Demand for mobile data is soaring, and microwave is seen as the primary transport medium in rural and suburban areas. Aviat’s WTM 4000 enables double capacity (2+0) microwave links by housing two transceivers, two diplexers, and a 3dB coupler in one compact all-outdoor solution.
With the current landscape of network economics and challenges associated with capacity and spectrum, having multiple tools for link deployments, capacity growth, and future-proofing are necessary. In this blog, we’ll discuss the concept of Microwave Multi-Band, or the use of two different microwave frequency bands over one link, and specifically the combination of 6 GHz and 11 GHz.
With tower outsourcing increasing, operators can minimize tower lease costs by reducing the size of their microwave antennas with higher system gain radios.
Most radio buying processes haven’t changed for years. Some orders are still placed by picking up the phone, emailing a request, waiting for a response, and then juggling multiple POs. It’s such a long process to manage from start to finish. Aviat Store solves all those issues and more.
One of the most significant contributors to the total cost of ownership of a microwave transmission network is the antenna sub-system.
TWS technologies, based in the Netherlands, are always looking for new systems to enable reliable connections for their customers, anytime, anywhere.
Safaricom, the largest telecom company in Kenya, recently selected Aviat’s WTM 4800 multi-band radio platform to support their 5G backhaul rollout.
In 2015, PNG outlined its Vision 2050, committing the government to promote the social and economic development of the nation by that date. National leaders spoke of W.W. Rostow’s five-stage model of development. The second of those stages is all important: the building of infrastructure necessary for the success of all sectors of economic and social life, which includes manufacturing, technology, transportation, and communication.
Are you considering deploying microwave links in your network? Instead of deploying 15, 18 or 23 GHz why not try WTM 4800 Multi-Band with 80/xxGHz. You can replace your microwave links with Multi-Band which combines E-Band and traditional microwave (15/18/23GHz) on a single link over a single antenna to drastically improve capacity that can be typically achieved by microwave alone.

In the past years, a few microwave vendors have introduced ‘sub-band free’ RF outdoor units into the market. The main claim of these radios is that a single hardware variant can be deployed in any frequency sub-band, simplifying and lower costs involved with ordering, deployment and sparing of microwave networks.
However, these new radios are not available in all bands and come with a number of limitations, including lower RF performance, larger size, and weight, higher cost, limitations in modulation and channel sizes, amongst others.
This large western US state had a longtime relationship with a microwave radio vendor and would have continued buying from them if their radios and support evolved with the State’s needs. However, over time its needs changed and it had to have more capabilities from its communications network. But it did not want to unnecessarily build new sites and erect costly new towers.
85 mobile operators were selected and surveyed globally, including a good cross-section from both developed and emerging markets. The respondents were screened to ensure that they all had a stake in microwave-specific backhaul: 93 percent had deployed microwave and the rest had plans to deploy it. In fact, 45 percent were categorized as heavy microwave users—those where more than 50 percent of their cell sites were served by microwave backhaul.
So we asked this select group, which consisted of mostly planners, engineers and strategy leaders, “What is the biggest challenge your company faces regarding the future development and deployment of microwave backhaul?”
The results were interesting in that “total cost of ownership” actually eclipsed “increasing capacity” as their biggest challenge, as shown in the pie chart of survey responses below.
