Coexistence performance in 951 958 MHz band – This sub-clause presents the coexistence performance of the systems coexisting in the in 951 958 MHz – band. An involving system is set as the victim while all other systems are set as the interferer, in order to understand the impact of the generated interference. All systems including the 802.15.4q systems and other 802 systems in the in 951 958 MHz band are set as the victim in a round-robin manner. – Parameters for Coexistence quantification The following sub-clauses present the parameters involved in quantification of coexistence analysis among the participating systems. PHY mode parameters of coexisting standards Table 21 shows the parameters for the PHY modes in each standard that is coexisting within the in MHz band.
