Table 108 BHM Evaluation tab attributes - BHS
Attribute Meaning
Index This field displays the index value that the system assigns (for only this
page) to the BHM where this BHS is registered.
Frequency This field displays the frequency that the BHM transmits.
Channel Bandwidth The channel size used by the radio for RF transmission. The setting for the
channel bandwidth must match between the BHM and the BHS.
Cyclic Prefix OFDM technology uses a cyclic prefix, where a portion of the end of a
symbol (slot) is repeated at the beginning of the symbol to allow multi-
pathing to settle before receiving the desired data. A 1/16 cyclic prefixes
mean that for every 16 bits of throughput data transmitted, an additional bit
is used.
