the hardware currently used in a recently founded therapy center is a FRITZ!Box 7490 with 2 DECT phones and 1 printer (WIFI) used by 2 therapists computers (WIFI). The therapists work separately and only share the rooms, the printer and the internet connection.
I would like to improve the network security implementing WIFI zones (multi-SSID). So I need multiple WIFI networks (dual band) for each therapist, printers, private cell phones etc. which the Fritz!Box 7490 beside guest WIFI does not provide (but I need the DECT base station). Applications are more frequent video therapy for patients and training of two therapists. The cost could be less than or around 100 euros - there is no need for a ultra high performance device. In the end budget is not the problem. The design should be quite simple, as the device will hang in the corridor next to the Fritz!Box. No physical Ethernet ports are needed due to space and no possibility to install cables.
Currently, I tend to the following devices without any real reasons (just cost, design and relevance)
How many SSID (4 per band?) can I create with these devices? Am I reasonably correct with the devices? Is a device to be preferred for compatibility reasons? Which are good suitable alternatives from my descriptions? I appreticate your answers.
Openwrt is a great project.
