What technological capability is necessary for telehealth communication?

A stable internet connection is essential for telehealth communication because it ensures that audio and video data can be transmitted in real-time without interruptions or delays. Effective telehealth services rely on seamless interactions between patients and healthcare providers, which depend heavily on the quality of the internet connection. A stable connection minimizes issues such as lag, buffering, or disconnects that could hinder the consultation process, potentially affecting the quality of care provided.

The other options represent technological elements that may support telehealth but are not strictly necessary. For example, a high-definition television screen may enhance the video experience, but it is not a requirement; a standard computer or mobile device with a functional screen can suffice. Desktop computers are not the only device option available for telehealth; laptops, tablets, and smartphones can also be utilized effectively. Lastly, wireless internet should always be secured; relying on an unsecured connection exposes sensitive health information to potential breaches, which is contrary to best practices in telehealth.
