Hardware and Wiring Installation Guide 3
Shielded Wire – A type of wire wrapped in a braided or foil shield that protects it from electrical
interference. Use of shielded wire may be the only solution in a very high-noise environment (see
Section 4.5.4.1).
STP – Acronym for Shielded Twisted Pair. This is wiring usually used in audio system
installations where electrical interference is a prime concern (see Shielded Wire).
Twisted Pair – The wire used to interconnect sensors, collectors, and interfaces is twisted into
pairs to make the wire characteristics more uniform and to cancel out many types of interference
to which the wires might be subjected (see UTP).
USOC – Acronym for Universal Service Ordering Codes. The connectors and wiring adhere to the
USOC wiring practices standard wherever possible.
UTP – Acronym for Unshielded Twisted Pair. This is the typical solid, paired wire used in phone
system installations. It has no outer shield layer (see Twisted Pair).

1.5 Versus Information Systems Estimated Bandwidth
Requirements
Notes: Estimate based on 100 badges on mobile individuals 24 hours a day, 7 days a week.
Estimate based on averages taken from actual data using EtherPeek.
Estimate based on the following system layout:
2 Ethernet Concentrators (with 4 collectors each) @ 4 kbit/sec each 8 kbits/sec
1 Host/Data Server 4 kbits/sec
6 List View Clients (1 also used for reports) @ 2 kbit/sec each 12 kbits/sec
Total bandwidth required 24 kbits/sec
This estimate shows that the Versus Information System should have very minimal
impact on existing infrastructure. The above estimate is based on personnel tracking
applications; in most equipment tracking applications, the actual bandwidth
requirements should be less.
