Assignee:

International Classification:

H04J 306
H04J 324

US Classification:

3701051

Abstract:

In a wireless TDMA network a control module (CM) sends a time stamp relative to the beginning of its frame in a synchronization packet allowing each of a plurality of user modules (UM) to maintain synchronization relative to the CM. The CM uses a plurality of directional antennas and transmits the synchronization packets over each antenna over a predetermined number of frames. The UMs use a receive time stamp to identify the beginning of a received synchronization packet. The difference between the time stamps combined with a delay constant is used by the UMs to adjust time synchronization to the CM frame.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04J 326

US Classification:

370 852

Abstract:

A CM (105) receives requests for data transfer from a series of UMs (101-103) and from an EM (104). The requests contain the UM (101-103) or EM (104) address and the size of the data packet to be transferred. The CM (105) processes the requests on a FIFO basis, stores the requests in a queue and schedules either a small data channel (415) or a large data channel (420), depending on the packet size to be transferred, an acknowledgement channel (425) and also the corresponding number of required timeslots. The CM (105) picks the first request off the queue and sends a grant to the particular UM (101-103) or EM (104) which receive the grant and immediately access either the assigned small or large data channels (415, 420) in the required number of timeslots and the acknowledgement channel (425).

International Classification:

H04B 700
H04B 1702
H04Q 700

US Classification:

342367

Abstract:

An antenna selection technique is used in an RF communincation system in which user modules (UM) communicate with at least one node. The UM's and nodes each have multiple antennae. The combination of each UM and node antenna is evaluated at the UM. Based on at least signal quality, the UM selects its antenna and the best node antenna for use. An alternate antenna is selected if a person is determined to be present in a predetermined area adjacent a UM corresponding to a predetermined RF power level.

Abstract:

An antenna selection technique is used in an RF communication system in which user modules (UM) communicate with at least one node. The UM's and nodes each have multiple antennae. The combination of each UM and node antenna is evaluated at the UM. Based on both signal quality and strength, the UM selects its antenna and the best node antenna for use.

International Classification:

H04L 1256

US Classification:

370 941

Abstract:

A hierarchical addressing technique is employed in a packet communications system to enhance flexibility in storing and referencing packet information. This method permits packet message data and certain packet control data to be stored in memory locations without having to be duplicated at a different memory location prior to transmission of the packet. This method is preferably employed in a ring configuration in which a series of packets have addressing mechanisms which points sequentially to each other to form a ring of packets received or to be transmitted.

International Classification:

H04B 1713

US Classification:

375202

Abstract:

A method for handing off user devices (131-134) between network control processors (110, 120) in a frequency hopping communication system (100) includes establishing a set of synchronization frequencies (A-D) for use by said NCPs (110, 120), informing the plurality of user devices (131-134) of said synchronization frequencies (A-D) and assigning a synchronization frequency (A, B, C or D) to each respective NCP, each NCP transmitting synchronization information at its assigned synchronization frequency (A, B, C or D) during each hopping dwell (1-82). Upon a determination that a user device hand-off is necessary, said user device in question (133) tunes to a synchronization frequency (B) different from the synchronization frequency (A) employed by the currently serving NCP (110) and synchronizes its operation to the NCP (120) transmitting synchronization information on the tuned to synchronization frequency (B).
