The base stations use a third-party call system to communicate and control the call functions. The repeaters extend the rage of the signal of the base stations, thus providing a wider range for handling the user’s calls. These devices ensure user efficiency across different industries, as an RTX solution can be used in various businesses - from general offices and call centers to storage facilities, hospitals, manufacturing, and retail. The backbone of the network depends on the deployment scenario, but a ring or hub topology is usually used. The network has centralized monitoring and maintenance system. A graphical overview of the architecture of the SME VoIP system setup is illustrated below (Fig.1). Depending on the choice of bases (B700/730 or B760), the system can support from 1 to 249 bases in the same network, and up to 1000 registered handsets. Based on PoE interface, each base station is easy to install without additional wires, other than the LAN cable. The system supports the IP DECT repeater, RTX4027, with support up to 5 channels for simultaneous call sessions. Figure 1 SME VoIP system 2.1 Deployment An SME system setup can be deployed as follows: Single cell setup: Telephony network composed of one base station. Multi cell setup: Telephony network composed of more than one base station. Synchronization Level: The air core interface between two base stations. Base stations are connected via Layer 3 and/or VLAN Aware Router depending on the deployment requirements. The Layer 3 router implements the switching function. The base stations can be mounted on walls or lamp poles so that each device is separated from each other by up to 50m indoor and 300m outdoor (if applicable). Radio coverage can be extended using repeaters installed with the same distance to the base stations. Repeaters are range extenders and cannot be used to solve local call capacity issues. In this case additional bases must be used. The base station’s antenna mechanism is based on space diversity feature which improves coverage. The base station uses complete DECT MAC protocol layer and IP media stream audio encoding feature to provide up to 10 simultaneous calls. 2.2 Advantages Implementing a VoIP system provides many advantages such as: 1. Simplicity. Integrating functionalities leads to reduced main…

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2501A92967E-RFC TR-EM-RF022 Page 14 of 215 Version 3.0 FCC §1.1307(b) & §2.1091 - RF EXPOSURE EVALUATION Applicable Standard According to KDB 447498 D04 Interim General RF Exposure Guidance v01, clause 2.1.4 –MPE-Based Exemption: An alternative to the SAR-based exemption is provided in § 1.1307(b)(3)(i)(C), for a much wider frequency range, from 300 kHz to 100 GHz, applicable for separation distances greater or equal to λ/2π, where λ is the free-space operating wavelength in meters. The MPE-based test exemption condition is in terms of ERP, defined as the product of the maximum antenna gain and the delivered maximum time-averaged power. For this case, a RF source is an RF exempt device if its ERP (watts) is no more than a frequency-dependent value, as detailed tabular form in Appendix B. These limits have been derived based on the basic specifications on Maximum Permissible Exposure (MPE) considered for the FCC rules in § 1.1310(e)(1).
