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
theres 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 Bluetooths 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.
