Abstract: A smoke generator for anti-burglar purposes comprising canister holding means for holding a canister for chemicals to be used to generate smoke wherein the smoke generator further comprises a smoke deflector arranged below the position of the canister for even distribution of generated smoke, and wherein the smoke deflector have a smoke deflector cavity of sector shape. The smoke generator is provided with a cartridge for the canister to ease replacement of used or expired canister. The smoke deflector is provided with a residual collector to prevent residuals and debris from littering the room where the smoke generator is used.

Abstract: A method and a system of controlling a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes (14; 16; 19; 21; 23) and a first gateway (12) having wireless communication means for communicating with. The method includes installing at least one second gateway (12?; 32) in the home wireless system, broadcasting an identification message from a peripheral wireless node (14; 16; 19; 21; 23) searching for a controlling gateway in a link establishment process, and receiving in each of the first gateway (12) and the at least one second gateway (12?) the identification message.

Abstract: A home wireless system and a method of controlling it wherein the home wireless system comprises a plurality of wireless peripheral nodes and a first gateway having a wireless communication means for communicating with and controlling wireless peripheral nodes.

Abstract: A method and a device for supervising a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes (14; 16; 19; 21; 23), a first gateway (12) having wireless communication means for communicating with and controlling associated peripheral wireless nodes.

Abstract: Jamming detection device (7) and method, which scan one or more frequency bands (201, 401, 402) and, if jamming is detected in said frequency bands (201, 401, 402), transmits an alarm signal through an ultra narrow band network (8). Preferably, both an ISM network (2) connecting a control panel (3) and at least one peripheral (1), and a GSM network (4) connecting the control panel (3) and a back end service (5), are scanned. Also preferably, the ultra narrow band network (8) is implemented over the same frequency band (801) as the ISM network (2) connecting the control panel (3) and the least one peripheral (1).

Abstract: A method of handling inconsistencies in a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes (14; 16; 19; 21; 23), a first gateway (12) having wireless communication means for communicating with and controlling associated peripheral wireless nodes, at least one second gateway (12?; 32), and a Remote Central Monitoring Station, RCMS.
