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.

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.
