12 Frequently Asked Questions
Note: The Technical Knowledge Center available on the Business Portal can also be
consulted to find answers to known problems.
MIGRATION from TDM to IP-xBS:
Do I have to register again the already installed handsets on a TDM infrastructure?
No, the already installed handsets will be able to roam to 8378 DECT IP-xBS without
any new registration
Do we need a new handset release to interwork with xBS?
Yes, for the handsets bought before the IP-xBS general availability date.
Can I directly replace an TDM BS with an xBS?
No, xBS and TDM base stations are not supposed to be mixed up everywhere,
because you must respect the minimal distance of 1km between the TDM base
stations and xBS.
Do I need to upgrade my call server for xBS?
Yes, it is mandatory.
“OXO CONNECT” and “OXO CONNECT EVOLUTION” minimal version is R3.0
DEPLOYMENT of 8378 DECT IP-xBS:
When do we need to make a site survey?
It is recommended to first work on a paper plan and do site survey in areas where air
synchronization could be difficult to achieve. Even with only few 8378 DECT IP-xBS it
is recommended to do a site survey.
See the doc[2] for more details.
How to calculate the number of xBS needed in a deployment? Where to put them?
Each base station must see another one with a least a level of -80dBm. It is better to
put the 8378 DECT IP-xBS in line of sight to have a stable radio environment. The
coverage rules are the same as for 8340 IP-DECT DAP.
See the doc[2] for more details
When using external antennas?
When a level of directivity is needed, you can replace internal omnidirectional
antennas with external directive antennas on indoor 8378 DECT IP-xBS (version with
antenna connectors) and on outdoor 8378 DECT IP-xBS. When using antennas with
high gain, the Nominal Transmit Power must be reduced by an amount equal to the
antenna gain minus 3dB in the US only. In most of the directive antenna use cases,
the antenna diversity should be removed via the CS interface (only ANT0 is active,
bottom right one when looking the xBS with its LED at the top).
