X Band
Developed during the 1950s and in use since about 1965. X Band ranges between 10.5 and 10.55 GHz (10.525 with a tolerance of 0.025), compared to other bands it has low frequency and high output. This makes it particularly easy to detect, in fact it is possible to detect at up to 4 miles away although it's own useful range is obviously a lot less than this. Unfortunately because intrusion alarms, radio masts, and door openers use a similar signal these can be the cause of a lot of false alarms.
K Band
This came into use in 1976-8 firstly for mobile units and uses 24.150 plus or minus 100 MHz (to give 24.050 to 24.250 GHz), or 24.125 plus or minus 100MHz (to give 24.025 to 24.225 GHz). Because water will absorb wavelengths around 22.24 GHz it can be absorbed more easily by water in the atmosphere so a rainy day may give a weaker signal. K Band can be detected anything upto 2 miles away on a good clear day. Traffic light sensors and some automatic door openers use K Band transmitters so a false alarm may result when approaching these devices.
Ka Band / Ka WideBand
Came into force in 1983-7 and uses 34.2-35.2 GHz, Ka Wide Band detection range is upto 1/2 mile.
Ka Super Wide Band
1992 Developed from Ka Wideband, Superwide Band can use any frequency between 33.4-36.0 GHz.
Ku Band
13.45 GHz
Laser
904 nM
A mobile unit the laser gun can pinpoint a target in a lane of traffic, it takes less than half a second to get a reading wheras a radar can take 2-3 seconds. It can't be used from behind glass, requires a very steady hand, and at 1000 feet the beam is 3 feet wide, at 1 and 1/2 miles the beam is 2 lanes wide.

Hand held radar guns. K Band radar
Gatso cameras = K Band radar
Hand held or tripod mounted Pro Laser 2, LTI 20/20 laser gun = Laser
Mini Gatso cameras = K Band radar
X band is used for automatic doors, security systems, etc....
