LTE5398-M904 - LTE Module upgrade

From Quectel support

Buongiorno
is the update package for europe?

Thank you

Hello Guys,

You can find the last firmware and lte module update on the zyxel link at the end of my post. I have done the update last night :

• firmware update from V1.00(ABQV.3)C0 to V1.00(ABQV.4)C0

• lte module from EG18EAPAR01A08M4G to EG18EAPAR01A12M4G

After the upgrade, I have noticed:

• better aggregation : continuous network band aggregation now (previously aggregation was only available during high download). For information on my location: I have only access to 2 LTE bands (B3 & B20) with my operator. I use a 4G antenna in the attic of my house (LowcostMobile PAN5G-MIMO-2021).
• no significant increase in network speed, but network speed is more consistent (I suppose due to better band aggregation).
• no improvement on VoLTE mode : during a call with an analog phone plugged on RJ11 port, the router switch from LTE-A to UMTS. Therefore, users have internet access at 3G speed when another user is engaged in a phone call.
