With 4 bars and a clean signal it should work well. I only get 3 bars showing but I go by the cellular metric values to tune up the frequency. I have very good and/or excellent RSRQ and SINR metrics and good RSRP values and the service is actually very reliable for us. I know we have streamed 2-3 concurrent sources from time to time. I have a couple dozen different clients on the LAN and have no problem with service. I don't have IOT devices but that is not my focus. If you have a clean, quality cellular signal it should perform well. Signal strength is great but great RSRQ and SINR metrics tend to improve performance as there are fewer retransmissions as the content is delivered faster and clean with less communication churn. It seems like you have a good signal so that is a great start.
