Smartner Unplug+Play

Smartner Unplug+Play's architecture is designed to support wireless data applications. In particular, it leverages the opportunities created by
the convergence of wireless Personal Area Networking (e.g. Bluetooth)
and wireless Wide Area Networking (e.g. GPRS, 3G), with focus on addressing characteristics unique to networks and devices operating in this context:

• Intermittent connectivity
• Limited bandwidth and high latency
• Cost control: visibility of cost, optimisation of data,
  selection of transport bearer
• Quality of service
• Device diversity
• Technology diversity
• Implementation diversity
• Power management: power saving, case of power loss,
  application-level power control
• Dynamic addressing of mobile devices
• Security: physical security, transmission security,
  infrastructure security
• Cost of administration
• Dynamic configuration
• Scalability

The full unplug+play architecture consists of three main elements.
Client software that resides on wireless devices, server software that resides within an organisation's intranet, and relay servers which mediate communication over the WAN.
