No, but you can work within it's limits to achieve some fairly spectacular things.
I predict that if low-orbit sat service starts bringing competition to rural areas, we will see the cell companies start using spatial diversity antennae to dramatically up the available bandwidth.
- vvanders 7y agoI'm not sure how solving problems with multi-path and/or LOS helps here. The fundamental problem with rural is that the $ invested : customers served($ out) is drastically lower as population density diminishes.
- grandinj 7y agoSpatial diversity does more than help with multi-path issues. It multiplies your available bandwidth by sub-dividing the space around the base-station.
- vvanders 7y agoBandwidth doesn't help you with HAAT[1] and the fact that you need to build out towers every couple miles or more depending on your terrain. Towers are not cheap to build or maintain, if you only get a couple hundred people per tower it may not make sense to do(and why you don't see a lot of community WISPs except in unique cases).
