The present invention discloses a wireless communication apparatus having memory sharing mechanism that includes a communication circuit, a memory circuit and a processing circuit. The processing circuit performs the steps outlined below. Remote wireless communication apparatuses are connected to perform channel detection and communication thereon by a communication circuit. Compressed channel state information (CSI) generated by the remote wireless communication apparatuses is received by the communication circuit. The compressed CSI is stored in the memory circuit. Raw CSI is generated according to a status of the wireless channel. When a remaining capacity of the memory circuit is not sufficient, a number of the remote wireless communication apparatuses that the communication circuit performs the channel detection thereon is decreased and the corresponding compressed CSI stored in the memory circuit is removed. The raw CSI is stored in the memory circuit.

Conventionally, Received Signal Strength Indicator (RSSI)-based solutions have been extensively devised in the domains of indoor localization and context-aware applications. These solutions are primarily based on a path-loss attenuation model, with customizations on RSSI processing and are usually regression-based. Further, existing solutions for distance and proximity estimation incorporate data features derived only from the RSSI values themselves with additional features like frequency of occurrence of certain RSSI values thus are less accurate. Present disclosure provides systems and methods that implement a classification model that uses RSSI as well as temporal features derived from the received data packets. The model uses data from multiple devices in different environments for training and can execute proximity decisions on the device itself. The method of the present disclosure monitoring proximity between a plurality of devices implements/uses an effective protocol for decision aggregation to suppress false positive proximity events generated and further stabilizes device's response.

Mechanisms for performance degradation reporting in a microwave system, which comprises a point-to-point wireless microwave link, are provided. A method is performed by a controller entity. The method comprises obtaining classified microwave link data. The classified microwave link data represents microwave link data of the point-to-point wireless microwave link as classified to operating conditions in a set of operating conditions. The method comprises detecting performance degradation affecting data throughput in the microwave system by analysing performance data of the point-to-point wireless microwave link. The method comprises determining, by using the performance data and cause of the performance degradation that attention from an operator entity in the microwave system is required. The cause is defined by the microwave link data as classified to the operating conditions. The method comprises providing an indication to the operator entity only when attention from the operator entity is required. The indication is an indication of the performance degradation and the cause of the performance degradation.
