A process used to determine the number and placement of access points (AP) that provides adequate coverage throughout the facility. With wireless systems, it’s difficult to predict the propagation of radio waves and detect the presence of interfering signals without the use of test equipment. As a result, it’s often necessary to perform a RF site survey to fully understand the behavior of radio waves within a facility before installing wireless network access points.
The ultimate goal of a RF site survey is to supply enough information to determine the number and placement of access points that provides adequate coverage throughout the facility. In most implementations, adequate coverage means support of a minimum data rate. A RF site survey also detects the presence of interference coming from other sources that could degrade the performance of the wireless LAN.

- RF tag
In an RFID system the transponder that contains the data to be transmitted is called an RF tag. RF tags are either active or passive.
Short for Radio Guide, RG is a designation for different types of coaxial cable, which is a type of wire that consists of a center wire surrounded by insulation and then a grounded shield of braided wire. The RG specification is a older military-initiated specification. RG-6 is one of the most commonly used coaxial cables […]
- RGB monitor
Short for red, green, blue monitor, a monitor that requires separate signals for each of the three colors. This differs from color televisions, for example, which use composite video signals, in which all the colors are mixed together. All color computer monitors are RGB monitors. An RGB monitor consists of a vacuum tube with three […]
Acronym for Right-Hand Side Blacklist. A type of DNSBL that uses domain names instead of IP addresses.
RIFF is a file structure for multimedia resource files, it is not a file format but rather the structure that defines the class of more specific file formats, such as WAV and AVI. The RIFF format specifications were first developed by IBM and Microsoft, and published by in 1991 in “Microsoft Windows Multimedia Programmer’s Reference”. […]
