Network Synchronization and Timing
Digital transmission requires precise bit synchronization. As more complex high-speed communication networks are rolled out, the need for precise synchronization becomes more critical. Telecom operators today have to meet the growing expectation of customers in the form of SLAs, which emphasizes on the transmission reliability and service uptime. The demand for quality transmission therefore leads to a requirement for sophisticated clock and synchronization systems.
We market a full range of synchronization and clocking solutions for all levels of a telecom transmission network – PDH, SDH, SONET, ATM and also cellular telecom networks. The products ranged from Cesium-based or GPS-based Primary Reference Clock to Synchronization Supply Units to Local Retiming Units, all based on the ITU-T and ETSI specifications for synchronization requirements.
The need for synchronization further extends beyond transmission networks. High speed and distributed transactions requires precise time synchronization, not only for the completion of the transaction but for post-event analysis as well. Examples include stock and financial transactions, network security and SCADA data loggers. The de facto standard for timing synchronization in computer networks is the Network Time Protocol (NTP). A standalone GPS-based network timeserver can synchronize every device on the network using this protocol.
We provide total repeater solutions to wireless service operators, offering over-the-air and linked network repeaters, network management software, RF engineering design tools and installation services.
Network repeaters are the most cost-effective solution to enhancing coverage of a wireless network, in traditional usage such as hole filling and in-building coverage. In new network rollouts, especially in suburban, rural and highways, coverage is most often more important than capacity. In such a situation, the Repeater Hybrid Networks, a combination of traditional base stations and repeaters offers the wireless service operator cost savings not only in capital infrastructure costs, but operational costs as well while extending the desired coverage.
The demand for broadband access continues to outgrow the installed base, even when deployment of broadband access is fast growing. All around the world, broadband wireless is being looked at as the technology of choice for fast deployment and reliable service. While older wireless systems are limited by radio line-of-sight, state-of-the-art wireless systems employing adaptive antenna beam-forming and advanced modulation technique allows for non-LOS deployment.
We offer the only zero-install, true non-line-of-sight, nomadic broadband wireless access system available today. The system operates in the 2.4 GHz, 2.6 GHz or 3.5 GHz frequency band and is scaleable to support hundreds of users per base station.
We market wireless rural telephony systems, which helps to bring voice, data, fax and Internet connection to isolated low-density rural areas, that may otherwise lack access to basic modern communication facilities.
Providing a connection to the PSTN via analog or digital radio links, rural telephony system is a cost-effective solution in bringing rural areas into the mainstream communication infrastructure and bridges the rural community with the modern world.
Optical communication is the technology of choice for high speed networks with virtually unlimited distance and bandwidth. Almost every long distance data or voice call made today passes through an optical network. Over the last few years, optical fibers have started to be deployed in private networks. With more and more private networks going all optical, the technology is now entering the MAN and the LAN.
The optical products that we provide ranges from optical converters and modems to fiber optic backup device to state-of-the-art DWDM and CWDM systems.
Lightning protection is a pre-requisite to any successful communication network, be it a cellular network or a computer network. Lightning protection systems protects all infrastructure equipment and installations from being damaged by dangers such as lightning, power surge and volatility and etc.
We provide lightning protection systems for a wide range of industry markets – wireless, satellite, broadcasting, microwave, military, LMR and etc. in applications such as power line protection, grounding solutions, coaxial protection, data/phone line protection and etc.
