1.Overview
1.1 introduction
E30-490T20S is based on originally imported SI4438 fro m
Silicon Labs, with transparent transmission available, TTL level
output with air wake-up function, WOR (ultra-low power
consumption). They feature half duplex and SMD interface. 490M
frequency, long wave length and strong ability of penetration and
diffraction. They are applicable in the industrial and living
environment like a plant or indoors.
The module features FEC (Forward Error Correction )
algorithm, which ensure its high coding efficiency & good correction
performance. In the case of sudden interference, it can correct the interfered data packets proactively, so that the re liability
& transmission range are improved correspondingly. But without FEC, those data packets can only be dropped.
E30-490T20S strictly follows design standards of FCC, CE, CCC and meets various RF certification requirements
for exporting.
