This research proposes the development of a portable and user-friendly doorbell notification system specifically for the hearing impaired based on the concept of wearable technology. The design is based on two parts which are the doorbell which acts as the transmitter and the wearable which acts as the receiver. Network performance testing was done on both doorbell and wearable in a house. The test was done to observe and record the state of functionality of wearable in a house using different data transmission rate on nRF24L01s. This research has proposed the development of a mobile and user-friendly doorbell notification system specifically for the hearing impaired based on the concept of wearable technology. Network performance tests were performed on both wearables and doorbells to test the effectiveness of the developed system based on its indoor use. The tests performed were observed and recorded based on indoor wearable functional conditions using different data transmission rates on nRF24L01s. Based on the analysis of the data collected, the interpretation that can be given is that the higher the data transmission rate, then it is found that the higher the total number that needs to be pressed on the doorbell to ensure that the signal can be reached by wearables. Additionally, it also assumes that no matter how far the distance range between the doorbell and the wearable is, the response time remains the same which was 0.8ms for 250Kbps data transmission rate in the all the tested rooms. For 1Mbps and 2Mbps, the wearable can only receive signal until the living room which is 5 meters from the front door and stop receiving signal and cannot function even after the doorbell was pressed after passing the living room. While the results also showed that the distance did not influence the response time of the wearable after the doorbell was pressed when using 250Kbps.
