There is disclosed an improved base station for communicating with communication units in a wireless messaging system. According to an advantageous embodiment, the base station comprises: 1) a transmitter that is capable of transmitting messages to the communication units in a forward-channel having a first frequency range; 2) a receiver that is capable of receiving messages from the communication units in a reverse-channel having a second frequency range; and 3) an antenna that is capable of transmitting the forward-channel messages at a first angle of electrical downtilt below the horizon and receiving the reverse-channel messages at a second angle of electrical downtilt, wherein the second angle of electrical downtilt is less than the first angle of electrical downtilt.

Antenna system for narrowband communications systems and method of operation

A communications controller is disclosed for use in a wireless communication system having a plurality of antennas capable of simulcasting forward-channel messages at a first downtilt angle below horizon and receiving reverse-channel messages at a second downtilt angle, wherein the second downtilt angle is less than the first downtilt angle. The communications controller, which is associated with the plurality of antennas, is capable of (i) scheduling transmission of ones of the reverse-channel messages at a same frequency in a same time slot, and (ii) receiving reverse-channel messages of two communication units proximate a local antenna at separate more remote antennas in response to the second downtilt angle of the separate more remote antennas.
