Usually the limitation is to do with the wires. For example, the concept of attenutation is a biggie that network builders must at all times be considerate off. To be brief, a signal can only be sent so far down a line before it "dies".
The problem gets worse if your using wireless. Wireless can only be reliably used over short distances. But unlike wired, there is a lot of variables to consider with wireless. For example, if you sit maybe 15 ft away from your wireless and monitor the signal, then get your dog (hopefully a big dog) to stand in front of the router. You will notice a considerable drop in your signal because the dog is made up of so much fluid.
Wired connections don't have these pitfalls, though from what I can remember from college, I think if someone shines a UV light onto the wire - even though its coated in plastic - the UV will still disrupt the signal. This is something you would have to take into consideration if you were putting a LAN in a niteclub. Obviously wireless is out because off all the people (people are made up from water, the same as the dog) and the wires cant be exposed to any UV lights. That would be a complex LAN to design/construct.

its mainly collusion.
LAN
No, because a repeater does not supply any network isolation - it merely extends the segment distance limitation.
You need at least two devices connected by some type of media to create a LAN. Most LANs would have a distance limitation of not more than 100 meters apart. Other than that, the computer could be placed anywhere within that distance to the other device to create the LAN.
Generally, a LAN's distance includes only several hundred yards
if the LAN is connected to another LAN over a wide distance using point to point links then it becomes part of the WAN (but it doesn't become a WAN by itself).
There is no code limitation for the height distance for recessed lights.
MMF can stand for lots of things. What is MMF?
The distance between two objects may be distorted
The distance between two objects may be distorted.
The distance between two objects may be distorted
Primarily distance, but also the protocols and network medium.
LAN
A LAN has a limited length for distance, and for the number of clients that may be connected to it. If you exceed either, then you may need a longer connection distance, which is afforded by a WAN.
