OnCell G3111/G3151-HSPA Series Introduction to Serial Port Operation Modes
A-8
Types of UDP Connection
1. Fixed Public IPs for both OnCell and Host PC.
If your cellular service provider offers a fixed public IP address after you connect to the cellular network,
you can access the OnCell G3111/G3151-HSPA from a host PC that has a fixed public IP.
2. Domain name with DDNS.
If your cellular service provider assigns a public IP address after you connect to the cellular network, you
can also access the OnCell G3111/G3151-HSPA using the domain name. If your service provider assigns a
public IP address (either fixed or dynamic) to your cellular device and your control center is the side that
initiates the connection, you can enable the DDNS function and UDP mode to allow other devices on the
Internet to connect to your device using its domain name. This will ensure that your device will remain
reachable even when its public IP address is updated. Note that you will need to register your device with
a DDNS server. Refer to Appendix C for more information.
