900 MHz cordless phones
In the mid-1990s, many cordless phone manufacturers started producing phones that used the lower and upper ends of the 33–centimeter band for communication between the handset and base. These phones, which are regulated by Part 15 of the FCC's regulations, have made amateur use of the upper and lower end of the 33 centimeter band somewhat tricky due to the number of these phones used by the general population. Part 15 devices, by law, must accept interference from any licensed radio service with which they share frequencies.
