Mr. David has multiple apps in his smartphone in which some are interested in using Wi- P2 Fi signal. At certain point, when the Wi-Fi signal is turned off, those apps will change their state, but they are interested to know when the Wi-Fi signal will back on. Instead of the apps constantly checking whether the signal is on or off, the system will inform when the Wi-Fi signal is back on. So, the interested apps need to register to receive notification message regarding Wi-Fi signal as the system will broadcast the message.
