Here are the diagrams for typical InFlexion frames 1 frame = 1 division = 1.875 seconds Summary of Protocol-compliant worst case scenarios for the Boomerang Pager Pager Scenario#ACKs/#Frames% of Frames with ACKS Registration attempt15/3444.12 WRU w/ WRU ACK½50.00 Voice msg w/ msg read ACK 3/6 50.00 This document describes the theoretical maximum inbound traffic that can be generated by a Boomerang pager. In most cases, this traffic will be less than the minimum traffic described in ReFLEX InFLEXion Protocol Specification Document Version 2.6 due to software limitations. There are three scenarios described below: 1) Maximum Inbound Traffic Caused by Registration Failures 2) Continuous stream of WRU and WRU Responses 3) Voice Message Transmission These scenarios do not reflect typical system/pager/user behavior although they are theoretically possible. Boomerang has greater limits than the protocol specifies in Section 8.5.4 Minimum Personal Decoding Requirements. The maximum message activity in a Boomerang pager is: 1 address per frame 1 pending vector (vector to ACK) 1 pending message (vector to last fragment) 8 pending fragments Boomerang is also restricted on the number of inbound responses that it can handle (see Section 8.6.6 Minimum Inbound Scheduling Requirements). Boomerang can only support: 1 pending scheduled inbound response, and 1 pending inbound (ALOHA) command Boomerang was designed to handle one transaction at a time pager, and is therefore only able to decode one vector per frame on its personal address. Any additional vectors sent in the same frame will be ignored by the pager (as described in Section 7.4.3 Error handling table). Although the pager can be directed to ACK in the same frame as received address/vector, Boomerang does not have this ability. If the system specifies a rf (response frame) of 0 in a vector, Boomerang will process the vector, but will not generate a response. The ACK will be discarded. Scenario 1: Maximum Inbound Traffic Caused by Registration Failures ------------------------------------------------------------------------------------------------------- The worst case inbound traffic scenario occurs when a pager is not registered on the system. If the system is configured so that the randomization interval is zero (ri = 0), the aloha timeout is zero (t = 0), and the number of retires is 14 (rt = 7), the pager will transmit fifteen registration requests in consecutive frames. After transmitting the 15 ACKs, the pager will move from WAIT to OUT and scan for a new channel. The time required to find the system is dependent on the pagers codeplug configuration. For a worst case scenario, the pager would be programmed with a Frame Scan Timeout of 0 (FST=0). The typical values are usually 4 or 5. A FSTO of 0 causes the pager to sleep for a minimum of 2 frames, channel activity detect for one frame, and SPID match for 1 frame. If the pager finds activity and a matching SPID on the first attempt, it will begin sending in another 15 zone registration requests. This configuration is particularly bad because the system will never be able stop the Registration Requests. In this case, the pager will transmit in one slot in 15 out of 19 frames (about 79% of frames will contain ACKs). If the FSTO of the pager is increased to a typical value, the percentage is greatly reduced. While it is possible for the system to be configured with an aloha timeout of 0, it violates the protocol. The protocol specifies that the aloha timeout must be between 1 and 255 (Section 3.7.6.21 BIW for ALOHA Time-out Period and Randomization Interval). If an aloha timeout of 1 is used, the pager will still ACK 15 times, but will wait one frame between each ACK. If the system doesn't respond after the 15th attempt, the pager will sleep for 2 frames, channel activity detect for 1 frame, and SPID match for one frame before restarting the registration requests. This results in ACKs in one slot in 15 out of 34 frames (about 44.11% of frames contain inbound traffic). Scenario 2: Continuous Stream of WRU and WRU Responses -------------------------------------------------------------------------------------------- This case could occur if the system transmits a WRU Vector to a pager in every frame with a response scheduled for the next frame. The pager will receive the vector in the first frame, but miss the WRU vector in the second frame because it is transmitting a scheduled response. This will cause the pager to ACK in every other frame (50% of frames contain inbound traffic). Boomerang is limited to one pending vector (vector to ACK), so multiple responses can not be queued up by