FCC Narrowbanding Mandate

Current Use
421–512 MHz FCC Narrowband Mandate for PLMR and Industrial/Business Radio Pool systems
The FCC has mandated that all Private Land Mobile Radio (PLMR) and Industrial/Business Radio Pool systems operating in the 150-174 and 421-512 MHz bands must operate using a channel bandwidth of no more than 12.5 kHz, or "a technology that achieves the narrowband equivalent of one channel per 12.5 kHz of channel bandwidth (voice) or 4800 bits per second per 6.25 kHz (data) if the bandwidth for transmissions specified in the modification application is greater than 12.5 kHz."

The deadline for narrowbanding is January 1, 2013. Prior to this date, systems in these bands were allowed up to 25 kHz channel bandwidth.

Narrowbanding of the 470-512 MHz portion ("T-band") has been put on hold by the FCC. Congressional action in the Middle Class Tax Relief and Jobs Creation Act mandated that this sub-band be cleared of all mobile systems in light of the TV band incentive auction and the eventual creation of the nationwide public safety broadband network.

2019 World Radiocommunication Conference (WRC-19) Agenda Item 1.3

Proposed Use
460–470 MHz WRC-19 Agenda Item 1.3
1.3 to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 [COM6/8] (WRC-15);

3GPP 4G/5G Bands

Current Use
460–465 MHz 3GPP 4G LTE FDD band 73 Downlink (China) 461–466 MHz 3GPP 4G LTE FDD band 72 Downlink (Europe) 462.5–467.5 MHz 3GPP 4G LTE FDD band 31 Downlink (Brazil)
3GPP is the global standards organization for 4G LTE and 5G NR radio technologies. It designates multiple bands throughout the radio spectrum for 4G/5G use. Different combinations of bands are used in different countries and regions.

Bands designated with a "B" are standardized for 4G LTE; bands designated with an "N" are 5G. Some bands are designated for both.

Frequency Division Duplex (FDD) uses paired bands, where one band is used for downlink (DL) transmissions from the base station to the user terminal (i.e., handset), and the other band is used for uplink (UL) transmissions from the user terminal to the base station.

Time Division Duplex (TDD) uses the same band for both uplink and downlink, which share the same frequency in time over ~millisecond timescales.

WRC-19 Agenda Item 1.3

Proposed Use
460–470 MHz WRC-19 Agenda Item 1.3
"to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution COM6/8 (WRC 15)"

Standard LTE Bands

Current Use
462.5–467.5 MHz LTE band 31 FDD downlink
The following bands have been defined by 3GPP as standard LTE bands for Frequency Division Duplex (FDD, where mobile and base stations transmit in separate bands) and Time Division Duplex (TDD, where mobiles and bases transmit and receive on the same frequency). These bands are defined in 3GPP TS 36.101 (link below).

Note that bands 15 & 16 and 30-32 are not defined, and the FDD band 29 is used for downlink-only for carrier aggregation, so it has no corresponding uplink band.

Uplinks refer to the frequencies used for handsets and other user devices to transmit to the base station, and downlinks refer to frequencies used by base stations to transmit to the user devices.
