This　paper　proposed　a　remote　health　monitoring　system　for　the　elderly　based　on　smart　home　gateway.　The　proposed　system　consists　of　three　parts:　the　smart　clothing,　the　smart　home　gateway,　and　the　health　care　server.　The　smart　clothing　collects　the　elderly＇s　electrocardiogram　(ECG)　and　motion　signals.　The　home　gateway　is　used　for　data　transmission.　The　health　care　server　provides　services　of　data　storage　and　user　information　management;　it　is　constructed　on　the　Windows-Apache-MySQL-PHP　(WAMP)　platform　and　is　tested　on　the　Ali　Cloud　platform.　To　resolve　the　issues　of　data　overload　and　network　congestion　of　the　home　gateway,　an　ECG　compression　algorithm　is　applied.　System　demonstration　shows　that　the　ECG　signals　and　motion　signals　of　the　elderly　can　be　monitored.　Evaluation　of　the　compression　algorithm　shows　that　it　has　a　high　compression　ratio　and　low　distortion　and　consumes　little　time,　which　is　suitable　for　home　gateways.　The　proposed　system　has　good　scalability,　and　it　is　simple　to　operate.　It　has　the　potential　to　provide　long-term　and　continuous　home　health　monitoring　services　for　the　elderly.
