3、ed without license from IHS -,-,- NOTICE FROM THE TELECOMMUNICATIONS INDUSTRY ASSOCIATION TIA/EIA Engineering Standards and hblications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvemen
4、t of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and hblications shall not in any respect preclude any member or nonmember of TIA/EIA from manufacturing or selling products not conforming
5、to such Standards and hblications, nor shall the existence of such Standards and hblications preclude their voluntary use by those other than TIA/EIA members, whether the standard is to be used either domestically or internationally. Standards and hblications are adopted by TIA/EIA in accordance wit
6、h the American National Standards Institute (ANSI) patent policy. By such action, TIA/EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or hblication. Note: The users attention is called to the possibiliS, that complian
7、ce with this document may require use o f one or more inventions covered by patent rights. By publication o f this standard, Interim Standard, or TSB, no position is taken with respect to the validio o f those claims or o f any patent rights in connection therewith. The patent holder) so far identif

9、andards contain information deemed to be of technical value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedural part of the development of an American National Standar
10、d (ANS). Interim Standards should be reviewed on a periodic basis by the formulating Committee and a decision made on whether to proceed to develop a TIA/EIA Standard on this subject. Interim Standards must be upgraded or cancelled by the Committee before the end of their third year of existence. hb
11、lication of this Joint Interim Standard for trial use and comment has been approved by the Telecommunications Industry Association. Distribution of this Joint Interim Standard for comment shall not continue beyond 36 months from the date of publication. It is expected that following this 36 month pe

19、rtion of a burst. Average EIRP: The burst EIRP averaging over at least 200 bursts. 3.2 Abbreviations The abbreviations used in this document are given in GMR-1 01.004 i. 4 Frequency bands and channel arrangement 4.1 Frequency bands and duplex method MESS operate in frequency division multiplexing (F
20、DM) mode at Gband in two paired 34 MHz frequency bands, which are allocated world-wide for land mobile satellite service (LMSS). The frequency bands are: 0 MES receives: 1525.0 to 1559.0 MHz 0 MES transmits: 1626.5 to 1660.5 MHz In the FDM scheme, Gband downlink (forward) radio frequency (RF) carrie
21、rs in the satellite-to-MES direction are paired with Gbanduplink (return) RF carriers in the MES-to-satellite direction at a frequency offset of 101.5 MHz. 4.2 RF carrier spacing and designation The 34 MHz operating band is divided into 1,087 paired carriers, with carrier spacing of 3 1.250 l otherw
22、ise, the carrier is OFF. Transmitted power is measured in terms of EIRP (effective isotropic radiated power) averaged on each burst, and EIRP averaged over a set of at least 200 bursts. The former is termed “burst EIRP“, and the latter is termed “average EIRP“. Burst EIRP is measured by averaging th
23、e instantaneous EIRP over 90% of the active portion of each burst. Average EIRP is measured by averaging the instantaneous EIRP over 90% of the active portion of the burst and further averaging over at least 200 bursts. EIRP shall be measured in the direction from the MES at which maximum power is t
24、ransmitted, as observed in the far field. EIRP measurements may be conducted through separate measurements of output power at the antenna terminals and maximum antenna gain. Measurement procedures are beyond the scope of this document. The average EIRP of various terminal types shall satisfy the lim
