Detailed explanation-1: -Bluetooth devices can create both point-to-point and point-to-multipoint connections. A connection with two or several (maximum 8 devices) devices is a piconet where all devices follow the same frequency-hop scheme. To avoid interference between devices, one of the devices automatically becomes a master of the piconet.
Detailed explanation-2: -Bluetooth® technology uses the 2.4 GHz ISM spectrum band (2400 to 2483.5 MHz), which enables a good balance between range and throughput. In addition, the 2.4 GHz band is available worldwide, making it a true standard for low-power wireless connectivity.
Detailed explanation-3: -Bluetooth Connection Topologies Most Bluetooth LE devices communicate with each other using a simple point-to-point (one-to-one communication) or point-to-multipoint (one-to-many communication) topology as shown in this figure. Devices using one-to-one communication operate in a Bluetooth piconet.
Detailed explanation-4: -Detailed Solution. The correct answer is Wireless connection between various devices/equipment over short distances.
Detailed explanation-5: -Explanation: Bluetooth is a wireless technology used to create a wireless personal area network for data transfer up to a distance of 10 meters. It operates on 2.45 GHz frequency band for transmission.
