Officially called the "Industrial/Business Radio Pool" under 47 CFR 90.35, 47 CFR 90.75 and others...all within part 90 of the FCC rules (which covers land mobile radio in general). Known as LMR (land mobile radio), PMR (professional mobile radio) or PLMR (professional land mobile radio) as well as just the business band.

High HF and VHF/UHF Land mobile radio service authorized under Part 90 (Land Mobile Radio Services) of the FCC rules. FCC eligibility verbiage states: Persons primarily engaged in any of the following activities are eligible to hold authorizations in the Industrial/Business Pool to provide commercial mobile radio service as defined in part 20 of this chapter or to operate stations for transmission of communications necessary to such activities of the licensee: (1) The operation commercial of business activity; (2) The operation of educational, philanthropic, or ecclesiastical institutions; (3) Clergy activities; or (4) The operation of hospitals, clinics, or medical associations. The FCC has allocated a massive amount of frequencies for the Business/Industrial Radio Service (commonly referred to as "Business Radio" or "Business Radio Service"). The FCC allows use of frequencies in the 2000 to 25000 kHz (2-25 MHz) band for business purposes, only if frequencies above 25 MHz will not satisfy the requirements of the user, in other words, in special cases only. In these cases, the businesses in question are assigned frequencies in the HF fixed and mobile bands.

Business Radio is not to be confused with license free or simple license services available for land mobile and portable or walkie-talkie radio purposes in the United States. These VHF/UHF services include FRS and GMRS, MURS and CB. FRS, MURS and CB are all heavily used for business purposes and/or as a low cost alternative to the hassle of business band (getting a FCC license, etc.).

It should also not be confused with VHF marine although there are specific VHF marine band channels designated for commercial and port usage in the context of marine based businesses and industries.

Common Itinerant and Low Power Business Frequencies

Often heard at construction sites, special events, shopping malls, stores, gas stations, etc. Often supplemented with heavy use of FRS frequencies. Use of all 22 FRS frequencies is permitted by businesses under the FCC rules. Narrowband and low power (2 watts or less) simplex use of any of the 22 FRS frequencies is permitted license free. The old GMRS frequencies are labelled with their original color dot designation even though most users will simply refer to the FRS channel number.

Can businesses use FRS radios? Yes they can under Part 95 of the FCC rules. Only the 5 MURS frequencies and the 22 FRS frequencies may be used without a license, however.

Most of the transmissions you'll hear on these frequencies are from portable handheld radios - walkie-talkies, but sometimes high powered mobile radios or even portable repeaters are heard. Portable or temporary repeater output frequencies may be any of the VHF low or VHF high frequencies. On the UHF band, input frequency is 5 MHz above output frequency. In many situations all frequencies are used for simplex only. The 457 MHz, 462 MHz and 467 MHz frequencies are simplex use only and are often used for on-site communications using portable handheld radios. Several of the itinerant frequencies may be used as repeater output channels, repeater input channels or for simplex/talk-around purposes. Examples include the 464.500 MHz, 464.550 MHz and 469.500 MHz, 469.550 MHz frequencies. 464.550 MHz may be used as a repeater output (paired with 469.550 MHz) or both frequencies may be used for simplex purposes. The 457/467 MHz frequencies are also used by shipboard and dockside repeaters or simplex systems aboard ship (10 MHz offset or 10.225 MHz offset). The itinerant frequencies in the VHF bands do not have a set pairing or offset like the UHF bands do.

Note the Motorola RDX, CLS and XTN series default channels - these are not FRS/GMRS frequencies. Motorola FRS and GMRS radios use the standard 14 or 22 FRS channels. The default channels listed below only apply to Motorola business band radios in the RDX, CLS, XTN and similar series/variants sold in the United States

The default channels / frequencies for most job site / contractor / construction site crews will vary. Many crews use FRS, MURS or CB for on-site communications, especially if multiple contractors and subcontractors are working together on a large site. The default out of the box factory UHF channels are also often heavily used. These include 464.550 MHz, 464.500 MHz, 467.925 MHz, 467.850 MHz, 467.875 MHz, etc. Most radios default to 67.0 Hz CTCSS tone (PL tone - called “code” in many instances). Other popular CTCSS and DCS tones or codes include 77.0 Hz, 88.5 Hz, 100.0 Hz, 203.5 Hz, 250.3 Hz, and the DCS / DPL codes 023, 025, 026, 032, and 754. Patience, a SDR and/or a scanner or frequency counter with CTCSS / DCS decode capability will yield interesting results. In urban areas it is very common to hear multiple users on the same frequency or channel, but with different CTCSS / DCS (PL / DPL) tones and/or codes in use. This is particularly common on the UHF business itinerants, the FRS channels and the MURS channels. Motorola MURS radios default to 154.570 MHz and 154.600 MHz out of the box. Motorola on-site VHF handhelds default to 151.625 MHz and 151.955 MHz out of the box (see list above for all available channels in both the VHF and UHF configurations. UHF is generally more popular in urban areas while VHF is more commonly used for mobile to mobile communications and in rural areas. However, all three bands can and are used in urban areas.

