Jabra GO 6430 USER MANUAL
7.11 HIGH CAPACITY Jabra GO INSTALLATIONS
Bluetooth® wireless technology uses low-power radio technology for wireless transmission. All radio technologies
are subject to interference from other products using radio technologies commonly used in offices.
Therefore, under certain conditions, you might experience some performance degradation if you install many
Jabra GO headsets in one location or if there is interference from other radio technologies. For Bluetooth®
wireless technology, those performance degradations are typically the result of interference from other
Bluetooth® wireless technology products including Jabra GO products and from WiFi networks. Performance
issues manifest themselves as audible clicks and pops but will very seldom prevent headset operation.
The following rules of thumb will help you plan a high capacity installation to minimize interference and to ensure
an optimal audio performance (a high quality audio based on a signal-to-noise consideration).

• Theplanningassumptionsareconservativeinthesensethattheyassumeusersareoncall100%ofthe
time. In many cases, 50% is a better assumption, even for some contact centers, while typical office planning
assumes 10-15% call time. This reduced on-call time has an impact on the planning assumptions. If the users
are on call less than 50% of time, use the following rules of thumb:
# 26 – 81 headsets: 2m

The area referred to above depends on the building layout. It could be an open space office, or a set of collocated
offices separated by lightweight walls. Offices far apart, say >100m apart, or shielded by heavy concrete walls
should not be considered as one area. The above planning figures are valid if most users are near their bases
(<3m distance). If most users are >5m away from their bases, you should roughly double the recommended area.
In all cases, you should check whether a WiFi network (in particular 802.1 b, g, n type of network) is used. If WiFi
is heavily used, you may need to reduce the number of headsets to ensure satisfactory WiFi performance. Using
more than 20 Bluetooth® wireless technology headsets with 100% call time in an area where WiFi is heavily used
needs a proof-of-concept installation.
Practical customer cases indicate that Bluetooth® wireless technology headsets scale very well in high capacity
deployments.
7.12 MANAGING Blue tooth® CONNECTIONS AND THE PAIRING TABLE
Making and changing Connections
The headset is able to maintain up to two connections (typically to a mobile phone and Jabra LINK 350 USB
Bluetooth® Adapter). If you want to connect to a third device that is already paired with the headset, then turn off
the headset and the unit you wish to disconnect, then turn on the new unit to which you wish to connect and
turn the headset back on again.
Another way to change the connection is to manually pair or re-pair the headset with any device not currently
connected (it does not matter if they are already in one another’s pairing tables). See also the section “Using the
Headset with Other Bluetooth® wireless technology Devices”.
Clearing the Bluetooth® Pairing Table
When you pair two Bluetooth® wireless technology devices, each device adds the other to its own internal
pairing table, thereby enabling the two devices to connect to one another and use encrypted communication.
The Jabra GO headset is able to hold up to 8 devices in its pairing table. If you add a ninth device, the headset
will automatically remove an item from the table to make room for the new one. In this case, an item is selected
for removal based on the time at which it was last used — the item whose last use was the longest time ago is
removed.
You can also clear the entire pairing table manually. To do so, use the Jabra PC Suite. See Chapter 5: Installing and
Running the Jabra PC Suite for more information.
After clearing its pairing table you must re-pair the headset to each relevant device: See Section 7.4: Using the
Headset with Other Bluetooth® wireless technology Devices for details.
