Wired Towns builds high performance public Wi-Fi Hot Zones. Our gear of choice comes from Altai Technologies, a Hong Kong-based company that is otherwise in 50 countries around the world. They are barely known in the United States, but Wired Towns is doing everything it can to change that.
We deployed Altai in Times Square for Yahoo! and in Union Square and Rockefeller Center as well. We brought Altai to Lemcon Networks, our wireless network integrator partner, and had Lemcon become both a distributor and an integrator of Altai.
Altai may not always be the best choice in Wi-Fi networking solutions, but for the past four years they have been — better than Cisco, Ruckus, Belair. Altai’s solution is superior because they alone have solved a basic problem that plagues all Wi-Fi networks — the fact that the radios on your device — on your iPhone, your Blackberry, your Nexus One, your netbook or laptop — is low powered. An access point may be able to broadcast out to a device, but can a device communicate back, especially in noisy urban environments where there is a lot of interference?
Every time we have deployed Altai, we have seen our traffic and our footprint increase between 5X-10X. That leap in performance for us makes public Wi-Fi possible, makes it cost effective.
Faced with this basic limitation in device radios, people have been building networks that have a high density of smaller access points, often in a mesh topology. The current standard is to have 60 access points per square mile for adequate coverage; ideally no device would be further than several hundred feet from an access point.
But now to achieve adequate coverage, you have also acquired some real problems:
You have to acquire 60 sites per square mile. If for instance you are mounting on lightpoles, that can get very expensive in a hurry.
You have to provide each site with electricity.
You need to get bandwidth to each node. You can either connect each node to the internet — impractical — or build wireless bridges between nodes, such is in a mesh topology, a solution that has a lot of network overhead and capacity issues associated with it.
You have to manage a network with a lot of nodes. The network, though ideally redundant and self-healing, has a lot of complexity associated with it.
You have to maintain a network with a lot of nodes. There’s a lot of hardware that can be unplugged, that can break. That’s costly to support.
The Altai solution is unique: Rather than requiring 60 access points per square mile, you can build one central wireless hub — preferably on high ground on a library, a church, a community center — and use that to provide community wireless for a town. 3-4 Altai A8Es Altai A8-E Catalog (Eng) 091014.pdf($8000 list price), each covering 100 degrees, can reach out 1500 feet from that central hub. From there Altai’s C1 repeaters Altai C1 Catalog (Eng) 100105.pdf($168 retail) can connect to the A8E from up to a mile away line of sight in an urban environment, and up to two miles in a rural one. If you pair two C1s, you can make a new hot spot from that.
Let’s say you had 4 A8Es on your hub. You could easily support 25 small Hot Spots per A8E using 50 C1s paired together.. There would be the main footprint — a circle of 1500 foot radius, then the extended footprint with a radius of 1-2 miles filled with 100 smaller Hot Spots deployed where needed.

With the C1s, there is no need for the end user — a home or small business — having to worry about configuration. Just point it toward the access point and plug it in. In terms of maintenance and network management, you really need to concern yourself with just the four A8Es on your rooftop hub.
Right now this solution is being deployed by China Telecom on a very large scale. It is easy to deploy, cheap to maintain, and as it is ‘hub and spoke’ is able to deliver a much faster more reliable experience to users. You are always one hop from the internet. That means more bandwidth, better video, better VOIP.
Wired Towns is actively seeking the opportunity to deploy a large scale Altai solution in a major city. After deploying in Times Square, Union Square and elsewhere with Altai, we are ready, with our partner Lemcon, to build something much larger that will outperform any public Wi-Fi network in the U.S. The fact is, Altai is just breaking into this market, and right now no one can match their performance.
