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.

Carriers & Channels

In the 2.4 GHz frequency range there are up to 13 channels available for
wireless communication.

In DCN Wireless the following is applicable :

Carrier 1 = Channel 6

Carrier 2 = Channel 11

Demonstration 1 – Using a WiFi Seeker


You must make sure that adjacent wireless computer networks do not
use the same frequency range as the wireless network of the DCN.
A WiFi Seeker can be used to find out which Wireless LAN channels
are active

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.

Demonstration 4 – Battery Management

Seperate Battery Packs
 Easy to replace during a meeting (or during a coffee break)
 If you need to recharge the batteries at the end of the day, you can
leave the units on table, recharge the batteries separately and
easily place the batteries back into the units. This also saves a lot of
time because you don’t need to change the synoptic view on your
control PC
