What it is

RuralConnect is a line of TVWS radios made by the United States company Carlson Wireless Technologies. The line has two types of equipment. The base station (base station) stands at a high, central point. The CPEs (client stations) stand where the connection will be used.

The radios operate on the free TV channels of the UHF band, between 470 and 698 MHz. The manufacturer describes the line as software-defined and with dynamic spectrum management: the equipment chooses free channels so as not to interfere with TV broadcasters. Certification is by the FCC, the telecommunications regulatory agency of the United States.

In TECER

It was the TVWS kit acquired for Phase 1. The purchase took nine months, because of the small number of manufacturers, the lack of equipment certified in Brazil and production delays (see Phase 1 (BOLT): the project and the setting).

During the tests in the UFPA/LASSE laboratory, the technical team opened the BS2 base station and found oxidation on the radio frequency connections, which was compromising the performance of the links. The cables sent by the manufacturer performed better than the cables made in the field.
