Cell phone boosters are nicely priced. I am thinking that you can spend almost a grand on these products....
I personally do not place the merit on cell signal boost....or even the 4G MYFI type systems....unless you are fully dependent on them for your life's business.
In my rig I share the mobile hotspot on my phone with the needs of my family. We use a laptop and the NETFLIX acct to access movies and shows. This is displayed on the TV using HDMI. A wireless keyboard and mouse facilitate using and manipulating the laptop to make our selections. I also use a magic jack phone device in this fashion to make calls out over the data plan on my phone in place of using the phone itself.
So there is some examples of a wireless world at use. All of it is expensive if you ask me.
So people additionally have wireless backup cameras....I do not.
