Wireless network design

1. 1

Introduction

The DCN Wireless has three parts: the wireless
network, the DCN and the optical network. This
chapter tells how to design the wireless network.
1.2

Limits

Limit 1: Control capacity
The maximum number of devices in the wireless
network that the central control unit can control is 150.
Limit 2: Coverage area
For a good operation of the wireless part, all wireless
discussion units need to be in range of the wireless
access point. The wireless access point has a typical
maximum coverage area of 30 m by 30 m. To
determine the exact coverage area the coverage test kit
can be used.
Note
You can change the power value of the wireless
access point (refer to section 11.6.4).
Limit 3: Frequency
The wireless network must operate in a different
frequency band than adjacent wireless (computer)
networks (refer to section 1.3).
Limit 4: Language Distribution enabled or
disabled
If all wireless discussion units have software version 2.35
or higher, language distribution in the wireless network
can either be enabled or disabled. This system setting
will affect all units.
Note
Wireless discussion units that have a software
version lower than 2.35 will only work when
language distribution is disabled.
For information on how to enable or disable language
distribution in the wireless network, refer to section
10.6.11.

Wireless discussion units that have software version 2.35
or higher have improved signaling and behavior with
respect to subscription and connection, which is more in
line with the wired DCN units (refer to section 14.6).
The difference in signaling can be used to detect the
software version of the unit. This can be 2.35, or a
higher or lower version.
If the wireless discussion unit has an integrated channel
selector, the software version is shown on the channel
selector display when:
• the unit is switched on but is not subscribed to a
wireless network (refer to section 14.6 for
information on subscription).
• the unit is in programming mode (refer to section
14.3.1).
For information on how to enable or disable language
distribution in the wireless network, refer to section
10.6. 1 1.
Limit 5: Number of Language Distribution
Channels
The wireless network has a maximum of 10 language
distribution channels, excluding the channel for the
floor. The total number of language distribution
channels in the system, is set via the interpreter desk
(refer to section 33.6.6.4 in the DCN Next Generation
Installation & User Instructions).
If there are more than 10 Language Distribution
Channels, only the first 10 channels will be available for
the wireless network. All higher channels will only be
available for the (wired) DCN network and/or the
infrared Integrus network.
