DECT What is it at all?
Digital EnhancedCordless Telecommunications

• Unlicensed use
• Optimised for
• Inhouse communications
• Cellular structures to cover large complexes
• Uncoordinated applications
• Integrated voice-/data-applications
• Current data concepts had been included from the
  very beginning
• Most popular technology for private (as opposed
  to provided) services and applications

Base Station

• IMT-FT (DECT) base stations are connected to
  the UMTS core network via Iu Interface
• USIM-enabled IMT-FT (DECT) terminals offer
  access to the full set of 3G services

25
The Lessons to Learn

• There is a difference between mobile and wireless
  (locally mobile) solutions
• Most solutions require data and voice
• There is a market for privately owned systems
• Service providers need to focus on variety,
  flexibility, quality of service, and support
• There is no technology that makes it all
• Involve all the drivers in the industry
• Dont talk about it, deliver it !!
• Dont advertise the technology limits
