Reliabilitas Sistem Transfer Data Nirkabel Pada ALIX3d2 Untuk Stasiun Cuaca

The data transfer between node wireless weather station running in real-time manner using frequency band 2,4GHz. Those nodes are separated within 2,18 Km and have some obstruction between both link. This data transfer using point to point wireless link is well proven to accommodate Communications traffic from one node which attached to the SBC based Alix3d2 weather sensors to another node which connected to the database server. From analysis of real test bed we obtained that the System Operating Margin (Rx Signal Level – Rx Sensitivity) 43,01dB is sufficient for the system to work well even in such extreme weather condition
