Some of you might know that I'm living in Korea and working as a teacher. I was out in the rural mountains near Taebaek, and was hiking along some poles with interesting equipment. I don't know much about any of it, but I knew that you guys would find it fascinating. The most equipment I saw was in photo #8. Some of the heat sinks on the boxes were huge. I did hear a fan running in one of them - the only active cooling equipment I heard on anything up there.

What it *does* look like is that there was a fiber+power run up the mountain and there were repeaters every ~1000 feet or so. At the top of the peak, there was a signal, so I figure this equipment had something to do with it.

Any difference in the installation from what you'd see in the US? Can you tell us anything more about it?

Cheers!

Interesting that there is so much infrastructure just out in the open like that, cabling and all, and seemingly no protection from the general public?

Vandals paradise.

This is a country where honesty in terms of security of personal property is highly valued. I've almost taken it for granted in the 2 months I've been here, but I feel safer here than in most places at home (SF area).

Heh you never see stuff around here that's labled like that. Most everyone thinks that if you don't label it then no one will mess with it.

Some of those pictures make be wonder: Is there not some limit to the amount of "stuff" companies can hang off of one telephone pole without compromising the vertical-ness of the pole?

Looks like those poles are concrete? I assume that is the norm there?

Actually, I think most of the poles I see in the city are wood. However, it seems much of the newest stuff built in Korea is really built to last.

If you look in the last picture, you can see one of those locks in the background, and it appears to not even be locked?!

Christ if that were down here in the US all of that would be wrapped in electrified razor wire for good measure!

Amazing how lax the safety / security measures are on that stuff.

Great pics, good looking installations. Interesting to see it just out there, it reflects the residents respect for the technology that makes their lives better.

Heh...around here that type of installation would last 30 days at most before meth heads stripped it for copper wire. In Wichita I would give it 72 hours.

Looks like the 2nd to last pictures is a pole mounted base station with two different services, probably a 3G and 2G CDMA based system. The other equipment is for RF over fiber, distributed antenna system (DAS). Not sure why they would be using a DAS system in addition to a macrocell unless coverage to this area was very important.

Wow...

Almost a certainty that a similar setup wont last long in the west. (exposed and all...)

The letters CDMA and WCDMA, Optic, tx/rx, LG spell money....

What is this stuff actually worth to some thief? Reverse-engineering? Sale on the black market? I was actually just walking home from work a while ago and noticed some similar exposed boxes, but in the middle of the city.

More likely they would steal the cable than the gear itself.

The cables are full of copper, and copper is worth money.

The gear on its own is pretty useless, and as such would be pretty worthless on the black market. Often there are a myriad of back end systems and software that are required to actually make it useful, not to mention specialised knowledge to operate it which anyone but telco employees isnt going to have.
