I don’t know about you, but I don’t always get great WiFi speed when spending time in my garden. Your tablet or laptop could easily tell you WiFi signal strength. Why use those when you can rely on the Wi-Fi Detector Shirt to get the job done? It is an interactive shirt that shows signal strength for 802.11b or 802.11g networks. The decal is removable, so you can watch your shirt with no issues. You will need AAA batteries for this shirt, but the battery pack is in a small pocket sewn inside the shirt.
