CompTIA Mobility+ MB0-001: Over The Air Technologies

This course is included in our On-demand training solution.


Mobile devices rely on different forms of wireless communication for connectivity and functionality. From cellular technologies for Internet connectivity anywhere in the world, to WiFi networks in the home or office, or personal networks of peripherals using Bluetooth, all these technologies are underpinned by the same set of fundamental principles of radio frequency signaling. This course covers wireless technology from the radio wave up, encompassing all types of wireless connectivity that wireless devices rely on. This course is one of a series of courses that cover the objectives for CompTIA Mobility+ (MB0-001).

Target Audience

IT support personnel, mobility architects, network and security administrators, and anyone looking to gain technical skills for managing mobile devices
