The 900 MHz radio system is at a lower frequency and will penetrate surfaces more easily ; while 2.4 GHz systems are more reflective and tend to be affected more by buildings, foliage or moisture that can attenuate the signal.
Read moreWhat is the difference between 900 MHz and 2.4 GHz?
Higher frequencies can use less power, but will reflect off of dense surfaces. The 900MHz radio system is at a lower frequency and will penetrate surfaces more easily . Tempest 2.4GHz systems are more reflective and tend to be affected more by bodies, foliage, or moisture that can attenuate the signal.

Read moreWhat is ISM band why it is free?
The industrial, scientific, and medical radio band (ISM band) refers to a group of radio bands or parts of the radio spectrum that are internationally reserved for the use of radio frequency (RF) energy intended for scientific, medical and industrial requirements rather than for communications.
Read moreWhat can interfere with 868mhz?
868 MHz interference Systems that use the 868 MHz-band (868–870 MHz), for example, thermostats, fire systems, burglar systems, and DIN-transceivers may have difficulty communicating when there is a strong 800 MHz broadband transmitter nearby.
Read moreWhat uses 433MHz frequency?
433MHz is a commonly used frequency band for all types of equipment that require little power, such as garage door openers, headphones, baby phones and remote controls . Also many inexpensive transmitters and receivers for switching devices and light dimmers operate on the 433MHz band.
Read moreHow far can 900 MHz travel?
The lower frequency radio waves of 900 MHz radios provide greater penetration through walls, trees and other obstacles, making it optimal for most non-line-of-sight applications. A typical AW900xTR Radio using high powered AW-15 15dbi antenna can go distances of up to 1500 feet with buildings and/or trees in the way.
