BTS Booster OverviewDue to rapid changes in wireless network environment, network operators are now faced with various infrastructure solutions and cost issues in upgrading wireless network. HFRs TM-MCPA product provides cost effective capacity/coverage upgrade solution. Sharing of existing RF cable and antenna, and coverage extension are the major advantages of this system. TM-MCPA allows for a complete link budget solution by efficient network infrastructure resource management.

TM-MCPA Features TM-MCPA Features Increase channel count per antenna at the same power level Seamless BTS field integration with RF bypass solution Tower-Mount feature to maximize output power at the antenna Protect from threshold power level, temperature and VSWR

TM-MCPA Managements TM-MCPA ManagementsTM-MCPA can be easily monitored and controlled using built-in microprocessor. Following extensive features are included for managing system easily.
