WTM 4000 benefits

  • Save money – less cost per bit, less power consumed per bit than any other microwave radio. Plus all-outdoor deployments reduces power, space and cooling costs of indoor equipment
  • Meet capacity demands – ultra high capacity to protect your network from pending traffic growth
  • Prepare for the future – supporting a variety of SDN protocols, WTM 4000 is the industry’s first ever radio purpose built for SDN and IP/MPLS networks

The most capable microwave radio ever.

Check out this video for more details about the Aviat WTM 4000.

WTM 4000: The industry’s highest capacity microwave radio

Highest capacity in single transceiver radio, exceptional price / performance with:

  • 2.5Gbps (single radio – 2x112MHz channels)
  • 1.5Gbps (single radio – 2x80MHx channels)

Adaptive dual carrier (A2C) feature enables 2 channels over single transceiver leading to 2x more capacity than single header radios or ½ the transceiver hardware compared to dual-header radios. Which means, less cost and power consumption per bit… and of course more capacity.

Other capacity features include:

  • 112MHz channels,
  • 4096QAM,
  • Header compression and other capacity enhancement techniques.

MPLS + SDN + NFV World Congress Public Multi-Vendor Interoperability Test 2017 White paper: MPLS + SDN + NFV World Congress Public Multi-Vendor Interoperability Test 2017
The European Advanced Networking Test Center and Upperside Conferences invited interested vendors to our public multi-vendor interoperability test and showcase at the MPLS + SDN + NFV World Congress 2017. All 15 participants, including Aviat Networks, were able to actively shape the program and set the course during the preparation of the hot-staging. The hot staging itself was a closed doors fully immersive test event taking place at EANTC’s lab in Berlin, with the whole set-up being transported and demonstrated live at the Paris conference. Successful results are published in the white paper.

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
