DICENTIS Wireless Conference System system with redundant WAP
The system can be configured with a redundant DCNM‑WAP provided the following conditions are met. The procedure for subscribing a redundant DCNM‑WAP is described in the Configuration manual.

• Preferably both WAPs are connected to an Ethernet network switch with a DCN multimedia System Network Cable or a standard network cable, and the Ethernet network switch is connected to a laptop or PC.

Note: The use of an Ethernet network switch and cabling are preferred during the subscription process, because this makes it easier to access and subscribe the WAPs. When subscription of the secondary WAP is complete, the Ethernet network switch and cabling can be removed if it is no longer required.

• The WAPs are correctly positioned (there should be a minimum distance of one meter and a maximum distance of three meters between the two WAPs).
• The WAPs are powered up and the Wireless Conference System is operational.
• Both WAPs have been correctly configured in the Installation Wizard and have unique names for:
• Network name (SSID)
• WPA2 key
• Hostname
• Both WAPs are set to the Standalone (factory default).
• The applicable licenses are available for the primary WAP and the secondary WAP (the redundant WAP requires its own set of licenses for features such as voting and dual-use at seat to continue working if the primary WAP fails).
• If recording/playback and PA are required, make sure audio connectors are connected to the balanced In/Out connectors of both the primary and secondary WAP.
• If access to the API (for showing voting results) and web browser settings is required, make sure Ethernet cables are connected to both the primary and secondary WAP.

Extended system requirements

The following requirements are valid if you want to extend your system with a network switch or cameras:

• Network switch and camera installation instructions are not part of this installation manual; please consult the product related documentation of the supplier.
• A video switch is required, when more than one camera is required. The following switches are supported:
• tvONE CORIOmaster mini C3-510
• Kramer MV-6 3G HD-SDI Multiviewer
• A DHCP server is needed for both the Wireless Access Point and the cameras.

Cameras
Typical, the Bosch HD Conference Dome is used. Refer to product related information on: www.boschsecurity.com > Country of your choice > Conference Systems > DICENTIS Wireless Conference System > HD cameras and accessories.

Planning

Use the guidelines in this section to plan the design and installation of your DICENTIS Wireless Conference System.

Unpacking

This equipment should be unpacked and handled with care. If an item appears to be damaged, notify the shipper immediately. If any items are missing, notify your Bosch representative. The original packaging is the safest container in which to transport products and can be used to return products for service if necessary.

System design planning

• If the DICENTIS Wireless Conference System is used in an area where there are other WiFi access points within (30 m) range of the DCNM‑WAP, you should apply frequency planning. Put the other access points on manual frequency selection to prevent the WiFi networks from trying to use the same frequency.
• Probing of other WiFi devices (such as smart phones or tablets) to the DICENTIS Wireless Conference System can cause unstable functionality. Therefore it is strongly recommended that these WiFi devices are connected to dedicated WiFi access points. These WiFi access points must have sufficient capacity for WiFi connection of all nearby WiFi devices.
• The maximum distance between the DCNM‑WAP and the Wireless Devices can be reduced by RF absorbance of signal radiation of certain building materials e.g. concrete, and or metal.
• When using a smart device with a wireless connection to the system, the maximum number of connected Wireless Devices must be reduced. With 1 smart device, 119 Wireless Devices can be controlled, and up to 3 smart devices can be used to control 117 Wireless Devices. Otherwise use a wired connection to the DCNM‑WAP to maintain the maximum number of 120 Wireless Devices.

Installation planning

1. Make sure you have all components for installing and connecting the DICENTIS Wireless Conference System (see System overview).

• Familiarize yourself with the products capabilities of the DICENTIS Wireless Conference System (see System overview, and the paragraphs Control capacity and Coverage area in this section).
• Use only Bosch specified installation materials and tools (see Additional components).

2. Determine the end‑user requirements, typical questions are:

• The number of seats?
• How many chairpersons are required?
• Should the Wireless Devices be in dual‑use mode?
• Is voting required?
• Is identification required?
• Is camera control required?

3. Calculate the number of seat positions. This depends on, the number of participants, the number of chairpersons and whether the Wireless Devices will be in single‑use or dual‑use.

• Example: The system requires 25 participants and one chairperson. Two participants will use one Wireless Devices. Use the following formula to calculate how many devices are required: Round up (participants/2) + chairperson.
  In this example 25/2 = 12.5 > Round up (12.5) = 13 + 1 = 14 Wireless Devices.

4. If camera control is a required, the license DCNM-LCC must be added to the system. Do not forget to add the cameras to the system. The Bosch HD Conference Dome is supported.
5. Decide if, and which type of, cabling is required. See System overview.
6. Decide on how to power the Wireless Access Point (DCNM‑WAP). See System overview:

• Via the AC/DC power supply adapter (supplied with the DCNM‑WAP). Or:
• Via Power over Ethernet (PoE). Or:
• Via Ethernet switch. Or:
• DICENTIS (Audio) Powering Switch.

7. Provide a mains power supply connections nearby the equipment which requires mains power supply.
8. Decide on how to power the other devices used in the system (i.e. Ethernet switch, cameras etc.). See System overview,:

• Via their own (mains) power supply provision. Or:
• Via Power over Ethernet (PoE), if possible.

9. Decide on how, and where, to install the Wireless Access Point (DCNM‑WAP). See Installation Wireless Access Point:

• Wall, ceiling. Or:
• Tripod floor stand.

10. Decide where, and how to place, the Wireless Devices (DCNM‑WD and/or DCNM‑WDE). See Installation Wireless Devices and Accessories.
11. Decide on how, and where to attach the Charger to a wall. See Charger.

Control capacity
