  • Publication number: 20250048177
    Abstract: In one embodiment, a method for achieving zero packet loss in wireless roaming is implemented by a processor of a wireless client device in a system. The wireless client device establishes a first data plane in association with a first radio connected to a first access point and a second data plane in association with a second radio. The first data plane is different from and operates concurrently with the second data plane. The wireless client device determines a second access point by scanning a plurality of operating channels using the second radio. The wireless client device synchronizes the second data plane with a network controller to connect the second radio with the second data plane to the second access point. The wireless client device switches traffic of the first data plane connected to the first access point to the second data plane connected to the second access point.
