Portable radios are designed for individual use by emergency responders and typically have a more limited transmission range compared to mobile or base radios, which are often installed in vehicles and designed for more powerful transmissions. This limitation in range is primarily due to the lower power output of portable radios, making them ideal for close-range communication during firefighting, medical emergencies, or other on-scene responses.

While mobile radios are capable of greater range due to their installation in vehicles and higher power output, and base radios are often connected to external antennas to increase their transmission capabilities, portable radios remain a vital tool for direct communication between team members in the field. Therefore, recognizing their limitations in comparison to mobile or base radios is crucial for understanding their application in the EMS communication landscape.
