Wireless can give you gigabit speed with sub 10ms latency, for sure! With a few assumptions and caveats. You have to work out a compromise involving spectrum width, power usage, transceiver positions, etc. etc. etc. to get optimal performance, for all the various definitions of optimal.
And there are lots of games you can play with QAM, channel-hopping, frequency division, and I am sure that future DSP experts will invent still more ways of getting more data to more people faster with less power. But the basic compromises still need to be dealt with. Using a wired link, you can blast data as fast as you want to yourself without messing with other people, on wireless things are more complicated.
But enough of that, to answer your question: here's a product that can get you 20 Gbps and 0.2 ms latency over hundreds of kilometers:

Easy as that! ...but you're not about to mount one of those on your cell phone.
In an ideal world, all wireless access points could adjust their configurations as required. They'd share information on their physical locations, transceiver capabilities, power status, and bandwidth usage, with the data flowing across the landscape like electrical current in a sheet of metal or water in the shallow riffle of a stream. And of course all these devices would contain unimaginably brilliant and complex software that would manage all this with high efficiency, and they'd all interoperate seamlessly. And since this is the ideal world, no one would ever use the transceiver information from the network for nefarious purposes, and we'd all share the burden of keeping adequate transceiver power available, and the power would be generated from renewable energy sources.
But that ideal wireless world would still have far less capacity than the ideal wired world. The question is whether you think a user-driven wireless setup can be superior to the crappy wired situation we have now.
