Speeds are reduced to the point of in-operability without line of sight (latency also goes upThat's likely an issue where I am. Even with a 50ft mast, I doubt we could achieve LoS as the xceiver site is 'over the hill and far away'. Would be rather unstable too, without tethering.without line of sight). It's also TDD, which means that if you have 10 customers within the same 10 radial degrees of the transmitter then they have toLess of a problem; a largely elderly, conservative (technologically speaking), rural, population likely means a fairly low take up. That said, there seems to have been enough interest for Airband to consider the area. A single Wimax mast can have a range of a radius of around 50miles. Let's say that they manage to find backhaul at their mast location of 1Gbps. The 10 degree slice we are talking about is a triangle with a point at the mast stretching out for 50 miles, with the far width of the triangle about 8.5 miles in length. All users who fall into that 10 degree slice have to share, at best, 27Mbps (1/36th of the 1Gbps backhaul) amongst themselves, and this will degrade with anything that causes radio interference, weather, non-line of sight etc... Unfortunately that degradation can be pretty steep with WiMax. Of course, I'm still just conjecturing that: 1. It is WiMax underlying technology |
