Remote Play Inc. FCC ID: ST2-CA100 Request for transmitter modular approval Transmitter Module Characteristics Item Requirements EUT 1 Have its own RF shielding This device doesn’t have its own shielding. However, we apply for limited portable module approval and typical hosting configuration/requirements will be provided in its manual (OEM installation guideline). As requested, the emissions from the module installed in typical hosting device were investigated. 2 Have buffered modulation/data inputs (if such inputs are provided), The RF Chip buffers all inputs. 3 Have it own power supply regulation Refer to the schematic: The RF chip has an internal power regulator.- pin 25 gives the DC/DC output which indicates that there is a voltage regulation. 4 Meet the antenna requirements of Section 15.203 Our antenna is permanent. 5 Be tested in a stand-alone configuration, i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing Tested in this way. And module installed in its typical enclosure were tested for limited modular approval. 6 Be labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. Two proposed FCC ID label format are included in the filing. One of the labels is to be placed on the module and the other label is to be placed on the outside of system. Refer to FCC ID label format and location file. 7 The modular transmitter is manufactured so that the user cannot influence the operation of the transmitter that will operate outside of the scope of the regulations. Refer to “User’s Manual” Exhibit This is the case – User need to use our software 8 Address compliance with the Commission's RF exposure limits in Sections 1.1310 and 2.1093. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF exposure compliance in accordance with Section 15.247(b)(4).

But the device was tested as a hybrid system, the test report says "there is no requirement of minimum number of hopping channels associated with this type of hybrid system" . Please provide technical information as how the device is qualified as a hybrid system. See below. RPI Hybrid system utilizes 10 frequencies for hopping. As is stated in 15.247 paragraph (f) such a system is not subject to a minimum number of hopping channels as long as it complies with the following: 1.It shares all designated frequency equally. 2.It complies with the maximum power density in 3 KHz bandwidth, i.e. < 8 dbm 3.It uses digital modulation RPI system complies with all the three requirements above: 1. It equally shares each frequency channel. It spends 8.25 milliseconds in each channel. 2. Its maximum transmission power is less than 7 dBm. This was verified over more than 100 sets that were built during the prototype phase. 3.It used FSK modulation that is qualifies as digital modulation The system is not designed to skip frequencies and there is no active methods to avoid collisions. [Helen Zhao] According to FCC Q&A in knowledge database, for hybrid system, "However, the hopping function must be a true hopping system, as described in Section 15.247(a)(1). The specific requirements in Section 15.247(a)(1) are: 1) A minimum channel separation. 2) Pseudo-random hop sequence. 3) Equal use of each frequency. 4) Receiver matching bandwidth and Synchronization. The test report answered #1, but how about #2-4. You may need to provide detailed operational description to address these requirements. For your quick reference, here I provide you FCC guideline. [RPI] (1) The minimum Channel Separation is 1 MHz (2) The Pseudo Random Sequence is generated during manufacturing using a Shift Register Style PN Generator in which the 24 bit seed is the device ID. We then use 8-bit numbers out of the register and select only number from 1 to 10. If a number repeats, we ignore the number. (3) When transmitting we repeat the PN random sequence, so every channel is equally used. We never omit frequencies and never use non-frequency hopping operation in all times. (4) The receiver is a synthesizer based super-heterodyne receiver with a bandwidth of 230 KHz. The 20 dB bandwidth of the system is about 400 KHz and the 3 dB bandwidth is less than 200 KHz. The synchronization is done as followed. The receiver waits in a single frequency. The transmitter continuously hopping in the same sequence defined by the system ID as described above. When the transmitter transmits in the frequency that the receiver is waiting on, the receiver locks onto the transmitter, and because it knows the sequence and timing the receiver starts hopping together with the transmitter. Pseudorandom Frequency Hopping Sequence Describe how the hopping sequence is generated. Provide an example of the hopping sequence channels, in order to demonstrate that the sequence meets the requirement specified in the definition of a frequency hopping spread spectrum system, found in Section 2.1. [RPI] The explanation how the sequence is generated is shown above. An example of ID number [00000011101010101111000] will be the following: Which means that the first frequency to be transmitted is the 4 th in the ordered sequence, the second is the 3 rd , the third is 1 st and so on. Equal Hopping Frequency Use Describe how each individual EUT meets the requirement that each of its hopping channels is used equally on average (e.g., that each new transmission event begins on the next channel in the hopping sequence after the final channel used in the previous transmission event). [RPI] Because we never omit frequencies and each transmission on every channel is the same (about 8 milliseconds), we use every channel equally. Each new transmission event begins on the following channel and after final channel used in the previous transmission event. System Receiver Input Bandwidth Describe how the associated receiver(s) complies with the requirement that its input bandwidth (either RF or IF) matches the bandwidth of the transmitted signal. [RPI] as explained above the IF receiver bandwidth is fixed at 230 KHz (around 10.7 MHz) and matches the bandwidth of the transmitted signal in all channels with 3 dB bandwidth of just about 200 Khz and 20 dB bandwidth of about 400 Khz System Receiver Hopping Capability 4 3 1 5 6 7 9 2 0 8 3/7/2005 Describe how the associated receiver(s) has the ability to shift frequencies in synchronization with the transmitted signals. [RPI] The receiver uses a synthesizer to tune into the right frequency. It shifts frequencies such that it always tuned to the transmitter’s hopping frequency. ************ Question #2: Confidentiality requests must reference Section 0.459 at a minimum because this section provides the authority for such a request. Referencing Section 0.457 is not mandatory but it is suggested because this section lists what information is normally held confidential in equipment authorization filings.

Once the module is physically connected through the dedicated connector to a “mother board” loaded with Remote Play, Inc. command and control software it allows robust communication, resilient to interference between two such transceivers. Both modules operate as a pair of transmitter/receiver. Once one module initiate its frequency hopping operation the other module will synchronize its predefined frequency hopping sequence with the initiating transceiver. From the moment of synchronization on the two transceivers will hop in unison according to the PN predefined sequence. Power Supply and Ground The transceivers receive their power and ground reference from the mother board. The voltage is 3 volts +/- 10%
