The balance of wired and wireless

Recently I installed a 4G LTE router in a site where there is a poor wired Internet service with no plans for improvement, but a choice of proximate 4G LTE base stations. The resulting wireless throughput is better, the service more reliable, and the prospect of further improvements immanent – partly because of the increasing competition between the wireless Internet service providers (WISPs) offering 4G. Apparently the wired infrastructure is not economically viable to upgrade according to its ISP. This is surprising statement given that the area is very densely populated with consumers and wired infrastructure. Perhaps what they mean is not enough disgruntled customers are leaving for 4G to justify spend on upgrading their service yet. This is not the first area I have come across with that attitude by an ISP. The first time I was told this was also in a build-up area, but it had fewer consumers and more businesses that are probably paying for leased lines anyway, so it was easier to see why there. Anyway, this attitude made me wonder where it is economically viable to put in at least fibre to the cabinet. Obviously the WISP base stations that serve this recent site need to aggregate a lot of data, and at least one of them has no wireless carrier antennas, so I suspect it is using fibre for backhaul. I think this is a case where wired infrastructure can more easily make money. It has the throughput advantage (at the moment) that can justify the cost of digging in a heavily developed area with strong property laws. I expect ISPs to continue to cede customers to WISPs and wired infrastructure to further retrench and focus on highly aggregated throughput.

Now suppose that some clever researcher finds some scrap of information intrinsic in electromagnetic radiation that allows distinct transceivers to be identified, or even just groups of them. This would make a dramatic difference to wireless communication because spectrum becomes less contended. In fact something like that has already been announced in the shape of pCells. I hope for and expect more innovations of this kind. When they arrive they will have a profound effect on wireless communication and wires will retrench further.
