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.
Both Eclipse and the IRU 600 offer market-leading solutions to network operators who need robust, flexible features such as extra high power (EHP), hybrid transport of TDM and IP traffic, superior system gain, and the latest security technologies.
In both products, the enhancements consist of new firmware added to existing modules. The firmware is a highly efficient way to enable true native transport of both TDM and IP traffic. It’s like having two radios (from two different technology eras) moving traffic seamlessly across the same network expanse—without the cost of two radio systems and with easy, cost-effective new ways to migrate your network to current transport technologies over time.
As you may have seen, Aviat has been very vocal about the benefits of extra high power (EHP) radios on network designs. Most of these discussions have been about the cost savings benefits of high output power in the form of more distance, smaller antennas, or more capacity.
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.

You may have noticed we’ve been talking a lot lately about our new 39dBm EHP radio (the most powerful digital microwave radio ever built by the way). We’ve been getting a phenomenal response to this product mostly because of the real business benefits it delivers…benefits largely related to the antenna.
As a rule of thumb in microwave backhaul, the more powerful the radio (i.e., system gain) the smaller the antenna has to be (i.e., overall diameter). More than any other factor, smaller antennas drastically lower the total cost of ownership for microwave.
