 FROM CONCEPT TO COMMERCIAL REALITY  
 
  • Newtec demonstrated the first satellite interactive terminal based on DVB-RCS in the year 1998 at IBC in Amsterdam.
  • Newtec participated in the DVB-RCS standardization process at various stages in the DVB Committee.
  • Subsequently, Newtec decided to develop DVB-RCS based end-to-end network system called “2 Way-Sat”.
  • The first DVB-RCS network was set up in the year 2002 in Europe to support 3,500 SITs which will increase to 20,000 by year 2003.
  • Newtec is setting up a Network in Hongkong (Asia) for an ISP to provide 6000 Satellite Interactive Terminals (SITS).
  • Newtec now provides commercially proven technology for 2 Way-Sat worldwide.

    2 Mbits/s
  • Scalebility :
  • 2 Way-Sat solutions ranging from 100 to 1,00,000 SITs 2 Way-Sat Light – 2 Way-Sat Plus
  • Different Service Levels and Bandwidth Profiles based on Quality of Service concept
 2 Way-Sat APPLICATIONS
DVB-RCS HUB & SIT INTERACTION
 
  • ISP access Networks
  • Wholesale Internet Access
  • Virtual Private Networks for Corporate Companies
  • Multicast E-learning and E-medicine applications
  • Interactive education, Video conferencing
     
 
       
 
 DVB-RCS: Open standard technology and its benefits  
 
  • DVB-group :
    Digital Video Broadcast
    Newtec actively involved in the standardisation of DVB-RCS       (Return Channel via Satellite) EN 301 790
    DVB-RCS Interoperability Group (ESA): ensuring the Open       Standard
    Open Standard = Cost Effective equipment for high volume       markets
  • These standards have been accepted by European Telecommunications
    Standards Institute (ETSI), which has paved the way for interactive broadband multimedia applications for 2 way communication over satellite.
  • It is a recognized fact that privately owned developments (proprietary standards) have limited market potential and these will remain high priced alternatives.
  • DVB-RCS will be of global standards and will attract various manufacturers active in the satellite communication industry, there by bringing in competition and cost-reduction.

INTEROPERATIBILITY WITH SATLABS
 
       
 
 INTER OPERABILITY WITH SATLABS
2 WAY-SAT VALIDATION PLATFORM
 

2 Way-Sat is fully compliant with the DVB-RCS standards. SATLABS have been set up to assure interoperability of DVB-RCS standards and it has been set up by various satellite companies involved in DVB-RCS standardization, namely Eutel Sat, ESA (European Space Agency) and SES (Societe Europeenne des Satellites)

 2 Way-Sat VALIDATION PLATFORM
 
  • Newtec makes continuous efforts to achieve further improvements in its
    2 Way-Sat system performance.
  • Newtec has therefore set up a validation platform which is an identical copy of an operational 2 Way-Sat HUB station along with SITs. This is a 'Satellite-Simulator' which is present in the validation platform with the exception of satellite link.
    This provides confidence during development, production and enhancement of features for 2 Way-Sat customers, but they can also verify DVB-RCS standards on this
 
       
 
 SCALABLE TO YOUR NEEDS :

2 WAY-SAT SCALABILITY
 

One of the unique features of 2 Way-Sat systems is its scalebility which makes the growth possible as and when required. These are the following systems available from Newtec.

  • 2 Way-Sat light: Fully redundant complaint and capable of handling an IP Broadband Access Network upto a maximum of 1000 SITS.
  • 2 Way-Sat plus: Has the capability for enhancement from 4000 to 100,000 SITS, with all the above features as listed in 2 way-sat light.
  • 2 Way-Sat consumer: Is designed to support upto 0.1 to 2.0 million SITS. Ideally such systems would be possible in future with more than 100 transponders for satellite with multiple spot beams in Ku-band.
 
       
 
 LAST MILE TECHNOLOGY - A BOTTLENECK  
 

The illustration shows last mile technology for various applications.The last mile technology still remains a bottleneck for today's Broadband Networks and end customers. Satellite based systems and more particularly DVB-RCS is the best option for urban, semi-urban, residential, rural and remote areas. DVB-RCS technology and more particularly 2 Way-Sat has tremendous potential for providing the benefits to the remote areas of India. In addition to this, it is the best technology for "Interactive education and telemedicine applications".


LAST MILE TECHNOLOGY
 
       
 
 NEWTEC’S SATELLITE INTERACTIVE TERMINALS (SIT)  
 

The SIT is the “User Terminal” which consists of an “Outdoor Unit” (ODU) with a typical 75 or 90 cm Satellite Dish fitted with a combined “Transceiver” unit.
Newtec is able to deliver various combinations supporting transmit and receive schemes in Ku-,Ka- or C-band to provide reliable services in all regions of the world.
The “Indoor Unit”(IDU) consists of a typical PC-size unit to be connected to the user-PC or LAN-server.
The SIT supports incoming transport streams up to 110Mbit/s (4-8Mbit/s IP traffic per SIT), while it transmits data at 2Mbit/s (for example in a 2 Watt SSPA configuration on Ku-Band transponder).
All communications are based on the IP protocol, providing a transparent environment, which supports standard Internet protocols.
Optionallly, value added IP protocol services can be provided such as TCP acceleration, web caching, E-mail services and enhanced security by means of the industry standard IP-SEC and its associated key distribution mechanism.
