Wireless technology is still in its infancy and as technology
changes so does the business model of the service providers.

change the possible business models.
As technologies such as WLAN and Bluetooth improve,
they will serve a portion of consumers need for connectivity.
Wireless operators have traditionally offered services only on
licensed spectrum as it protected them from undue competition.
The future will see operators offering services over both
licensed and unlicensed spectrum reflecting a shift towards the
need for seamless management of wireless access across various
networks.
Operators of the future will need to compete not only against
the few that have purchased licensed spectrum but also those
that offer services in the unlicensed band. We believe that most
enterprise and consumer users will lean towards solutions that
integrate the authentication, customer care, and billing of as
many network access technologies as needed for their particular
use. Operators with licensed spectrum will still have an edge over
those without licenses, as many users will resist the hassle of separate
subscriptions for access needed on different overlapping
networks that will often service the same laptop or mobile device. 215

CELLULAR THREAT OR BENEFIT?
Some may see WLAN and Bluetooth access as competition for
cellular access, it’s more likely to evolve as an extension of cellular
operators offerings. Wireless operators need WLAN technology
to offload heavy localized traffic especially in indoor
environments. Recent studies support the claim that 3G operators
will need WLAN technology to handle the most demanding
users in dense areas. The fact that WLAN uses unlicensed
spectrum will not mean that operators wouldn’t need to spend
money to operate these systems as they will need the same
centralized network management, subscriber identification, security,
and roaming systems in place to manage this last portion
of the wireless transmission. WLANs could be configured to
cache frequently accessed content and reduce the data traffic
carried by the backbone of the system that would be using
licensed spectrum.
Other issues ill need to be overcome for WLAN technology
to peacefully exist with other systems that use the unlicensed
spectrum. Congestion is a real possibility as there is no limit to
the number of networks and traffic that could try to use the
frequency in a given area. Security is an issue that is growing
in importance as more and more users have a WLAN card and
can easily walk or drive within range of many corporate systems.
Many of these systems have been installed with no
change to the equipments factory settings enabling anyone that
knows the common factory settings and passwords to gain
access to corporate networks. Interference will also be a challenge
especially for companies such as Starbucks since other
devices such as Microwave ovens can generate frequencies
close enough to 2.4 GHz to disrupt the WLAN transmission
every time they heat up a muffin. 214

BLUETOOTH—SHORTER RANGE BUT LOWER POWER CONSUMPTION
For devices that are too small or unable to provide the power
needed to operate a WLAN card there is a new technology in
the works called Bluetooth. Similar to WLAN technology,
Bluetooth is designed for smaller devices with lower power
consumption. This lower power means a shorter range of transmission;
Blue tooth will initially be limited to approximately 30
feet. With potential throughput on par with WLAN, Bluetooth
will compete with WLAN for short range access for laptop PCs
and printers. Bluetooth will be more suitable for smaller
devices and operates on a peer-to-peer configuration that
establishes a piconet (a series of connected devices that pass
the data along to one another in a kind of fire brigade manner)
to extend the reach back to a network when available.
Bluetooth will be used more often in scenarios where data is to
be exchanged between two or more devices such as between
multiple PDAs or between a PDA, cell phone, and a printer.
