Why does a Wi-Fi client roam from one AP to another?
There are many reasons why a client will roam from one AP to another, the most common one being when a client moves from the radio frequency (RF) boundary of one AP to another AP. Healthcare environments are often very challenging from an RF planning standpoint, due to their physical structure, with long hallways, isolated patient rooms, and shielded radiology areas. These physical challenges can create abrupt transitions between AP coverage areas and inhibit fast and efficient roaming performance. With the strict performance and availability requirements of medical devices, significant emphasis on establishing a robust and reliable Wi-Fi network is important.
