With the speedy increase of mobile data services, LTE networks develop rapidly. All operators are facing the challenges of multi-band and multi-RAT network as GSM, UMTS, and LTE networks will co-exist for a long period.
To adapt multi-band and multi-RAT networks, legacy antenna systems must be reconstructed. During the reconstruction process, the antennas, combiners, tower-mounted amplifier (TMA), and remote electrical tilt (RET) antennas will be combined, forming a complex antenna system.
Antenna system reconstruction encounters the following problems:
Huawei Multi-RAT Antenna System evolution solution, relying on rich service experience, methods, professional tools, and professional team, provides customer a customized antenna system design service.
Antenna system component reuse, saving materials cost
ACP algorithm to improve planning accuracy for good network performance
