CB is short for Citizens Band...


CB - Citizens Band is a range of frequencies around 27 MHz which were permitted for use by ordinary citizens without a license.

Other frequency bands are allowed to radio amateurs who have passed various exams.

Some frequency bands are permitted on the basis that the equipment supports suitable freqency hopping protocols to share the bandwidth. Standards like Bluetooth and WiFi fall into this category.
