The question asks about the latest wireless high-speed search engine, and among the options given, WIMAX stands out as the most relevant answer. WIMAX, which stands for Worldwide Interoperability for Microwave Access, is a technology designed to provide high-speed wireless broadband access over long distances. It enables users to connect to the internet without the need for wired connections, making it a powerful tool for seamless internet access.

Unlike the other options, WIMAX specifically focuses on delivering broadband services wirelessly. Bluetooth is primarily used for short-range communication between devices (like connecting peripherals), while CMOS refers to a technology used in imaging and semiconductor devices, not in internet connectivity. Broadband, while related to high-speed internet, typically refers to the technology rather than a specific wireless method.

In summary, WIMAX is a technological advancement in wireless communication, making it the correct choice for a new high-speed search engine that operates without the need for wires, distinguishing it from the other options provided.
