Consider the following statements about Bluetooth Technology:
I. Bluetooth is based on a standard maintained by the Bluetooth Special Interest Group (SIG).
II. It operates in the unlicensed 2.4 GHz band.
III. The bandwidth ranges from 1 to 24 Mbps (depending on the version).
Which of the above statements are correct?

Correct option is C

• Statement I: Correct
– Bluetooth standards and interoperability specifications are managed by the Bluetooth Special Interest Group (SIG) which includes major tech companies.
• Statement II: Correct
– Operates in the globally unlicensed ISM band at 2.402 – 2.480 GHz, using frequency hopping for interference reduction.
• Statement III: Correct
– Bandwidth varies by version:
• Bluetooth 2.0: approx. 3 Mbps
• Bluetooth 3.0 + HS: up to 24 Mbps
• Bluetooth 4.0/5.0 improve energy efficiency and range
• Hence, all three statements accurately describe Bluetooth technology.