the system. Scenario 3: Voice Message Transmission -------------------------------------------------------------- The third scenario is only possible if the system has zero turn around time for message scheduling. This means that the system needs to receive a response in one frame and act on it in time to transmit additional information in the very next frame. It is highly unlikely that any system will ever be this efficient. However, assuming an ideal system, the pager could generate the following traffic: a) WRU vector from system b) WRU response from pager (ACK) c) WTL vector from system with 1 fragment scheduled and 1 response d) Voice Fragment for WTL vector e) WTL response from pager (ACK) f) Message Read response from pager (ACK) This results in 3 inbound responses for every 6 frames (50% of frames contain inbound traffic). It is also unlikely that the user would be able to generate a Message Read response that quickly, but these are all worst case assumptions. ------------------------------------------------------------------------------ For Reference purposes: From ReFLEX InFLEXion Protocol Specification Document Version 2.6 Section 8.5.4 Minimum Personal Message Decoding Requirements A subscriber unit must support a minimum amount of messaging activity on its personal address. At any time, a subscriber uni…

To: Dr. Kwok ChanDate: 12/28/98 From: Glenn Thompson Subject: Motorola voice pager E9698108, EAS#91635 Dr. Chan, the following information should address your concerns with the Motorola voice pager. The first concern is with the frequency range of the pager. The tunable range listed on the form 731 form is correct. The Rx operates in the 929-932 and 935-941 MHz range (929 to 942 MHz on the 731 Form), under part 24 the TX range is 901-902 MHz and under part 90, 896-901 MHz for operation in the SMR bands. In the future Motorola will test devices which qualify for source-based time-averaging at the maximum duty factors instead of using CW equivalent test signals. However, since SAR-measuring equipment is a low-pass filtering device, in conditions of very low duty-factors the source-based time-averaged measurements might be difficult to perform and the only correct approach is to use CW equivalent signals. Issues 3 through 7 are addressed by the enclosed documents from the Motorola EMI lab in Florida. [see Photos.pdf, Body_Scan.pdf, Holster_Scan.pdf, and manual.pdf] Regards, Glenn Thompson

Thompson Glenn-EGT005 From:Tod Hufferd-ETH003 [[email protected]] Sent:Monday, January 04, 1999 3:31 PM To:Glenn Thompson-EGT005 Cc:Tod Hufferd-ETH003; Ed Clements-FEC004; Michael Piper-WLMP00 Subject:LS950V The LS950V supports one transmission per frame. This consists of a single packet transmission that have varying transmission durations depending on inbound speed. The following are the transmission durations for each of the supported inbound speeds: Inbound Data Rate Transmission Duration 800 bps160.0000 msec 1600 bps 80.0000 msec 6400 bps 24.0625 msec 9600 bps 16.0417 msec The LS950V supports two kinds of inbound transmissions. The scheduled transmission that is controlled by an address/vector combination and the ALOHA transmission that is generated by the subscriber device. To determine the inbound transmission duty cycle both the scheduled and ALOHA transmission will be considered separately. Scheduled Transmissions: The LS950V supports one transaction at a time. A transaction is defined as an address/vector/response combination. The LS950V can receive one address/vector pair in a single frame that can direct the unit to respond in the following frame. Therefore, for a schedule transmission, the LS950V can transmit every other frame. This yields the following transmit duty cycle for a given speed. Inbound Data Rate Transmission Duty Cycle 800 bps .160/3.5 = 4.57% 1600 bps .080/3.5 = 2.29% 6400 bps .024/3.5 = .69 % 9600 bps .016/3.5 = .46 % ALOHA Transmissions: The LS950V supports one active ALOHA transmission at a time. Once an ALOHA transmission has been sent by a subscriber unit, the subscriber unit must wait the ALOHA timeout before sending the ALOHA transmission again. The ALOHA timeout is configurable by the paging infrastructure. The minimum value allowed by the ReFLEX25 protocol for the ALOHA timeout parameter is 1 frame. Therefore, the subscriber device could send an ALOHA transmission in one frame, wait one frame for the response, and retry the ALOHA transmission in the following frame if no response was sent by the infrastructure. The shortest time between ALOHA transmissions would be every other frame. See the table above for the corresponding transmit duty cycle.
