Offloading to Wi-Fi
If you are connecting to the network using 3G, 4G or HSPA regardless of the carrier, they use radio state machine to manage the radio resources. On the other hand, Wi-Fi connections are much more efficient than 3G and 4G. For Wi-Fi, there is no need for the state machine. As a developer, you can use this to your advantage.
Although there is less latency for connection setup, many applications fail to obtain this advantage. Offloading to Wi-Fi offers has several benefits, which are as follows:
Lower data cost
Extended battery life
Faster connection
Improved network traffic
Improved customer experience
However, if you use Wi-Fi extensively, it will drain your battery faster than compared to a 3G or 4G data connection. However, if you use it occasionally, the impact will be minimal.
You can use a Wi-Fi connection for the following situations:
If your application requires real-time interaction with the server, Wi-Fi will be the best option.
If you have a heavy data usage application...
