Abstract: Techniques for destination domain extraction for secure protocols are disclosed. In some embodiments, destination domain extraction for secure protocols includes monitoring network communications between a client and a remote server; determining if the client sends a request to create a secure connection with the remote server (e.g., in which the network communications are initiating a setup for a secure protocol-based connection); and extracting a destination domain from the request to create the secure connection with the remote server. In some embodiments, the secure protocol is a secure sockets layer (SSL) protocol or transport layer security (TLS) protocol, and the destination domain is extracted from the server name indication (SNI) of a client hello message sent from the client to the remote server. In some embodiments, destination domain extraction for secure protocols further includes applying a policy (e.g.

Abstract: Systems and methods are disclosed for listening window adjustments for power savings in BLE (Bluetooth low energy) communications. BLE devices determine time differences between assumed transmission times and actual receive times for packets transmitted by another BLE device. The BLE device then adjusts a listening window using the time differences, for example, to reduce the size of the listening window based upon the time differences. The adjusted listening window is then used by the BLE device to listen for and receive additional packets from the other BLE device.

Abstract: A system is described for forming an estimate of an unwanted signal component that may be formed as a result of non-linearities in a system. The estimate is used to form a cancellation signal which is added to an input signal to reduce the influence of the unwanted component.

Abstract: Disclosed is a method performed by a base station system of a wireless communication network, for increasing signal quality of signals sent from a radio head (RH) to a radio unit (RU) over a metallic conductor. The base station system comprising a baseband unit (BBU), the RU, and the RH, and the RU is connected to the RH via the metallic conductor.
