A method of communication or transmission of data between a first and a second node in a wireless multi-hop network comprises bringing the first node and the second node in a fully operative mode for communication with each other and subsequently bringing the first node and the second node in a reduced operative mode where no communication with any other node is possible and, before bringing the second node in the fully operative mode, bringing the second node in a listening mode during a token listening period to check for presence of a wake-up token from the first node, and thereafter bringing the second node into the reduced operative mode if no wake-up token is received, and bringing the second node into the fully operative mode for reception of data from the first node if a wake-up token is received. This wake-up scheme is a kind of scheduled rendezvous scheme with collision avoidance, and may be called an induced wake-up scheme. It is advantageous because of its low power consumption (no des only wake up completely when a message is present for them to receive) and because of the low latency in data transfer. The wake-up tokens used enable random access to other nodes, nevertheless having a system which is low-power in operation.

Interference classification with minimal or incomplete information. Receivers in access points and in other network devices on a wireless digital network may be switched to a spectrum monitor mode in which they provide amplitude-versus-frequency information for a chosen part of the spectrum. This may be performed by performing a FFT or similar transform on the signals from the receiver. Receivers are calibrated with known interference sources in controlled environments to determine peaks, pulse frequency, bandwidth, and other identifying parameters of the interference source in best and worst case conditions. These calibrated values are used for matching interference signatures. Calibration is also performed using partial signatures collected over a short period in the order of microseconds. These partial signals may be used to detect interferers while scanning. Another aspect of the invention is to record the variation of noise floor in the presence of interference sources. Multiple interference sources may be detected. While data collection is performed in one or more APs, classification may be performed in the

AP or on other systems associated with the network collecting and processing spectrum information from one or more APs.
