If one user draws 5 Mb continually then only 15 Mb remain to be shared with and between all the remaining customers. If a second user now draws 5 Mb continually then only 10 Mb remains to be shared by all the other customers. If four customers are each drawing 5 Mb continually then there is NO remaining throughput for any of the remaining customers. Mike Hammett wrote: I do understand how it works.

Because an AP can deliver "x" amount of throughput during a speed test between two location does not mean that the same AP can deliver that amount of throughput to all the customers simultaneously. The AP's throughput is shared between all of the end-users. When the AP maxes out, some (possibly all) of those end-users must slow down. Some WISPs do not understand this and thus they end up over-promising throughput and disappointing their customers. WISPs need to understand this or they will fail in this business and give other WISPs a black eye in the process. Nobody is getting beat up here; this has nothing to do with personalities. It has everything to do with the physics of data communications behavior. Everybody needs to understand the true limits of their system. Why is this? Because the "air" is a shared medium. Throughput delivery takes real-world time in intervals we call "time-slots". You can only carry so much throughput during one time-slot. There area only so many time-slots (fractions of a second) in each second. This is why throughput is limited. Only so many users can be on one AP at the same time if they are requesting a large amount of the available AP throughput. A lightly-loaded system may appear to be able to deliver max throughput simultaneously to those few customers but when the AP is heavily loaded with users who are vying for a lot of throughput simultaneously then most of them will need to slow down because not everyone will get all the time slots they need to carry the high throughput (ex: video streaming) levels that they are requesting. Don't make this personal; that simply detracts from the very real technical limits that a successful WISP must understand in order to succeed and survive. jack Mike Hammett wrote: I didn't get that at all. It seems as though when anyone on this list suggests going faster than 2 megabits, they get beat up.

Yesterday, representatives from technology and telecommunications companies, labor unions and public interest groups frequently at odds with one another agreed to provide the next president with a roadmap for how to accomplish those goals. That map could include tax breaks, low-interest loans, subsidies and public-private partnerships to encourage more investments in upgrading and building out high-speed networks, representatives from Google, AT&T and public interest group Free Press said during a panel discussion on broadband policy that also served as a coming-out party for their newly formed coalition. The details of how to meet those goals still must be worked out by the group, whose aim is to bring more affordable high-speed Internet access to every consumer. Many of the group members have been at odds with each other on whether the government should set limits on how much spectrum a company can hold, the use of unlicensed devices on fallow broadcast airwaves and net neutrality -- the notion that network operators should be prevented from blocking or slowing Internet traffic. The formation of the group is an effort to move beyond their differences. "The coalition is a positive in that it demonstrates we agree that we have a broadband problem, which not everyone was willing to admit to two years ago," said Ben Scott, policy director at Free Press and a member of the group. "The key is whether we'll see this group produce policy solutions that will require difficult choices." At stake is the nation's ability to compete technologically and economically, the group said. The United States has dropped from the top 10 nations for broadband access, speeds and price in the last several years. The coalition is pushing for a federal plan that would provide access to high-speed Internet service, much as the government did with electricity, roads and phone service. Obama famously used the Internet for outreach during his campaign and received 370,000 donations online. He's proposed using blogs, social networking tools and community Web pages known as wikis to connect citizens to government agencies. And Obama has argued for massive upgrades to technology infrastructure such as high-speed, or broadband, Internet. So far the coalition's plans to increase broadband usage mirrors Obama's plan, but there could be disagreement over deployment, analysts said. Communications Workers of America President Larry Cohen said the union supports a proposal by Sen. John D. Rockefeller IV (D-W.Va.) to increase definitions for broadband to 10 megabits per second for downloads by 2010. The current definition for broadband speed in the United States is 768 kilobits per second downstream, which is far below standards in many other nations. Achieving that goal at prices acceptable to consumers, however, would be expensive for telecom and cable network operators. Some in the coalition could push for laws that would achieve lower prices and higher speeds through more wireless and telecom competitors, but that could cause further disagreement among members, Scott said. Some have already suggested requesting funds from the federal economic stimulus plan for broadband deployment. Yesterday, an aide to House Speaker Nancy Pelosi (D-Calif.) said Pelosi was in favor of that idea. AT&T chief lobbyist Jim Cicconi said the company has moved closer to the view of public interest groups and Google that the Web should be open for all users without discrimination of technology and content on their network. But unlike Free Press and consumer groups, AT&T opposes new laws or rules on net neutrality, saying Federal Communications Commission rules are sufficient, and any violation should be handled on a case-by-case basis. "There will be significant outstanding debates that will be very tough and there will still be daylight between the groups on many, many issues," said Rebecca Arbogast, an analyst at investment firm Stifel Nicolaus. "But both sides are in a phase right now where they are emphasizing how much they share in terms of their views on what is an appropriate framework for looking at this issue."
