Highlights

• Extensive IP network
• Combination of radio modems and microwave links
• Solution for areas with limited infrastructure
• Connection of schools to Internet

Full IP protocol support and its ability to work in the most demanding of climates means the MORSE system can also be used for connecting to the Internet.

JAVELIN — this authentic project developed by RACOM´s partner in Ghana, Arrow Network System makes use of the permanent and reliable, albeit slower, connection to the Internet via the MORSE network and radio modems.

JAVELIN is used primarily for connecting secondary schools in Ghana to the Internet. The heart of the JAVELIN project is a server on which images of www pages are locally stored, an email server and a scanned textbook. The www pages are regularly updated and emails can be received and sent continuously. Generally a school’s whole LAN network with tens of computers is connected to the server.

The uniqueness of JAVELIN helped it to win the 2006 Education Award Laureate, awarded by the Tech Museum Awards foundation in California, USA.

Since the microwave backbone has got enough capacity, our partner Arrow Network System provides also next clients with data transfer services in places with lack of infrastructure.

Highlights

• RAy, 10 GHz
• Prominent ISP in Philippines
• Backhaul link
• Tropical typhoon conditions
• 20 km / 120 cm antennas
• Exceptional selectivity, hitless ACM
• Good distance/speed/availability balance

Microwave link RAy is used by Philcom in Manila as a part of their backbone. Philcom is one of the leading ISPs in the Philippines. Although the distance between the sites is more than 20 km, thanks to RAy’s exceptional sensitivity the data rate is 170 Mbps for 99% of the time. The customer appreciates the hitless ACM feature, when the link can adapt its speed according actual SNR, e.g. during a tropical rain. 10 GHz band seems to be the right choice for tropical climate. It makes a good compromise between distance / speed / availability parameters of the microwave link.

Highlights

• MG102
• Gas distribution
• Polling & Report-by-exception
• IEC104
• Fully redundant centre
• 2 SIM, 2 operators
• Nation wide, 800 remotes

MG102 wireless routers are used for controlling the natural gas distribution network across the entire Czech Republic.

The requirement was for high reliability, so 2 SIM cards using 2 independent operators are used on the majority of sites. Each unit is configured for possible usage of 2 APN’s (Private and Internet). In case of a problem, MG102 automatically switches to the second APN or operator.

The centre is also fully redundant. There are 2 routers, where communication from MG102’s is terminated and 2 central SCADA computers. The connection from SCADA centre to operators is redundant, too. There are dedicated lines to both operators + Internet in case of drop-out. When any device fails, communication is automatically re-directed to functioning equipment or link.

RACOM provides 24/7 maintenance service with guaranteed time to repair 6 hours.

Highlights

• MR160, 160 MHz
• Sea going vessels
• Fishery GPS tracking
• 9 duplex pairs 25 kHz
• Automatic frequency switching
• 50 base stations
• Capacity for thousands of ships

The MORSE system is also used in maritime communication – an excellent example is the VHF Data network allowing communication between ships on the open sea. Telenor Maritime Radiowho operate the network have equipped their base stations along the whole of the Norwegian coast from Oslo to Kirkenes with RACOM devices.

According to the requirements on the volume of transferred data and available coverage theMRouter on ships switches communication between MR160 and MW160 or via Wifi hotspots.

Narrowband radio modems switch between nine narrowband channels depending on their utilisation.

• Capacity for hundreds to thousands of ships
• 50 base stations along the whole of the Norwegian coast (3000 km)
• 160 MHz
  2 x 9 duplex pairs 25 kHz for narrowband,
  1 duplex pair 200 kHz for wideband
• The MORSE network allows data transfer for:
  • GPS tracking
  • E-mails
  • Point of sale terminals
  • Weather forecasts (using broadcasts)
  • Limited browsing of web pages

Highlights

• MR400, 400 MHz, 900 MHz
• Public transport fleet management
• Buses, trams, trolley buses
• Multiple applications simultaneously
• Every GPS position notified every 30 sec
• RANEC
• 700 vehicles, 25 based stations

The MORSE system is utilised by DPMB for data transfer to assist in managing the smooth flow of public transport within the city of Brno (the 2nd largest city in Czech republic).

Dashboard computers receive a whole host of information from the centre such as the vehicle’s current position, whether it is running in line with the timetable, or information about traffic restrictions or diversions in route. Traffic lights at crossroads are also integrated into the system affording city transport vehicles the right of way if they are late according to the timetable.

Thanks to on-line radio communication the supervisor can always make decisions based on the latest available information.

• The MORSE network provides data transfer for:
  • GPS tracking
  • Configuration of voice network in real time
  • Text information supplied to drivers
  • Immediate status according to timetable (ahead/in line/behind)
  • Right of way for public transport vehicles at crossroads
  • Announcements to passengers in vehicles
  • Ticket machines
  • SCADA system for electrical power panels
  • Article – EUROTRANSPORT 6/2007

Highlights

• MR400, 400 MHz
• Gas distribution
• Nation wide – 50 000 km²
• 5 Masters in 5 locations
• IEC101 and IEC104
• Polling & Report-by-exception
• Up to 5 repeaters in chain

Here a RACOM network used for controlling the natural gas distribution network across the whole of Slovakia makes full use of the unique technical features of the MORSE system and RACOM products.

The network contains a total of five communication centres connected via an IP backbone network. Owing to the mountainous terrain in Slovakia the most distant points are connected via five repeaters. Despite this, the average response time of the network is less than 3 seconds.

The network is supervised using network management software RANEC. There are more than 5 RANEC clients running in the centre in Bratislava.

RACOM Slovakia provides 24/7 maintenance service to the customer, using remote management via Internet.
