I see from the FCC authorizations page that QWP-30450M, the 3 GHz Medusa, has received an FCC approval (permissive change) with the following sentence: "This device supports LTE of 5, 20, and 40 MHz bandwidth modes for TDD LTE Band 48." And the power limits are quite reasonable (it's hard to get approved for anything near the theoretical +37 dBm/MHz maximum power), and the signal plots (which determine that) are exceptionally clean. We've always known Medusa to be a sector capacity leader, but the lower cost of LTE UEs makes it potentially cost-effective too, compared to using proprietary 450-family SMs. So while I haven't seen Cambium announce the product (they have talked about it coming this year), it sounds like it's right around the corner. Which could put some "alternative" purchases on hold, if the timing is right. So I have a few questions.
- When will it ship?
- Will it cost more than the proprietary Medusa?
- The FCC approval names 5, 20, and 40 MHz channels. Are 10 and 30 also supported? CBRS is based around 10 MHz channels so that would be very useful.
- Is this going to work by itself, like any other PMP, or will it emulate mobile LTE eNBs and require a Core?
- Will LTE work under Part 90 rules too, prior to moving onto CBRS?
Thanks!
