Handoff For Users
Both of your devices need to be tied into the same iCloud account. Both of your devices need to be connected to the same Wi-Fi network. Both devices need to have their Bluetooth turned on.
Bluetooth is easier to use and consumes less power than Wi-Fi because it only requires an adapter on each connecting device. WiFi is more secure than Bluetooth. Bluetooth is less secure than other wireless technologies such as WiFi. Wi-Fi allows more devices and users to communicate at the same time.
Bluetooth does not use cellular data — here's how its signals work. To put it simply: no, using Bluetooth won't affect your cellular data in any way. Bluetooth works using short-range radio waves, not an internet connection.
For example, you can start answering an email on your iPhone, then finish it in Mail on your Mac. You can use Handoff with many Apple apps—for example, Calendar, Contacts, and Safari. Some third-party apps may also work with Handoff.
Apple handles handoffs securely, whether from one device to another, between a native app and a website—even handoffs of large amounts of data.
Use Handoff with any Mac, iPhone, iPad, or Apple Watch that meets the Continuity system requirements. Handoff works when your devices are near each other and set up as follows. Each device is signed in to iCloud with the same Apple ID.
Sign in to the Apple ID website (https://appleid.apple.com) and review all the personal and security information in your account to see if there is any information that someone else has added. If you have two-factor authentication turned on, review trusted devices for any devices that you don't recognize.
To see who can track your location, open up the Find My app and tap on the "People" tab. People who have shared their location with you and people you have shared your location with will show up in this list. A person who is able to see your location will be denoted with "Can see your location."
If you backup or synchronize your phone to iCloud then anybody who has the details for that account, or even has their phone connected to the same account (a family member, for example), could potentially see your personal text messages.
Handoff is necessary for preventing loss of interruption of service to a caller or a data session user. Handoff is also called handover.
Handoff can be categorized as hard handoff, soft handoff, and softer handoff. The hard handoff can be further divided into intrafrequency and interfrequency hard handoffs. During the handoff process, if the old connection is terminated before making the new connection, it is called a hard handoff.
Process of transferring a mobile telephone call from one cell to another without dropping the call. Cellular users may traverse several cells during a conversation, sometimes requiring a high-speed handoff in a moving vehicle.
With Handoff, you can start something on one Apple device (Mac, iPhone, iPad or Apple Watch) and then seamlessly pick it up on another. For example, start answering an email on your iPhone, then finish it in Mail on your Mac. You can use Handoff with many Apple apps — for example, Calendar, Contacts, Pages and Safari.
If you use Handoff, private windows aren't handed off to your iPhone, iPad, iPod touch, or other Mac computers. Changes to your cookies and website data aren't saved.
From your Mac to an iOS or iPadOS device: The Handoff icon of the app you're using on your Mac appears on your iPhone (at the bottom of the app switcher) or your iPad or iPod touch (at the end of the Dock).
Handover is when a user switches from one base station to another within the same network operator, while roaming is when a user connects to a different network operator.
In iOS, Handoff works great. The icon appears within seconds, and the handoff is fast. Although you need Wi-Fi turned on, you don't need a Wi-Fi network. After the devices handshake via Bluetooth, the actual transfer happens over a Wi-Fi Direct connection between the devices -- no router or access point.
Handoff is the process of transferring data or call from one mobile network to another or from one channel to another because of node's movement.
You can use Bluetooth without Wi-Fi. In fact, Bluetooth does not need any internet access at all to be set up and used. However, you will find many Bluetooth devices are also capable of connecting to the internet.
Bluetooth allows for short-range data transfer between devices. As an example, it is commonly employed in headsets for mobile phones, enabling hands-free phone use. Wi-Fi, on the other hand, allows devices to connect to the Internet.
For the best experience on your iOS or iPadOS device, try to keep Wi-Fi and Bluetooth turned on.
