BRASILIA, Jan 29 (Reuters) - Brazil's federal government is planning to commission a fifth-generation (5G) wireless network exclusively for its own use that will have security requirements for equipment suppliers separate from nationwide networks, according to a document seen by Reuters.

The plan, to be published in the official gazette later on Friday, calls for a 5G network limited to the Federal District, where the capital Brasilia is located. The plan comes as the government prepares a spectrum auction this year for 5G networks, weighing security concerns that have led some countries to excludes China's Huawei Technologies Co as a supplier for those next-generation networks.
