Aggregation using iPhone as data source?

It is possible to use an iPhone with an RBK853 router to supplement your internet connection in certain circumstances, but it may not be the most reliable or efficient solution.

First, you would need to use a Lightning to Ethernet adapter to connect your iPhone to the router. This would allow the iPhone to act as a secondary WAN connection for the router.

However, it's important to note that the RBK853 router's WAN aggregation feature is designed to combine multiple wired internet connections, such as cable and DSL, into a single high-speed connection. Using a cellular data connection from an iPhone is likely to be slower and less stable than a wired connection.

Additionally, most cellular providers have data usage limits and may charge extra fees for using your phone as a hotspot. This means that using an iPhone as a secondary WAN connection could be expensive if you use it for extended periods of time or for data-intensive activities like streaming or gaming.

Overall, while it is possible to use an iPhone as a secondary WAN connection with an RBK853 router, it may not be the most reliable or cost-effective solution for supplementing your internet connection. It may be better to consider alternative solutions like a backup DSL or cable connection if you need a more reliable backup internet connection.
