I recently started using wireless broadband for my mobile internet access. While I was able to get around 1mbps at my office location, the coverage doesn't extend well to my housing area. I have to be contented with EDGE. EDGE would still be okay for my occasional internet need at home but the signal strength is so bad that I could barely make any connection.
So, again, I'm off to the internet for a solution. A full parabolic dish would probably be an overkill for my need so I settled with parabolic reflector instead. After about 20 minutes on the PC for the parabolic design and g-code generation; and another 20 minutes on the Sherline CNC, my simple parabolic reflector was born. Made from acrylic (left over from other projects, thus the multiple colors), the reflective portion is covered with the kitchen grade aluminum foil.
As shown above, the reflector can be set vertically on the table or attached to a normal handphone holder bracket for more articulated positioning (below).
How did it perform?
I have no way of measuring true dB improvement but the signal meter on the software provided went up by 2-3 bars when the reflector is used. For now, I could utilise EDGE almost full speed (around 200kbps) without fail. Happy at last... :-)

it seems I'm the only one using it fully. I ha...

salam bro, ada lebih ka, saya dulu cuba gak, tp guna penapis santan, tak power la, dulu hunting wifi, skang nie nak boost up signal guna usb dongle maxis broadband plak,anyway thanks for the idea !!
Ha ha ha... wait in line... :-)
9W2AXN and 9W2ISH have beat you to the request... anyhow, I'll bring it to this friday TT for viewing and testing...
hi bro, thnx for letting me test the device, in an area where i usually get only 1 bar HSDPA unconsistently, i now can get 3 to 4 bar HSDPA consistently. In another area in KL near Maybank tower, where its a known no 3G coverage, only edge, i now get 5 bar on HSDPA consistently. great stuff, but i do get weird looks from my colleagues. cheers.
Waa.. kena cari tudung saji nih...
Do you have details on the critical measurements for making this device? Thanks.
I used this software to calculate...

There are plenty more on the web... just google 'parabolic refelctor calculator'
