Developing Practical Wireless Applications

Extending the application-base

With an already established range of applications (Bluetooth Profiles) and the poten-

tial forthcoming application base when the marriage of Bluetooth and UWB has

been consummated, then there is clearly an opportunity for many individuals and

manufacturers to develop new applications. Furthermore, the current specification is

being upgraded to reflect new changes to the core specification and new profiles. A

change is inevitable as we see the marriage of Bluetooth and UWB evolve from its

flimsy paper anniversary to a more solid foundation that may become wood denot-

ing five years of a successful relationship. Naturally, with an established relationship

there’s always the possibility of complacency and the allure of a seven year itch.

Fortunately the Bluetooth SIG, an incorporated organization responsible for archi-

tecting and shaping Bluetooth’s future, creates a series of Marketing Requirement

Documents (MRDs) that disclose future usage scenarios. These MRDs are the foun-

dation from which the specification has evolved and further MRDs are created to

provide new usage scenarios, that is, new ideas that may result in new applications

(or profiles). You may consider the MRD, as an internal business justification process

within the SIG; these usage scenarios are submitted to external reviewers for their

comments.

Foundation Profiles

The following table (Table 11.7) lists the original set of Bluetooth profiles proposed

in the Specification of the Bluetooth System: Profiles, v1.1. Incidentally, the LAN

Access Profile (LAP) has been disbanded and is now replaced with the Personal Area

Networking (PAN) Profile. The number of profiles outlined in this table are prevalent

in most Bluetooth wireless products and have enjoyed a moderate success within the

Bluetooth community.

The Adopted Profiles

The adopted profiles (as shown in Table 11.8) are a clear diversification from the

founding profiles, perhaps an acknowledgement to the SIG that it needs to adapt its

current application portfolio to a more multimedia-centric application base, which

(we are told) the consumer desperately needs to fulfill.
