Reasons for Considering iDEN
Traditional PTT radio communications in corporate and municipal environments was
limited by the number of radios and Federal Communication Commission (FCC)
licensing. These restrictions limited the coverage area, contact outside the assigned,
licensed mobile units, and provided little privacy. The iDEN system:
• Removes end-user FCC licensing requirements
• Opens communication to other subscriber corporations and all telephones
1
• Increases the coverage area
• Allows private and group calling
• Optimizes RF resources
• Improves quality with higher frequencies and digital technology
Because of the finite availability of the Radio Frequency (RF) spectrum and a need to
optimize this resource, iDEN technology increases the efficiency of a single 25 KHz
RF carrier by applying up to six times the traffic of an AMPS Cellular carrier.
In addition to the increased channel efficiency, an iDEN system may be deployed to
support communications outside the provider’s network (roaming). The telephone-
style interconnect capability allows users to roam seamlessly throughout linked
service areas. A user may place and receive calls as if the Mobile Station (MS) is on
its home system. This also allows the service provider to offer an integrated service
that includes:
• Messaging (Short Message Service)
• Private, Two-way & Group Call Cellular Telephony Service
•Voice Mail
• Data Networking (Intranet, Virtual Private Network (VPN), Internet).
Since the iDEN system uses digital technology, it provides clear voice quality,
interference is reduced and voice quality is enhanced.
As the wireless industry grows, subscribers are seeking more services and increased
functionality from a single service provider. With iDEN systems, these services and
system outgrowth can easily and quickly be provisioned and made available to the
end user because the radio link reduces installation time and cost when compared to
land-based approaches.
Organization
To support the growing need for emerging telecommunications services, iDEN
systems are organized into different levels or areas. These areas are based on
geographical areas of decreasing size. The areas are:
•Global
•Region
•Domain
• Service Area
• Location Area
•Cell
