Spectrum is a precious, critical resource. Today’s 5G mobile network operators use multiple spectrum ranges to meet specific network objectives. Low-band spectrum provides a good blanket of 5G coverage, while the high-band spectrum, also known as millimeter wave, delivers incredibly fast (lightning-fast) speeds due to the abundance of availiable bandwidth in hundreds of MHz. Unfortunately, a single cell operating in one of these bands can meet one of the objectives – speed or coverage, but not both. When working in lower frequencies, the cell provides expansive coverage at rates like those of current 4G LTE, but with higher performance, like lower latency between the user and radio than LTE. When functioning in high-frequencies, a cell offers very high data speeds over a much smaller coverage area.
Network operators are eager for the regulatory bodies to make mid-band frequencies available for 5G operations, as they offer efficiencies and benefits that allow mobile network operators to improve the experiences of their users. While networks in North America are leading in high-band and low-band 5G deployments, mid-band 5G deployments have only begun with one operator in 2.5GHz. Most recently, the FCC announced plans to auction mid-band spectrum called “C-Band” that will balance speed and coverage in 5G networks.
