(Law of diminishing return). • “If you increase power from 1,000,000 watts to 2,000,000 watts, or if you change power 1 watt to 2 watts, in either case the perceived signal increase will be +3db.” • The other reason to use Db is that we need the “units” to be the same (dbm, dbi etc.) • Db is a comparison from one to another, not a measurement of power itself. •Easy way to convert… • 14 Power increase of 2x = +3db Power decrease of half (1/2) = -3db • Power increase of 10x = +10db Power decrease 1/10th = -10db • Power increase of 4x = +6db Power increase 8x = +9db RF 101 – The “Dbm” • The Dbm is an absolute power measurement. • The “m” stands for milli-watt, which is the reference point. • 0dbm is 1mW of power • 1dbm is 1db stronger than 0dbm or 1db stronger than 1mW (1.3mW) • -xdbm is power less than 1mW • 0dbm = 1mW -3dbm = 0.5mW 3dbm = 2mW 10dbm = 10mW -10dbm = 0.1mW • 28dbm = 600mW (approx.) 30dbm = 1000mW or 1 watt • 60dbm = 1,000,000mW or 1000 watts 15 • -80dbm = 0.00000001mW or 10 billionth of a watt. RF 101 – The “Dbm” 16 RF 101 – The “Dbm” 17 RF 101 – The “Dbi” • Dbi = The Db gain an antenna has as compared to a baseline “Isotropic radiator” type antenna. It’s simply a reference point. • The Isotropic radiator is a theoretical antenna where the signal is transmitted like a globe, equally in all directions. • Does not exist in real life. The design of any real antenna will cause the signal to favor one direction (even slightly) over another. • The physical laws of the conservation of energy says if you gain power in one direction, the other direction must be lost. • To have antenna gain therefore means the signal pattern is changed to be 18 favorable in a certain direction over another. The more disproportional it is, the more gain is realized. RF 101 – Dbm and Dbi used together (EIRP) • Dbm and Dbi – You can add or subtract them! • Dbm is power while Dbi is antenna gain. They are both units in “Db”. Same units can be added or subtracted very easily! • The total power (transmitter, losses of cable, gain of antenna etc.) is called EIRP (Equivalent Isotropically Radiated Power) • Example: 28dbm + (-2db coax loss) + 6dbi antenna = 34dbm EIRP. • FCC limits EIRP for Omni-directional signals to 36dbm for the 900MHz ISM band (our phones!) as well as 2.4GHz and 5GHz WiFi (our Datacom) • For directional signals, for every 3db of antenna gain beyond 6dbi, transmitter power must be reduced by 1dbm. • 30dbm +6dbi = 36dbm EIRP 29dbm +9dbi = 38dbm EIRP • 28dbm +12dbi = 40dbm EIRP 27dbm + 15dbi = 42dbm EIRP 19 RF 101 – General Rules of Coverage • General Rules of RF regarding Range: • An increase of 6db in an open area will double the coverage area. • Halving the frequency will double the range. • An increase of 9db in a typical indoor environment will double your coverage area. • Typical indoor meaning a house. In an area with lots of metal, this may increase to 20db or more. •** These generalities are specific to frequencies between 400MHz and 5GHz. 20 RF 101 – An Estimated db Loss chart for 2.4GHz. attenuation at 900MHz is typically 30-50% less (better) 21 Note, RF 101 – Typical Attenuation at 900MHz RF Barrier 22 Timber Plastic Drywall Asbestos Glass Water Brick Marble Paper Concrete Bulletproof Metal Relative decline 1-4db 1-4db 1-4db 1-4db 1-4db 5-8db 5-8db 5-8db 10db 10db 10db 20-25db Example Office wall Wall Office wall Ceiling Window Water tank Wall Wall Wall paper Floor and wall Safety compartment Building (no windows) RF 101 – How much signal do you have to play with? • Our receiver is good for as low as -110dbm. • Link reliability is proportional to signal margin (SNR): • 30db margin = Voice Quality: Excellent. Link Reliability: 99%. • 20db margin = Voice Quality: Good. Link Reliability: 95% • 15db margin = Voice Quality: Fair. Link Reliability: 90% • Note: 23
