Freewave FGR3

Filter

Freewave FGR3 radios represent some of the most dependable and versatile wireless communication devices servicing industry and business. They are backward compatible with the FGR2, FGR and DGR series of FreeWave serial radios, enabling customers to leverage and extend their existing investment. They are a cost effective solution and a great choice for connectivity to serial devices in the most demanding applications.

When it comes to satisfying long-range data transmission requirements in industrial and commercial environments, these 900 MHz ISM band-based radios hit the mark with ease. When these radios have a clear line-of-sight to operate in, they prove to be a highly effective way to get various kinds of data from point A to point B easily.

The Freewave FGR3 radio stands out for its capacity to support three types of network structures: point-to-point, point-to-multipoint, and mesh. The Freewave FGR3 can handle both lines of sight (up to 25 miles in certain circumstances) and non-line-of-sight situations (supplement directories increased service territories beyond what was previously possible).

More Information about Freewave FGR3 Radios

VHF radios (like FGR3) are deemed suitable for providing high-data-rate services because they can operate at a line of sight range, carrying plenty of megabits' worth of information useful for many evolving industrial control and automation applications—especially when combined with some sort of error-correcting code. In this context, "VHF" refers to radio waves with frequencies between 30 and 300 megahertz. Since VHF signals travel in a straight line (line of sight), they're less prone to interference or multipath distortion than UHF signals. That makes them more reliable—something you really want if your system can't afford to drop packet bursts during normal operation or under stress conditions.

Reliability is another extremely important attribute of Freewave FGR3 radios. They are built to operate in the face of unusual environmental conditions, such as those associated with outdoor and industrial settings — a lot of rain and/or snow, for instance, or very high temperatures.

Meeting today's high-security demands, the Freewave FGR3 radio offers multiple layers of encryption and strong authentication that protect all data transmitted via the radio from being accessed or tampered with by unauthorized persons. This is especially important for critical infrastructure applications where maintaining the integrity and confidentiality of the data is absolutely essential.

Common Reasons That Cause Radio Communication Failure

Radio communication is one of the most common ways to transmit data from one location to another, especially in situations where the distance between the two locations becomes too far to use some type of transmission wire. Because using industrial radios is so common, it is not unusual to encounter different problems when trying to communicate with different locations. Here are some of the most common reasons that communication issues may occur:

Configuration of the Radio

There are different configuration settings depending on the type of radio being used. For instance, is it an Ethernet radio or a serial radio. Other configuration settings that can potentially cause issues might be related to security settings on the radio, whether it is a master or slave radio, frequency range and many other factors.

Radio Frequency Impairments

One of the of the most common impairment issues is Electromagnetic Interference (EMI). EMI is generated from non-radio equipment operating near radio communication hardware. The electromagnetic field generated from this equipment can have a negative impact on the reception and transmission of radio signals. Another source of frequency impairment is improper cable selection, which can degrade the signal or possibly limit the power of the radio signal.

Improper Installation Methods

Improper installation of radios and antennas can lead to communication failure. Common installation mistakes include: loose cable connections, installation of damaged cables, running data cables in line with power cables and many other issues. When installing antennas, it is important to make sure that there is good line of sight and to limit or eliminate any potential obstructions that could cause communication failure.
