In trodu ction
In the 1 980s, structured cabling evolved to provide a solution for the
delivery ‘to the desk’ of a wide variety of different information
technology (IT) ‘applications’ and telephony over a common cabling
infra structure . Fortunately, th is in itia l implementation of integrated
office networks to support IT and telephony services involved
personnel that had some knowledge of each other’s expertise and
were involved at a specific point in the construction or refurbishment
of buildings.
With in commercia l prem ises, be they offices, industria l, reta il, etc. ,
the range of services that can be delivered over structured cabling
ha s grown a s the impact of Internet Protocol (IP) technology ha s
blossomed. The advent of wireless networking ha s not dim in ished
the role of structured cabling, a s the cabled subsystems for the
wireless distribution networks use applications that are specifica lly
designed to be supported over structured cabling.
When matched to the recent standardization of power over Ethernet
(PoE) and PoE-plus, wh ich is capable of providing approximately
25 W to each connected point, th is growth ha s been fed by a
sign ificant uptake in information commun ications technologies
(ICT)-application ba sed solutions for building management and access
control systems.
Th is more recent integration of services over IP networks is genera lly
termed ‘convergence’, and it ha s a great many impacts on the
preparation , design , pre-construction and construction pha ses of
building projects.
‘Convergence’ provides the same econom ic opportun ities en joyed by
the IT commun ity ‘to the desk’ via the use of common applications
ba sed on a common cabling infra structure . However, it presents the
construction industry with some serious cha llenges – and those
cha llenges are presented to personnel who are un likely to be fam iliar
with the ICT world.
