ADDAX IMS Communications. General Description

Normative references ADDAX IMS communications support the requirements of the following international standards

ADDAX IMS Communications. General Description Overview ADDAX Metering Solution provides meter reading, data collection, processing and analysis functions. To implement all of these functions various communication technologies and protocols are used. The purpose of this manual is to give the user an overview of the communication technologies used in ADDAX IMS solutions. An AMI system refers to a combination of metering, communication, information, and control devices, able to monitor, manage, and optimize the interaction between the utility companies and the consumers. It aims at improving the...

ADDAX IMS Communications. General Description 1. General Concepts of ADDAX IMS Solution In order to deal with the bidirectional flow of power and data over the network, providing reliability, availability, security, scalability, and a cost-effective communication infrastructure, ADDAX IMS grounds on the following principles: Standard protocols ADDAX IMS is an open standard-based solution which provides interoperability and interconnectivity with measuring devices and compatible components (hardware/software) of the AMR/AMM/AMI systems produced by other manufacturers. Flexible solution The metering...

2. PL Communications PLC - Power Line Communication is a generic term defining all possible technologies that use the power networks as communication media. PLC technology can be roughly divided into two types - narrowband PLC and broadband PLC. Narrowband PLC works at lower frequencies (3-500 kHz), lower data rates (up to 100s of kbps), and has longer range (up to several kilometres). Narrowband PLC is generally used for home automation, smart metering, or as a component of the Smart Grid. Broadband PLC works at higher frequencies (1.8-250 MHz), high data rates (up to 100s of Mbps) and it is...

ADDAX IMS Communications. General Description • Electromagnetic interference (EMI) may occur, due to unshielded power lines. To improve PLC operation in harsh grid conditions, to maintain signal integrity, and maintain reliable data transmission, technologies and equipment are required. In the following PLC technologies implemented within ADDAX IMS are presented. ADDAX solution aspects: Power Line communication over low voltage network is the main type of communications used between ADDAX meters and data collection equipment. It uses existing Low Voltage Power Lines (0,4 kV), thus providing a...

ADDAX IMS Communications. General Description sum make from the network a complex environment, requiring efficient and reliable solutions to overcome the variety of conditions. In some cases, none of the communication technologies can consistently realize high performance on their own. This way hybrid solution was introduced, as it combines the capabilities of mostly used communication technologies - RF and PLC, enabling to improve the coverage and connectivity, at a reasonable cost. The G3-PLC Hybrid is the first industry hybrid standard offering extended capabilities for smart metering applications...

ADDAX IMS Communications. General Description reasons, initial implementation costs for RF mesh networks may be higher than they are for cellular networks, even if operational costs are lower. To overcome the above-mentioned limitations a number of amendments to extend the original 802.15.4 standard where introduced. The IEEE 802.15.4g amendment defines three new physical layers enabling to extend the communication range and increase the reliability. It operates at sub-GHz frequencies, where the wireless signal can propagate at longer distances, with the same transmission power, introducing additional...

ADDAX IMS Communications. General Description Figure 6. ADDAX hybrid protocol stack The lower layers are based on G3-PLC specification. The G3-PLC data link layer is adapted for hybrid network. The physical layer for PLC supports CENELEC A and FCC frequency bands. The band to be used as well as tone mask can be configured as required. The physical layer for RF supports a large set of bands – from 430 to 1000 MHz. This covers all popular license-free bands for worldwide markets: 433 MHz, 868 MHz and 915 MHz. The main goal of the 6LoWPAN adaptation layer is to optimize the transmission of IPv6...
