Legal Power Output by Country

Is there a resource that lists the legal power output (mW) of an Access
Point, by country?

I'll start the ball rolling.
Australia follows

Frequency Band (MHz)
Maximum Equivalent Isotropically Radiated Power (EIRP)

915 to 928
1 watt

2400 to 2483.5
4 watts
(devices other than frequency hopping devices with a bandwidth greater
than 1 MHz)

2400 to 2483.5
500 milliwatts
(frequency hopping devices with a bandwidth greater than 1 MHz)

5725 to 5875
1 watt

I'm talking about consumer use of 802.11g, for example. Surely the output
levels you quoted are for special use, because they seem way high to be
legal. These would be considered multiple times over what the FCC allows in
the US.

IIRC the US is based on EIRP (Effective Radiated Power) which takes into
account the loss of the coax and the gain of the antenna rather than a pure
wattage figure - not sure what the maximum EIRP is here in the US though.

I believe you can find maximum EIRP tables in the 802.11 standard on the
IEEE.org web-site, as well as on the Cisco web-site.

In the USA it depends on whether one is using a directional antenna or an
omni. For an omni the max EIRP is 1 watt.

For North America, the 802.11b/g standards state limits of 1 watt, for
Europe 100 mW. Transmitters capable of more than 100 mW are required by the
standard to provide the ability to limit the power to 100 mW or less.

Anyone know the maximum EIRP in the USA for directional antenna on
802.11a/b/g devices?

I doubt that very much AFAIK the max in the US is also 100 mw!

I believe 1W is the maximum output the FCC allows on the 2.4ghz band. You
can find legal high-power equipment easily online such as
http://www.netgate.com or http://www.rflinx.com

From IEEE Std 802.11b-1999, clauses 18.4.7.1, 18,4,7,2m and table 115:

"The maximum allowable output power, as measured in accordance with
practices specified by the appropriate regulatory bodies, is shown in Table
115. In the USA, the radiated emissions should also conform with the ANSI
uncontrolled radiation emission standards (IEEE Std C95.1-1999).

Table 115-Transmit power levels
Maximum output power | Geographic location | Compliance document
1000 mW | USA | FCC 15.247

100 mW (EIRP) | Europe | ETS 300-328

10 mW/MHz | Japan | MPT ordinance for Regulating Radio Equip

18.4.7.2 Transmit power level control

Power control shall be provided for transmitted power greater than 100 mW. A
maximum of four power levels

may be provided. As a minimum, a radio capable of transmission greater than
100 mW shall be capable

of switching power back to 100 mW or less."


Most commodity devices are 100 mW (typically a lot less). For one thing, it
permits the same hardware to be sold in North America and Europe. For
another thing, if you put more than 100 mW into a laptop adapter, it gets a
lot harder to comply with the ANSI radiation requirements, which specify
maximum human exposure times for various power densities, as a function of
frequency.

According to http://www.wi-fiplanet.com/tutorials/article.php/1428941, if
the antenna is less than 6 dBi (omni) then the EIRP may be 1 watt. If the
antenna is 6 dBi or greater (directional) then the EIRP may be 4 watts.
Page 233 of the 802.11 spec confirms the first, and
http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_installation_and_configuration_guide_chapter09186a0080101c27.html
confirms the latter.
