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 base station of a cellular radio system is in radio communication with the mobile stations of the cellular radio system by using mutually essentially orthogonal channels. In order to control the use of the channels, said channels are divided into groups with different priorities, so that the base station uses primarily the channel group with the highest priority. Channels belonging to different priority groups are put to use in a selective manner as a response to the loading of the base station.

摘要： The present invention relates to systems and methods for a implementing an optimized low-end radio communication protocol, wherein the communication link is flexible and the power consumption characteristics are optimized. One facet of the system's flexibility relates to the system's ability to negotiate device control roles associated with a polling communication link. Also, once the device control roles are in place and the communication link is established, the system selectively implements a number of polling protocols for a multitude of applications that need a low power consumption. In some embodiments the system maintains a communication link with a reduced frequency polling protocol. This type of communication link maintains efficient power consumption characteristics, as well as, connection times that are faster than establishing a communication link between disconnected devices.

摘要： According to the proposed method, the frequency of power control commands transmitted on a power control channel is changed according to the traffic. When the traffic becomes slower in at least one direction due to a DTX state, a slower transfer rate, asymmetric data transfer or for any other reason, the frequency of power control commands is lowered. Both the base station and the personal station may lower the frequency of the commands which they send. An alternative to changing the frequency of power control commands is to change the energy of power control bits. The duration of power control bits must hereby be extended, if a standard bit error ratio is desired. If the system is frequency-divided and/or time-divided and uses frequency control command of several bits, the length of the command word may be shortened in addition to or as an alternative to the change in frequency. The power control algorithm may be changed several times during a traffic connection.

摘要： A method and system for establishing a non-frequency-hopping connection link between a slave device with another slave device in a communications network having a plurality of frequency channels within a radio frequency band known as the unlicensed ISM band, wherein the connection links between slave devices are capable of being carried out in a frequency-hopping fashion. The non-frequency-hopping connection link can be established after the channel conditions, including the carrier power of the channel and the interference and noise levels adversely affecting the connection link, are measured.
