Demand in the land mobile service is on the increase due to annual growth as well as to new data-based service requirements. This has led to the development of more spectrally efficient technologies utilizing digital modulation and in many cases trunking. These technologies are being introduced in systems worldwide to accommodate this demand.
This Report provides information on many of the technology trends concerning radio access networks foreseen at the time of preparation of Recommendation ITU-R M.1645.
This Report consolidates the DFS test methodology used and findings across several administrations, as shown in several annexes. Information is provided on the test methodologies in place in various administrations and/or regional groups to test compliance with DFS requirements. These procedures may be updated over time, and as technology evolves. As a result, web links are provided (in some cases) to the test methodologies themselves, so that the most up-to-date information may be obtained.

TDM Emulation service (TDM-E) is a method for cable operators to deliver T1, E1 and NxDS0 emulation services thatmeet or exceed the quality requirement of applications that use such services. This Recommendation is part of theCableModem family of Recommendations and in particular, defines the TDM-E architecture and components.
This document contains the advanced IP network architecture especially in views of end-user functions for control and management. The future IP network is not just focused into the provider provisioned single network. It equally considers the integrated environments of fixed/wireless network elements to accommodate computer systems, home peripherals and intelligent appliances. The future IP network may compromise of heterogeneous requirements of service quality and physical interface from network and computer and consumer equipments.
