Radio platform delivers 2.5Gbps throughput per transceiver

February 22, 2017 // By Jean-Pierre Joosting
Aviat Networks, Inc., has announced the WTM 4000 radio platform, which provides up to 2.5 Gbps uncompressed throughput per radio transceiver and is purpose built for SDN.

Claiming to be the highest capacity ever delivered in a microwave radio, WTM 4000 offers a breakthrough in microwave backhaul performance for wireless networks. It is also the industry's first purpose-built IP-SDN radio with an integrated IP/MPLS software stack and built-in support for SDN protocols like NETCONF/YANG and OpenFlow for standards-based network automation.

Based on an advanced microwave RFIC and multi-core modem technologies the WTM4000 platform will have variants spanning all microwave frequency bands from 6 to 42 GHz. Using a new Adaptive Dual Carrier (A2C) feature, WTM 4000 can enable two channels over a single radio transceiver—which leads to two times the capacity of typical radios. Overall, the radio platform achieves lower power consumption, decreased weight, reduced cost per megabit and higher reliability.

WTM 4000 also enables maximum flexibility with its zero-footprint capability for mounting on building walls or outdoor infrastructure like lampposts—perfect for enterprise and urban small cell connectivity. Not only does it allow for more installation options but also drastically cuts equipment requirements and costs for shelters, cabinets, air conditioning and other indoor gear.

Additionally, WTM 4000 offers a Pay-For-Use (PFU) software scheme that allows operators to pay for software enabled capability only as they use it. PFU simplifies the management of hundreds of software licenses network-wide, significantly reducing operations complexity and lowering total cost of ownership (TCO).

"I am encouraged to see Aviat's focus on network automation and SDN," says Richard Webb, research director at IHS Markit. "Automation will be an essential tool to simplify networks and reduce OPEX. Support for SDN protocols will be essential to meeting operator goals of standards-based, network-wide automation across microwave and fiber technology as well as core and access network domains."
