A complete array of digital radio systems, covering the whole microwave spectrum, is included in the Siemens portfolio to satisfy all low to high capacity needs. Solutions are available for rural and urban applications with both SDH and PDH systems.
Carritech can help you supplying complete nodes and spare parts for the following systems:
Siemens SRA Series 3 – Siemens SRA Series 3is a Point to Point Broadband Wireless system adopting an Indoor-Outdoor architecture ranging from 7 to38 GHz bands. Integrated in the wide range of Siemens products, SRA Series 3 interfaces SONET (OC-3), SDH(STM-1) or Fast Ethernet port(2×10/100BaseT) worlds fitting FCC and ETSI recommended microwave channel arrangements.
Siemens SRA Series 4 – Siemens SRA Series 4 is designed to provide capacities from single to multiple 155Mb/s data channels, up to a total transport capability of 622 Mb/s interfacing SONET (OC-3/ OC-12), SDH (STM-1 /2xSTM-1/STM-4) and add/drop up to42xE1 tributary interfaces performing multiplexing, line protection and cross connection.
It operates from 6 up to 38 GHz.
Siemens SRT1C – Siemens High Capacity Digital Radio(HCDR) systems SRT 1C has the main objective of the compatibility with Synchronous Digital Hierarchy (SDH), so reaching the goal of transmitting 1xSTM-1capacity per carrier with the possibility toprovide interchangeable interfaces:1xSTM-1 electrical or 1xSTM-1 optical.
The introduction of a modulation scheme based on the 4D multilevel 64/128 Trellis Coded Modulation (TCM), optimally decoded by a soft quantized Viterbiprocessor, reaches these goals, enabling the system to meet the required net spectrum efficiency and to achieve the best results in terms of BER performances.
1xSTM-1 traffic per carrier is transmitted in the frequency bands with 28/30 MHz channel arrangement (4L/4/5/6LL/6L/7/8/8U/13 GHz) or with 40 MHz channel spacing(4/5/6U/11 GHz).
Siemens SRT1F – SRT 1F is a digital microwave communication system based on the SDH specifications conforming to international communications standards such as ITU-T, ITU-R and ETSI.
The SRT 1F system processes STM-1(155.52 Mbit/s) base band signals in the SDH hierarchy, limiting their bandwidths within a single radio frequency band stipulated by ITU-R based on a multi-level QAM modulation technology (such as 64or 128 QAM depending on radio frequency spacing). This system can support the full range of radio frequency bands recommended by ITU-R (4G, 5G, L6G, U6G, 7G, L8G, 11G,13G) and frequency spacing of28 MHz, 29M Hz, 29.65 MHz and 40 MHz.
Siemens SRAL – Siemens SRAL is a low capacity 4x2Mb/s system that works in the 7Ghz band as well as the 15/18/23 Ghz bands.
Siemens SRAL XD – Siemens SRAL XD microwave radio fits any transmission requirement in mobile, fixed and private networks. SRAL XD supports all the capacities from 2×2 to 32×2 Mbit/s in a wide range of frequencies from 7 to 38 GHz, providing a reliable, easy-to-install and cost- effective access solution.
