Series 1 models are point to point - two radios talking only to each other.
Series 2 models are mesh network - routers pass on messages that they receive that are not meant for them.

Can you use series 1 models for a network? Yes, but YOU have to create the network and know how to get a message from one radio to another, via one or more intermediaries. Far simpler to use the correct models.
