Do Mesh Networks Scale? Two Views

Do Mesh Networks Scale? Two Views 07/06/2004 03:22 PM
The head of a mesh company argues mesh networks don't scale -- and one of the folks behind an open-source mesh software project examines the argument: MeshDynamics sells a multiple-radio solution for mesh networking, and the head of the firm wrote a brief article explaining why single-radio mesh networks can't work beyond a very small deployment. I asked Sascha Meinrath of the CUWiN project for his feedback on Francis daCosta's comments. Sascha writes: While I do think that Francis daCosta brings up some potential pitfalls to wireless mesh networks, the doomsday picture he presents is based on a flawed understanding of how mesh networking topographies work. I'll explain below: deCosta wrote: 1- Radio is a shared medium and forces everyone to stay silent while one person holds the stage. Wired networks, on the other hand, can and do hold multiple simultaneous conversations. 2- In a single radio ad hoc mesh network, the best you can do is (1/2)^^n at each hop. So in a multi hop mesh network, the Max available bandwidth available to you degrades at the rate of 1/2, 1/4, 1/8. By the time you are 4 hops away the max you can get is 1/16 of the total available bandwidth. This problem exists only when all tranceivers within a mesh topography "see" each other. And herein is the flaw in the argument. Within a mesh network Request To Sends (RTSs) do silence nodes within range; however this degradation moves in waves--so if part of a mesh consisted of 7 nodes (of which G is connected to the Internet): A-----------------> ------B-----------------> ------------C-----------------> | Internet Connection Here's what would happen. A would pass a packet to B; when B passed a packet to C, A couldn't talk--thus the 1/2 reduction in throughput; when C passed it to D, the same problem would occur for both A & B (thus a 1/4 throughput); likewise for D to E (because D would silence A, B, & C), thus a 1/8th throughput. However, when E passes a packet to F, A is unaffected, when F passes a packet to G, both A & B are unaffected. Thus, in this solution, throughput would theoretically max out at 1/8th (which is probably still much more throughput than the average Internet connection--where the usual bottleneck resides). What this really points to is the need for power control in radios (which is something that CUWiN wants...

Another Billion into Networks, as Sprint
PCS Heads for 3G; Cingular Makes Plans,

Another Billion into Networks, as Sprint
PCS Heads for 3G; Cingular Makes Plans,
Too 06/22/2004 10:34 AM
Sprint PCS joins the third-generation cellular rush in the U.S. by committing a billion dollars to building a 1xEV-DO network: The company had previously signaled its interest in waiting and then deploying an EVDV (data/voice) network that might have had higher download speeds and integrated voice into the same 3G footprint. Now they say that some markets will have their brand of service year's end with many more in 2005. Cingular, meanwhile said today that UMTS could appear as soon as next year. Cingular had recently expressed doubts that with the current available spectrum they could deploy 3G data networks before 2006. Now, they plan a trial of two kinds of UTMS: one operates at 384 Kbps (unclear if this is the rated speed or the typical speed), and another at up to 14.4 Mbps. That's megabits per second. Trials will start in Atlanta this summer, and extend in 2005 to the rest of the country. AT&T Wireless, which Cingular is in the middle of acquiring, has reiterated its plans in the last few months to try UMTS's W-CDMA flavor in a few cities by the end of 2004. T-Mobile's plans are obscure, but EDGE (2.5G/100 Kbps) should be on its way. Nextel will most likely pursue a private cell data plan with higher speeds but that use none of the popular flavors. Suddenly, some towns with no-better-than-modem wireless speeds could have four competing cellular data networks with 100 to 400 Kbps average download speeds. (All of these flavors ostensibly have restricted uploads of about 50 Kbps, however.) Expect price competition. At $80 per month flat for Verizon Wireless's high-speed network, the race to the bottom will start in earnest. Verizon Wireless will still likely have a leg up by offering service first in most competitive cities....

The technology is designed to allow users to access a network from farther away from an AP. It looks like PacketHop is announcing that it acquired some patents from SRI International which has already done some development of a product. It's not clear when this product will be available. (FireTide has also licensed SRI patents for its products, which include a few mesh-like attributes.)...

Titanium Mesh Titties

Titanium Mesh Titties 07/01/2004 10:48 AM

While metallic pleasure bots are high, high up on the lists of gadgets we'd like to see in the near future, we're not so sure that implanting titanium mesh under the breasts of women is the way to get the party started. Nein, der boobenkreiger ist gut, says Dr. Ziya Saylan, a German doctor who has developed the technique that over two dozen women have already tried. The idea is that the titanium will hold up the huge breast implants, preventing the sagging that many older women are getting implants to correct in the first place. If anyone has a picture of the implants, we'd love to see them (outside of the breasts, if you please).
Read - What a lovely pair of titaniums! [IOL]

Update: Reader Stoffel Van Eeckhoudt sent this link to the home page of the procedure that has ample pictures of both the mesh and of women's breasts both before and after the procedure. It's NSFW, unless you work in a country where the sight of womens' jububbles doesn't cause enduring national scandal.

How Many Social Networks Is Too Many?

How Many Social Networks Is Too Many? 11/14/2003 02:29 AM
I keep reading about all these "social networking software" plays, and the amazing thing to me is that, unlike during the last bubble, everyone except people working for these companies or venture capitalists seem to know it's a bubble. Yet, they keep on coming. The latest is that Evite has launched their own version of Friendster tied to their event organizing system, and eMode (known for their fun tests and dating system) has changed their name to Tickle, which is what their Friendster wannabe is called. They also bought another social networking service, to take one of about 100 off the market. Who the hell signs up for all of these systems? Paten ts aside, there is nothing complicated in creating such a site (there's even one Friendster rip off called Yet Another Friendster Rip Off). The complication comes in actually making money from such a site. The odd thing, though, is the rampant skepticism about these sites. In the 90s bubble years, it was never like this. Sure, there was some skepticism, but not the near universal skepticism that is focused on social software space right now. What's funny is that you would think so much skepticism would make the VCs stay away, but the reverse is happening.

If more airlines start doing this, it will be interesting to watch what happens to the companies that are already offering fee-based services in airports. That seems to be a big business, with hotspot providers signing exclusive deals with airports. I wonder what sort of rights airlines have to build Wi-Fi networks in the gates they often use. Glenn has heard from some folks in the industry that airports are starting to assert rights to spectrum that they previously left alone, or encoding these rights in new contracts as airline leases expire....

How to Pay for Municipal Networks

How to Pay for Municipal Networks 09/21/2004 02:46 PM
Some municipalities may have already learned some lessons about offering telecom services that they can consider when deciding to build Wi-Fi networks: Some of the most successful municipal offerings of wired telecom services started out with small trial networks and were offered by municipalities that already offer utility services to customers. But beyond whether a municipality has experience with billing and marketing a service, Wi-Fi presents a bunch of additional uncertainties. In the wired example, in many cases the market doesn't have any other option for broadband Internet access and customers definitely pay for the access. In the case of Wi-Fi, in many cases other service providers may already offer wireless access. Plus, cities have to decide whether they want to offer access for free or for a fee. If they want to deliver free networks, they have to decide how to fund it, considering both the initial outlay and ongoing support costs. Ultimately, citizens of communities may end up deciding. In St. Cloud, Fla., the city is trying to decide how to pay for the ongoing maintenance of the network and will likely ask residents to decide on a ballot referendum. If municipalities decide to ask residents to pay for access, they have to hope they can cover their costs. At this stage in the market, based on the experiences of commercial Wi-Fi providers, it's not clear that an operator can make money from for-fee networks....
