• Case study

Smooth traffic flow is vital for any city to function efficiently and Prague is no exception; in recent years the amount of traffic using the city’s roads has increased dramatically! It became apparent some level of management system was required. Kapsch TrafficCom Construction & Realization and CAMEA were awarded a project to provide a solution by Prague Technical Maintenance Communication Centre; installed and implemented in 2015.

Partially funded by the EU, this application provides telemetry data and video from seven arterial routes in Prague; visual detection is provided on each route and data to support traffic flow monitoring and route timing calculations. The large amounts of data to be transferred to the control centre meant Microwave radios would be required, using repeaters along each route; strategically placed sensors and cameras add data flow to the overall capacity requirement at each hop.

After exhaustive appraisal, CAMEA chose to use RAy. In order to make best use of existing infrastructure and reduce disruption during implementation, the FOD design, size and low power consumption of RAy units enabled them to be mounted on existing street lights, operating from existing power supplies and batteries. In addition, the high levels of resistance to interference, a trademark quality on all RAy units, allowed the use of smaller antennas, offering further savings.

CAMEA was grateful for the levels of support received from RACOM who provided full path analyses appraisal during the early stages of link design, recommending optimal frequency of microwave based on potential radio issues on each route. They were also delighted by the ease with which links were connected and managed.

Jan Sedláček, Head of CAMEA IT Department comments: “The reliability of the RAy units was a key factor for us. A problem with any MW radio would affect data being sent from further along the communication path and it would be costly and disruptive to gain physical access to any one site. One and a half years into this project, our choice is vindicated. There have been no stability issues since day One of the project.”

• RAy, 11 GHz
• WISP in Beirut
• Extreme Middle East climatic conditions
• Migration from 5 GHz to 11 GHz
• Backhaul & Last mile
• Receiver robustness = smaller antennas
• Exceptional stability

Data Pro Links in Lebanon is an ISP providing wireless backhaul to cable operators, last mile connections to business, portable online solutions and is one of only a few Providers in Lebanon plugged directly into the world internet backbone. With an ever expanding portfolio, the company’s success created an urgent demand to rethink network configurations to meet the burdens of higher demands.

Operating on the 5GHz band, the increased demand had been causing issues with capacity, stability and latency on the links. Thorough research into the various technologies available confirmed microwave was the best solution. Further research and testing then proved RACOM provided the ideal solution providing excellent cost performance ratios.

Hitless ACM and ATPC proved very effective in protecting data speed and throughput. The receiver robustness to unwanted interference also helped improve data speed and guaranteed sensitivity allowed DPL to build longer links with smaller antennas, offering further cost savings.

Since DPL started deploying RAy microwaves they have entered into a strong phase of expansion, are increasing their market share and have achieved larger capacity and lower latency throughout their network, generating higher data speed and throughput to the more distant parts of Lebanon. DPL are also very complimentary about the levels of support they receive from RACOM. This has seldom been required due to the ease of installation and commissioning of links.

During recent discussions, Mr Bassel Nasr Eddine, Head of Telecommunications said, “The cost vs Performance ratio has proved to be outstanding. This, linked to the reliability of the equipment, further confirmed by generous warranty terms, provides conclusive evidence we have made the right choice by choosing to work with RACOM and use RAy microwave units.”

• Global Telco operator
• Corporate last-mile solution
• Hundreds of links
• Exceptional reliability
• Remote diagnostics and monitoring
• => No maintenance cost

RACOM is pleased to announce yet another success story for RAy2, latest microwave point-to-point link. Worldwide telecommunication company selected RAy2 as a standard network solution.

RAy2, the state-of-the-art, full outdoor radio met all the requirements to be listed as the standard license-free solution for the 10, 17 and 24 GHz links of major Telco operator in the Czech Republic. Links are deployed in cooperation with partner companies NHK Solutions and SUPTel — DISK.

To date, hundreds of links have been installed on dozens of sites within the Czech Republic; the network is continuously growing. Commissioning confirms customer’s expectations: RAy2 provides excellent reliability and is also appreciated for its remote diagnostic and monitoring system, allowing an immediate overview of network status.

The customer is one of the world’s largest telecommunication companies providing a wide range of services including voice, messaging, data and fixed broadband. It has some 450 millions mobile and fixed customers across the globe. Company business is split across two geographic regions – Europe, and Africa, Middle East and Asia Pacific (AMAP)

Highlights

• RAy, 10, 17 & 24 GHz
• Infrastructe for Telco operators
• Used in O2 and T-mobile networks
• Corporate last-mile solution
• Backhaul for DSLAM connections
• Approx. 4000 links
• Press release

RAy has been chosen by competitive tender as the standard solution for mobile operator O2 Czech Republic (Telefonica O2 at time of the tender).

Subsequent to O2 restructuring, the network is now owned and operated by CETIN, the largest data provider in the Czech Republic. 99.6% of the Czech population is covered by CETIN’s mix of mobile GSM, UMTS, LTE and CDMA technologies using almost 6.000 base stations, as well as fixed SDH, WDM, Ethernet and IP technologies.

With the 2014 tender valid for 3 years and for more than 700 links, it was essential to select future proofed and reliable Microwave links for 10, 17 and 24 GHz, all required for the project. After demanding testing, RAy was chosen ahead of almost all world-renowned producers who were also being considered for the contract.

The reasons for RAy being selected were summarized by Martin Králík, Director of NHK Solutions, RACOM’s partner for this project:

“The excellent RAy performance in terms of unique sensitivity and resistance to interference, extraordinary reliability and advanced diagnostics were further complemented by additional features in the new RAy including optical and metallic user interfaces, jumbo frame support, an IP-TV optimized modem and broad range of DC power options. These are all features that make for a perfect fit, to meet the extensive demands of a customer of CETIN’s caliber.”

In this application RAy is used for last mile connection to corporates and as a backhaul for forward DSLAM connections. ADSL (VDSL) connectivity is provided from DSLAM to the end users.

Resulting from complete satisfaction with RAy, the contract with RACOM and NHK Solutions was extended by CETIN in 2017 for three years and then indefinitely in 2020.

RAy links in Cetin network are nowadays used by O2, T-mobile and other Tier 1 operators in Czech republic.
