Abstract: The present disclosure provides a device for wireless access, which pertains to the technical field of wireless network. The device for wireless access includes a device body; a radio frequency circuit disposed inside the device body; and a plurality of antenna units disposed on an external surface of the device body, each of the plurality of antenna units being connected to the radio frequency circuit; wherein each of the plurality of antenna units comprises an antenna oscillator, and the antenna oscillators on each two adjacent antenna units of the plurality of antenna units are misaligned with each other. By disposing antenna oscillators of adjacent antenna units on the misaligned regions of the respective antenna unit, the interference of co-frequency signals between adjacent antenna units may be reduced, and the isolation of adjacent antenna units may be enhanced. Thus, adjacent antenna units may be disposed at a reduced distance therebetween.

Abstract: 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.
