This is going to be a mess to slog through over the next 15 years until wireless speeds (and costs) leapfrog hardlines completely.

- xcrunner529 13y agoI've seen articles that it is just not feasible or even possibly to put all of the burden the wired networks carry onto the wireless ones. Besides the ugly data caps we have to deal with there, there's not enough room in the frequencies. Wireless is used as an excuse to not put in effort with wired and it's going to screw us.
- amirhirsch 13y agoThere's plenty of room in the frequencies, even just using linear momentum encoding with directional transceivers. Add in MIMO/OAM and and suddenly there's even more bandwidth. the FCC / ownership of spectrum is a whole other chimera. Wireless today is like using a LED and a photodiode instead of a screen and a camera.
- zw123456 13y agoI think you mean OFDMA/MIMO, which is what LTE uses.
- zw123456 13y agoI should have Googled before I spoke, Orbital Angular Momentum, very interesting... http://lup.lub.lu.se/luur/download?func=downloadFile&recordOId=2062936&fileOId=2339120 http://lup.lub.lu.se/luur/download?func=downloadFile&recordO...
- amirhirsch 13y agoThere's some debate about whether OAM demonstrations are just MIMO, and some suggestions that the eigenmodes are equivalent. Either way, there will be regulatory hurdles to more efficiently using the spectrum. I like the perspective put forward in this post: http://www.reed.com/blog-dpr/?page_id=117 http://www.reed.com/blog-dpr/?page_id=117
- bicknergseng 13y agoI've been wondering for a while why this doesn't get brought up more whenever spectrum debates happen. I expect some amount of it chalked up to crappy fact reporting and lazy business attitudes, but you would think someone on CNN or the NYT could do 15 minutes of googling and actually bring some sense to the table...
