Lbanden
L-band is a portion of the microwave radio spectrum spanning roughly 1 to 2 GHz. In practice, many references consider 1.0–2.0 GHz, though exact allocations vary by region. The band lies above VHF/UHF and below higher-frequency bands, offering a balance of moderate bandwidth and favorable propagation characteristics, including relatively low atmospheric attenuation compared with higher frequencies and compact antenna sizes.
Applications of L-band are broad. It is widely used for satellite communications, including mobile satellite services
Earth observation uses also include synthetic aperture radar (SAR) systems operating in L-band, such as ALOS
Propagation and performance characteristics of L-band lend themselves to reliable outdoor and mobility applications, though spectrum
