IEEE 802.1-2008 pdf download IEEE Recommended Practice for Local and metropolitan area networks Coexistence of Fixed Broadband Wireless Access Systems
1.1 Scope
This recommended practice revises IEEE Std 802.16.2″-2001. In particular, it specifies extensions andmodifications addressing two distinct topics. The first is coexistence between multipoint (MP) systems andPTP systems in the 10-66 GHz frequency range. The second is coexistence among FBWA systemsoperating in licensed bands within the 2-11 GHz frequency range. Updates to the existing content are alsoconsidered.
1.2 Purpose
The purpose of this recommended practice is to provide coexistence guidelines to license holders, serviceproviders, deployment groups, and system integrators. The specifications will facilitate the deployment andoperation of FBWA systems while minimmizing the need for case-by-case coordination
2.Normative references
This recommended practice shall be used in conjunction with the following:
ETSI EN 301 390 (2003-11), Fixed Radi Systems; Point-to-point and Point-to-Multipoint Systems;Spurious emissions and receiver immunity at equipment/antenna port of Digital Fixed Radio Systems.
ITU-R Recommendation F.1509 (02/01): Technical and operational requirements that facilitate sharingbetween point-to-multipoint systems in the fixed service and the inter-satellite service in the band25.25-27.5 GHz.2
3. Definitions and Abbreviations
For the purposes of this recommended practice, the following terms and definitions apply. The AuthoritativeDictionary ofIEEE Standards Terms, Seventh Edition (B3013, should be referenced for terms not defined inthis clause.
Other standards (e.g., ITU-R Recommendation F.1399-1 (2001-05) (B37]) employ comparable definitionsand abbreviations to those that follow. However, while comparable, they differ in a number of cases.
3.1 Definitions
3.1.1 authorized band: The frequency range(s) over which an operator is permitted to operate radiotransmitters and receivers.
3.1.2 automatic transmit power control (ATPC): A technique used in broadband wireless access (BWA)systems to adaptively adjust the power of a transmitter to maintain the received signal level within somedesired range.
3.1.3 base station (BS): A generalized equipment set providing connectivity, management, and control ofthe subscriber stations (SSs).
3.1.4 block bandwidth (B): The contiguous authorized bandwidth available to an operator
3.1.5 broadband: Having instantaneous bandwidths greater than MHz and supporting data rates greaterthan about 1.5 Mbit/s.
3.1.6 broadband wireless access (BWA): Wireless connectivity in which the connection(s) capabilities arcbroadband.
3.1.7 channel bandwidth: For single carriers, the bandwidth assigned to individual carriers within a blockThis may difer for different carriers within a block. The occupied bandwidth of a carrier within a channelmay be less than or equal to the bandwidth of a channel. For a multicarrier transmission using a commonamplifier stage, the sum of all composite carriers.
3.1.8 cross-polar discrimination (XPD): For a given direction, the difference in decibels between the peakco-polarized gain of the antenna and the cross-polarized gain of the antenna.
3.1.9 dBi: In the expression of antenna gain, the number of decibels of gain of an antenna referenced to the0 dB gain of a free-space isotropic radiator.
3.1.10 digital modulation: The process of varying one or more parameters of a carrier wave (e.g..frequency, phase, amplitude, or combinations thereof) as a function of two or more finite and discrete statesof a signal.
