My neighbour bought a 10 meter long USB extension with booster from CDR King last year.. He plugged in the Dongle and attached it to a type of flag pole with a plastic cup over it to protect from weather.. He winched it up high and it improved his signal a lot.. You need to find out which gives better signal in your area.. Globe Tatoo or Smart "broadband" dongle.
I suggest you go to your local globe office and ask if Wimax wifi works in your location.That is a 1MB connection..(Supposedly)
Also check out if other Smart or PLDT services can be utilised there.
Good luck with that!
