Typical ProjectP a ge 8

Outdoor RF Repeater Speedway Coverage

Weak signal area

Problems: Because of the shield of the mountains, obviously there is weak signal area and blind area along the speedway.

Solution: Install outdoor repeater to amplify signal received from BTS and cover the weak signal area and blind area by use of directional antenna (mobile antenna) to enlarge BTS coverage area.

Notices in integration: Outdoor repeater with high output power required high isolation to avoid self-excitation. Choose corner reflector antenna as mobile antenna and short backfire antenna as donor antenna because of their good F/B to meet isolation requirement. Choose the best antenna location to make use of houses obstruction to increase the isolation between donor and mobile antenna. Donor antenna short backfire antenna

Problems: The target coverage area is a mountainous area in the north Philippines.It is required for road coverage with 2km radius in order to make call even on the edge of coverage area.

Notices in integration: Choose panel antenna as mobile antenna as well as paraboloid grid antenna as donor antenna with high gain and good F/B. Because antenna with high gain will help to get maximum donor signal and with good F/B will satisfy the requirement of isolation.DNot e:
