supplement the six base stations already in operation,
thereby expanding service to cover the entire
Olympic area including main roads. The
pagers were used mainly for relaying information
to bus drivers, NOC assistants, and volunteer
supervisors. In addition, 2,120 pagers were
rented out during the Games, with a total of
43,436 messages relayed overall.
Data Transmission Services
A network was constructed specifically for
data transmission, with three main servers
linked in triangle formation by 45 Mb/s circuits.
Data centres were linked with the venues by two
1.5Mb/s circuits. Small-scale Games operations
facilities were set up with an ISDN or a digital
leased circuit with capacity ranging from 64
Kb/s to 512 Kb/s, and ISDN networks were installed
for backup. LAN token rings within the
venues with a capacity of 15Mb/s were installed.
