Most schools that deploy or consider deploying wireless LAN technology, do
it to extend high-speed Internet access to classrooms. Schools in New York City,
though, are taking a slightly different approach.
The New York City Department of Education (NYCDE)
began its wireless initiative, part of the much larger Project Connect,
last year. By September 2002 it had installed wireless networks in 200 schools
-- mainly using Aironet 350 series access points from Cisco Systems. It will install an additional
300 schools by September 2003.
The difference in NYC is that the schools already have wired Ethernet drops
in the classrooms being equipped with Wi-Fi. The wireless networks were installed
not to avoid pulling cable, but to provide maximum scalability and ensure that
every student in the room could be connected to the Net at the same time.
"So if the Chancellor [the head of the department, Joel I. Klein,] decided
to give wireless devices to every child in the fourth grade tomorrow,"
says NYCDE director of information technology Joe Eaione, "we won't have
any performance problems."
How likely is it that will happen? Not very, perhaps, but Eaione points out
that the computer population in the New York school system is exploding. At
one point last year, 1,000 new computers were being turned on each week. There
are already 150,000 for 1.2 million students, a ratio of about one to eight.
"We see that [ratio] decreasing and decreasing," Eaione says. "We're
looking at using more and more wireless devices for instruction. It's one of
our big pushes. The people who are giving funding want to see computers at the
end of [network] drops. Despite the funding cuts, this is definitely still a
priroity."
The department isn't just installing one access point for every five or six
classrooms, as in most school deployments. It's installing an access point in
every classroom. Each room is its own Wi-Fi microcell.
"We wanted to ensure maximum flexibility," says Eaione.
Eaione, who taught in the New York school system himself before taking over
the IT department, and still teaches part-time at the university level, explains
the department's philosophy of supporting high-tech teaching methods to the
nth degree.
"We wanted the ability for someone to walk into a classroom and do a guest
talk or a demonstration and be able to plug in [to a wired port] -- because
they won't necessarily have a Wi-Fi card -- and the students can all be connected
at the same time."
"We don't want teachers worrying about technology. If I'm the teacher,
I want the technology to enhance me, not be an impediment. That's why we think
we need both [wired and wireless connectivity]."
The goal is eventually to equip every classroom in every school in the city
-- that's 60,000 to 70,000 rooms in over 1,200 schools. "Obviously it will
take a little while to do," Eaione says. However, virtually every school
in the system already has high-speed Internet access and most have wired Ethernet
drops in at least some classrooms.
Capital for this massive project has come in large part from the federal government
E-rate (Education Rate or Universal
Service Fund for Schools and Libraries) program. The program in effect provides
schools with deeply discounted prices on Internet and telecom services and computer
equipment.
The level of E-rate discount is based on each school's participation in free
and reduced-price lunch programs. The NYCDE has concentrated so far on schools
in the "90-percent poverty" range which qualify for the highest E-rate
discounts. In other words, the poorest schools in the city are getting wireless
classroom networks first -- a nice reversal of the usual form.
