DCN Wireless Demonstration Guidelines

DCN Wireless Demonstration Guidelines • This slide show is intended to be a guideline for demonstrating the DCN Wireless system to customers. DCN Wireless Demonstration Guidelines

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. 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 - 0 1 2 2.400 - 2.484 - GHz GHz DCN Wireless Demonstration Guidelines

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 0 = Channel 1 • Carrier 1 = Channel 6 • Carrier 2 = Channel 11 Ch 1 2.412 - Ch 2 2.417 - Ch 3 2.422 - Ch 4 2.427 - Ch 5 2.432 - Ch 6 2.437 - Ch 7 2.442 - Ch 8 2.447 - Ch 9 2.452 - Ch 10 2.457 - Ch 11 2.462 - Ch 12 2.467 - Ch 13 2.472 - 0 1 2 2.400 - 2.484 - GHz GHz DCN Wireless Demonstration Guidelines

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

Carriers & Channels Ch 1 2.412 - Ch 2 2.417 - Ch 3 2.422 - Ch 4 2.427 - Ch 5 2.432 - Ch 6 2.437 - Ch 7 2.442 - Ch 8 2.447 - Ch 9 2.452 - Ch 10 2.457 - Ch 11 2.462 - Ch 12 2.467 - Ch 13 2.472 - WLAN 0 1 2 2.400 - 2.484 - GHz GHz • 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. DCN Wireless Demonstration Guidelines

Carriers & Channels Ch 1 2.412 - Ch 2 2.417 - Ch 3 2.422 - Ch 4 2.427 - Ch 5 2.432 - Ch 6 2.437 - Ch 7 2.442 - Ch 8 2.447 - Ch 9 2.452 - Ch 10 2.457 - Ch 11 2.462 - Ch 12 2.467 - Ch 13 2.472 - 0 1 2 WLAN 2.400 - 2.484 - GHz GHz • In this example there is a Wireless Lan network which is using channel 6. Carriers 1 is using the same channel. Therefore Carriers 0 and 2 can be used for DCN Wireless. DCN Wireless Demonstration Guidelines

Demonstration 2 – Quick Set Up • No need for different types of cables and antennas • The Wireless Access Point is connected to the Central Control Unit by means of our standard optical cable DCN Wireless Demonstration Guidelines

Demonstration 3 – Mounting Brackets • Easy Wall and Ceiling mounting DCN Wireless Demonstration Guidelines

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 DCN Wireless Demonstration Guidelines

Demonstration 5 – Battery Management • Battery Capacity LED’s • To check the battery capacity of the battery pack. DCN Wireless Demonstration Guidelines

Demonstration 6 – Subscription Mode • Subscription mode • Only units which are subscribed to the system in the subscription mode are part of the meeting. • ‘Unwanted’ units cannot participate the meeting from ‘outside’ during a meeting. Subscribed Subscribed Subscribed Not Subscribed DCN Wireless Demonstration Guidelines

Demonstration 7 – Sleep Mode • Sleep Mode • To increase the timebetween charge of the batteries. • To save up to 50% battery time. • To avoid that people play with the units during a break. z z z z z z z z z z z z DCN Wireless Demonstration Guidelines

Demonstration 8 – GSM Immunity • No cell phone disturbances • The wireless units are immune for GSM disturbance DCN Wireless Demonstration Guidelines

Demonstration 9 – Headphone Volume Control • Individual headphone volume control • All Delegates can adjust their headphone volume individually - + - + DCN Wireless Demonstration Guidelines
