ongoing mesh WiFi deployments, cable operators require high capacity and low latency backhaul technologies which leverage the installed cable plant," said Michael Collette, CEO of Narad Networks. "The Tropos/Narad solution will allow cable operators to efficiently integrate a mesh network into their existing HFC plant, which in turn will help minimize the capital and operating costs of the network."

"Supporting multiple mobile broadband applications is a key opportunity for cable providers, and this solution provides an immediate way for them to extend their core value outside of the home," said Chris Rittler, VP Carrier Sales and Business Development of Tropos Networks. "A multi-service architecture is a key value of a Tropos MetroMesh network, and Narad's support of multiple VLANs enables cable operators to provide multiple revenue generating wireless services over their existing cable infrastructure."

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.
