   DECT uses the upper portion of the 1.8GHz band in Europe, Asia, Australia, and South America while US cordless phones are based on DECT 6.0 which uses the 1.9GHz band, none of which should interfere with any of the 802.11 wifi frequencies. I think the answer should be B and C.

   wimax operates at 2.3 GHz, 2.5 GHz, and 3.5 GHz frequency bands, with additional spectrum bands to come.

   zigbee at 2.4 ghz

   GSM In Africa, Europe, Middle East and Asia, most of the providers use 900 MHz and 1800 MHz bands

   not sure why the answers are A and B ?? Any guess ?
