Interference is becoming more common, and more difficult to deal with to ensure reliable link operation in poorly regulated or congested frequency environments.

WTM 4000 now includes a built-in spectrum analyzer, which gives you the power to:

  • Detect interference;
  • Determine alternative channel options;
  • Discuss elimination of the source with your regulator; and
  • Deliver your services, reliably.

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.

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.
  • Support for high capacity multi-channel configurations. For example, link capacities of >1 Gbps can be achieved using 4 x 28MHz channels (4+0), using 2048QAM modulations, for frame sizes of 1518 bytes or less.

WTM 4000 built-in spectrum analyzer Application note: WTM 4000 built-in spectrum analyzer
WTM 4000 Spectrum Analyzer feature is a built-in and license-free diagnostic feature to enable the user to check for potential interfering signals and measure the level of interference across the desired frequency range (limited by the diplexer bandwidth) and check the RSL (received signal level) of the interfering signal in 1.4 MHz steps.

Vodafone Fiji successfully deploys LOS MIMO link using Aviat WTM 4000 solution Case study: Vodafone Fiji successfully deploys LOS MIMO link using Aviat WTM 4000 solution
Vodafone Fiji needed a solution to provide over 2 Gbps of capacity over a distance of more than 6.5 kilometers, but there was only one problem: lack of frequency spectrum. Vodafone only had a single 80 MHz channel allocation in the 11 GHz band. Aviat was able to design a link using their WTM 4000 all-outdoor radio platform, employing Line-of-Sight (LOS) MIMO to quadruple the efficiency of the single available frequency channel.

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.

WISP Blog Series: High Quality Doesn’t Have to Mean High Cost

For new entrants and smaller WISPs, cost is often the major factor in infrastructure procurement. However, many WISPs who used to be in those categories are today enjoying significant growth, prompting them to rethink infrastructure investments as part of their overall business plan.

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
