In-train repeaters

Business travelers expect good coverage, including no dropped calls, and data connections wherever they are, for constant
access to the Internet, e-mail, and various mobile device applications.

High-speed train applications present extremely challenging RF environments. The complexities of different terrain combined
with rapidly changing outdoor signal levels of the various networks makes it difficult for operators to provide the coverage and service their customers demand while travelling from city to city or to another country. To improve the reliability of wireless signals on trains, distributed antenna systems (DAS) have proven to be a more cost-effective method over installing expensive base stations.
