What Are DECT Cordless Phones?

DECT stands for Digital Enhanced Cordless Technologyand refers to the European standard of cordless phone technology which results in improved sound quality and performance over longer ranges compared with older cordless or Wifi cordless models.

DECT phones have a base station that can typically support up to 6 cordless handsets. The base station connects to the network by either an analogue or digital phone line, and handles the radio part of the connection to and from the handsets.

The range of a DECT cordless phone varies depending on the model but will typically be around 50 metres indoors and up to 300 metres in an open space, giving users the flexibility to move away from their desk and to other areas of the office or building without missing vital calls. Booster units can also be installed to increase the useful range as far as is needed.

As well as being used for making and receiving external calls, DECT phones can be used to call other people on the business internally.

DECT phones usually have a battery life of around 12 hours when in use and up to two hundred hours when in standby. The handset will automatically recharge each time it's replaced onto its base unit cradle.

When integrated with a modern VoIP PBX phone system, some models will allow users to send SMS text messages and even access their emails as part of a broader Unified Communications framework.


In order to reduce so-called electric smog (the invisible electromagnetic radiation resulting from using both wireless tech nad mains electricity) DECT system employ various to minimise the transmitting power of both the base station and the handset while in idle mode. These methods are often called ECO DECT.

Cordless Phone Costs

The cost of a system will consist of the handsets, the base station, installation of a phone line if required, and if you require a larger range of movement repeaters to boost the wireless signal. The handsets themselves can start from as little as £12.00 plus VAT and can be over £100 for the most advanced models.

The more expensive handsets will generally offer more features, longer battery life, increased range and better quality calls. The overall cost will very much depend on the number of people using the system and how many handsets they need, with overall costs ranging from a few hundred pounds to over a thousand pounds for larger systems.

If you want to expand your system as the business grows, DECT cordless phone systems are easy to add to by simply purchasing additional base stations and handsets as required.

Installing a DECT cordless system should also go some way to saving your company money as there should be reduced reliance on more expensive, extended mobile or smartphone use.
