solutions to cellular bandwidth issues

It sounds like you're speaking it about a cellular booster which should not have enough juice to affect local towers.  But it sounds like it is properly registered with the FCC, and someone has complained.  

Cellular booster only requires electricity, and an indoor and outdoor antenna/s  in order to amplify an existing signal and bring it indoors.  

Cell boosters usually can only amplify an outside signal indoors with a gain of about 20 - 50 DBM.  

AT&T markets something it refers to as a "cell booster pro", it is not in fact a cell booster It is an LTE microcell for large deployments. It requires set up with an internet connection, and an AT&T postpaid account.  

If the business already has internet and Wi-Fi setup, it would likely be redundant because everyone can just use Wi-Fi to connect for talk text and data.  

Thanks for the information i will look into the Cell Booster Pro. As it is described it will not work for our facility due to the limitations on active connections and area coverage, but perhaps if we can implement multiple systems it could work.

Hi there,
We want to help. Let’s meet in a Direct Message on this. Please check your Direct Message Inbox (it’s the chat icon next to the bell icon in the upper right corner of the forums).

As stated in the info ...

A single device will cover 64 devices and up to 15,000 ft²

Multiple units (3) Will connect a 45,000 ft² area and up to 192 devices simultaneously.

That system will not work for my application (500+ devices over 272000 square feet) but thanks for the information. I will have to look into a new over the air repeater system.

The term "cellular repeater"  = "signal booster/cell booster".

And apparently you've already been told you can't use one by the FCC because it's interfering with local signal for the neighborhood.  Why would you think a different booster is going to solve that problem?  

Boosters/repeaters are not carrier specific. Most towers are also not carrier-specific. Towers will carry more than one service provider and a booster or a repeater amplifies cellular frequencies common to all US carriers.   

It's nice you're trying to do this for your workers but if you're going to be told you have to shut it off because of the interference it *does not make sense* to invest in another device that the FCC won't let you use.  Especially when you already have a device that does work, you're just not allowed to use it.

Hi Michael, if you have any further questions, please feel free to reach out to us. We'll be standing by.
