What Is The Range Of Radio Frequencies In Wireless Technologies

What is radio frequency.

What is the range of radio frequencies in wireless technologies.

Abstract the purpose of this chapter is to provide an overview and summary of the fundamental. Ieee 802 11a uses 5ghz exclusively. The higher frequency bands in range fr2 are aimed at providing short range very high data rate capability for the 5g radio. 1 low radio frequencies have better penetration hence pass through objects with less attenuation.

Radio frequencies are part of the electromagnetic spectrum. Although many wi fi channels and wi fi bands are normally selected automatically by home wi fi routers for larger wireless lans and systems it is often necessary to plan the frequencies used. Wlan frequency ranges are in the 2 4ghz and 5ghz bands. According to the official bluetooth website bluetooth uses a low power signal with a maximum range of 50 feet with sufficient speed to enable transmission of data.

Thames and class the range of frequencies used are 900 mhz 2 4 ghz 3 6 ghz 4 9 ghz 5 ghz 5 9 ghz and 60 ghz wikipedia contributors 2019. Radio frequency wireless communications wireless network security. The most common legacy wireless standards 802 11b and 802 11g use the 2 4ghz range. They also include frequencies in radar signals and communications.

Any frequency between about nine hertz meaning nine cycles per second and 300 gigahertz meaning 300 billion cycles per second can be considered a radio wave although only frequencies near the middle of this range are used in actual radio broadcasts. Bluetooth technology uses radio waves to communicate between devices. Using many wi fi access points around a large building or area frequency planning is essential so that the best performance can be obtained from the wireless lan. The 2 4ghz and 5ghz frequencies are most commonly used for our day to day wireless communications.

Most of these radio waves have a range of 15 50 feet. Wireless radio frequency are electromagnetic wave frequencies in the range from 3 khz to 300 ghz. It spreads in the range between 3 khz and 300 ghz. Using the 2 4ghz give you a longer range than the 5ghz frequency while using less power.

With 5g wireless technology anticipated to carry much higher speed data the additional bandwidth.
