AR509 LTE cannot working normally.

After I looked at the cause of the problem, I realized that the 4G signal of the location where the client device is stored is weak. After the customer places the device on the window and restarts the 4G module, the signal can be received normally. It's easy to ignore this, thank you for sharing, This post was last edited by Mark.hu at 2018-10-31 06:08.

Different from a traditional 3GPP network, an LTE network uses the single-layer architecture that combines radio network controller (RNC) nodes and NodeB nodes into E-UTRAN NodeB (eNodeB) nodes, as shown in Figure 1. The eNodeB nodes complete circuit switching on the base stations. This single-layer architecture simplifies the network, shortens the system delay, and reduces the costs in network construction and maintenance.

This manual is only a reference for you to configure your devices. The contents in the manual, such as command line syntax, and command outputs, are based on the device conditions in the lab. The manual provides instructions for general scenarios, but do not cover all usage scenarios of all product models. This post was last edited by littlestone at 2018-10-31 05:49.

can you share more information about this

Radio Information.

Current Bands : AUTO

Current RSSI = -87 dBm (weakl)

Current RSCP = -84 dBm

Current ECIO = -8 dB

Bands supported :

GSM: GSM850 GSM900 GSM1800 GSM1900

WCDMA: WCDMA850 WCDMA900 WCDMA2100 WCDMA1900

FDD LTE: B1 B2 B3 B4 B5 B7 B8 B20

Modem Security Information.

why 87 is weak , then what's will stronger ?

. Thank you very much for your post. Hope you can update continue like this , thank you very much .
