look what i found at clear's website: Your Clearwire connection is very secure. That’s because Clearwire wireless technology uses OFDM transmission protocol, featuring a design standard that includes secure wireless data transmission. Wi-Fi operates on unlicensed 2.4GHz frequencies, making it vulnerable to scanning and packet interception. Clearwire operates at licensed 2.5GHz frequencies. Licensed frequencies and OFDM make for a very secure connection. Any ideas why i can't get wimax detected with my NIT?
