Channel bonding is primarily used to increase wireless throughput by:

• A. Reducing interference by blanket signal tiling
• B. Combining adjacent channels to boost data rates
• C. Encrypting wireless traffic for security
• D. Measuring the absolute signal strength of an antenna

Answer: (B)

Channel bonding increases wireless throughput by combining adjacent channels into a wider channel, which lets more data be transmitted in the same amount of time. By widening the channel (for example, 20 MHz to 40, 80, or even 160 MHz in modern Wi‑Fi standards), the physical data rate can rise, boosting overall throughput when conditions permit. This approach relies on both ends supporting the wider channel and having enough spectrum available; otherwise, performance can suffer due to more interference or fewer non‑overlapping channels. The other options don’t describe this mechanism—bonding isn’t about reducing interference with tiled coverage, encrypting traffic, or measuring signal strength.
