Microwave Comms Betwen Population Centers Could Be Key To Easing Internet Bottlenecks

itwbennett writes: Researchers from the University of Illinois at Urbana-Champaign and Duke University recently looked at the main causes of Internet latency and what it would take to achieve speed-of-light performance. The first part of the paper, titled Towards a Speed of Light Internet, is devoted to finding out where the slowdowns are coming from. They found that the bulk of the delay comes from the latency of the underlying infrastructure, which works in a multiplicative way by affecting each step in the request. The second part of the paper proposes what turns out to be a relatively cheap and potentially doable solution to bring Internet speeds close to the speed of light for the vast majority of us. The authors propose creating a network that would connect major population centers using microwave networks.

      There are so many ways that could be abused though - both by the ISPs and the end users.

      Game server too laggy? Switch it to port 443 UDP - ISPs will think it's Skype voice and give it top priority.

      There is a really simple solution to this. Allow users to set their own QoS rules, and the ISPs respect them, and can charge a different rate for different levels of service.

      So, if you just want your SYNs prioritized it isn't a problem, and it probably won't cost you much. If you want your bittorrent traffic prioritized, that also isn't a problem, and it will cost you a fortune.

      If everybody tried to ship all their mail/etc FedEx priority overnight FedEx would grind to a halt for months until they scaled up. It isn't a problem, and there are no limitations on what can be sent priority overnight, but people regulate themselves because most will not pay $70 to ship something when the $7 service that takes 2 days longer is good enough.

    Microwave networks are extremely susceptible to rain fade, and as such are not a good choice for important data links like these would be. We already have a technology which allows signals to travel at the speed of light and is immune to weather, solar radiation, and nearly anything else short of a major earthquake. It's called single mode fiber optic cable.

    I didn't know a hung-over backhoe operator was considered in the same class as a major earthquake.

  10. I had microwave Internet 15 years ago... by rockmuelle · · Score: 3, Informative

    In Lousiville, CO, I lived in one of the few neighborhoods that was skipped over for broadband in 1999. Sprint setup a microwave service that filled in the gap. Bandwidth was awesome - I was getting 10-30 MBs regularly. The downside was the latency - 100 ms ping times were the norm. I remember trying to play Duke Nuke 'Em with friends and having the unfair "advantage" of disappearing regularly when my client didn't ping back in time. Being line-of-site, there were also issues with trees occasionally swaying in front of the dish (a pizza box attached to my roof) and snow blocking the signal.

    As others have pointed out, microwave Internet isn't something new and, unfortunately, in the real world isn't a perfect solution.

    Buffering and switching latency is the main source of delay, not signal latency in the copper and fiber. Microwaves would do exactly nothing to improve the switching and buffering latency. If anything they'd make it worse: light in fiber travels much further than line-of-sight microwave before it has to be regenerated with another delay.

    Verizon is the result of the merger of Bell Atlantic (who had also bought NYNEX (another Baby Bell)) and GTE. Verizon bought MCI Worldcom in 2005, which became Verizon's business division (and is also known now as "Verizon Business").
