Gigaset N720 DECT IP Multicell System / engbt / A31008-M2316-L101-2-7619 / intro.fm / 10.02.2012 Introduction Signal transmission The ideal signal transmission of a base station is shaped like a ring, i.e., so that the registered handsets can be the same distance away from the base station in all directions without the wireless signal being interrupted. However, the transmission is influenced by various environmental conditions.
Gigaset N720 DECT IP Multicell System / engbt / A31008-M2316-L101-2-7619 / intro.fm / 10.02.2012 Introduction Overlapping and synchronising For interference-free cooperation in a multi-cell DECT network, the base stations must synchronise. In order to synchronise the base stations and ensure a smooth handover, the cells must overlap. Synchronisation overlap Handover overlap Version 2, 06.08.2010 A sufficient number of large overlapping zones between neighbouring cells must be ensured.

They affect the subscribers' requirements for the telephone system as well as the technical requirements for the DECT wireless network. These conditions must therefore be recorded and evaluated in a projection phase.

The minimum distance depends on the circumstances. If no obstacles are present, the required distance can be 5 to 10 metres. If there is an absorbent wall or absorbent furniture between the base stations, 1 to 2 metres may be sufficient.

No handover is possible between cells that are not synchronised. They are synchronised via what is known as an air interface, i.e. via the DECT wireless network.
Gigaset N720 DECT IP Multicell System / engbt / A31008-M2316-L101-2-7619 / preparation.fm / 10.02.2012 Projecting the DECT network During the synchronisation planning, make sure that the distance to the base station with sync level 1 is as short as possible from all sides, i.e., that there are as few levels as possible. It makes sense to select the station that is at the centre of your DECT network as the base station with sync level 1.

Traffic volume Version 2, 06.08.2010 The traffic volume is expressed in "erlangs (E)". One erlang corresponds to the continuous full capacity utilisation of one connection channel in a specific period.

For example, coexistence with WLAN is not a problem. Most other asynchronous DECT single base stations do not present a problem either. Problems may occur in special cases, such as an environment where there is a very high level of DECT usage.

The reception power (proportional to the field strength) is displayed on the measuring handset in dBm (£ page 48). A very good reception power is approximately –50 dBm. Systems that are measured at up to –60 dBm generally offer a good quality.

Interference, e.g., through reflection or external systems that influence the voice quality, can also occur with good reception power.
