Cordless Phone Deployments
Along with workplaces such as factories, warehouses, schools and hospitals, there are a growing number of traditionally office-based working environments that require flexible, mobile IT and telecommunications networks. It is currently estimated that as many as 80% of workers across all industries are potentially mobile around their workplace and may require access to wireless voice communications.
The standard DECT- (Digital Enhanced Cordless Telecommunications) commonly used for domestic or corporate purposes for digital portable (cordless) phones is an ETSI (European Telecommunications Standards Institute). DECT (like GSM) is a cellular system and the major difference between GSM and DECT systems is that the cell radius on DECT is 25 to 100 meters
The main attraction of a WiFi system is that it offers a single infrastructure for supporting wireless telephony and data, potentially providing a substantial return on investment by reducing hardware costs as well as longer-term operational, maintenance and support costs. But caution should be practiced with deploying Voice on just “any” wireless infrastructure, the WiFi system must be planed out and be of “Voice Grade”. Like DECT deployments WiFi has strict rules to follow.
