A method and apparatus for peer-to-peer services have been described. Thus, the mounting brackets are detachably mounted on the upright posts to support the support boards so that the support boards are selectively mounted between the upright posts, and the number of the support boards can be adjusted freely and randomly according to a user’s practical requirement. Based on the evaluated airlink quality measurement, the method determines the uplink transmit power level that the mobile should be using for the current block, and adjusts the transmit power level, if necessary, for the current block. One example of a signal used to generate the metrics comprises the 14 synchronization symbols which make up part of an IS-136 standard signal.
