name: OTA
full_form: Over The Air
context: IMD. Receiver requirements With the exception of the receiver spurious emissions (which is TRP like the transmitter spurious emissions) all the receiver requirements are based on receiving a wanted signal at a specified power level, either on its own or in the presence of an interferer. The OTA receiver requirements have 2 types of OTA sensitivity defined: 1. OTA sensitivity - highest gain assumed hence lowest EIS. The Rel-13/14 specification included OTA sensitivity requirement which was based on a declared range of angle of arrivals (RoAoA) for the UL signal. The OTA sensitivity requirement is by BS manufacturer declaration and was intended to capture the effects of the antenna (such as scan loss). Multiple declarations can be made with different EIS values and RoAoA's. One of the declarations will be based on the maximum antenna gain and hence will represent the best case EIS, this value is defined as OTA minimum sensitivity. 2. OTA reference sensitivity - lowest gain assumed hence
description: Over The Air (OTA) refers to a set of parameters related to the receiver requirements in mobile devices, specifically focusing on the sensitivity and performance of the device's antenna system when receiving signals over the air. These parameters include OTA sensitivity and OTA reference sensitivity, which are defined based on the angle of arrivals and the gain of the antenna.
explanation: The context explicitly states that OTA is a set of parameters related to receiver requirements in mobile devices, thus classifying it as a parameter.
