CD-R King baru-baru ini memposting di halaman Facebook mereka bahwa mereka menawarkan case peningkatan sinyal 3G+WiFi yang dirancang untuk iPhone 5 dan 5S.

Kasus ini didasarkan pada Linkase Pro yang dibuat oleh perusahaan Taiwan Absolute Technology. Menurut perusahaan, kasus ini menggunakan teknologi EMW (Electro Magnetic Waveguide) yang “mengarahkan energi radiasi yang dipancarkan oleh iPhone menjauh dari kepala dan tubuh serta ke ruang terbuka, meningkatkan sinyal seluler secara signifikan.”

Linkase Pro memiliki harga $39,95, atau sekitar Php1.700, di situs web Absolute Technology. Sementara yang dijual di CD‑R King berharga Php990. Lihat daftar CD‑R King di sini.

im not really sure about boosting the signal reception, since this one doesnt even have a electronics inside, maybe it only helps signal reception when you pickup your phone since your hands block the built-in antenna.
If you were expecting that this thing can fix you low signal issues in your area, wag na umasa, hindi ito high gain antenna, unless they installed a gigantic parabolic antenna right on the case, which is may not happen in real life (because they are heavy and big to be fitted on your phone).
The only real option to fix low signal is add more towers. But stupid community in Metro Manila prevents them installing new signal towers due to their belief that they may get cancer when they have one near on their area which is a world class BS.
