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.

High Capacity + Availability: Multi-Band is the right solution for 5G backhaul

Multi-Band, not microwave or millimeter-wave, is the 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.

Multi-Band (70/80GHz + 6-23GHz) Backhaul
An analysis of viability of multi-band links: where/when/why…?

Multi-band backhaul links consist of running multiple channels at different frequency bands (typically 70/80G + 6-23G) on a single link to improve capacity and reliability. These links essentially operate like an extended ACM solution – giving more reliability than E-band and more capacity than the lower frequency channel operating independently.

Options and Strategies for Maximizing Your Network Potential

In recent years the microwave industry has made great progress in capacity evolution – actually we’ve seen somewhere in the neighborhood of 30 times increase in microwave capacity over the past 10 years. In doing so, microwave has proven itself to meet the capacity of LTE and LTE-A applications and with some new evolutions to enable multi-gigabit links, is now well positioned for 5G as well.

Multiband Microwave: It's Not Just for 80GHz Links - Applications in Traditional Microwave Bands

Multiband backhaul links consist of running multiple channels at different frequency bands on a single link to improve capacity and reliability. Currently there are several products in the market (or in development) that are using a combination of E-band and microwave frequencies. An alternative is to take advantage of the larger channels of higher frequency bands (ex: 32 GHz) and better RF performance of lower frequency bands (Ex: 11 GHz) within the traditional microwave range.

Wireless Backhaul is Not Dead Yet

By Stuart Little, Director of International Product Line Marketing, US

This Halloween, zombies aren’t the only thing coming to life. Evolutions in e-band and multi-band mean wireless will play a crucial role in the rollout of 5G.

5G is coming (and hopefully it won’t be accompanied by White Walkers) and will bring with it tremendous challenges for network operators, and no less critical will be backhaul, where needed capacities will grow from the hundreds of Megabits to multiple Gigabits. In their latest Microwave Outlook (from December 2017), Ericsson forecasts that by 2022 the typical backhaul requirement for a high-capacity radio site will be in the around 1 Gbps, increasing to as much as 5 Gbps towards 2025.

E-Band Global Regulation Roundup

Because of need for higher capacities, the trend toward shorter link distances for mobile backhaul and declining product costs, 70/80GHz (i.e., E-band) solutions are gathering significant interest for mobile backhaul and enterprise access applications. However, because these frequencies are new to most people, there is little understanding of costs and other issues related to licensing the 70-80GHz spectrum.
