RFS’ white paper discusses the architectural differences between an antenna that has been designed for MIMO performance and one that has been optimized for beamforming. It will explain why antenna characteristics that are desirable for MIMO will result in a degradation of the beamforming ability of the antenna.
byChuck Powell, RFS Meriden
MIMO (Multiple Input Multiple Output) antennas operate by breaking high data rate signals into multiple lower data rate signals in Tx mode that are recombined at the receiver. Beamforming arrays are inherently different from MIMO in that the multiple columns of dipoles work together to create a single high gain signal. While both techniques work well, an antenna optimized for one method, does not work well for the other. Compromise geometries exist, but the user is sacrificing the performance of the system in order to save money on the relatively inexpensive antenna.
RFS’ white paper discusses the architectural differences between an antenna that has been designed for MIMO performance and one that has been optimized for beamforming. It will explain why antenna characteristics that are desirable for MIMO will result in a degradation of the beamforming ability of the antenna.
The paper will also talk about the differences of beamforming antennas that are used in active and passive systems.

What is the RF link in networking? ›
The RF link is between a transmit antenna and a receive antenna. Sometimes the RF link includes the antenna and sometimes it does not, this will be clear from the context, but usually it includes the antennas. The principle source of link loss is the spreading out of the EM field as it propagates.
How does RF wireless work? ›
Wireless transmissions are made up of radio frequency signals, or RF signals, which travel using a variety of movement behaviors (also called propagation behaviors). RF communication starts when radio waves are generated from an RF transmitter and picked up, or “heard” by a receiver at another location.
How does RF communication work? ›
The initial communication in an RF connection for the internet starts when the radio frequency transmitter generates radio waves, and the receiver hears it on the other end. The transmitter also modifies these signals through modulation techniques to convert the data into signals.
What is RF in the internet? ›
A radio frequency (RF) signal refers to a wireless electromagnetic signal used as a form of communication, if one is discussing wireless electronics.
What are the three types of network links? ›
LAN (Local Area Network) MAN (Metropolitan Area Network) WAN (Wide Area Network)
Is RF the same as Wi-Fi? ›
Is WiFi the same as radio waves? Wi-Fi is a set of standards for local area network communications that makes use of radio frequencies - but not FM radio frequencies. The modulation and coding differs substantially from FM radio as well, as Wi-Fi trades coverage range for higher data throughput.
Is Bluetooth an RF signal? ›
RF can go through and there is no need to point your remote to the device, as it does not require to be in line-of-sight. Bluetooth (which is a type of RF) is a wireless communication technology that uses radio waves of a specific frequency to transmit data from one device to another over short distances of up to 10 m.
Why RF is better than Wi-Fi? ›
Radio frequencies can be unique so not to interfere with other wireless equipment. Using a separate radio frequency does not interfere with existing Wi-Fi bandwidth. The use of a unique radio frequency for a system reduces the need for IT involvement.
Is RF wireless better than Bluetooth? ›
However, unlike Bluetooth, RF headphones can transmit audio through solid objects or walls. It can work with minimal audio compression. This means superior sound quality and much shorter latency or delay.
The frequency of radio waves ranges from 3 kHz to 300 GHz. Their wavelengths, as measured from the peak of one wave to the peak of the next, range from 1 millimeter (0.4 inch) to 100 kilometers (62 miles). These waves travel at the speed of light.
What two devices use RF to communicate? ›
Examples include: wireless garage door openers, wireless microphones, RF universal remote control devices, cordless telephones, wireless alarm systems, Wi-Fi transmitters, and Bluetooth radio devices.
How can we generate RF signal? ›
Many RF signal generators rely on the electrostriction (or inverse piezoelectricity) property of crystalline quartz as a reference oscillator (also known as an XO) to produce a reference frequency. Its stability will ensure that the frequency output of the source remains accurate between calibrations.
What is the RF for 5G? ›
The primary technologies include: Millimeter wave bands (26, 28, 38, and 60 GHz) are 5G and offer performance as high as 20 gigabits per second ; Massive MIMO (Multiple Input Multiple Output – 64-256 antennas) offers performance “up to ten times current 4G networks;” “Low-band 5G” and “Mid-band 5G” use frequencies from ...
What are the RF wireless devices? ›
RF Wireless products include antennas, RF Antennas, Cables, Capacitors, Relays, Transistors, and more that operate over the entire spectrum of frequencies and all wireless networks including Bluetooth, Wi-Fi, ZigBee, Mesh Networks, LTE, WiMAX, and ISM band protocols.
How to read radio frequency? ›
How radio frequency works. Radio frequency is measured in units called hertz (Hz), which represent the number of cycles per second when a radio wave is transmitted. One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second.
What is RF on my router? ›
Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz).
What is the meaning of RF in router? ›
The technique of guiding radio frequency signals from one place to another inside a network or system is referred to as RF routing, also known as Radio Frequency routing, according to Broadbandsearch. Through a number of channels or routing methods, RF signals are transmitted and received.
What is RF on a modem? ›
Radio frequency modems, also called “RF modems” and “wireless data modems”, power an impressive array of industrial functions. RF wireless systems enable mining companies to work in remote areas. RF modems perform critical tasks for water supply and sewerage systems.
What RF does Wi-Fi use? ›
Wi-Fi uses radio waves to transmit information between your device and a router via frequencies. Two radio-wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz.
