NetworkInformation.downlink(en-US) 읽기 전용
Returns the effective bandwidth estimate in megabits per second, rounded to the nearest multiple of 25 kilobits per seconds.
NetworkInformation.downlinkMax(en-US) 읽기 전용
Returns the maximum downlink speed, in megabits per second (Mbps), for the underlying connection technology.
NetworkInformation.effectiveType(en-US) 읽기 전용
Returns the effective type of the connection meaning one of 'slow-2g', '2g', '3g', or '4g'. This value is determined using a combination of recently observed round-trip time and downlink values.
NetworkInformation.rtt(en-US) 읽기 전용
Returns the estimated effective round-trip time of the current connection, rounded to the nearest multiple of 25 milliseconds.
NetworkInformation.saveData(en-US) 읽기 전용
trueif the user has set a reduced data usage option on the user agent.
