Networks for an e-Healthcare system are designed and developed in this paper. One is the wireless communication network and the other one is the social network. In the wireless network, a wearable e-healthcare system communicates with a person's phone, a data storage system in a hospital, and/or a caregiver computer. This e-healthcare system named LittleBIT consists of a Simblee module, a pedometer, heart rate sensor, and a temperature sensor. Through this wireless communication network, we or our healthcare professionals are able to get our health information. Through this wireless communication network, our doctors or care-givers can assist in our well-beings. In addition, we design and develop another App for people with same or similar health interests to form a social network of LittleBITs. In order to cover people's most popular interests in the App, surveys are done to get feedback about the health metrics or interesting social topics we need to include in our App. The results of this project definitely provide references for the practices of e-healthcare systems for homecare and social health networks.
