摘要： The invention relates to a method in a wireless data transmission system (1) which comprises wireless terminals (MT1-MT4), at least a first access point (AP1) and a first access point controller (AC1), a second access point (AP2) and a second access point controller (AC2). In the data transmission, data frames are used. In the invention, two allocation strategies are defined of which two are selected at a time. From the data frames, a first starting point (TS11, TS21) and a second starting point (TS1n, TS2n) are determined. In order to select a strategy, it is examined whether there is other traffic on the channel. If other traffic can be detected, it is examined which allocation strategy is selected, and an allocation strategy which is different from that of the examined connection is selected for the connection to be set up. However, if traffic is not detected, it is possible to select the allocation strategy freely. In the first allocation strategy, the allocation of the time slots of the data field (D1, D2) is started from the first starting point (TS11, TS21) of the data field, and in the second allocation strategy, the allocation of the time slots of the data field is started from the second starting point (TS1n, TS2n) of the data field.

摘要： The invention relates to a method for selecting an access point in a wireless communication system comprising mobile terminals and access points. To enable the mobile terminals to take into account the prevailing conditions within the entire coverage area of an access point more effectively than before, sets of attributes are sent from mobile terminals to the currently serving access point, each set to contain at least one attribute indicating the quality of a wireless link between the serving access point and the sending mobile terminal. Based on the sets, a service report describing current service conditions in the coverage area of the access point is formed and transmitted to at least one mobile terminal. This terminal examines the service report of at least one access point and, based on the examination, selects the access point to which a wireless link is to be established.

摘要： A method and an apparatus for controlling release of a hoisting motor brake in a hoisting apparatus, where electricity is used as the driving force and a squirrel cage motor as the hoisting motor for hoisting or lowering a load attached to a hoisting member of the hoisting apparatus. Controlling of brake release comprises measuring the current and supply voltage of the hoisting motor after the start-up period of the hoisting motor and determining a variable which describes the load of the hoisting apparatus from the current and supply voltage. The variable describing the load is compared with a pre-determined limit value and hoisting or lowering of the load is interrupted if the variable describing the hoisting apparatus load exceeds the limit value set for the hoisting movement when the load is hoisted or if it exceeds the limit value set for the lowering movement when the load is lowered.
