The GPRS/EDGE data speeds on the iPhone are known to be slow. For serious web activity, it’s best to use the Wi-Fi connection. But what if you’re too far from your closest hotspot? Seth Fogie considered this and decided to upgrade the wireless antenna in the iPhone.

The iPhone has two main methods by which it can communicate with the Internet. The first is over the infamously slow GPRS/EDGE network, and the other is via a 802.11 wireless network. Due to the simple fact that a Wi-Fi connection is much, much faster than GPRS/EDGE, it is extremely advantageous to use Wi-Fi whenever a wireless network is nearby. Unfortunately, the antenna for the wireless network is embedded in the iPhone device and is only about an inch long (Figure 1). So, in our typical fashion (see our previous articles on adding antennas to a PSP and a Wii), we decided to experiment. We wanted to see if we could upgrade the wireless signal strength by replacing the phone's existing antenna with an upgraded version.
