Wireless adoption in the real world

As a consequence, the essential technique for mobility is to keep one's mobile device (typically a PDA, notebook, or smartphone) synchronized with one's office network resources, including e-mail and documents of all forms. For an examination of this process, see Synchrologic's white paper "Mobilizing Enterprise Applications with Synchronization".

  • Instant messaging - While e-mail, paging, and related messaging technologies remain important to enterprise wireless users, they really are designed to provide what we call "temporal decoupling" between sender and recipient. That is, a variable amount of time can go by between messages, with no loss of value. We're gradually seeing, however, an increasing role for wireless instant messaging which in many ways parallels the effect that instant messaging is in general having on Internet-based communications. For an example, see http://www.air2web.com/2IM.jsp ">Air2web's 2IM product.
  • Building-to-building bridges - Finally, many firms have discovered that it makes sense to use wireless links between buildings in a campus or metropolitan-area setting to connect both voice and data networks. Such point-to-point and point-to-multi-point products have performance that can match that available on wire. The general way to evaluate whether a bridge is for you is to compare the cost to lease the wireless equipment against the cost to obtain capacity from a carrier of some form. You may be surprised to find that bridges are cheaper in many cases, especially over the life-cycle of a given installation. The only other key factor is to make sure that the geometry of the proposed installation works (line of site is important, but not always required), and there may be other considerations if you use a licensed wireless technology. For examples of enterprise-class bridges, see:

    Alvarion's BreezeLink
  • Aperto Networks' PacketWave 600 Series Wireless Bridges

    And, of course, we've not even mentioned wireless LANs here, which are having a profound impact on the enterprise both in-building and via public-access hot spots. As we've noted before, WLANs and cellular offerings end up merging seamlessly over time. And that's really what we want in enterprise applications, after all - transparency, ease-of-use, and uniformity. With the rise of wireless Web services, the increasing availability of wireless broadband, and subscriber units available at prices that don't break the corporate bank, we're getting ever closer to wireless as an enterprise essential.
