What is the antenna type used for location services?

DAS (Distributed Antenna System) is primarily used to extend cellular or high-power RF signals in large venues for coverage, not typically as the direct antenna type for individual Wi-Fi APs performing location services.

'Hybrid' is not a standard, recognized antenna type in the context of specific antenna forms used for location services; it is too vague to describe a particular physical antenna.

Internal antennas, which are often omnidirectional, are commonly used in access points deployed for Wi-Fi location services. These antennas provide wide, uniform signal coverage in an indoor environment, allowing client devices to receive signals from multiple access points necessary for triangulation or trilateration to estimate location effectively.

Yagi antennas are highly directional and are generally used for point-to-point or long-range outdoor links, not for providing the broad, omnidirectional indoor coverage necessary for most Wi-Fi location services that rely on multiple AP signals.
