• 802.11a5GHz, 54Mbps throughput, OFDM modulation

• 802.11g2.4GHz, 54Mbps throughput, OFDM modulation

Comparative Signal Rangesby Standard

Understanding 802.11n• Amendments to the previous 802.11 standard• Significant improvement to PHY layer transmission rate:

Forward Error CorrectingChannel bonding (20/40 MHz)Shorter GI (800/400 ns)Spatial multiplexing

• Increase the MAC layer transfer rate to achieve over100 Mbps data throughput

• MCS selected based on RF channel condition based on8 data rates, bonded channels, multiple spatial streams,guard intervals, and modulation types

MIMO (Multiple-In/Multiple Out)

Commonly referred to as smart antennatechnology

Sensitivity to fading is reduced by the spatialdiversity provided by multiple spatial paths.

Can provide better range in environmentswith multi-path issues

What About Range?Facts:“Under the best conditions, many 802.11n routers deliver

throughput between 100 Mbps and 120 Mbps near therouter. However, speeds degrade quickly to about 45Mbps in the 300- to 600-foot range”

“The truth about the 802.11n specification is that it does notreally increase your wireless coverage area.”

The same RF physics still apply, so the wireless connectionwill still drop out at the same signal levels.

Transmit Power• Tx power is the amount of power a radio transmits

• Generally, the longer the distance, the more powerneeded

• High transmit power and receive sensitivity means:

greater coverage area with less access pointsor

long distance point-to-point links

Understanding dBm

The dBm is an absolute power measurement. “m” stands for milliwatt,which is the reference point.

0dbm is 1mW of power

1dbm is 1dB stronger than 0dBm or 1dB stronger than 1mW (1.3mW)-x dBm is power less than 1mW

0dBm = 1mW -3dBm = 0.5mW3dBm = 2mW 10dBm = 10mW -10dBm = 0.1mW

28dBm = 600mW (approx.) 30dBm = 1000mW or 1 wattDbm is

dBm to Milliwatts

Understanding 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 istransmitted like a globe, equally in all directions.

• Does not exist in real life. The design of any real antenna willcause the signal to favor one direction (even slightly) over another

• The physical laws of the conservation of energy says if you gainpower in one direction, the other direction must be lost.

• To have antenna gain therefore means the signal pattern ischanged to be favorable in a certain direction over another. Themore disproportional it is, the more gain is realized.

Calculating EIRP• Dbm and Dbi – You can add or subtract them!

• Dbm is power while Dbi is antenna gain.

• The total power (transmitter, losses of cable, gain of antenna etc.) is calledEIRP (Equivalent Isotropically Radiated Power)

• Example: 28dbm + (-2db coax loss) + 6dbi antenna = 34dbm EIRP.

• FCC limits EIRP for Omni-directional signals to 36dbm for 2.4GHz and 5GHzWiFi

• For directional signals, for every 3db of antenna gain beyond 6dbi, transmitterpower must be reduced by 1dbm.

26dbm +6dbi = 32dbm EIRP

Up to 600mW Tx Power N Mode• The typical leading brand AP has a Tx power of 17dBm or 50mW
