WiFi makes an impact on India Inc
Though WiFi-enabled notebooks havent really taken off in India, Akhtar
Pasha finds that WiFi and handhelds make a formidable combination when it comes
to data capture in manufacturing and retail

Mark Mathias says that hundreds of Simputers could
be deployed in a WiFi environment, going by current trends |
Smart handheld devices (SHDs) are finding takers in Point of Sale (PoS), manufacturing
shop floors, department stores, vehicle fleets, courier services, hospitals,
warehouses and in any sphere of business where the work force is mobile and
real-time data collection is important. Kaushik Chandra, CTO, PricewaterhouseCoopers
(PwC) says, The sheer portability and simplicity of these SHDs helps make
this a reality. SHDs will evolve into programmable devices that are tailor-made
for specific applications and ease of use will be the unique selling point.
PwC believes that there is a huge potential market in e-governance, retail,
pharmaceuticals, manufacturing and logistics where theres a requirement
for compact, low-cost computing devices. WiFi on handhelds is a technology that
can help solve this business problem. Dr Swami Manohar, CEO, Pico Peta Simputers
says, SHDs could outnumber notebooks in the next 18 months.
Pervasive WiFi
A WiFi ready notebook costs at least Rs 65,000 (including taxes) and it weighs
between 2 and 2.5 kilograms. SHDs are 10 to 20 times lighter than notebooks
(113 to 280 grams); they fit into your shirt pocket and start at sub-Rs 10,000
prices.
Many Indian enterprises are trying out handhelds in conjunction with WiFi or
GPRS/CDMA networks for wireless data capture. Leonardo Engineering is using
PalmOne PDAs and Bluetooth. The company is evaluating WiFi as a substitute for
Bluetooth. Nova Nordis is piloting PalmOne PDAs communicating over a CDMA network.
Cafe Coffee Day is going to conduct a pilot where PDAs will be used to drastically
reduce serving time and errors by beaming orders over a WiFi network.
The simplicity of WLAN technology and dropping prices (just plug in a wireless
access point costing Rs 3,000 to Rs 15,000 and you are unwired) are definitely
a plus. The problem till now has been that access devices are bulky and expensive.
With WiFi going everywhere, that particular problem has been solved, at least
from a technology standpoint.
A Smartphone with integrated GPRS or Bluetooth is an alternative to a PDA. That
said, the relatively small amount of memory and storage on a Smartphone makes
this kind of solution impractical. A handheld is more powerful in terms of processing
power, memory and storage and therefore it appears to be the prime candidate
for taking WiFi into every nook and cranny of Indian business.
Unwired PDAs

Shivaprasad N V says that Café Coffee Days plan to introduce
orders transmitted through handheld devices on WiFi would differentiate
them from the competition |
Getting PDAs to operate in a WiFi network is a two-step process.
- Configuring access points
A PC has to be connected to the access points console
port using a serial cable. An IT administrator can now use terminal software
to view access point configuration screens and change settings, such as radio
channel, transmission power and the like. Access points can use DHCP (dynamic
host configuration protocol) to automatically get IP addresses from a DHCP server.
For this youll need a few accessories. A card that supports 802.11b or
a compact USB wireless adapter such as D-Links DWL 122 (if the PDA should
have an USB port) or a CompactFlash Card. Once thats taken care of its
as simple as installing the WiFi card drivers on to the PDA, inserting a WiFi
CF (Compact Flash) card, going to Start -> Settings -> Connections ->
Network adapters and selecting your WiFi card. Then pick Use server-assigned
IP address and the PDA is now ready to operate in a wireless environment.
Café Coffee Day, a division of Amalgamated Bean Coffee
Trading Company is a pioneer in the modern coffee business. It also operates
a retail chain of coffee shops that are branded as Café Coffee Day outlets.
The company is conducting a pilot that will do away with glitches that plague
the process of order taking and delivery in a coffee bar. The scenario envisioned
is that waiters use smart handheld devices (SHDs) and send your order over a
WiFi network to a Point of Sale terminal that, in turn records the order and
passes it on to the kitchen. The end result? Your order is executed in a fraction
of the time that it usually takes to get a latte to your table.

According to Swami Manohar, smart handheld devices
could outnumber notebooks in the next 18 months |
Shivaprasad N V, manager-MIS, Café Coffee Day says,
A service like this can differentiate us from the competition. The
company plans to use smart handheld devices (it is still evaluating PalmOne,
Casio and a customised handheld) in tandem with a WiFi network. If all goes
well, the first phase of Café Coffee Days WiFi rollout will end
up putting 100 to 150 SHDs into three outlets in Bangalore by July 2004. Phase
two will see the pilot being extended to outlets across the country.
Auctioneers and bidders taking part in the Mandi Project in Madhya Pradesh will
use Encore Simputers with integrated wireless LAN CF (Compact Flash) cards to
connect to a WLAN for placing their bids online. A similar pilot is being tried
by the Tobacco Board, again using the Encore Simputer. Mark Mathias, vice president-hardware
development, Encore Software says, You could end up with hundreds of Simputers
being deployed in a WiFi environment.
Wireless SHDs can also be useful for managing hotspots. Sifys network
service engineers have been using notebooks to fix network-related problems
at Sifys iWay wireless base stations. Engineers initiate a telnet session
to fix problems. As the service engineer has to climb to reach the equipment,
toting a notebook isnt the easiest way to manage things. Sify has decided
to use the Amida Simputer with an USB adapter. Rustom Irani, CTO, Sify. says,
They can do the same work on a smaller and cheaper device that fits into
a shirt pocket.
Chandra of PwC says, It makes business sense to keep your information
updatedthe more current the information is, better is the value derived
from it. Delivery personnel can key in quantities of delivered products
and send this information to the inventory database in near real-time. This
will help a production controller schedule manufacturing to get optimum value
from raw materials while keeping inventory levels low. Theres no doubt
that the combination of PDAs and wireless, be it WiFi, GPRS or Bluetooth, will
have a tremendous impact on how business is conducted in this country.

The wireless avatar of Ethernet, the most popular LAN protocol. |
Low power consumption; supports voice. |

| Cons |
Initial client devices (mostly notebooks) have been expensive. |
Bluetooth has mostly been supported in high-end phones, making
it an expensive proposition for deployment. There's some scope for interference
with 802.11b (WiFi). There was a recent security flaw revealed. "Bluesnarfing"
lets an attacker exploit this flaw to read, modify and copy a phone's address
book and calendar without leaving any trace of the intrusion. |
Shared bandwidth means that as the number of users rises,
bandwidth available to each user drops. Network congestion is a fact of
life in these networks. |
