Security Systems DCN Wireless Demonstration Guidelines 23.Jan.07 General Information about the DCN Wireless Technology  Based on WiFi technology (802.11g)  The 802.11g specification is a standard for wireless local area networks that offers transmission over relatively short distances at up to 54 megabits per second  802.11g operate at radio frequencies between 2.400 Ghz and 2.4835 GHz  In DCN Wireless there are 3 non overlapping carriers available. GHz 2.412 - 2.417 - 2.422 - 2.427 - 2.432 - 2.437 - 2.442 - 2.447 - 2.452 - 2.457 - 2.462 - 2.467 - 2.472 - 2.400 -2.484 - GHz 012

Security Systems DCN Wireless Demonstration Guidelines 23.Jan.07 Carriers & Channels GHz 2.400 -2.484 - GHz 012 Ch 1 2.412 - Ch 22.417 - Ch 32.422 - Ch 42.427 - Ch 52.432 - Ch 62.437 - Ch 72.442 - Ch 82.447 - Ch 92.452 - Ch 102.457 - Ch 112.462 - Ch 122.467 - Ch 132.472 - WLAN  In this example there is a Wireless Lan network which is using channel 3. Carriers 0 and 1 have an overlap with this channel. Therefore Carrier 2 must be used for DCN Wireless.
