RADWIN 5000 HPMP User Manual Release 3.1.00 2-4Additional Indoor Site Requirements Chapter 2Additional Indoor Site RequirementsThe ambient operating temperature should be 0 to 50°C (32 to 122 °F) at a humidity of up to90%, non condensingStage 3: RF SurveyThe RF survey examines the wireless environment of the installation site, to determinewhether there are available channels within the radio operating frequency band. An RF surveyis performed using a spectrum analyzer.It is advisable to familiarize yourself with the spectrum analyzer before going out on site, spe-cifically the Max Hold and Marker functions.You should perform the RF survey at each of the proposed sector sites.The survey should be carried out during a busy time of day, to best judge the worst-caseradio interference. Allow 2-4 hours duration for a good RF survey.RF Planning for Dense Installations and Collocated SitesInterference may arise from• Self interference from collocated RADWIN radios• Other collocated radio devices installed on the same site.To avoid or minimize interference, follow these recommendations:• For collocated RADWIN units, use an HSS unit to synchronize between them. Select adifferent operating channels for each collocated RADWIN unit.• If one or more collocated units are not RADWIN units, ensure that there is a physicalseparation of at least three meters between a RADWIN unit and any other collocatedradio on the site.• Use the largest possible frequency gap between these units• Choose the best frequency channel (as clear as possible form interference). You maybe able to change the band used for the sector - depending on HBS model and regu-lations.• Decreasing the Tx Power of a sector will reduce collocation interferenceNoteUse the Link Budget Calculator to determine the minimum Tx Powerrequired to maintain sector stability.
