Increasing wireless range
I can't find a better place to put this, so here goes.
I often go to a cabin where I have cell phone service, but no wifi. The cell phone service is just OK, not a great signal.
I tether my Windows laptop to my cell phone using bluetooth. It works, although a bit slow due to the weak phone signal. Now, I've seen the cute use of an aluminum can formed around a wifi antenna to focus it and increase its directionality and range.
My question is: Would it help to create a similar, but slightly larger, surround for my cell phone to direct and focus the signal in the direction of the cell tower? (I can locate the cell tower on a map)
Thanks for input or ideas!
