Re: Wireless cables replacement technology?

Hi,

It sounds like any of the existing RS232-over-wireless products would
probably work for you. Some other things to narrow it down would be
comm range and cost. Google should show you plenty of options.

Also, you mentioned that you want multiple nodes (B-Z) to communicate
with one central point (A), if I understand that correctly? If point A
is a PC or other network-capable device, then some of the RS232-to-
WiFi products might be interesting for you - for example, the
Lantronix WiPort has two serial ports that you can simply telnet into
through the WiFi connection.

Otherwise, if these are just embedded devices, then WiFi is probably
overkill for your needs, and Bluetooth has a somewhat limited range.
That leaves any of the ZigBee or custom protocols, which are just fine
for the baud rates you're looking at.

What data rate and range do you need?

What kind of data are you trying to send? Are you only replacing RS232
connections or are there other, maybe custom, comm protocols?

Are you looking for ready-to-go modules in boxes that you just need to
hook power+RS232 into, small radio modules that require some MCU work,
or would you want to build your own radio+MCU solution?

Right now I'm just investigating, I have almost no solid requirements.
I just want to know what's available. We may buy, we could build, most
likely its async, byte oriented, most likely RS232. The speed would
probably be 4800 - 56k, probably a lot of 9600. All the device would
have AC power.
