INTRODUCTION The WIT608B radio transceiver provides reliable wireless connectivity for either point-to-point or multipoint applications. Frequency hopping spread spectrum technology ensures maximum resistance to noise and multipath fading and robustness in the presence of interfering signals, while operation in the 611 MHz WMTS band allows protected operation in the US. A simple serial interface supports asynchronous data up to 115200 bps. An on-board 3 KB buffer and an error-correcting over-the-air protocol provide smooth data flow and simplify the task of integration with existing applications. Radio Features include: - Multipath fading impervious frequency hopping technology with 39 frequency channels (608-614 MHz). - Supports point-to-point or multipoint applications. - Meets Part 95 FCC rules - Superior range to 802.11 wireless LAN devices. - Transparent ARQ protocol w/3KB buffer ensures data integrity. - Low power 3.0v CMOS control signals - Simple serial interface handles both data and control at up to 115200 bps. - Fast acquisition typically locks to hopping pattern in 4 seconds or less. - ~10 mW transmit power. - Support for diversity antenna. - Built-in data scrambling reduces possibility of eavesdropping. - Nonvolatile memory stores configuration when powered off. - Smart power management features for low current consumption. - Dynamic TDMA slot assignment that maximizes throughput. 2. RADIO OPERATION 2.1. Synchronization and Registration As discussed above, frequency hopping radios periodically change the frequency at which they transmit. In order for the other radios in the network to receive the transmission, they must be listening to the frequency over which the current transmission Murata Electronics 2021 is being sent. To do this, all the radios in the net must be synchronized and must be set to the same hopping pattern. In point-to-point or point-to-multipoint arrangements, one radio module is designated as the base station. All other radios are designated remotes. One of the responsibilities of the base station is to transmit a synchronization signal to the remotes to allow them to synchronize with the base station. Since the remotes know the hopping pattern, once they are synchronized with the base station, they know which frequency to hop to and when. Every time the base station hops to a different frequency, it immediately transmits a synchronizing signal. When a remote is powered on, it rapidly scans the frequency band for the synchronizing signal. Since the base station is transmitting over 39 frequencies and the remote is scanning 39 frequencies, it can take several seconds for a remote to synch up with the base station. Once a remote has synchronized with the base station, it must request registration from the base station. The registration process identifies to the base station the remotes from which transmissions will be received and not discarded. Registration also allows tracking of remotes entering and leaving the network. The base station builds a table of serial numbers of registered remotes. To improve efficiency, the 24-bit remote serial number is assigned a 6-bit “handle” number. Two of these are reserved for system use, thus each base station can register 62 separate remotes. This handle is how user applications will know the remotes. Note that if a remote leaves the coverage area and then re-enters, it may be assigned a different handle. To detect if a remote has gone offline or out of range, the registration must be “renewed” once every 256 hops. Registration is completely automatic and requires no user application intervention. When the remote is registered, it will receive several network parameters from the base. This allows the base to automatically update these network parameters in the remotes over the air. Once a parameter has been changed in the base, it is automatically changed …

March 15, 2021 TCB Applications Examiner RE: Modular Approval for Murata Electronics North America FCC ID: HSW-608B Dear Applications Examiner: Regarding Part 2 Subpart J, Equipment Authorization Procedures: 1) The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The Murata Electronics North America model WIT608B is a completely self-contained radio which has its own RF shielding on the RF section. No other RF shielding is required or implemented. 2) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or overmodulation. The Murata Electronics North America model WIT608B controls the data flow to the transmitter section compliant with Part 95H requirements. 3) The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. The module does have its own power regulator circuit and will not depend on the host device to provide it with the necessary and correct voltage for operation. The Manufacturer will ensure that the proper instructions are provided to the integrator. 4) The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). Any antenna used with the module must be approved with the module, either at the time of initial authorization or through a Class II permissive change. The “professional installation” provision of Section 15.203 may not be applied to modules. For this application the Murata Electronics North America model WIT608B employs antennas with unique connector (MMCX). The radio has been approved for use with a +2 dBi Patch antenna or +2 dBi Dipole antenna. 5) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)). The module was tested standalone. An interface board was provided as a means to communicate with the radio through the serial connection. Nothing on the interface board contributes to the performance of the radio, therefore the radio is considered to have been tested in a standalone configuration. 6) The modular transmitter must 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. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. The Murata Electronics North America model WIT608B shall bear a label with the FCC ID on the front of the module. The FCC ID shall be visible when installed on the host device. The Host device will bear a label calling out the FCC ID using a statement similar to the following: “Contains FCC ID: HSW-608B”. 7) The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. The Murata Electronics North America model WIT608B comes equipped with embedded firmware that controls these parameters. 8) The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform …
