Multi-Band – The Future of 5G Transport

Thinking about E-Band or traditional microwave links?
Consider Multi-Band instead!

The Problem

E-Band Lacks Availability in Some Cases

  • Limited reach of 80GHz – maximum link distances only up to 2 or 3 km, or less
  • Risk of outage – high precipitation can take down an 80GHz link for an extended period
  • Difficult to align E-Band antennas – raises installation complexity and costs
  • E-Band is susceptible to pole sway, due to narrow antenna beam-width – more outage risk

Traditional Microwave (15/18/23GHz) Lacks Capacity in Some Cases

While traditional microwave has been a valuable backhaul alternative for years, the spectrum availability and channel widths inherently mean these bands will have difficulty scaling capacity to meet the needs of 5G – approaching and exceeding 10Gbps.

More Availability is Needed – Especially for the Future of 5G

5G is all about use cases which promise to be new revenue streams for the operator and are critical for operator financial success. Many of these use cases deal with critical applications (connected/autonomous cars, industrial IOT, M2M, public safety applications, etc.), which require very high availability from the transport networks.

These issues come down to one main theme – traditional wireless transport options lack the capacity and availability for wide-scale deployments for 5G networks.

The solution: Multi-Band

What is Multi-Band?

Multi-Band involves combining E-Band (70-80GHz) with traditional microwave (6-42GHz) on a single microwave link, usually with a single antenna on each end. Unlike E-Band or Traditional Microwave, Multi-Band provides:

  • Better capacity: Multi-Band realizes capacity benefits of E-Band, & solves shortcomings. Multi-Band improves the capacity of traditional microwave by adding a high capacity E-Band channel in parallel. Improve link capacities with Multi-Band by up to 10x the capacity of a standalone 15/18/23GHz solution. You can add the capacity right away or just leave the E-Band available and turn it on via software when you’re ready for more capacity.
  • Immunity to environment issues: Your most important traffic is now immune to outages due to rain and pole sway – 99.999% availability, up to 2.5 Gbps.
  • Extended reach: With Multi-Band, you can extend the reach of your E-Band links up to 6, 8, maybe 10 km
    Simple antenna alignment: Multi-Band enables simplified antenna alignment – essentially the same alignment experience as a regular microwave link

Aviat Makes Multi-Band EASY

Most Multi-Band solutions on the market are complex and costly, requiring 2, 3 or even 4 separate boxes. Plus, these solutions offer no easy way to plan and design new complex Multi-Band links.

Aviat has the industry’s only viable Multi-Band option – including a single box Multi-Band radio with direct antenna mount as well as the industry’s first and only Multi-Band link design solution in Aviat Design.

The bottom line:

With Aviat’s single-box Multi-Band solution, you can significantly improve capacity by up to 10x (compared to traditional microwave) and virtually eliminate outages (when compared to e-band). At a cost that makes sense… Why would you not consider that?

The new WTM 4800 radio is about simplicity. The Multi-Band variant simplifies fronthaul/backhaul sites by reducing current configurations of multiple radios, cables, and a coupler to a single integrated radio unit. Additionally, the Multi-Band link planning tool on the AviatCloud simplifies the radio link design and planning down to six clicks of a mouse.

Emmy Johnson

Founder & Principal Analyst, Sky Light Research

Aviat recognized the need for cost efficient, reliable 10 Gbps backhaul and capitalized on it with the WTM 4800, which is a unique single-box Multi-Band radio design.  A single-box Multi-Band radio not only provides reliability, distance, and capacity, but also helps solve the OPEX business case by streamlining the amount of equipment (and thus cost) historically required for a Multi-Band solution.  Sky Light Research expects E-Band to be the sweet spot of the microwave radio market over the next five years, growing more than 200 percent by 2023.

Don Frey

Principal Analyst, , Ovum (an Informa company)

Service providers need lower total backhaul cost per gigabit, especially with 5G requiring less latency and greater transport bandwidth. Aviat Networks continues to lower the cost of installation, planning and operation by being first to provide an integrated Multi-Band 10Gb microwave product and a unique Multi-Band link design tool. In the next five years, Service providers will spend over $12B on 4G and 5G microwave backhaul including multi-carrier or multi-band equipment, so simplifying the design will be a winning strategy for service provider deployment.

Richard Webb

Associate Director of Mobile Transport Research, IHS Markit TMT (an Informa company)

Multi-Band is an important technology in meeting the capacity, latency and reliability requirements of 5G transport,” states Richard Webb, Associate Director of Mobile Transport Research at IHS Markit TMT (an Informa company). “Aviat’s new WTM 4800 single-box Multi-Band product offer microwave users flexibility for 5G backhaul applications, allow them to minimize the number of devices they need and control capital, deployment and operational expenses. Aviat Store and Aviat Design are also very important pieces of the Aviat value proposition.

Some multi-box Multi-Band solutions currently available on the market fail to provide a seamless switchover between the traditional microwave and E-band frequencies when the E-band portion becomes unavailable—leading to reduced capacity and the need for manual intervention to correct the link’s performance. This paper intends to demonstrate how Aviat’s Multi-Band solution overcomes these limitations to support hitless traffic aggregation and restoration.

High Capacity + Availability: Multi-Band is the right solution for 5G backhaul White paper: High Capacity + Availability: Multi-Band is the right solution for 5G backhaul
Why? Microwave bands are limited in capacity, particularly in countries and bands where spectrum is limited due to congestion. Even if you can get additional frequencies, scaling capacity means aggregating multiple channels that results in high equipment costs and potentially expensive recurring spectrum fees. E-Band alone is not sufficient either. With more bandwidth available that enables higher capacities, E-Band suffers from a number of potential limitations, from short link distances and high susceptibility to rain outage and pole/tower sway to difficult and time-consuming installation/antenna alignment.

Is traditional microwave dead? With the advent of Multi-Band, it could be. Why accept an old solution when you can have so much more by combining E-Band and traditional microwave into a single-box unit. Governments are taking action across the world to connect homes and businesses in rural areas to the rest of the world. From the 7-year action plan devised by National Broadband Ireland (NBI) to the Federal Communications Commission’s (FCC) $9.2 billion newly implemented Rural Digital Opportunity Fund, there is a worldwide focus on the connectedness of rural areas. As capacity demands increase rapidly for rural broadband networks, a better solution than traditional microwave is needed.
