Help in Designing Microwave Communication System

Hi guys, for our final project, we are asked to design a microwave communication system.

DESIGN REQUIREMENTS 1. A point-to-point digital microwave communication system design between Batangas State University Main Campus I and Main Campus II

1. The line-of-sight transmission is the basis of the design.

2. The transmission mode is full duplex, digital transmission using any type of network topology working at 13GHz frequency band

3. The microwave communication system that can be used as a reliable data communication link between two main campuses.

4. The link must have a minimum packet link capacity of 4Gbps.

5. Design reliability is 99.999998%.

Any help on where can we start and what antenna can we use to satisfy these? Just any help would be appreciated. Thank you so much
