In this article we have focussed on LEAP and WhiteBerry in terms of a specific application, namely, interpersonal Mobile Messaging. But this is just the beginning - WhiteBerry is also the starting point for a more general set of wireless applications and usages. In the following paragraphs we describe a few examples.
All this existing capability can be immediately brought to the wireless world by means of WhiteBerry. In other words, in addition to providing interpersonal Mobile Messaging services, WhiteBerry can also function as a generalized efficient message transfer infrastructure, which generic applications can use to deliver message-related services to the user.
Note that the implied message shortness of the WhiteBerry model is not necessarily in conflict with richness of content. This simply means that such content must be appropriate to the wireless and mobile domain - it must bring added value to the user, without violating message size restrictions. An example of such content is the use of embedded responses, in which the message originator provides the recipient with a set of pre-defined, multiple-choice replies from which to select .
A good example is Instant Messaging. Note that in this application the exchanged messages are by nature very short, and therefore the efficiency of EMSD brings a significant performance premium. The LEAP protocols can readily be used to extend existing Instant Messaging capabilities to mobile devices. This extension of the WhiteBerry model requires only simple integration with existing Instant Messaging solutions, and with existing facilities such as Presence Management and Location Management.
Also, note that LEAP itself has broader scope than just the WhiteBerry Mobile Messaging model. WhiteBerry is part of a larger family of LEAP-based applications, which also includes other applications such as LEAP-based web applications. These applications can be tightly integrated, so as to provide a consistent package of capabilities to the user.
Note in particular that usage of ESRO is not limited to WhiteBerry. ESRO is a generic enabling foundation, upon which a variety of efficient applications can be built. For more information on generalized uses of ESRO, refer to the Manifesto article ESRO: A Foundation for the Development of Efficient Protocols.
In Operation WhiteBerry we have established a framework which can bring tremendous benefits to the wireless industry and the consumer. There is a great deal more that can be done by extending and building on this framework. We will continue to expand on this framework and work to bring it to its full potential.
