Cambium Networks Introduces cnMadusa - Massive MIMO Makes More Mbps

We just finished a training on Cambium Networks new cnMedusa technology that’s available in their new PMP 450m and it’s pretty cool. They’ve introduced Massive MIMO, which is basically a combination of multi-user MIMO withsector beam forming technology. By combining the two technologies, Cambium's cnMedusa can deliver 400Mbps of throughput on a single 20 MHz channel. This becomes really important when you are trying to increase your throughput in an area where radio spectrum is already crowded.It makes the most of your spectrum used for your single end-to-end radio connection and its specific RF spectrum.

For those of you who don’t know, Massive Multi-User MIMO (Multiple-Input, Multiple-Output) is a more advanced MIMO techniques that use multiple antennas and beamforming techniques to transmit and receive data. It’s complicated to achieve this technology because each node must be able to differentiate the data transmitted from one antenna to that transmitted from another in the same radio channel using sophisticated channel estimation and sounding techniques. As the number of antennas and the corresponding number of data streams in a MIMO system increase, the complexity of tracking each one of these signals, end-to-end, increases. Systems using Massive MIMO require highly advanced signal processing and system design for the network to function well as the number of antennas increases.

The Cambium Networks PMP 450m is a first commercially available, cost-effective fixed wireless broadband access platform that provides Massive Multi-User MIMO (Multiple-Input, Multiple-Output) technology on a platform that is less than 23” x 25” platform. This is a huge increase in spectral efficiency and their roadmap calls to achieve 1GB per sector.

And to make this even cooler, getting this cnMedusa technology can be implemented with existing PMP 450 subscriber modules because the upgrade will only be completed on the access point. This means you can multiply your network capacity without any hardware changes or upgrades. And to make things even better you can add the cnMedusa technology without frequency replanning. Just upgrade your current 14.2 current firmware and you’re set! Cambium has even added cnMedusa to LINKPlanner, so you can easily see what sort of upgraded capacity you’ll achieve using your current deployment of Cambium products.
