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).
• If you install fewer than 25 Jabra Bluetooth® wireless technology headsets in one area, you are advised to
separate headset bases so that they are at least 1 – 2m apart.
• If you install more than 25 Jabra GO headsets in one area, then you should observe the following conservative
planning assumptions (valid for Bluetooth® wireless technology class 1 operation):
# for 26 – 81 Bluetooth® wireless technology headsets in one area, ensure on average 4m 2 – 16m 2 per
headset (2m – 4m base-to-base separation).
# for 82 – 169 Bluetooth® wireless technology headsets in one area, ensure on average 16m 2 – 25m 2 per
headset (4m – 5m base-to-base separation).
# above 169 Bluetooth® wireless technology headsets in one area, ensure minimum 25m 2 per headset
(minimum 5m base-to-base separation).
• The planning assumptions are conservative in the sense that they assume users are on call 100% of the
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 2 – 8m 2 area, 1.4m – 2.8m separation
# 82 or more headsets: 12m 2 area, 3.5m separation
• Use of the headset’s power save mode is recommended for a high capacity installation.
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 Bluetooth® connectionS and the PaiRing taBle
Once you have paired it with your mobile phone and Jabra GO base or Jabra lInK 350 UsB Bluetooth® adapter,
the headset manages its Bluetooth® connections automatically. however, you might sometimes need to manage
your Bluetooth® connections and pairing table more carefully.
Making and changing Connections
the headset is able to maintain up to two connections (typically the Jabra GO Base and a mobile phone). If your
headset already has two connections and you would like to remove one, use the touchscreen menus (see the
sections “Settings menu” and “Forcing Disconnection/Reconnection via the touchscreen”) and/or turn off the device
you wish to disconnect from the headset.
If two paired devices are turned on and in range but fail to connect automatically, you can connect manually by
doing one of the following:
- to connect to the Jabra GO Base, select Reconnect from the base touchscreen.
- 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 “Pairing 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 the section “Pairing with
other Bluetooth® wireless technology Devices” for details.
