Meaning
Frequency spectrum allocation in the 800 megahertz range typically deployed for machine to machine communication across European territories. Many network operators favor lte-m band 20 for its combination of data throughput and geographical reach. This band provides a primary resource for low power wide area networks.
It is limited to specific regions and is not available for use in North American or Asian markets.
Propagation Benefit
Low frequency signals in the 800 megahertz range travel further and penetrate obstacles better than higher frequency bands. This characteristic makes lte-m band 20 ideal for connecting devices located deep inside buildings or in rural areas. The increased coverage reduces the number of base stations required to support a large number of sensors.
Spectrum Ownership
National regulators auction off the rights to use these frequencies to specific mobile operators. Because lte-m band 20 is a licensed resource, the risk of interference from other devices is minimal. This provides a reliable and secure environment for critical infrastructure and industrial monitoring.
Antenna Design
The wavelength of the 800 megahertz signal requires an antenna that is physically larger than those used for 2.4 gigahertz systems. Designers must carefully integrate the antenna into the device enclosure to maintain efficiency without increasing the overall size. Proper tuning is essential to achieve the maximum possible range.
