Part 1: Site Survey and Overview of DECT Systems7y Cabling details: a specification of cables already present on the site and a list of newcabling required, including the distance between the Base Station and IWU card for existingand new cabling.y Copies of the maps of the site with the position of Base Stations and cell boundaries clearlymarked.y A list of possible configurations to help the customer decide exactly what is required.y A specification of where Base Stations should be placed. This can be marked on the surveymap, but additional information such as height and fixing instructions should be includedwhere appropriate.y A specification of the areas that will be covered by the Base Stations and areas that maycause problems. This can be useful when testing the system. The theoretical maximumnumber of overlapping cells is 10, if all time slots and frequencies are used. If not all timeslots and frequencies are used, this value is higher, although this is unlikely to be the casein practical situations. For a large site where a thorough survey has been impossible, it maybe prudent to add 10–20% more Base Stations to requirements to allow for unforeseenproblems.
