If an individual wants a scanner with more range, they may select a scanner that include VHF and UHF capability which increases the frequency to 300Mhz to 3Ghz. These frequencies are often used by agencies on their two-way radios.

An individual can store thousands of channels on their scanner. It is possible to scan hundreds of frequencies per second. There are scanners manufactured that also can follow APCO-PC 25 digital frequencies and trunked systems. These frequencies are used by emergency services and security agencies in the federal, state, and local governments. Some of the transmissions of these agencies is encrypted and mobile radio scanners cannot receive them for security purposes.

There are many times when the mobile radio scanner that one selects will provide security. This is especially true of individuals who travel a lot or live in areas with severe climate changes.
