Main Components of the HUB

-

Main Components of the HUB:

  • Network Control Centre (NCC)  interfaces Operator and HUB for billings assuring traffic management, supervision,  protocol handling and bandwidth management.
  • Forward Link Subsystem (FLS) provides the encapsulation of IP transfer of data packets into adequate MPEG frames,or according to the DVB-S MPEG multiplexer and modulat transmitting specification.

  • Return Link Subsystem (RLS) collects the Turbo-coded MF-TDMA bursts transmitted by all the terminals in the network. Each one of RLS receivers can be individually configured to operate at any frequency, bit-rate or coding rate. The modular design of the RLS enables the system to scale from small to very large networks.
  • Reference and Synchronization Subsystem (RSS) delivers the synchronization and timing information in the gateway for synchronization of the entire satellite network.
  • Remotes or SIT units consist of two main transceiver units, the Indoor Unit (IDU) and the Outdoor Unit (ODU).

Characteristics of HUB Network:

  • Up to 150 Mb/s downstream and up to 25 Mb/s upstream
  • Downstream interface is MPEG/DVB-S (Moving Picture Expert Group/DVB-Satellite)
  • Upstream interface is DVB-RCS
  • Optimized for IP (Internet Protocol) and multi-media contenting Remotes or Satellite Interactive Terminals (SIT)
  • Open standard design (DVB-RCS) Broadband & Multimedia
  • Qualified with multiple IP/DVB broadcast platform vendors
  • The System is designed to support up to 80,000 SIT
  •  unitsEvery Remote Terminal is able to support many PC or IPTV in LAN, depending on used bandwidth
  • DVB-S can be upgraded by the most effective and cost less 2nd generation DVB-S2 CCM and 3rd generation DVB-S2 ACM platform, forward and reverse compatible

DVB-RCS Service and Applications:

  • Broadband Service Provider Platforms (SPP) for Urban, Rural, Remote and Mobile Applications of Multimedia IPTV & ISP
  • Enterprises and Private Networks (EPN) Broadcasting and Content Distribution (BCD) of IPTV
  • Satellite News Gathering (SNG)
  • Satellite Emergency and Security Management (SESM)
  • Global Satellite Augmentation System (GSAS)
  • Defense Information Management (DIM)

What Should You Look For In A Satellite Internet Provider Posted on  February 11, 2014, 10:25 pm  By  admin Satellite Internet providers can be categorized based on the download capacity and speed, customer service and the overall customer experience. The following are some of the prolific internet providers used all over the world: Download Speed Satellite Internet service can vary greatly in speed. Some go barely 5Mbps, while others are as fast as 15 Mbps. In fact the same company can even deliver both speeds because some tie speed to the price of your plan. Data Plan The data plan you choose dictates how much data you can download per month. You can get as little as 5GB per month up to 30 GB per month. You should also be on the look out for companies that offer unlimited free data access overnight. Especially if you or another web user in your house is a night owl, this can save you greatly on the cost of your plan. Quality Service Check out the reputation of the co

Anonymous' New Walkie Talkies Use Radio Waves to Access the Internet

Anonymous' New Walkie Talkies Use Radio Waves to Access the Internet The hacktivist group Anonymous is working on a new communication tool to circumvent censorship and set information free, and it’s going low-tech this time. The project is called Airchat, and it will use radio waves instead of wifi, broadband, or phone lines to communicate data and messages between computers. It’s basically pirate radio for ones and zeros. The idea for Airchat was hatched because of the “lessons learned in the Egyptian, Libyan and Syrian revolutions, but also from the experience of Occupy Wall Street and Plaza del Sol,” explains the  project description on Github , posted under “Lulz Labs,” which was  spotted by  International Business Times . With social upheaval in Ukraine and Venezuela and other places around the world, a safe anonymous way for dissidents to organize movements and share information is as relevant as ever. The radio communication works much like a walkie-talkie or CB rad

A new Internet communications system for space has been tested for the second time, paving the way for faster extraterrestrial communication.  (Photo : NASA) An Internet Wi-Fi system for the moon is significantly faster than home connections here on Earth.   The Lunar Laser Communication Demonstration (LLCD) uses lasers to send Internet service around 239,000 miles from the Earth hto our lunar companion. Investigators were able to upload data at top speeds over 19 megabytes per second (Mbps), and download information at 600 Mbps. This would allow users on the lunar surface to copy more than 100 average songs every second.  NASA uses radio waves to carry data to and from satellites, observatories and the International Space Station. As the need to transmit vast quantities of data becomes more common, this method of communication is less able to meet demands.  Photographs and videos can already be transmitted on the test system, and developers are hoping to accommoda
