The Communications Regulatory Authority of Iran (CRA) has announced a new tender for fixed wireless broadband spectrum in the 2300MHz, 2600MHz and 3500MHz bands. The watchdog says the frequencies can be used for time division duplexing (TDD) technologies such as TD-LTE. The 2300MHz and 2600MHz auctions are aimed at existing fixed telephony and internet providers, while the 3500MHz band is open to all applicants. Successful bidders must agree to open their new networks to competitors on a wholesale basis.
