Then why did we have 900 MHz analog cordless phones in the 1990s?
- vel0city 6y agoIt's not necessarily a limitation of bandwidth possible at 900MHz, it's a limitation of the normal equipment deployed and inefficiencies of mesh routing. Those 900MHz analog phones were also usually low power, low distance, analog only devices with a few number of channels. Try having dozens of those phones all in the same room and see how useful they all are at once.
- kumarvvr 6y agoIn that case, the spectrum was used as a replacement for the cable, in a 2 point system. A mesh network is a completely different beast, with perhaps hundreds of thousands of nodes, spread around, and a good chuck of bandwidth being used for forwarding data between nodes.
