At the moment.
- venomsnake 10y agoLaws of physics tend to change infrequently. Sharing spectrum means low speed for all.
- lisivka 10y agoSo beams must be directional, to avoid sharing of spectrum with all, but only with some.
- cyphar 10y agoThe problem is that broadcasts are exactly that: broadcasting. They transmit in all directions. While you have bandwidth constraints in wires, they're all localised to the wire. Even parabolic dishes (which make getting a signal a huge PITA) still aren't as localised as cables. Wired connections get a bad rap, but they're actually a much more preferable (and scalable) medium for transmission than radio waves. Not to mention that "bidirectional beams" is another way of saying "noise".
- dmm 10y agoA fiber of glass is the ultimate directional antenna.
- mikecb 10y agoI'm not suggesting that, but that economics changes things much more rapidly, c.f. 5G, which may roll out multi-gigabit speeds to consumers far before landline.
- venomsnake 10y agoAnd how you will provide multi gigabit speeds to a 100 people in close proximity simultaneously? There is the question of throughput of the whole network.
