B
902 MHz to 928 MHz
C
50 MHz to 54 MHz
D
222 MHz to 225 MHz
Answer Notes
Frequency allocations dictate not only who can transmit, but also who is protected from interference. When amateur radio is allocated as a secondary service in a specific band, operators must accept any interference caused by primary users.
The 902 MHz to 928 MHz band (the 33-centimeter band) is heavily shared. It is designated for Industrial, Scientific, and Medical (ISM) equipment as well as other primary services. Because amateurs operate on a secondary basis here, they are not protected from interference generated by these primary users.
In contrast, the 50 MHz, 144 MHz, and 222 MHz bands give amateurs primary status in Canada. In those segments, amateur operations are protected from interference by other services.
