Indians may have to wait for a few more months. While Microsoft is moving

full throttle with the planned global launch of Tablet PC at the Ambassador

Theatre in New York on November 7, 2002, a small legal issue has put on hold the

OEM’s–HP, Toshiba, and Accer–plans of a simultaneous launch in the

country.

While OEM partners of this project declined to comment on the issue citing

"non disclosure agreement" as the reason, according to a senior

Microsoft India official, the Tablet PC motherboard has an inbuilt WiFi-based

wireless LAN card– aimed at ensuring true mobility of the product–that makes

it necessary for the vendor to get Dealer’s Possession License (DPL) before

the product can be introduced in the Indian market. According to DoT norms, DPL

is mandatory for all vendors if they want to stock and trade in wireless

apparatus. While the official shrugged the matter as a non-issue and assured

that the product would definitely be out in the Indian market by December-end,

the small bit of information did raise a more serious issue. While the Federal

Communications Commission (FCC) and their counterparts across all major

countries have decided to keep the spectrum in the vicinity of 2.4 Ghz

unlicensed under the industrial, scientific and medical (ISM) band, why does

India Inc need a separate license for the use of 802.11-based products or

wireless LANs that operate in the same band?

The Wi-Fi Family
Wi-Fi (802.11) refers to a family of specifications developed for wireless LAN and specifies over-the-air interface between a client and a base station, or between clients. The specification, accepted in 1997, has several modes:
802.11: This applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS). 
802.11a: This is an extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band. It uses an orthogonal frequency division multiplexing encoding scheme rather than FHSS or DSSS. 
802.11b: Also referred to as 802.11 high rate or Wi-Fi, this is an extension to 802.11 that applies to wireless LANs and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. It uses only DSSS and is a 1999 ratification to the original 802.11 standard, allowing wireless functionality comparable to Ethernet. 
802.11g: It applies to wireless LANs and provides 20+ Mbps in the 2.4 GHz band.

The Wi-Fi factor



Short for wireless fidelity, the term WiFi has been promulgated by the

alliance of leading wireless equipment and software providers with the missions

of certifying all 802.11-based products for interoperability and promoting the

term Wi-Fi as the global brand name across all markets for any 802.11-based

wireless LAN products. While all 802.11a/b/g products are called Wi-Fi, only

products that have passed the Wi-Fi Alliance testing are allowed to refer to

their products as "Wi-Fi Certified". All "Wi-Fi Certified"

products also need to indicate the radio frequency band used–2.5GHz for

802.11b or 11g and 5GHz for 802.11a.

Earlier the alliance was known as the Wireless Ethernet Compatibility

Alliance (WECA) but changed its name in October 2002 to better reflect the Wi-Fi

brand it wants to build. Also, while the term "Wi-Fi" was used only in

place of the 2.4GHz 802.11b standard, in the same way that "Ethernet"

is used in place of IEEE 802.3, the Alliance expanded the generic use of the

term in an attempt to stop confusion about wireless LAN interoperability.

The bottleneck



The widespread reliance on networking among businesses and the meteoric

growth of Internet and online services are strong testimonies to the benefits of

shared data and resources. With Wireless LANs, users can access shared

information without looking for a place to plug in making anywhere, anytime

business a reality.

Globally, wireless LAN has gained immense popularity in verticals like health

care, retail, manufacturing, warehousing, and academia as these industries have

profited from the productivity gains of using hand-held terminals and notebook

computers to transmit real-time information to centralized hosts for processing.

Reports suggest that in the highly networked markets of US and Europe, wireless

LANs are popular because of four main reasons–user mobility, speedy and less

cumbersome installation, installation flexibility, and scalability.

Why Wireless?
Mobility: Wireless LAN systems can provide LAN users with access to real-time information anywhere in their organization. This mobility supports productivity and service opportunities not possible with wired networks.
Installation Speed and Simplicity: Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through walls and ceilings. 
Installation Flexibility: Wireless technology allows the network to go where wire cannot go. 
Reduce Cost-of-Ownership: While the initial investment required for wireless LAN hardware can be higher than the cost of wired LAN hardware, overall installation expenses and life-cycle costs can be significantly lower. Long-term cost benefits are greatest in dynamic environments requiring frequent moves and changes.  
Scalability: Wireless LAN systems can be configured in a variety of topologies to meet the needs of specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to full infrastructure networks of thousands of users that enable roaming over a broad area.

The same does hold good for India because the overall cost of wireless LAN

hardware has nose-dived in the last two years. However, the real benefit is lost

due to the recurring spectrum fee payable to the wireless planning and

coordination (WPC) wing of the Department of Telecom (DoT). While the first

necessitates Rs 18,000 per year for frequent use, every additional user needs to

pay one-fourth or Rs 4,505 per year as the license fee for use on this ISM band.

Not to mention that in the case of first time users, it usually takes three-four

months to get a clearance from WPC. However, an existing user of Wireless LAN

can expect to get a clearance in two-three weeks’ time. Worst, an organization

also needs to approach the WPC for allocation of frequency for every new user it

adds on its wireless LAN network.

Why the license?



While no body debates the fact that spectrum being a scarce national

resource needs to be managed in order to ensure that radio services are able to

operate on a non-interference basis, what the industry and users find as most

irksome is the licensing of the ISM band. While a senior DoT official cites

security as a major reason for putting WiFi in the license bracket industry

analysts and experts feel that the real motive can be revenue. Their argument is

substantiated to a certain extent by certain statements in the WPC’s document

on economic considerations of spectrum pricing. It says "While a free

market in spectrum does not appear feasible due to technical, economic, and

social considerations; auctions, transferable and flexible spectrum rights, and

well-designed fees can enable a number of the benefits of a market approach to

be realized. Fees can promote efficient use of the spectrum, provided they

incorporate the correct economic incentives and are not set so low as to be

negligible or so high as to exceed what a market would set."

In fact, while gross injustice has been done to technology, by putting WiFi

in the licensing category, the WPC also seems to be unaware of the market

dynamics even in fixing the cost for using this spectrum and violating its own

principles. No wonder then that despite availability of technology, wireless LAN

implementation has been limited to only some companies, mainly MNCs like

Microsoft and Cisco or top IT companies in the country. In fact, had it not been

the issue of DPL, Indians would not have had to wait couple of more months to be

able to use the technology that had triggered the imagination of scientists

almost 20 years back.

Not that the government is not aware of the issue. It certainly is or else

the Minister for IT and communication, Pramod Mahajan would not have told the

9th session of the General Assembly and the 26th Session of the Management

Committee of the Asia Pacific Telecommunity (APT) about the government’s

proposed plan to delicense the indoor use of wireless LAN. Unfortunately, while

India is amongst the very few countries that still warrants a license for

products using WiFi, such announcements have been in the offing for more than

three months now. And even while the draft notification to this effect has been

made, it is applicable only for 802.11b, Bluetooth, and part of wireless LAN

products. While security concerns add up to a mere technical issue, the major

hindrance is the political will for policy changes.If, despite the minister's

efforts, the DoT still wants to cling to the ‘license raj’ for WiFi, the

least the government can do is to bring down the license fee and do away with

the per user structure, the need to seek permission for every new user, and

charging only a fixed annual fee from the organizations willing to go the

wireless LAN way.
