# Rssi indication using AT+WSCAN

## Question

Asked by anglial on 2014-09-08 in Wireless.

I am writing some code to process the results of command AT+WSCAN

What is maximum and minimum value of RSSI that could be in the response ?
Is that the same for all firmware versions - I am using 1.0.1.8

Hello Anglial

Regarding RSSI, there is no maximum and minimum value.

But, WizFi250 regards it as below.

```
    ~ -80  : Very Poor
-80 ~ -70  : Poor
-70 ~ -68  : Good
-68 ~ -58  : Very Good
-58 ~      : Excellent
```
