Feedsee Electronics : MPLS Antenna Beam Phase Control : Direction and width selection for cellular communications systems
KMW Communications has been granted a patent for Multi Line Phase Shifter (MLPS) for Antenna Beam Phase Control. The patent protects antenna beam phase system control of beam direction and beam width selection for use in cellular communications systems. The benefits of the technology protected are real time RF management for traffic, capacity, coverage, and QoS; elimination of tower crew expenses for antenna beam adjustments; reduction of capital expenditures for new antennas; and ease of installation similar to conventional antennas. The MLPS uses a noncontact dielectric method to alter the DC phase in the antenna pattern transmission cables to control antenna patterns and beams. Unlike conventional antenna phase shifters, no moveable phase shifter sleeves are interfaced to the antenna patterns.
