We (Vianet Inc) were approached this year by Harte Gold running a remote mine in a small northern Ontario town with a population of about 1000 people. The mine by roads is about another 50km into the bush after leaving the town, but as the bird flies is only about 24km… We worked with the local cell provider to gain access to their tower.
We installed a 3ft slant 45 dish with an AF5X radio on the cell tower. On the other side at Harte Gold we installed a 2ft with ISO beam and AF5X.
We also put a titanium sector up with an AC Prism radio to feed all the trailers.
This was all built on a massive rock formation where we built a concrete pad right on the rock to level it.
On top of this we installed a 96ft Trylon T200 tower. With the level concrete it made very easy to level the tower… The mine then helped us out by drilling holes for the rock bolts for the tower which we then set in with grout. The rock bolts were eventually big pieces of rebar with a special nut that grips them, and were 5 ft long…
Next we needed power for the towers. For the cell tower we installed a telephone pole and ran conduit over to the tower. Here we put a Vertiv (Liebert or Emmerson) cabinet with a NetSure 200 dc power plant. Inside we put a 12 port Netonix dc switch with a -48 to +48v converter to power the site up.
On the Harte Gold site we decided to give a new fuel cell technology a try. We went with an Efoy setup which combines solar panels with a methanol fuel cell. Here we had 24V so we needed to convert it from 24V to 48V for the netonix which, this time an 8 port dc switch.
For the trailers we used nanobeam 5ac gen 2, with a cisco SG300 switch, unifi AC lite, and Cisco SPA514g phones. Most of the trailers have about a 1 year life span so cabling was kept simple…
In their Main office though, it was 7 trailers that were combine into one big office. When they moved the trailer up there all the wiring had been cut, so we needed to re-wire the entire thing. Here we ran everything nicely into the rack, terminated and tested each drop. We also installed a Cisco 891F router and 52 port SG300 switch to power all the phones…
So far feedback has been good because they went from using very spotty cell service to having clear phone calls and internet that is solid now.
