Synchronization and Deployment Guide
—
Are there more sites (sub-sites)?
» If there are several sites - the remote site(s) (i.e. those where it will not be
possible to establish synchronization) must be DECT/IP DECT system(s)
Study blueprints of building
—
Consider the building materials
More dense materials means less radio propagation and therefore more base stations
Environment
Moving interior (warehouse, production facility). Much equipment moving around will
influence the propagation
Metal can cause reflections which will influence propagation (i.e. metal blinds, metal
beams, metal shelves, rebars, shielding foils)
Where are fire doors/walls placed? These will influence propagation
System usage
—
Where are people placed? (those that will use the DECT/IP-DECT system)?
—
Are there areas with (extra) high voice-traffic load like:
Canteen
Nurse office
Etc.
Rough estimation of equipment (if possible)
A rough/budgetary estimate of equipment/base stations can be calculated according to below:
Open area (indoor)
Office area
DECT systems: [Size of area to cover in m2]/800 = number of digital base stations
Necessity: approximately 25 m between the base stations and 15 m overlap to
enable handover.
IP-DECT systems (Synchronization Over The Air): [Size of area to cover in m2]/600 =
number of LAN base stations Necessity: approximately 22 m between the base
stations and overlap from base station to base station.
IP-DECT system (LAN synchronization): [Size of area to cover in m2]/800 = number of
LAN base stations Necessity: approximately 25 m between the base stations and 15
m overlap to enable handover.
