Checking RSSI on the HTC EVO 4G

This week we are going to show you how to check the RSSI for 1xRTT, EVDO/3G, and WiMAX/4G on your Sprint EVO 4G! RSSI is a numerical measurement of signal strength, which is much more exact than the "signal bars" most users are accustomed to. Knowing your RSSI can be extremely helpful, particularly if you're trying to determine whether a signal booster will help you (for more information on RSSI, check out our article on Received Signal Strength Indicator.)

To view RSSI on your EVO, follow these steps:

1. First open the phone application, dial ##33284# and press "call"

2. This will bring you to "Field Trial" mode as shown below. Select the network that you want to see signal information for.
    "1X Engineering" = 1xRTT [2G Voice/Data Network]
    "EVDO Engineering" = 3G Mobile Broadband Network
    "WiMAX Engineeering" = 4G High Speed Network

Field Trial Mode

3. Look for "Rx Power" which will show you RSSI numbers for your signal quality as shown below.

To exit the field trial mode, simply press the Home button on your EVO.
