These services aid in protecting the customer’s network from access of
unauthorized users of the Private DataTAC wireless network as well as
protecting the confidentiality of user information over-the-air. For more
information on security services, consult the Private DataTAC 2.0 Network
Capabilities Specification or the WNG Operations Manual.
1.4.2.3 Motorola Wireless Communication Software (MWCS II)
MWCS II software, often referred to as middleware, is the communication
device driver for compliant wireless computers. MWCS II is used with
Microsoft® Windows® 95 or Windows 98 operating systems. MWCS II
provides the mobile application with access to the Private DataTAC network
through a variety of programming interfaces and allows application
developers to write their software to an industry standard applications
interface, e.g., WinSock (Windows Sockets). By interfacing through WinSock,
developers and customers have the flexibility to use the application software
on other IP-based systems should the need arise.
MWCS II is capable of handling all modem and over-the-air communication,
eliminating the applications’ need to interface with Native Mode.
