The Instituto Costarricense de Electricidad says it has enlarged coverage of its 4G cell telephone network.
The company said it invested $19.9 million to do so and installed 80 new sites this year. The total is expected to reach 195 next year, the state firm said.
The firm said it also was installing devices inside large buildings to better handle communications there.
The 4G system, the fourth generation, is based on the long term evolution technology. The firm said that its mobil Internet network is 10 times faster than competitors.
