4.5 Mounting of the enclosure
The Wirnet iBTS enclosure must be mounted on any concrete pedestal, concrete wall or any
non-flammable surface (UL94-V0).
It must not be mounted on a flammable surface.
The mounting kits delivered with the Wirnet iBTS stations allow fixing the product in
different ways:
-
Wall mount
-
Pole mount by U-bolt
-
Pole mount by metallic strapping
Two different mounting kits are available depending on the casing:
-
One for the Standard casing
-
One for the Compact casing
Universal antenna brackets or specific antenna brackets are provided with the LoRa
antennas. Universal antenna brackets can be directly mounted on the Compact casing
mounting kit.
Dome antenna brackets are provided with the LTE antennas and GNSS antennas.
All these several kits are detailed in the following paragraphs.
4.5.2.1 GPS, LTE and LoRa antenna considerations
The Wirnet iBTS integrates GPS, LTE and LoRa antennas. GPS and LTE antennas can be
integrated inside the enclosure (compact casing) or are external to the enclosure (standard
casing). The LoRa antennas are always external to the enclosure.
The position of these antennas, in an open environment, is important and could determine
the overall performance of the Wirnet iBTS.
The GPS antenna requires an open sky view to be able to receive a maximum number of
satellites. This determines the PPS clock accuracy and finally the TDOA / geolocalization
accuracy.
The antenna is provided with a 5m coaxial cable. Extension coaxial cables could be used to
reach the optimum sky view but are not provided by KERLINK.
The LTE antenna requires an open environment to optimize the link with the BTS in the area.
The benefits are less multipath fading and better data throughput.
The antenna is provided with a 5m coaxial cable. Extension coaxial cables of could be used to
reach a better position but are not provided by KERLINK. However, beware of the insertion
losses!
