Thinkpad It is early days, but this is a growing business, says Mark Whitton, general manager of Nortels wireless Lan (local area network) operations. Ron Sege, chief executive of California-based Tropos Networks, the leading Wi-Fi mesh network infrastructure provider, agrees. Our business is growing quickly across the board, he says.
The latest free broadband offer from Sky will usher in a new era for broadband, according to price comparison website uSwitch.com.
Microsoft Tropos is one of a handful of private startups that have pioneered the emerging market for Wi-Fi mesh systems. These new large scale Wi-Fi mesh networks - dubbed muni, metro or urban networks - are another factor helping to reshape the worlds telecommunications markets. Proponents argue that in many situations where it is difficult or impossible to rollout hard wired broadband networks, the economics of Wi-Fi mesh networks are compelling.

Laptop Computers In the US, nearly 50 municipalities were already offering metro-scale broadband wireless by last autumn and the number is growing rapidly. According to some estimates, up to 750 towns and cities across the US plan to provide their citizens with wireless broadband access by the end of next year.
We are starting to stock a lot of wireless broadband equipment. Wireless broadband is becoming ever more popular with computer users. Whether it be to connect to your broadband connection or from one computer, laptop or notebook to another computer, laptop or notebook without having wires all over your house or, maybe, wireless networking is the logical step. With the new generation of voice over IP phones coming out we are starting to stock wireless phones. These allow you to use your computer to make cheap phone calls all over the world, usually for less than the price of a local call.

Laptop Computer Many of these towns and cities are deploying municipal Wi-Fi mesh networks in order to provide their citizens with reliable, low cost broadband access, others like San Mateo in California and Oklahoma City have deployed networks in order to improve communications for emergency service crews.

Desktop Computer Where Wi-Fi mesh networks have already been deployed, subscriber take-up rates have generally exceeded expectations and most city managers report they are pleased with the results.
Notebooks While most early deployments have been in relatively small towns such as Chaska, a small town south of Minneapolis with a population of just 18,000 (see story below), the latest batch of cities to announce plans to deploy Wi-Fi mesh networks include giants such as New York, Boston and Chicago.
Lenovo Almost without exception, proponents of muni Wi-Fi mesh networks see them as complementing rather than replacing traditional communications technologies.
Hard Drive They have however, met with fierce resistance in some US markets from established mobile carriers. In Philadelphia, for example, the citys plans to spend $10m rolling out a Wi-Fi mesh network to cover a 135-square mile area have been roundly condemned by Verizon Communications, the nations biggest telecommunications group.
Travelstar Concerned about the potential impact on their broadband operations, the telecommunications and cable industries helped push through a Pennsylvania state law late last year that could prevent cities in the state deploying their own high-speed networks. The bill, which specifically exempted Philadelphia, has prompted similar legislation in at least 11 other states.
Gateway These bills have outraged municipal Wi-Fi proponents, who argue that cities must retain the right to enter the market in order to ensure ubiquitous cheap broadband access for their citizens. At a time when US regulators and legislators are growing increasingly concerned that the US could be falling behind Asia and Europe in broadband penetration, analysts suggest it is unlikely that Washington will intervene to stop cities such as Philadelphia providing alternative, affordable broadband.
Laptop Parts While cable and DSL providers typically charge between $30 and $45 a month for broadband access, Philadelphia is expected to charge subscribers $20 a month or less. Outside the US, big cities ranging from Taipei, Taiwans capital, to Amsterdam have announced ambitious plans to build extensive Wi-Fi mesh networks and many other cities are building extended Wi-Fi hot zones blanketing downtown areas or business districts with Wi-Fi radio coverage.
Software Taipeis $70m project to build what could become the worlds largest Wi-Fi mesh network is perhaps the most ambitious incorporating about 10,000 wireless access points and covering an area of about 272 square kilometers where 90 per cent of the citys 2.65m population lives.

In Britain, Ontario-based BelAir Networks, another municipal Wi-Fi mesh network pioneer, and Citispace, the leading UK-based provider of urban digital networks, recently completed the Technology Mile - an unbroken wireless hot zone spanning the London Borough of Islington.
Hard Drives IDC, the market research firm, argued in a recent report on mesh networking in Western Europe that wireless mesh networking will be, the next step in Wi-Fi development. The research firm noted that, because mesh networks are quick and easy to deploy and, more importantly, significantly reduce the need for wiring the backbone, wireless mesh architectures can have a positive impact on extending the reach of Wi-Fi zones.
Electronics However IDC also added that while there are already a number of wireless mesh deployments in the US, European interest in mesh topology for creating large wireless networks has just started to take off and most deployments are still in their early stages. In Europe, where Alcatel, the French telecommunications equipment group has formed a partnership with BelAir, Wi-Fi mesh networking is currently mainly used in metropolitan areas where it serves as either an alternative for broadband services to end users or is used to create local government networks. Only four of the existing mesh networks in Europe provide public wireless access services.
Canon Meanwhile although IDC says established hotspot providers have yet to announce publicly the usage of mesh for creating large-scale hot-spots, it is likely that operators have already started to look at this option.
Desktop Pc Wireless mesh architectures are also useful for large enterprises, corporate or academic campuses. In areas that are more difficult to wire, mesh provides advantages in extending wireless coverage, says Martine Lapeer, chief technology officer of Alcatels Mobile Communications division. It is a good niche product, she says but agrees with others that it is not a serious rival to cellular networks, not least because voice over Wi-Fi is unlikely to be able to offer the same quality of service guarantees.
Desktop Computers Over time, mesh nodes will be integrated within the wired as well as traditional Wi-Fi networks, predicts IDC. Nortel for example, has already positioned mesh as an extension to its existing W-Lan (Wireless Local Area Network) product portfolio. In addition, switch vendor Trapeze Networks has revealed plans to use its management system for integrating mesh solutions into traditional W-Lan and Lan networks. To date the market for Wi-Fi mesh network infrastructure has been dominated by a handful of startups including Tropos, BelAir and California-based Fireside.
Think Pad Other companies including Pronto Networks provide gateway and service software for Wi-Fi systems. Although wireless mesh is now mainly offered by start-up companies, IDC expects established network vendors to follow Nortel and Motorola and announce their own mesh solutions, or co-operate with one of the mesh start-ups in the near future.
Repair Meanwhile, other companies such as Santa Clara-based Azaire Networks make it easier for mobile operators to deploy converged networks combining multiple IP access technologies. Hybrid networks combining technologies including Wi-Fi and cellular are the way forward, says Bill Howe, Azaires chief executive.
Data Recovery He believes that the market will eventually evolve to the point where the most appropriate radio technology will be used for the task at hand and points to the emergence of dual-mode Wi-Fi/Cellular handsets as evidence of this trend.
Cisco Over time, mesh networks will be integrated with wired as well as traditional Wi-Fi networks, argued the IDC report. In the meantime, interest is growing in the next member of the wireless radio standard family - WiMax, the emerging wireless technology that aims to deliver broadband connectivity over large geographic areas.
Keyboard Initially most experts believe WiMax will be used to provide high capacity backhaul services to Wi-Fi hotspots and mesh networks. But most Wi-Fi mesh network infrastructure vendors are preparing to offer WiMax as an alternative mesh radio carrier - a move that could eventually drive down the cost of mesh networking while extending both their range and capacity.
