Multiple-input multiple-output (MIMO) repeater system

A bi-directional diversity repeater, comprising at least:

• a first interface port;
• a second interface port;
• a 1st first-direction signal amplification and filtering path communicatively coupled between the first interface port and the second interface port;
• a 1st second direction signal amplification and filtering path communicatively coupled between the first interface port and the second interface port;
• a third interface port;
• a fourth interface port;
• a 2nd first-direction signal amplification and filtering path communicatively coupled between the third interface port and the fourth interface port;
• and
• a 2nd second direction signal amplification and filtering path communicatively coupled between the third interface port and the fourth interface port,
• wherein:
• the 1st first-direction signal amplification and filtering path and the 2nd first-direction signal amplification and filtering path amplify a same first-direction frequency range and the 1st second-direction signal amplification and filtering path and the 2nd second-direction signal amplification and filtering path amplify a same second-direction frequency range;
• the first interface port and the third interface port are configured to be communicatively coupled to a diversity donor antenna;
• the second interface port and the fourth interface port are configured to be communicatively coupled to a diversity server antenna;
• a first diversity sub-repeater that includes the first interface port and the second interface port;
• and
• a second diversity sub-repeater that includes the third interface port and the fourth interface port,
• wherein the first diversity sub-repeater is packaged with the second diversity sub-repeater in the bi-directional diversity repeater to achieve a multiple-input multiple-output (MIMO) capability for the bi-directional diversity repeater.
