Coaxial RF dual-polarized waveguide filter and method

A first radio device comprising:

• at least one parabolic reflector;
• a Global Positioning System (GPS) receiver configured to receive a GPS signal and provide one or more of timing and location information;
• and
• radio circuitry configured for transmission and reception of radio-frequency signals from the at least one parabolic reflector and implementation of an adaptive synchronous protocol to reduce communication latency based on distance information between a second radio device in communication with the first radio device, wherein the distance information is determined from the location information from the GPS receiver,
• wherein the second radio device begins transmitting for a predetermined time period before the first radio device finishes a transmission, wherein the predetermined time period is based on the distance information.
