Wireless broadband equipment vendor Proxim Wireless introduced a 4G backhaul product line for both the point-to-point and the point-to-multipoint markets in the commercial, wireless ISP and government sectors.

The kicker, according to Proxim, is the products' performance requirements, which exceed standards bodies’ requirements for 4G networks. Today, the products deliver data rates up to 300 Mb/s, but versions coming off the production line in the fourth quarter will double those rates to 600 Mb/s.

"Every time you introduce a new piece in the network, you have to account for latency," Proxim CEO Pankaj Manglik said. "It has to be well below 10 milliseconds. ... We're offering a range of more than 70 kilometers with latency running 1 to 2 milliseconds."

Specifically, Proxim is offering the Tsunami QB-8100 point-to-point and the Tsunami MP-8100 point-to-multipoint solutions. Both products support a range of frequencies, including public safety's 4.9 GHz band. Proxim has been supporting government applications such as IP video surveillance and traffic monitoring. With the new 4G products, public-safety entities will be able to support a larger number of high-definition cameras, Manglik said. He added that while the average video surveillance camera has a bandwidth requirement of 5 Mb/, HD video has a requirement of more than 10 Mb/s.

NetUnwired USA, a provider of wireless backhaul for broadband networks, successfully tested the Tsunami MP-8100 with existing surveillance cameras on the Golden Gate Bridge. One differentiating component is the dual gigabit Ethernet ports with Power over Ethernet (PoE) in/out power, which eliminates the need for a separate line for power. On the Golden Gate Bridge, where no light poles exist, that capability is needed, Manglik said.

"It's a feature that is largely requested in the field, and we are the first to have that out to power video cameras," said Robb Henshaw, director of marketing with Proxim.

Proxim also is targeting the commercial mobile carrier industry and is expecting to cash in on some of the stimulus money the federal government is doling out to entities looking to deploy broadband in rural areas.

For commercial operators and public-safety entities deploying Long Term Evolution (LTE) networks with significantly higher data speeds than the current generation of technology, the demand for more capable backhaul is expected to skyrocket. Rural broadband deployments will require high-range backhaul solutions as well.
