Caught a decent shot of a 2.5 RRH just before the tower crew flew it. I got pulled into a ticket for an outage at the site and noticed the door was open, so I went for a ride to see who was there. I added another photo of the entire assembly as well.

 

Because of the way they had to mount the pole to the t-frame, they couldn't connect the jumpers until it was secured.

Now that's a beautiful thing.

 

We really are seeing the future of wireless here.

Can the RRH be mounted remotely if needed?

When you say remotely you mean "nobody had to be there to physically mount it but somehow it gets mounted anyway"? 😁

Well, some towers have the RRU mounted at the base station... Can it be mounted remotely for the B41 equipment?

Certainly is not an ideal condition, but yes they can be put into what some call a ground mount radio unit type setup. Essentially the way most setups were done before network vision decided to pop em up top and get all that distance out of the way.

I'm pretty certain GMOs do not get LTE. The determining factor is does the antenna at the top support the bandwidth needed and the frequencies? If they do then the RRHs wouldn't be ground mounted. So no.

Not to mention 8T8R requires specific antennas.

If a site is specifically a GMO, it has legacy antennas, so it can't support any 800 MHz services. But that doesn't mean sites can't have RRUs mounted at the BBU cabinets and NV capable antennas (in which case they wouldn't be a GMO). At those sites, all bands should be possible.

 

As far as I know, you usually only see something like that in places like rooftops or small/stealth sites (like "flagpole" sites) like this one from the in-progress thread:

The radios can be mounted anywhere. You just get a severe signal loss from the coax cables the farther the radio is from the antenna. They'll be mounted as close as possible but if it needs to be ground mounted then so be it.

Almost all of the sites in the city of Fresno are GMRs, like this:

The legacy gear is kept up in the air only long enough to get the new NV hardware plugged in. All 6 RRUs are on the ground, like so:

The county of Fresno (and Clovis, and everywhere else on planet earth) has different standards, apparently, so their sites look like more like this:

Will 8T8R require new phone? or can currently released phone take advantage of 8T8R? this giga ohm article say this is being tested in chicago?

 

Do we have a list of 8T8R location? I'm based in the metro chicago area

Does anyone happen to have mounting / bracket details for the Samsung 2.5 RRH's? Need this info to get one of my projects out of PC in Sacramento. Cant find anything online and Samsung will not return my email/call.

Yep.

 

Here's the installation manual with the mounting / bracket / installation details.
