You can also display the signalstrength as a percentage value. This represents the signalstrength of the package received as a ratio of the maximumpossible RSSI (100%).r Use the navigation key to select the desired displayof the signal strength.dBm: The signal strength measured is displayed indBm. This is preset and is the recommended mode.%: The signal strength measured is displayed as apercentage of the maximum RSSISEN: Not relevantMetering range (measurement interval)The measurement interval defines the time intervals atwhich measurements are taken.Value range: 06–16 (1.0 s–2.5 s)Recommended value: 16r Use the navigation key to select the required measurementinterval.BackStart§Start§§Back§Press the display key to activate metering mode.Press the display key to exit the service menu again.The handset is deactivated.

DECT installations in special environmentsDECT installations in special environmentsThe Projecting the DECT network and Taking measurements chapters describe all prerequisitesand steps for planning a DECT network. In addition to the examples and applicationsdescribed there, this chapter contains notes for special construction or topographicalrequirements.DECT networks over several floorsIf the DECT network is to cover several floors of a building, you must consider the followingpoints when planning the number and location of base stations:u What material are the suspended ceilings made from?If they are reinforced concrete, only one ceiling can be positioned between the basestation and telephone for a direct wireless path. Furnishings and partitions in roomsetc. can restrict the wireless transmission even further.Use measurements to check where further base stations are required.u To what extent must a handover between the floors be guaranteed?In this case, the base stations must be positioned such that stairwells are also completelycovered. Note also that any fire doors or walls can reduce the wireless transmissionseverely.Add the vertical levels of your planned coverage areas to your measurement plan andrecord the vertical transmission of the DECT network.u No handover between floors requiredIn this case you can work with clusters (more cost-effective). If you set up one clusterfor each floor, the base stations of the cluster are synchronised with one another anda handover is possible. A handover is not possible between the floors, but the IP PABXfunctions (VoIP configuration, directories, etc.) are available in all clusters.Stairwells and liftsStairwells often have particularly absorbent walls (e.g., reinforced concrete); access to thestairwell may be restricted by fire doors. Planning of the DECT network is therefore subjectto special requirements here.If you want calls via the DECT network to be possible in the stairwell, the most cost-effectivevariant is to install one (or even several) base station as a separate cluster.If a handover is required in the stairwell, you should check the position of the stairwell tothe corridors (transitions, doors, fire doors), measure the wireless coverage and, if necessary,provide one or more base stations for wireless coverage of the stairwell.Making calls in lifts is usually not possible due to the highly absorbent and/or reflectivematerials. However, if this is a requirement, you can check whether you can achieve sufficientsignal strength and quality for making calls in a lift by installing a separate base stationin the lift shaft.41VoIPon www.voipon.co.uk sales@voipon.co.uk Tel: +44 (0)1245 808195 Fax: +44 (0)1245 808299
