High-speed Internet connectivity still is an elusive
luxury for most Indians: with just over a million
broadband subscribers in a country of more than one
billion people, only the best off in the big cities can
take advantage of it. But WiMax, the IEEE standard for
wide area wireless broadband connectivity, could be
coming to the rescue. It offers India the prospect of
largely skipping connection to the Internet by the DSL
links and cable modems that are standard in so many
other places.
“WiMax offers the best answer to last-mile broadband
connectivity in a country like India,” says Arogyaswami
Paulraj, an electrical engineering professor at Stanford
University, in California.
A number of recent developments suggest that Paulraj
may be right—or at least that a lot of corporate leaders
are thinking the same way. For example, Videsh Sanchar
Nigam Ltd. (VSNL), a leading international telecom
service provider headquartered in Mumbai, already has
deployed WiMax infrastructure in 65 Indian cities,
relying on equipment made by Aperto Networks, in
Milpitas, Calif. Aperto is a leading developer of WiMax
base stations and subscriber units built to the IEEE
802.16d standard.
Motorola, headquartered in Schaumburg, Ill., has
begun delivery of a wireless broadband system it calls
Canopy in India’s northwestern state of Rajasthan.
Motorola says that Canopy users “will be able to enjoy
WiMax benefits in the unlicensed frequency band [above 5
gigahertz] once [the system] becomes available.”
And Intel’s chief executive, Paul Otellini, made
clear during a visit to Bangalore on 23 May that
delivery of low-cost WiMax-enabling devices to
consumers is a priority for the company in India.
So far, India’s vendors and carriers have been trying
to lure customers with cut-rate service packages, offers
of low-cost personal computers, and—above all—efforts to
bring down the prices of the wireless modems and routers
needed to receive and distribute WiMax signals. “The
challenge is to devise a cost-effective solution that
delivers adequate bandwidth capabilities,” comments
Shashi Kalathil, president of broadband and retail
business at VSNL. “Of course, mobility would be a
significant added advantage,” he says.
Others are imagining the same kind of broadband
future for India. Paris-based Alcatel, having announced
it will roll out WiMax services throughout India by the
end of this year, has also initiated development of
mobile WiMax products. Last September, with the
Delhi-based Center for Development of Telematics
(C-DoT), Alcatel set up a research center in Chennai,
where the two partners will design and develop products
that will conform to the IEEE 802.16e mobile WiMax
standard.
Besides the association with C-DoT, Alcatel has a
prior alliance with Intel, for development and delivery
of WiMax equipment. These pacts might give Alcatel an
edge in a market in which it hopes to be serving 20
million to 40 million users within five years.
Smaller firms are also in the race. Beceem
Communications, cofounded by Stanford’s Paulraj, has
been a key contributor to the IEEE 802.16e standard.
Beseem, headquartered in Santa Clara, Calif., and
backed by companies like NTT DoCoMo, Samsung, and Intel,
is developing its IEEE 802.16e chip sets mainly in Bangalore.
Paulraj believes that India may be getting a jump on
the rest of the world in devising WiMax equipment and
developing markets for it.
But Indian regulators don’t seem to quite get it.
They have been slow to allocate spectrum for WiMax,
damping the technology’s prospects. Globally, bands
centered at 2.5 GHz and 3.5 GHz have been approved for
WiMax, but India’s 3.5-GHz band is locked up in defense
and space sectors. Some bands in 2.5 GHz have been
earmarked for third-generation cellphones, but they
remain unused. While there are sufficient free bands at
2.5 GHz, which could be allocated for WiMax, the telecom
regulators are dragging their feet.
“All this is hurting the operators,” says Sridhar
Pai, founder of a telecom market research firm, Tonse
Telecom, in Bangalore. “It appears Indian frequency
regulators are out of sync with global trends.” While
most equipment makers are waiting for telecom policy to
be clarified, vendors like Alcatel are pushing for a
subgigahertz band. “We will target the 700‑megahertz
band, which would be a special India [WiMax] profile,
likely to be ratified by the WiMax Forum,” says an
Alcatel spokesperson.
The WiMax Forum, based in Beaverton, Ore., is a
consortium of WiMax equipment and service providers. Its
India liaison, Sunil Kumar, says it has started
communicating with the Indian regulators directly, to
apprise them of global trends and official WiMax
positions.
Notwithstanding the uncertainties, technology
developers feel India can contribute significantly to
future versions of wireless broadband technology. “If we
can engineer wireless infrastructure—both Wi-Fi and
WiMax—to substantially augment capacity for handling
Voice over Internet Protocol, so that operators make
money on data services and offer voice calls for free,
then we’d have found the killer application for this
technology,” says Professor K.V.S. Hari of the Indian
Institute of Science, in Bangalore, a coauthor of the
IEEE 802.16e standard.
