[[Part 15]] band - Motorola literature, sales paperwork and manuals list the frequency as "900 MHz [[ISM]] band", “902-928 MHz ISM band”, “900 Band”, “902-928 MHz Part 15 ISM Band” and other terminology. The 900 MHz band is an ISM band (915 MHz center frequency) and also the [[Ham_radio#Amateur_Radio_Bands_VHF_UHF_and_up|the 33cm]] amateur radio band shared spectrum. Usually simply called the 900 MHz band or the 900 band…or 915 MHz for [[LoRa]] folks and other applications.

The DTR 900 MHz digital [[Business Radio|business radios]] offer performance comparable with UHF walkie-talkies as far as in-building coverage goes. Hopsets 10 frequency sets of 50 frequencies each. Spacing within each hopset is 500 kHz. Since each hopset is 50 kHz offset from the previous hopset, the ''overall'' channel spacing is 50 kHz.
