46944842, Sep 15, 1987

Filed:

Feb 18, 1986

Appl. No.:

6/830145

Inventors:

Frederick G. Atkinson - Winfield IL
Anthony Kobrinetz - Hoffman Estates IL
Barry J. Menich - Chicago IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q 704

US Classification:

379 59

Abstract:

A fixed site station for cellular systems is disclosed. A plurality of radio transceivers are removably disposed in apertures of the common equipment housing and are provided unique parameters of operation by the system controller dependent upon the aperture in which the transceiver is located and the antenna configuration of the cell being served.

Appl. No.:

6/829872

Inventors:

Barry J. Menich - Chicago IL
Frederick G. Atkinson - Winfield IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04B 700

US Classification:

455 33

Abstract:

A method and apparatus for determining which sector antenna of a sectorized cellular radiotelephone system is receiving the strongest radio signal is disclosed. The signal strength of sector antennas is sequentially sampled, converted to digital representations, and stored according to which antenna received the signal. The digital representations are recalled from storage and the strongest signal along with an identification of the receiving antenna are determined. This determination may be used in the handoff process or in detecting when a remote unit requires a handoff.

Appl. No.:

8/414457

Inventors:

Frederick G. Atkinson - Winfield IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04J 316
H04Q 730

US Classification:

370 80

Abstract:

A method (300) and apparatus (200) provide for determining when a digital packet data signal and a voice signal are being concomitantly transmitted on a voice channel of a communication system. A sample of the transmitted signal (110) is compared (310) to a pre-transmitted sample of the digital packet data signal (108). In response to the comparison, a digital packet data transceiver hops (314-320) from the first voice channel to a different voice channel for transmitting the digital packet data signal when voice signals are present.

Appl. No.:

7/277724

International Classification:

H04J 306

US Classification:

370324

Abstract:

In a communications system having transmissions containing certain information-of-interest at predetermined intervals in the transmission, there is provided a method for isolating and processing that information-of-interest. The method comprises sensing the start of a transmission and isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time from the sensed start of transmission. Thus, the information-of-interest is isolated principally on the basis of elapsed time. The method for isolating and processing that information-of-interest is further characterized by sensing the start of a transmission from the received signal power of the transmission exceeding a predetermined threshold; AGCing the transmission and attenuating the AGC'd transmission from a maximum level to a desired level before the information-of-interest is expected to arrive; isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time from the sensed start of transmission, by timing the expected interval between the instant that the start of the transmission is sensed and the predetermined instant that the information-in-interest should arrive (whereby the information-of-interest is isolated principally on the basis of elapsed time); tagging the information isolated about that instant for processing; and beginning processing with information just preceeding the isolated information (whereby the reliability of the information detection is enhanced by one-to-several bits).
