New systems operate at 900-1000 MHz?

Frequencies around 0.9 GHz sit in the UHF region and are a practical choice for modern wireless systems because they strike a good balance between antenna size, propagation, and available spectrum. At 900–1000 MHz, antennas can be reasonably compact, and the signals propagate well enough to cover urban and campus-sized areas without needing excessive infrastructure. There’s typically enough spectrum in this band to support multiple channels and higher data rates than the lower bands, making it a common target for new wireless links. The lower bands shown, while they offer strong diffraction and building penetration, generally have less spectrum available for new high-capacity services and often require larger antennas or denser infrastructure to achieve comparable performance. Hence, 900–1000 MHz is the best fit for new systems.
