Wireless RS232 modules

[joseph]

Hi ,

Can anyone suggest to me any long range wireless RS232 modules?

I need them for a telemetry system. The speed doesnt need to fast
(19kbit) will do but range is important.

Thanks a lot

Joseph

How much range do you need ???
Hoe much long will data need to be sent ??
How big of a battery can you install ??
How long do you expect the battery to live ??

The attached will give you all the range you will ever need.

This is not a binaries newsgroup. You can post it to
by attaching it as a GIF, JPEG,
or other common image file. Then, post a message here giving the name
of the post. If you try to post a binary file here, most people will
never see it.

It's difficult to make a recommendation ... not enough data.

What is your desired range?
What is your antenna height at Tx and at Rx?
Are the Tx and Rx both stationary or are one or both of them mobile?
Are you restricted to the frequency band you can use?
What is your error rate requirement?

Hi,

i was thinking about 500m in an urban enviroment with one station in a
fixed postion and the other being mobile. For the fixed station
antenna rquirements are not critical but for the mobile station a
lightwieght antenna is preferred.

Regarding the arror the overall data rate will be rather slow since
this is a telemetry system so i settle for 1/10000 or better.
