The Comision Federal de Competencia (CFC), Mexico’s antitrust watchdog, has published its ruling on the terms for the country’s upcoming auction of frequencies in the 1700MHz and 1900MHz bands, BNamericas reports. The commission has set a 90MHz cap on the amount of spectrum any single wireless operator will be allowed to obtain, despite having initially favoured an 80MHz limit. The restriction will apply not only to the 1700MHz and 1900MHz bands, but also 800MHz frequencies. The CFC claims that its proposals will encourage the entry of new operators to the Mexican wireless sector without impacting the growth of existing players. The spectrum auctions are expected to take place before the end of the year.
