Public Access Wireless Program

Fourteen years and four program names — JaxWiz, municipal Wi-Fi, public wireless, Downtown Wi-Fi — from inheriting somebody else's pilot to a signed, mapped downtown build still being extended four years later.

It began in 2005 not with a deployment but with a site survey and an equipment list, for a public-access network the city was taking over rather than building. Inherited DSL circuits were consolidated site by site onto a single city account — which is the unglamorous thing that turns somebody else’s pilot into a supported service.

Network analysts ran the sites and the circuits; the architecture and the evaluations sat here.

The measure of whether it had actually become a service is mundane and decisive. The downtown Landing node sat in the monitoring platform under its own name, and an outage there opened a severity ticket with an assigned engineer and a scheduled update, the same as any other government system. A pilot nobody is paged for is still a pilot.

Arrays rather than access points, and eight years of standing by it

The decision that shaped the rest was made in 2007, on demonstration units, against the design question that actually matters outdoors: a plaza or a street is not a building. Blanketing open ground with individual access points produces interference and cost rather than coverage, because there are no walls to contain a cell and every radio hears every other one.

Multi-radio arrays answered that, and the same architecture came back weatherized in 2015 for the outdoor build — eight-radio arrays at the central plaza, further arrays at downtown intersections, on city fiber with cellular backup, installed under a festival deadline with Traffic Engineering.

Two things made that a city asset rather than an event build: the equipment stayed afterwards, and Traffic Engineering was reimbursed for the overtime out of the project rather than absorbing it. A department that pays for someone else’s deadline out of its own budget declines the next one.

Technical and political evaluation at the same time

Which is usually the only way either finishes. While the array testing was live, a municipal wireless briefing went to a sitting City Council member; in parallel, a technical planning session with Cisco on the digital divide was run as a propagation and geographic analysis rather than a policy workshop, with RF coverage prediction over the city’s own GIS data before any siting decision.

The city’s Public Information Officer was in that first session deliberately. A public-access network is a communications program as much as an engineering one, and the recap should not be written after the design is fixed.

The downtown build

Availability written so it could be enforced

The service level agreement construction adopted in July 2014 set system availability at 99.99 percent a year. Anyone can write that number; the work was in the three clauses that make it mean something.

Complete outage was defined as twenty-five percent or more of access points from the wireless edge failing to provide at least half of the designed service capacity per access point — which binds the figure to a measurable degradation threshold instead of to an argument after the fact. A scoped exclusion schedule established what the number was a number about: customer-caused faults, customer-provided power and facilities, denial of site access, scheduled and emergency maintenance, force majeure. And the construction obliged the statement of work to specify users per radio and bandwidth per radio, so that “designed service capacity” had a defined value to measure against.

Without that last step the clause is unenforceable in both directions, which is the usual state of availability language in public contracts.

Carried to a signed, mapped, thirteen-revision delivery with the Downtown Investment Authority — architect alongside the authority’s lead and a project manager who ran the schedule.

The engineering was the tractable part. Two of the structures needed for coverage belonged to other public bodies, the library and the transit authority, so those points had to be negotiated into executed agreements rather than designed around.

It signed off in January 2017, and the deployment map was still being reissued in 2019 as further arrays went up for a downtown festival — which is the test a pilot rarely passes. It was still being extended four years later, by people who had not built it.

Outcome

A public-access network that became a supported city service, signed off in January 2017 and still being extended in 2019 by people who had not built it.
