- ikiris 3y agoHow is multipath going to tell radios how to roam between cells?
- mlyle 3y ago"Back to cell service" --- you probably have radios connected to both wifi and to the cellular network. It's not the same radio. Then you need to decide what links to send frames over (and how). MPTCP is one approach to this.
- ikiris 3y agothis is a terrible solution to anything except guest wireless networks
- mlyle 3y ago? I'm not sure you understand. If you have a device that can use cellular and wifi, it has to figure out when it should be sending packets over wifi, or when it should give up and send packets over cellular. MPTCP isn't mature or a good approach for this yet (and may never be), but it could present a way to smoothly roam between wifi and cellular. Imagine walking across a big campus, and having your device keep a network connection up seamlessly as you lose wifi between buildings. Whether solved via overlay networks, or a clientside protocol like MPTCP-- this is a service networks should provide. Unfortunately, we've got no way to roam except within a single network (wifi roaming; satellite handoff; cellular handoff).
- cryptonector 3y agoSee u/mlyle's answer. There is no way that 802.11X can address this because the cell network and Wi-Fi APs are fundamentally different link layers, with very different access protocols. Even if they were the same, roaming within an administrative unit (e.g., an office) is very different from roaming between networks administered by different entities, and will require different protocols.
