Microwave Dish / Equipement

Red Squirrel · Post by **Red Squirrel** » Mon May 26, 2003 4:05 pm

I took some pictures for the article I'll be writing and as well as for a school project. So thought I'd share them "pre release".

Enjoy!

First I'll start with inside the building. There's also a radio tower for communication, some radios are for backup while some are for specific purposes. There's a small building beside it (like any other typical tower you would see) and the equipement is inside.

This is the frequency filters for a specific radio. All it is is the waves going in it, and it is set to only let a specific size go through, there's no electronics or anything, it's just a practically empty can! There's one for Transmit and one for receive. They need to filter at different frequencies so they can use the same dish for both TX and RX (much cheaper!).

This is the fibre driver. All the data goes from this place (which is out in the bush) to the main central office where it goes through other equipement like the DEX or whatever else it needs to go through. (pictures of a DEX will be shown tomorow in a seperate thread)

This is the inside of a radio. I forget what it's called, RD something (not RD6, I think it's RD4 or something not sure...)

This is another radio. This one is a RD6 if I belive... (yeah I really need to learn what all the equipement is called, I work too much in the paper work departement

)

This is battery equipement, and in the background it's the actual batteries. I'll get some pictures of bigger batteries tomorow. This, I believe, is what distributes the current to all the equipement.

This is the equipement for the microwave dish that provides long distance service to peawanuk, a place even more north of where I live (yes, north actually gets that far

)

That looks great!

Although, I wouldn't want to get near them....

This is a diagram that shows how the microwave radio works, the waves are actually sent out to a space satelite.

This is a giant generator that can keep the place running for a long time in case of a power failior. Some offices run 24/7 on similar generators, expecially in the north, it's isolated areas in the bush. There's these big tanks that can last a whole year, we have to remotely fill smaller tanks when they empty (an alarm pops up on the SCADA system). Not sure how long this can run for, probably a few days, if you notice the tank in the back.

Hey Tak, just notice you posted there.

This is a pump/compressor that pumps air into the cables, I think it's like 2 psi or something, just enough so that if there's a cut undergroud, it will avoid water and moisture from going in. The pump is specially designed so that when it looses pressure, it kicks in until it's at the right pressure. It's right in the same room as the generator.

This is the actual tower that has the radios, which are basicly dishes that communicate with other similar dishes on other towers quite far away.

This is the microwave dish. It sends waves in space to a satilite which bounces off and goes to another dish up north. That place actually has two dishes, A and B, that way if one fails the other one takes over.

This is a closeup of the dishes on the tower, they are pretty big... and wait till you see what this tower is standing on......

This is the foot of the tower!!!

Incredible huh? The entire tower is sitting on about an inch thick of metal piping (most likely filled and not hallow)

This is the "inside" of the dish. It's the actual microwave driver. Notice the foil, it's to shield the wires since a local radio station was interfeering with it! That's just standard foil, too. High tech stuff or what!

Well this is it for the M/W centre, I'll post another thread tomorow for the actual telecom central office. I'll try to get the telephone switches and everything as well.

I got the pictures for the telecom office, I won't start an other thread but I will write my tour article shortly. I'll make sure to gather as many news@ emails of tech sites to make sure it gets around. I'm sure people will be interested in that.

...and possibly join us afterwards.
