¹ - Only mobile data connection established with no additional traffic.
² - Data streams between TRB255 and other connected LAN devices created using iPerf.
³ - Load created using md5sum (calculation and verification of 128-bit MD5 hashes).
Power consumption may differ due to mobile data transmission speed, testing environment and conditions.
