An interesting reverse strategy happening at the moment on my smartphone:
Instead of having Wi-Fi activated on my smartphone by default to benefit from cheap internet access at home and access to local resources I am rather opting now to have it switched-off by default unless I really need it, e.g. to download podcasts, videos etc.
Why? Because my current smartphone's Wi-Fi reception is quite restricted and I've experienced a couple of times that while it could still see the Wi-Fi access point it had difficulties to transfer data due to the reception level. Instead of switching to the cellular network, however, it got stuck. Not good, this is not yet implemented well. Also, I usually don't use any local resources such as a NAS server with my smartphone and I also don't use it as a remote control for any gadgets residing in the home network. I travel too much so my home network is rather basic compared to others.
When comparing the reception quality of smartphone with larger devices such as notebooks it seems that it is in general much weaker. While my notebook sized devices still receive the Wi-Fi network very well in remote corners in my apartment, mobile devices already have difficulties. So unless that changes and I have an all-you-can-eat 3G data package anyway and don't hit the throttling limit, my smartphone Wi-Fi will stay off at home.
What about you, do you use Wi-Fi at home and what are your experiences concerning reception and range?
