NB-IoT . NB-LTE stands for Narrow Band LTE. For the high level description of NB-LTE and some comparative view of other technology, refer to LTE-M/Category M/M1/M2 page. By Criterion RX Band Noise As mentioned above, the transmitter power amplifier (PA) amplies both the desired transmitter (Tx) signal as well as the noise over a wide frequency range[1]. PA Transceiver Especially, Band12 is the worst case because its duplex spacing(30 MHz) and band gap(12 MHz) are extremely narrow[8].

Coverage Area (-100 dBm) There are 22 CA configurations recorded for this LTE frequency band. Currently the LTE bands between 1 & 22 are for paired spectrum, i.e. FDD, and LTE bands between 33 & 41 are for unpaired spectrum, i.e. TDD. FDD LTE frequency band allocations There is a large number of allocations or radio spectrum that has been reserved for FDD, frequency division duplex, LTE use.

IMT-E (Duplex Spacing) 2570 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 LTE TDD frequency bands, corresponding devices capable of operating in those bands, and antennas tuned to those bands.
The reasons that network operators deploy 1800MHz LTE network are obvious: good coverage, and the

Difference 5G NR and 4G LTE. 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. With SATELLINE-EASy product family products, including the previously mentioned models, the RF frequency can be set in 6.25 kHz steps @ 12.5 kHz and @ 25 kHz channel spacing (width). @ 20kHz channel spacing (width) the frequency step is 10 kHz.

LTE also supports both frequency division duplex (FDD) and time division duplex (TDD). 3. Wide range of terminals – in addition to mobile phones and MiFi`s, many consumer electronic or M2M devices incorporate LTE embedded modules. 4. Mobility and coverage - LTE supports handover and roaming to existing mobile networks.
