english 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 4m2 - 16m2 per headset (2m - 4m base-to-base separation). # For 82 - 169 Bluetooth® wireless technology headsets in one area, ensure on average 16m2 - 25m2 per headset (4m - 5m base-to-base separation). # Above 169 Bluetooth® wireless technology headsets in one area, ensure minimum 25m2 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: 2m2 - 8m2 area, 1.4m - 2.8m separation # 82 or more headsets: 12m2 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 (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 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 Section 7.4: 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.
