Introduction to 5G frequency ranges (FR1 and FR2)

The NIST frequency division of 5G spectrum into FR1 and FR2 will avoid interference issues with existing networks. Regardless of the standard that is ultimately selected, there are likely to be a variety of carriers deployed across different geographical regions, so bands may not be universally used. Therefore, it is important to ensure that any new frequency bands follow guidelines that will make it easy for users to access them without interference. This will ensure continuity in service and allow operators to use the available spectrum efficiently without any unexpected interference issues. In this way, many developers can work on using these frequencies in different ways such as development of new radio technology. The FR1 and FR2 5G frequency bands are primary wideband 5G unlicensed frequencies that provide air interface options to support the spectrum requirements of 5GNR services. FR1 and FR2 offer a wide range of spectrum needs with both large blocks of contiguous license-free spectrum and smaller bands that require coordination in certain geographical areas. 5G frequency or FR1 (First Radio Frequency) is defined as downlink 150 MHz to 7650 MHz, uplink from 2300 MHz to 29250 MHz. This spectrum has been identified by 3GPP for the initial deployment of 5G NR. The FR1 frequency range is currently in use. The FR2 range is between 28 GHz and 29 GHz, encompassing the millimeter wave band. From a technical perspective, both bands require a different antenna and frequency modulators/demodulators than what was used for 4G/LTE. The FR1 frequency band is the umbrella name for three specific frequency bands: 2,300 MHz (Band 30), 2,600 MHz and 3,400 MHz. The 5G frequency range is between 24 GHz and 100 GHz, which means that it covers a much greater range of frequencies than current 4G (1.4 GHz to 2.5 GHz) and 3G (850 MHz to 2,600 MHz) cellular networks.

Introduction to 5G spectrum

This increased frequency range will allow 5G to provide faster data speeds, more reliable connections, and an enhanced experience for devices compared with previous cellular technologies. 5G Frequency (FR1, FR2) is the basis of any real-time data streaming, voice and video services. 5G Frequency (FR1 and Fr2) is a dual band WiFi AC router which uses the brand new 5G technology, offering up to 2x faster connection speed, 1.7Gbps dual band WiFi speed, next generation hardware firewall and self-defense technologies, providing you with a reliable and fast internet experience. The term 5G frequency refers to frequency division multiplex (FDM) of the existing bands.

Introduction to mmwave bands

The existing 4G/LTE uses FDM spectrum based on 5 MHz radio spectrum, while 5G proposes to use the bandwidth between 10 MHz and 100 MHz (FR1) and between 1 GHz and 10 GHz (FR2). 5G frequency will have three frequency ranges FR1, FR2 and FR3. The 5G Base Station shall be operated at 24 GHz to supplement 4G networks with higher data transmission rates on a broad scale and is expected to cover large areas. The harmonized band 5G frequency encompasses two frequency ranges: the so-called FR1 band, which is seen as an intermediate step towards 5G systems, and the FR2 band, which will replace the current 3G/4G bands. FR1 and FR2 Frequency Range: The FR1 and FR2 frequency bands are reserved for IoT applications. This band has therefore been allocated with a different set of operating rules than those governing most services in connected, mobile and urban settings. In other words, the potential of this band will be explored beyond the traditional cellular-based 5G NR deployments.
