The Wall Street Journal story is here.
As a purveyor of a WiFi Hot Spot network in 17 locations in ten NYC parks in 4 boroughs, WiFi Salon can well attest to the problem that leaves present in terms of providing reliable coverage.
In winter time coverage in Central Park at our eight locations was better than it is now. The two wireless bridges we installed in the Fall between two of our Central Park locations were shut down by the leaf heavy branches of spring and had to be repositioned.
We do very well in open fields, like Sheep Meadow and the Southern part of The Great Lawn, but have a significantly smaller coverage area around The Dairy Visitor’s Center, which is very much among the trees.
The reason leaves are a problem is because there is water in them. Likewise, heavy rains will have an effect on the signal. Of course if you are in a park in the heavy rain, you may not be opening up your laptop, or any WiFi enabled device.
So as the article details, partly because of the leaf problem, USI Wireless has had a tough go of it deploying a muniWiFi network. The Minneapolis network did, as the article omits, help to communicate details of the bridge collapse to the outside world through webcams during the time especially when the cell network was overburdened.
Tom Evslin, an expert on wireless and internet technologies, has a wonderful post on his blog Fractals of Change on what the two month old WiFi network was able to deliver as a communications system after the disaster. It says much about the value of a public WiFi network, how it can be quickly and effectively repurposed in case of disaster because it is open and not centrally managed.
Still, if you want an emergency communications system, you can’t let leaves intervene. You also don’t want spotty coverage, another problem that dogs citywide deployment plans, and which again is very much a function of the real spectrum and power limitations with WiFi.
For those contemplating or in the midst of a citywide deployment — Google, Earthlink — these performance issues undermine whatever business model may be contemplated by increasing costs in network infrastructure, by limiting service offerings, and by not meeting user expectations.
You can try every engineering trick in the book to improve coverage, quality, within the bounds set by the FCC on the 2.4GHz open spectrum, and it is amazing what can be done.
At the end of the day, though, expectations need to be reset around what WiFi does best. It is so tempting for a city to announce a MuniWiFi plan, put out an RFP. WiFi, though, should not be deployed as though it were the cell network, as though it would provide universal and mobile coverage indoors and out. If you pick your spots — where people gather, in business districts, in key municipal locations, you can put together a network of local portals that people will gravitate to when seeking to connect with their community, local government, and with localized rich media content.
Build community wells full of location specific info and services instead of trying to provide indoor plumbing to everyone. All WiFi is local.
Eric Jackson, the new CIO of Hartford cited in the WSJ article, has it right in our view:
Mr. Jackson sees the creation of a city Web portal for services and content that can be used to generate a return on their investment. ….”That’s where I think the real money is in terms of value,” he said. “It’s content, not transport.”
So yes, new models are needed, but we know what is not working now at least, and so that is causing us to function on what can be delivered, and where, and what. Keep it local, in short. As with the Internet — another open platform that fosters innovation — new uses for public WiFi will spring up spontaneously, in surprising and even lucrative ways. WiFi should be the Internet localized, a wireless intranet for a community. What will happen when the main social and economic spaces in our towns and cities are awash in wireless broadband? How will people use this ‘creative commons?’ As people begin to own and depend on their WiFi enabled devices more, the need for public WiFi will continue to grow and new revenue streams will emerge as more attention is paid to content and services, and the platform begins to be understood for what it is.
