Cooters - Nothing says Telson. The main chip has the following markings: MAD4 C V10 4370625 02A63NW Two other similar chips are: CAFE D 437L178 PA9DJ9938 TAIWAN and SEC KOREA 943 KMG8U2000LTGI-IDL From the date codes of the last two chips (943 and 9938, 43rd and 38th weeks of 1999), this phone either was not manufactured recently or they're working off a good sized chip inventory. The last chip is made by Samsung and is a standard part of some kind (memory?), not an ASIC. Regards, Don

Did you note the patent numbers relating to QCOM? From some other site, the patent numbers were given. One seems to be in error, I checked them on the US patent office site, yes, it is a slow night. Patents are good for 17 years or has it changed? 17 years gives 2006, 2008 and 2009 or so as the end. ------- From MF -- Opening the back of the 5185i AGAIN :-( Licensed by Qualcomm Inc under one or more of the following patents 4,901,307 5,109,390 6,266,119 5,267,261 MADE IN KOREA --------- The third patent number seems to be incorrect. The abstract for the other three are below. United States Patent 4,901,307 Gilhousen , et al. February 13, 1990 -------------------------------------------------------------------------------- Spread spectrum multiple access communication system using satellite or terrestrial repeaters Abstract A multiple access, spread spectrum communication system and method for providing high capacity communications to, from, or between a plurality of system users, using code-division-spread-spectrum communication signals. The communication system uses means for providing marginal isolation between user communication signals. The marginal isolation is provided by generating simultaneous multiple steerable beams; using an omni-directional antenna with polarization enhancement; using power control devices to adjust the output power for user generated communication signals either in response to their input activity level, or in accordance with a minimum allowable power for maintaining a communication link. The communication system can also employ a means for transmitting a predetermined pilot chip sequence contiguous with the code-division-spread-spectrum communication signals. In further embodiments the communication system employs a plurality of user terminals linked to each other or to other services through one or more terrestrial or satellite repeaters. Multiple satellite repeaters are operable in a new communication mode to obtain further gains in signal isolation. United States Patent 5,109,390 Gilhousen , et al. April 28, 1992 -------------------------------------------------------------------------------- Diversity receiver in a CDMA cellular telephone system Abstract A spread spectrum receiver subsystem for utilization in a CDMA cellular telephone having a searcher receiver for scanning the time domain so as to use the PN processing gain and time discrimination properties of spread spectrum coding to determine the location in the time domain and the received signal strength of multiple receptions of a pilot signal traveling upon one or more physical propagation paths to reception. The searcher receiver provides a control signal indicative of the received pilot signals of greatest strength and corresponding time relationship. A data receiver receives spread spectrum communication signals accompanying each received pilot signal and is responsive to the searcher control signal for acquiring and demodulating a spread spectrum communication signal, concomitant with the pilot signal of greatest signal strength, and thus providing a corresponding information bearing encoded output signal. United States Patent 5,267,261 Blakeney, II , et al. November 30, 1993 -------------------------------------------------------------------------------- Mobile station assisted soft handoff in a CDMA cellular communications system Abstract In a code division multiple access (CDMA) spread spectrum cellular communication system in which a mobile station user communicates with another system user via at least one base station, wherein each base station transmits a common pilot signal of a different code phase with respect to other base stations in said system, a method for directing communications between said mobile station user and said base stations. The mobile station monitors the signal strength of pilots and reports the measured signal strength to a system controller via the base station through which it is communicating. Command messages from the system controller to a new base station and the mobiles station establishes communication through the new base station in addition to the communication through the current base station. When the mobile station detects the falling below a predetermined level of the signal strength of a pilot corresponding to at least one of the base stations through which the mobile station is communicating, the mobile station reports the measured signal strength indicative of the corresponding base station to the system controller via the base stations through which it is communicating. Command messages from the system controller to the identified base station and the mobiles station terminates communication through the corresponding base station while communications through the other base station or base stations continue. --------------------------------------------------------------------------------
