lte band uplink (mhz) downlink (mhz) width of band (mhz) duplex spacing (mhz) band gap: 1: 1920 Various LTE definitions must be examined when designing a universal global mobile device. The global UMTS bands are clear as Band 1, 8 or Band 2, 5, but LTE bands are much more complex. Band 3 is reportedly the most widely used band for LTE deployment. The reasons that network operators deploy 1800MHz LTE network are obvious: good coverage, and the Rules of Thumb for Duplex Filters • Avoid Bandwidth > 4% of center frequency –At 600MHz, like to keep filter bandwidth <24MHz Rules of Thumb for Duplex Filters • Avoid Duplex gap < 1% –7MHz gap at 700MHz, 26MHz gap at 2.6GHz • Figure of Merit (bandwidth/duplex gap) < 4 • Distance to nearest interfererDistance to nearest interferer Do you want to use 2 external antennas for LTE and need space diversity?

The studies of 5G NR (New Radio) in 3GPP started in 2015 and later became the first NR specifications in Release 15 in 2018 focusing on the use cases eMBB (enhanced Mobile Broadband) and URLLC (Ultra-Reliable and Low Latency Communication). channel spacing (width) options, @ 12.5kHz, @ 25 kHz and @ 150 kHz.

Channel spacing is the distance between center frequencies of two adjacent component carriers for intra-band contiguous carrier aggregation. The channel spacing between the center frequencies of contiguously aggregated component carriers is a multiple of 300 KHz, in order to be compatible with the 100 KHz frequency raster of LTE Rel-8 and to preserve orthogonality of the subcarriers with 15 Subcarrier Spacing and OFDM Symbol Duration.

LTE Band 21: This “1500 MHz” band is identified by 3GPP as a Japanese band, but it is allocated globally to the mobile service on a “co-primary basis”. LTE FDD Frequency Bands March 2014 • There is a lot of overlap between band definitions for regional reasons • The Duplex spacing varies from 30 MHz to 799 MHz • The gap between downlink and uplink varies from 5 MHz to 680 MHz • Narrow duplex spacing and gaps make it hard to design filters to prevent the Duplex Spacing (MHz) 45.
