i believe their are several
i think 'cradle point' and asus have some models that do this
cradle point used to be mentioned on here quite a bit
how ever if you have a poor cellular signal for the phone or hot spot
you need either an eternal antenna or a cell phone booster aka "amplifier'
some of us use the wilson/WeBoost 'sleek' model
its an amplifying cradle with external antenna, place phone or hotspot in the cradle to increase cellular signal strength
I can explain it to you.
But I Can Not understand it for you !
