China Satcom, one of the leading telecommunication operators in China and partner of IPSTAR, connected a weather station in Xigou to VoIP via IPSTAR. The newly installed satellite-based VoIP enhances the telephony system in the station. Built in 1958, the weather station is situated in the outskirts of Urumqi, the capital city of Xinjiang Uyghur in China.
Before the installation of VoIP, meteorologists in Xigou used terrestrial phone lines to contact other stations to report weather observations. However, the usage of telephone is restrictive or limited due to its expensive service rates, especially for long distance calls. With the introduction of VoIP this year, meteorologists are able to make unlimited free or inexpensive calls in reporting vital weather observations in Urumqi and nearby cities.
Aside from the VoIP service, IPSTAR also provided satellite broadband Internet for the station. With the Internet installed, any vital weather information in China is rapidly available in real-time and on a round-the-clock basis. Recently, IPSTAR was used by the station to release an immediate readout of a rainstorm that hit Urumqi and its neighboring cities.
IPSTAR proved to be reliable in places prone to unpredictable rainstorms, like Urumqi. The IPSTAR Adaptive Coding and Modulation (ACM) technology prevents outages during rain fade; thus, it helps enable a seamless communication link between the meteorologists and their instruments in the field. ACM enables the downstream carrier to dynamically change its modulation and coding in response to changing link conditions. |
