10.1.5.4 Lab - Mobile Device Information



22.               What is Wi-Fi calling?

23.               Where is Wi-Fi calling useful?


  in areas with poor cellular coverage because it uses a local Wi-Fi hotspot to fill the gaps.

24.               Name and describe 4 types of Mobile Payments:
 Premium SMS based transactional payments - consumers send a SMS message to a carrier's special phone number containing a payment request. The seller is informed the payment has been received and is cleared to release the goods. The charge is then added to the customer's phone bill. Slow speed, poor reliability, and poor security are a few shortcomings of this method.

 Direct Mobile Billing - Using a mobile billing option during check-out, a user identifies him or herself (usually through a two-factor authentication) and allows the charge to be added to the mobile service bill. This is very popular in Asia and has the following benefits: security, convenience, and no need for bank cards or credit cards.

 Mobile Web Payments - The consumer uses the web or dedicated apps to complete the transaction. This method relies on the Wireless Application Protocol (WAP) and usually requires the use of credit cards or a pre-registered online payment solution, such as PayPal.

 Contactless NFC (Near Field Communication) – This method is used mostly in physical store transactions. A consumer pays for good or services by waving the phone near the payment system. Based on an unique ID, the payment is charged directly against a pre-paid account or bank account. NFC is also used in mass-transportation services, the public parking sector, and many more consumer areas.

 Android - After a device is locked, you can unlock it by entering the Gmail account information used to set up the device

IOS -  the device remains disabled for 1 minute. Each failed attempt after six results in additional waiting time


34.               Why is it important to periodically back up data on mobile devices?

40.               What is meant by rooting or jailbreaking and why would you want to do it?


 Rooting and Jailbreaking are two names for removing restrictions and protections added to mobile operating systems. Rooting is the term used for Android devices, and Jailbreaking is used for iOS devices. The manufacturer restrictions are removed from these devices, allowing them to run arbitrary user-code, granting users full access to the file system and full access to kernel modules.






41.               What is meant by “bricking” your device? (you may need to look this up)

 when used in reference to consumer electronics, describes an electronic device such as a smartphone, game console, router, or tablet computer that, due to a serious misconfiguration, corrupted firmware, or a hardware problem, can no longer function, hence, is as technologically useful as a brick.