VHF Low Band 25-50 MHz

Note that 30.000 to 87.975 MHz is shared with the SINCGARS VHF FM military land mobile communications system, which operates in either frequency hopping FH mode or single channel SC mode. This is often referred to as "FM" within the military. 30 to 88 MHz in 25 kHz steps. While the military usually stays in the military/government sub-bands (29.80-30.55 MHz, 32-33 MHz, 34-35 MHz, 36-37 MHz, 38-39 MHz, 40-42 MHz, 46.6-47 MHz and 49.6-50 MHz they can also be found in the land mobile sub-bands using 25 kHz steps and 150 Hz CTCSS tone. Military operations in the United States use both FH and SC mode with or without voice encryption. These channels are often referred to as “FM” or “Fox Mike”. For example, 38.500 MHz would be called “FM 38.50” or “38.50 FM”

Under the guidelines of the NTIA, the military may use any frequency within the 30-88 MHz range for training or operational use requirements in the United States, even frequencies outside the standard government/military bands, on a non-interference basis.

Frequencies below 150 MHz may continue to use 20K0F3E or 16K0F3E "wideband" FM mode (also known as 25 kHz bandwidth or 20 kHz bandwidth). In the land mobile / business radio industry the term is often “25 kHz channels” or “25 kHz bandwidth”. VHF low band 25-50 MHz / 29-50 MHz / 30-50 MHz frequencies are not subject to the FCC narrowbanding requirements that are in force for the 150-174 MHz VHF band and 420-470 MHz UHF band. However, some systems may use 12.5 kHz channels 11K3F3E, 11K2F3E or 11K0F3E emissions on these frequencies.

VHF Mid Band 72-76 MHz

Fixed usage only, adjacent channeled with 72/75 MHz remote control frequencies. Part FCC Part 90.35, 72-76 MHz are for OPERATIONAL FIXED use only.

Used for point-to-point links (voice and data), call boxes, telemetry, industrial control purposes, radio clock control, etc. The California Highway Patrol hybrid VHF/UHF/700 MHz system uses 72 MHz and 75 MHz, as well as microwave systems, to link remote receiver sites for its 39/42/44/45 MHz VHF lowband statewide land mobile network. Several other systems in various places nationwide operate similar systems using the mid band for linking remote sites and providing back-haul audio link capability. The 72 MHz frequencies are also heavily used for low power point-to-point data links, for example controlling a GPS-based clock system. These systems generally transmit in the 2-10 watt range and cover schools, college campuses, manufacturing sites, etc.

UHF Band 450-470 MHz

The UHF band follows a standardized repeater pairing system. Mobiles transmit +5 MHz split. For example, a repeater operating on 451.375 MHz has a mobile input of 456.375 MHz. A repeater operating on 461.1125 MHz has a mobile input of 466.1125 MHz. The input frequencies can, and often are, used for simplex operations as well.

UHF-T Band 470-512 MHz

Note: This band is only used in certain areas, and in those areas only certain sections of it are used. 470 MHz to 512 MHz is allocated to UHF TV channels 14-20. In larger urban areas, channels are "borrowed" and re-assigned to land mobile. The FCC has mandated that users vacate these frequencies in the near future as part of the transition to Digital Television (DTV) and the general push towards public safety use of the 700 MHz band. Like the 450-470 MHz band, UHF-T has a standardized split. Instead of 5 MHz, its 3 MHz. For example, a repeater operating on 470.6875 MHz has a mobile input frequency of 473.6875 MHz associated with it. As of 2019, the 470-512 MHz band does not require use of narrowband modulation (NFM, DMR, NXDN, P25, etc) emissions. However, many cities where the UHF-T band is use suffer from extreme land mobile radio channel congestion and therefore use narrowband modes anyway. A good example of this would be the FDNY Fire and EMS dispatch systems on 482 MHz and their associated Motorola Type II trunking system that operates in the 482 MHz and 483 MHz region with the 6.25 kHz channel step.

In some areas, all public safety and a large amount of business radio operates in the 470-512 MHz T-band or TV-band. These cities (and their associated metropolitan areas) include: Boston, MA, Chicago, IL, Cleveland, OH, Dallas/Fort Worth, TX, Detroit, MI, Houston, TX, Los Angeles, CA, Miami, FL, New York, NY/N.E. New Jersey, Philadelphia, PA, San Francisco/Oakland, CA and the Washington-Baltimore metro area.
