Installation Logistics
- How easy is the cable to work with?
Shielding
- Is the area "noisy"?
- Do you need plenum grade cable => more expensive
Crosstalk
- Where data security is important this is a problem
- Power lines, motors relays and radio transmitters cause crosstalk
Transmission Speed (part of the bandwidth)
- Transmission rates are measured in Mbps
- 10 Mbps is common
- 100 Mbps is becoming common
- Fiber can go well over 100 Mbps but costs and requires experts to install.
Cost
Attenuation
- Different cables can only transmit so far without causing too many errors
