On publication of TIA/EIA-97-E as an ANSI approved standard, TIA/EIA 97-D will be withdrawn unless comments are received indicating a need to retain it. Such comments must indicate the reason retention should be considered by the committee. Unless comments to consider retention are received, TIA/EIA-97-D will be withdrawn by the Standards Secretariat of TIA on publication of TIA/EIA-97-E.

These technical requirements form a standard for signaling conformance in cdma2000 wireless packet data systems. These requirements ensure that a compliant mobile station and compliant network elements (PDSN, HA and RADIUS Server) can interoperate to execute tests in meeting the objectives stated in 1.1. Furthermore, network specific test requirements ensure compliant network elements for various error cases.

that the band 55.78-58.2 GHz is allocated to the Earth exploration satellite (passive), fixed, inter-satellite, mobile and space research (passive) services on a primary basis and the band 58.2-59 GHz is allocated to the Earth exploration satellite (pass
Radio-frequency channel arrangements for fixed wireless systems operating in the band 55.78-59 GHz
The ITU Radiocommunication Assembly, considering a) that the band 51.4-52.6 GHz is allocated to the fixed and mobile services on a primary basis; b) that No. 5.547 of the Radio Regulations (RR) identifies the 51.4-52.6 GHz band as being available for high-density applications in the fixed service (FS); c) that ITU-R should develop radio-frequency channel arrangements in order to make the most effective use of the spectrum available; d) that the propagation characteristics of the 51.4-52.6 GHz band are ideally suited for use of short-range digital point-to-point radio links in high-density applications in the FS networks; e) that in the frequency range a high antenna directivity is achievable even with small size antennas, increasing the density of equipment and further reducing risk of interference with same and other radio services; f) that differing applications licensed by various administrations may require different radio-frequency channel arrangements; g) that the applications in this frequency band may require differing channel bandwidths; h) that several radio services with various transmission signal characteristics and capacities may be in simultaneous use in this frequency band; j) that a high degree of compatibility between radio-frequency channels of different arrangements can be achieved by selecting channel centre frequencies within a homogeneous basic pattern, recommends 1 that administrations should consider the channel arrangement given in Annex 1 for FS system deployment in the frequency range 51.4-52.6 GHz.
