1.1. INTRODUCTION:
Telecommunications is now an integral part of the social, economic and political issue of the world. Networks
of the future will be digital and intelligent and will offer high transmission capacity and bandwidth
in addition, they will be easily accessed and connected while its services will be personal and tailored to
individual needs. They will allow us to interact in ways previously not possible - available at any time and
any place. In addition to providing entertainment and business services, networks of the future will provide
education, health and other public services.
Major advances in communications technology have substantially widened the range of services carried
by the network. Satellites, microwave radio, optical cable links, digital switching and transmission, offer a
potential for the improvement of quality and for the extension of access to the most remote areas. The pace
of technological change is increasing while the magnitude of demands the future will make on our creativity
and capacity to adapt is great. Customers will demand more than just state-of-the-art technology; they will
want convenience and increased control over their lives that easy and affordable information access can
provide while businesses will look for total telecommunications solutions that will not only enable them to
remain productive and compete globally but will also give them a competitive edge.
Ubiquitous Telecommunication Technology (UTT) can be well-placed to meet these challenges ahead and
meet the varied needs of our local and international customers and pave the way for the region's new
dynamism in the telecommunications industry well into the 21st Century.
As the technology and mode of transport are changing fast, a broad approach to suit all future type of
services will have to be born in mind, while designing the infrastructures for the buildings. A properly
designed building with clear Access path supports the triple play services (viz) telephony, data and Video
services. Also, supports future advanced services, warranting higher speeds and higher bandwidth, planned
to be available in near future, for faster provision of services.
The present booklet is to provide guidelines for consultants, contractors the details on the in-building
facilities required to be considered at the design stage.
The details provided are a general insight and the minimum requirements of UTT for the new buildings,
primarily to develop and deploy FTTH (Fiber to Home).
