Multiple-port signal boosters

A signal booster, comprising:

• a first interface port;
• a second interface port;
• a signal splitter device that includes a first splitter port, a second splitter port, and a third splitter port, the signal splitter device configured such that a first direction signal that is received at either of the second and third splitter ports is output at the first splitter port and a second direction signal, which traverses in a direction opposite of the first direction signal, received at the first splitter port is output at each of the second and third splitter ports;
• a main booster that includes a main first direction amplification path and a main second direction amplification path that are each communicatively coupled between the first splitter port and the first interface port;
• and
• a front-end booster that includes a front-end first direction amplification path and a front-end second direction amplification path that are each communicatively coupled between the second splitter port and the second interface port.
