Spelling: ISM

ISM [1] stands for "Industrial, Scientific and Medical". It refers to
several radio bands left "unlicensed" due to several issues.

The 2.4GHz ISM [2] band is being made available "unlicensed" due to
noise radiated from devices, the most common being microwave ovens.
It's also becoming useful for technologies such as Wireless LANs,
BluetoothBlue tooth, Blue-tooth, Bucktooth, Bluet, Bluets, Blotto, Bluet's, Blowtorch, Blurt, Blurts, Blued, Blether, Bloody, Bloods, Blood's [3], cordless telephones, baby monitors, security
monitoring, and several other applications using spread spectrum [4]
technology.

In Australia, The ACAAC, AVA, AA, CA, AKA, AAA, ACT, ABA, AMA, ADA, ALA, ANA, ARA, ASA, RCA, ACE, AHA, AC'S [5] have allocated the following ISM [6] bands:

* 6.765 MHz to 7 MHz
* 13.41 MHz to 13.57 MHz
* 26.175 MHz to 27.5 MHz (CB-Radio fits within there)
* 39 MHz to 41 MHz
* 902 MHz to 928 MHz (Very common with cordless telephones, and
older WLANLAN, ELAN, WAN, ALAN, KLAN, CLAN, FLAN, PLAN, WEAN technology)
* 2.4 GHzHz, GHQ, MHz, KHz, Z to 2.4835 GHzHz, GHQ, MHz, KHz, Z (Sometimes called "_The_ ISM [7] Band")
* 5.725 GHzHz, GHQ, MHz, KHz, Z to 5.83 GHzHz, GHQ, MHz, KHz, Z
* 24.05 GHzHz, GHQ, MHz, KHz, Z to 24.25 GHzHz, GHQ, MHz, KHz, Z
* 59.3 GHzHz, GHQ, MHz, KHz, Z to 64 GHzHz, GHQ, MHz, KHz, Z
* 122.25 GHzHz, GHQ, MHz, KHz, Z to 123 GHzHz, GHQ, MHz, KHz, Z
* 241 GHzHz, GHQ, MHz, KHz, Z to 248 GHzHz, GHQ, MHz, KHz, Z

(Note: I must admit some of these frequencies aren't accurate. Check
the ACAAC, AVA, AA, CA, AKA, AAA, ACT, ABA, AMA, ADA, ALA, ANA, ARA, ASA, RCA, ACE, AHA, AC'S [8]'s website for more information)
