An access point (AP) for an indoor antenna distributed deployment environment provides an access service for a wireless terminal. The AP includes N radio frequency (RF) processing units and N*M RF switches (RFSs). Each RFS includes a public port and at least two branch ports. The at least two branch ports respectively connect with at least two antennas deployed in different indoor areas via RF feeders. The RF processing unit includes M RF chains. Each RF chain is connected to a public port of an RFS. The RF processing unit is to transmit a packet to the wireless terminal, based on a predetermined antenna combination for the wireless terminal.
