Description / Abstract: Scope of This Document
The set of documents that form the compatibility specification for UMB air interface systems.
In the following, "this specification" refers to the set of documents shown in Figure 1-1.
The requirements in this specification ensure that a compliant access terminal can obtain service through any access networks conforming to this specification. These requirements do not address the quality or reliability of that service, nor do they cover equipment performance or measurement procedures.
This specification is primarily oriented toward requirements necessary for the design and implementation of access terminals. As a result, detailed procedures are specified for access terminals to ensure a uniform response to all access networks. Access network procedures, however, are specified only to the extent necessary for compatibility with those specified for the access terminal.
This specification includes provisions for future service additions and expansion of system capabilities. The architecture defined by this specification permits such expansion without the loss of backward compatibility to older access terminals.
This specification is based upon spectrum allocations that have been defined by various governmental administrations. Those wishing to deploy systems compliant with this specification should also take notice of the requirement to be compliant with the applicable rules and regulations of local administrations. Those wishing to deploy systems compliant with this specification should also take notice of the electromagnetic exposure criteria for the general public and for radio frequency carriers with low frequency amplitude modulation.
