The main difference between Wi-Fi and Bluetooth is how these technologies connect with different devices. While Bluetooth is designed to offer short-range wireless communication between two devices, Wi-Fi allows you to connect devices to the internet via a wireless router.
In general, Bluetooth is better for mobile devices that have limited power requirements. Meanwhile, WiFi is better for larger, more stationary devices that need a direct connection to the Internet.
Windows, Android, Linux and iOS have been vulnerable to BlueBorne in the past. Millions could still be at risk. So, yeah, turn off Bluetooth if you're not using it or if you're near anyone you don't trust.
Both WiFi and Bluetooth are wireless technologies that are widely used to send and receive data wirelessly using radio signals. WiFi is for high-speed Internet access that connects nearby devices with each other and share the Internet via hotspots, whereas Bluetooth is used for connecting devices in short range.
Turn Bluetooth off when not in use. Keeping it active enables hackers to discover what other devices you connected to before, spoof one of those devices, and gain access to your device. If you connect your mobile phone to a rental car, the phone's data may get shared with the car.
'Your Wi-Fi router doesn't require rest like other devices. It is designed to be working 24/7 and that's every single day of the year. Whenever you turn your router off, it can automatically send signals to your internet provider,' he explains. 'This works as a signal that your internet connection is unstable.
Using a Bluetooth connection, you can use third-party devices such as wireless keyboards, headphones, speakers, car kits, game controllers, and more with iPad.
WiFi-Only iPad
A WiFi-only model iPad connects to the Internet using wireless or WiFi access. This means when you are in a location without WiFi you cannot get on the Internet, make phone calls/Skype/Facetime, send/receive email and some Apps that rely on Internet access will not work.
You will need some wireless means to get onto the Internet, send/receive email, use video caling services and anything else that needs/requires access to the Internet.
While Bluetooth is beneficial for many applications, be careful how you use it. My advice: Turn off Bluetooth when you're not using it. Keeping it active all the time makes your device more discoverable. As a bonus, keeping Bluetooth off will increase your device's battery life.
Needless to say, it's highly recommended you LEAVE Bluetooth ALWAYS ON if you want to have a smooth & flawless user experience offered by any smart device. And it's with no doubt that they won't drain your battery as the BLE consumes only 0.01-0.25w with a data transfer rate of 200kbps.
No, it is not bad. The Retina display is made of a burning oxide gas. It's not like a Plasma or LED tv where images can get burned into the screen. I just suggest shutting it down at night to let the device “breathe”.
Connections. With Bluetooth, you can connect up to seven devices together in one personal area network (PAN). WiFi doesn't have the same limitations, but how many devices a WiFi network can handle will be largely determined by the bandwidth of the router you connect to.
Advantages of Bluetooth
Bluetooth can connect devices from point-to-point and probably better on security than Wifi, as it can cover shorter distances. In addition, Bluetooth offers an optional two levels of password protection.
Bluetooth and WiFi are both wireless technologies for connecting your devices, but they are quite different. While WiFi is mainly used to connect your devices to the internet, Bluetooth is only used to connect your devices to each other.
Wifi means you can only access the Internet when the device is connected to a WiFi network. WiFi/cellular means you can connect to the internet via WiFi or add a cellular account to the device (like you have on your cell phone) and use the internet anywhere you have cell service.
Ability to access other devices connected to your network, for example, multiple computers can use one printer without a directly wired connection. Access to the Internet on devices like smartphones and tablets to download books, music, movies and apps, or surf the web.
You can make and receive calls on your iPad by using Wi-Fi Calling to relay phone calls through your iPhone (iOS 9 or later required). Cellular charges may apply. Wi-Fi Calling is not available from all carriers.
People no longer need to worry about tripping over cords as they run! Instead, wireless earbuds deliver music from the phone that's in their pocket. Bluetooth comes standard on many other gadgets, including laptops, printers, and TVs. However, the technology has one major limitation.
Make sure that your Bluetooth accessory and iOS or iPadOS device are close to each other. Turn your Bluetooth accessory off and back on again. Make sure that your Bluetooth accessory is on and fully charged or connected to power. If your accessory uses batteries, see if they need to be replaced.
Bluetooth technology allows devices to communicate with each other without cables or wires. Bluetooth relies on short-range radio frequency, and any device that incorporates the technology can communicate as long as it is within the required distance.
Crucially, switching off your WiFi overnight is also a bad idea for security purposes. Ernest added: “Keeping your device on 24/7 means providers can install important security and software upgrades anytime, which they will often do overnight when the network is less busy.”
You may need to reboot once a month or as often as every day. Depending on your internet usage, you may be able to stretch out to every couple of months. You want to consider rebooting your router when you experience slow or no internet connections, need to troubleshoot issues, or want to update your firmware.
