What key technology uses a Bluetooth connection?

This is in the globally unlicensed (but not unregulated) industrial, scientific and medical (ISM) 2.4 GHz short-range radio frequency band. Bluetooth uses a radio technology called frequency-hopping spread spectrum.

Which encryption protocol below is used in the WPA2?

AES-CCMP is the answer.

What type of radio frequency transmission are used by Bluetooth?

Bluetooth is a short-range wireless communication technology standard. Bluetooth uses short-wavelength UHF radio waves of a frequency range between 2.4 and 2.485 GHz.

What device acts like a wireless base station in a network acting as a bridge between wireless and wired networks group of answer choices?

A WAP can operate as a bridge connecting a standard wired network to wireless devices or as a router passing data transmissions from one access point to another.

Is Bluetooth PAN or LAN?

Bluetooth technology allows the sharing of voice, data, music, photos, videos, and other information wirelessly between paired devices. Bluetooth technology functions as either a LAN or a PAN.

What is Bluetooth and its types?

From a technical perspective, there are essentially three different types of devices: “Classic” Bluetooth, Blue- tooth dual-mode and Bluetooth single-mode. The first is the “classic” Bluetooth device as mentioned earlier. These are typically those devices that need a maintained and often high-throughput connection.

What secure protocol is recommended for time synchronization?

Contributing to a More Secure and Trustworthy Internet through Open Standards. Network Time Protocol ( NTP ) is one of the oldest Internet protocols in use. It enables the synchronization of clocks on computer networks to within a few milliseconds of standard universal coordinated time (UTC).

Which technology is predominately used for contactless payment systems?

NFC technology powers contactless payments via mobile wallets like Apple Pay, Android Pay, as well as contactless cards.

What term below is used to describe an attack that sends unsolicited messages to Bluetooth enabled?

Bluetooth devices are not backward compatible with previous versions. What term below is used to describe an attack that sends unsolicited messages to Bluetooth enabled devices? Bluejacking. An evil twin AP is an AP that is set up by an attacker to mimic an authorized AP​, with the intent to redirect client devices.

Which is better Bluetooth or RF?

Bluetooth is safe. It utilizes radio signals 1000 times weaker than the standard wireless technologies used by mobile phones. It is secure too, so once a connection has been made no-one can listen in and there is no interference from other Bluetooth devices either.

Is Bluetooth the same as RF?

Radio frequency ( RF ) is a data transmission technology which is based on electromagnetic radio waves. Bluetooth (which is a type of RF ) is an open wireless technology standard for transmitting data over short distances. It uses radio waves on a particular frequency for data transmission from device to device.

What kind of frequency is Bluetooth?

Frequency. Bluetooth only does its work on a 2.4GHz frequency, whereas many WiFI networks these days will run on both 2.4GHz and 5GHz frequencies.

What is the maximum range of most Bluetooth 5 Devices Group of answer choices?

The Bluetooth 5 spec allows low-energy transmissions to sacrifice data rate for more range. A lot more range: up to four times the range of Bluetooth 4.2 LE, for a maximum of around 800 feet.

What device acts like a wireless base station?

Calculate the Price

The current Bluetooth version is Bluetooth 6. B. False
What device acts like a wireless base station in a network, acting as a bridge between wireless and wired networks? A. Access point


What is the maximum range of most Bluetooth devices?

The range of the Bluetooth ® connection is approximately 30 feet (10 meters). However, maximum communication range will vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment. NOTE: Not all audio devices are supplied with Bluetooth capability.
