2 INSTALLATION SITE RECOMMENDATIONS
SMK Access Station mini has been developed for indoor and outdoor operation. It
is certified including a 2dBi hinged half wave antenna that can be set straight or
swivelled at right angle
Note: For outdoor operation, the adjunction of sealing cover is mandatory.
Recommendations within this chapter are available for all the SMK operating bands.
2.1 Antenna placement and near field clearance
Whatever the type of installation, SMK antenna shall be clear of massive
obstacles or metallic surface within 1m, since possibly altering operation.
When site placement constraints do not allow to respect antenna clearance,
nominal service may not be achieved.
•
For wall mounting inside a building, the antenna can be swivelled at a 90°
angle, to mitigate shadowing.
•
For indoor installation, the SMK shall not be used within a metallic closet or
within technical room with metallic door.
•
For outdoor installation, SMK antenna shall be placed vertically.
2.2 Coexistence with other RF equipment
As any radio equipment, SMK access station mini must be installed with proper
decoupling precaution versus other radio transmitters. Should the quantified
decoupling recommendation listed below be infringed, SMK access station mini
would enter degraded operation, including and coverage reduction.
Decoupling protection is naturally expressed in dB, however for practical reasons,
this guide presents decoupling recommendation in terms of antenna alignment
and physical separation.
Systems co-location
In case of third party equipment co-location, SMK antenna shall be installed
vertically collinear to the existing antennas, with a clearance of 2m.
For indoor installation, the base station shall be installed at a minimum clearance
of 2 meters from any fixed radio device (e.g. DAS, or Wi-Fi access points).
Co-location of SMK access station mini on Telco site
or
with third party
SRD/ISM systems operating on the same band is forbidden.
