EByte e70 very Low sensitivity

[Elkez]

I noticed that the E70 module has a very low sensitivity (-110 dBm).
At the same time, this is a relatively new product.

Hi,
yes, it’s quite impressive, and I start some penetration test and I notice that 4/5 wall (with meet iron) can’t block the signal.

Hi Renzo
I will be glad if you publish the test results of this module. I don’t think the E70 has a range of 1.5 km with that power and sensitivity.
A range of approx. 500 m would be enough for me, but there are obstacles on the route (trees, buildings, cars, etc.)

One request for you, Renzo.
I’m all over the new and new wireless modules.
It is not enough for me to order, assemble and test a single module and there is another, better, faster, more energy efficient, etc. I am not enough to follow the development and I no longer have the strength to constantly try something new.
I need to make a simple device: 2 transmitters that would signal 2 states. On Off. The transmitters will be battery powered. A good addition would be a signal strength measurement (RSSI).
Based on your experience, can you recommend a module that would meet these simple conditions? Range approx. 500m with various obstacles (wall, cars, people, trees), in short, normal outdoor traffic.
Thanks for your willingness.

Hi Elkez,
I normally describe a device module thinking of a real scenario (I don’t write to have a visit), and I select the e70 because it has RSSI and a very good Sleep mode management to manage the battery. You probably never raise a distance if a device is declared for 1.5km but has high sensitivity.
All to say, this can be considered a good solution.
There are alternatives, but the efficiency can’t be the same.

But in your case (low number of messages per second), I think it can be a good solution for a LoRa device like the e220.

Bye Renzo
