Power verification.

Butterfly is a low-cost, hand-held power meter designed specifically for 802.11b, a and b/g WLANs. The receiver attaches directly to any access point or network interface card with an SMA external antenna connection and measures both 2.4 GHz and 5.1-5.9 GHz UNI bands (I,II and III) standards for verification of power levels (0 to 30 dBm). Other features include a built-in backlit display, simple keypad menu navigation and removable, rechargeable Ni-MH batteries for portability.--Berkeley Varitronics Systems
