Standard casing
The Wirnet iBTS station is built on a robust IP66 aluminum enclosure of 280 x 250 x 120 mm.
It is composed of two separated parts: the frame and a lid. The lid tightens to the frame
trough M5 screws, hidden by two plastic clip-on design covers.
A mounting kit is screwed on the back of the enclosure, allowing several mounting
configurations: wall mount, pole mount and metallic strapping.
The left and right sides of the enclosure integrate two waterproof screw-in vents to equalize
the pressure inside and outside. This reduces condensation by allowing air to flow freely into
and out of the sealed enclosure. At the same time, they provide a durable barrier to protect
the internal modules from contaminants like dust, sand, water, etc … improving reliability,
safety and longer product life.
The bottom side of the enclosure is dedicated for the connectors:
1 x M25 cable gland used to introduce the Ethernet cable (PoE) inside the enclosure
3 x N-SMB adapters used as RF interfaces for the antennas:
o
1 for GNSS antenna (GPS)
o
1 for WAN antenna (GSM/HSDPA/LTE)
o
1 for LoRa antenna. The number of LoRa antenna interfaces can be extended
to 6.
8 x M16 blind stops. They are considered as provisions for N-SMB connectors to be
used for additional antennas (LoRa or WAN) or external power supply cable gland.
Blind threaded standoffs are inserted in the rear side the enclosure. They are used to screw
and maintain the modules inside the enclosure. The modules can be easily inserted and
extracted for maintenance and upgradability purposes.
The Figure 5 below shows the different components inside the enclosure.
