Essentially, keeping Bluetooth enabled on your phone at all times opens you up to 4g Bluetoothpotential hacks, abuse, and privacy violations. The solution is simple: Don't use it. Or, if you must, make sure to turn it off as soon as you've unpaired from the device in question.
Bluetooth technology offers convenience - from hands-free phone calls to wireless 4g lte iotfile-sharing to playing music on a vehicle's speakers. But leaving your Bluetooth on all the time can be dangerous, and hackers are exploiting the technology to access private information, spread malicious software and more.
Bluetooth is a wireless technology that uses a radio frequency to share data over a 4g volteshort distance, eliminating the need for wires. You can use Bluetooth on your mobile device to share documents or to connect with other Bluetooth-enabled devices.
How can Bluetooth interfere with WiFi ? Both WiFi and Bluetooth may work on the same, 2.4 GHz frequency. Bluetooth is designed to work on 2.4 GHz and also most popular WiFi routers (e.g. TL-WR845N which I have) are configured to broadcast their signal on the same frequency by default.
With LTE-M and NB-IoT at the low end and cellular speeds under 1 Gbps in the middle, 4G LTE is unquestionably the best option in terms of price, availability, and coverage. The upper end, where cellular speeds exceed 1 Gbps, is where 5G might become more alluring, but at a cost.
The cornerstone for developing mobile voice and communication services for packet switched 4G, Wi-Fi, and 5G networks is VoLTE (voice over LTE). Using the IP Multimedia Subsystem, it is the standard mobile network technology for allowing worldwide compatible voice and communication services (IMS).
The 4G LTE type will enable the device to have its own internet connection while the Bluetooth model will only communicate with the phone. Whether it has 4G LTE will be indicated in the specifications.
How Does LTE Function? Large data packets are transferred over LTE to an IP system (IPS). Data was previously moved using the Global System for Mobile Communications (GSM) and Code-division multiple access (CDMA), but only in small amounts.
