Sat3Play Terminals From NewTec

The Sat3Play Broadband Terminal is a state-of-the-art, high performance equipment package designed to provide high-speed satellite internet access for the consumer, small office and home office markets. Sat3Play allows ISPs or other IP based service providers to address their market with a truly viable business model. The Sat3Play terminal is capable of supporting a full range of IP services, such as VoIP, multicasting and intranet services.

The Sat3Play terminal implements the most efficient technologies such as DVB-S2 modulation in the forward link, rain fade countermeasures in the return link and IP traffic enhancement software such as TCP acceleration, pre-fetching and encryption.

What is Point and Play?

, a patent pending technology from Newtec, is an innovative self-installation system available on Sat3Play satellite broadband access terminals. The system consists of an antenna pointing tool (shipped with every terminal), combined with advanced software embedded in the indoor modem. It allows the installer (be it a professional installer or the end-user) to easily position the antenna correctly by identifying the satellite and providing feedback on both signal quality and lock. It does not require any software to be installed on the end-users' computer.

Inmarsat Earth Stations

The Nera Inmarsat programme was initiated with terminals in 1974 and extended to include Land Earth Stations (LES) in 1978. Equipment for all types of INMARSAT services has been supplied to the major users and telecommunications administrations world-wide. More than twenty years of experience and know how on development, manufacturing, field work and support will be carried on into new projects, systems and products.

Inmarsat-M/B:

This multi-processor based platform is the basis for most new Inmarsat services, and has been updated with the introduction of a new generation of Channel Units. This technology provides the high flexibility and reduced space requirements needed for the expected large MES populations. A total of 15 systems serving 34 Ocean Regions are to date commissioned for operation.

Inmarsat mini-M:

Mini-M was Introduced with Inmarsat-3 satellites launched in 1996 and 1997. The system, implemented on Nera's Inmarsat-M/B system platform, expands the capacity levels and makes a new step in the evolution of Inmarsat services. A total of 18 systems/contracts covering 37 Ocean Regions are delivered/secured.

Inmarsat M4:

The M4 land mobile system was introduced to the market in the first quarter of 1999. The systems have been implemented on Nera's system platform and expands the functionality and makes a new step in the evolution of Inmarsat mini-M series. A total of 15 contracts covering 33 Ocean Regions are secured.

Inmarsat M4 Aero(Swift64):

The M4 Aero system was introduced to the market in the first quarter of 2002. The systems have been implemented on Nera's system platform and expands the functionality and makes a new step in the evolution of Inmarsat mini-M series. Contracts covering 8 Ocean Regions are secured. The system offers HSD connection to aircraft allowing passengers access to the Internet while in the air. The Inmarsat Aero H/H+/I Access Control and Signalling Equipment family provides telephony, facsimile, circuit switched data and packet switched data services to users via digital satellite channels to and from the Mobile Earth Stations and via fixed connections to the different terrestrial networks. The satellite links are provided by the Inmarsat space segment, which provides global coverage, with four different ocean regions constituting the global satellite network. Each LES may cover from one to three ocean regions, dependent on geographical position. The Nera Aero ACSE are SARPS and ICAO approved, who means that the service also are in use for cockpit voice and data communication towards the flight control segment.

Inmarsat Fleet Services:

The Fleet system has been designed to replace the ageing analogue A system, and the F77 system was introduced to the market in the first quarter of 2002, while the F33 and F55 systems will be introduced to the market in the first quarter of 2003. The circuit switched part of the systems have been implemented on Nera's system platform and expands the functionality and makes a new step in the evolution of Inmarsat M/B series. The Fleet systems can also carry packet switched services, enabling "always on" to provide any ship online access to a whole range of applications like the Internet and e-mail. A total of 11 contracts covering 25 Ocean Regions are secured.

Inmarsat Mobile Packet Data Services:

The MPDS system is designed to deliver packet-based data services, and it is designed to support a range of networking protocols and services over several different physical layers. It was introduced to the market in the first quarter of 2002. The system consists of two major components, the Home Land Earth Station which provides the terrestrial interface to PSTN, public Internet or private corporate networks. The Regional Land Earth Station provides mobile identification and access control to the MPDS network. The Nera system solution has been implemented on commercial off the shelf equipment.

Nera Mobility Management System:

The Nera Mobility Management system is designed for Inmarsat M/B based systems, and is available for Nera designed Land Earth Stations. The Inmarsat Mobility Management system provides the users of the enhanced Inmarsat M/B based system automatic search for the mobile users independent of the location of the MES (MES Mobility) and in the case of Mini-M/M4 also for the SIM cards (Personal Mobility). MES Mobility and Personal Mobility allows the MES and the SIM cards to move between ocean regions, while the Mobility Management System will keep track of the actual ocean region location. This information opens for other value added services like Singe Network Access Code calls, Supplementary Services, Voice/Fax mail and Alerting services.

Single Network Access Code:

The current Inmarsat satellite network system consists of four primary satellites covering four ocean regions with some overlapping between the regions. Each ocean region has its own prefix to reach mobile users in the area covered. Using these four country codes, the calling party have to guess where the mobile is located and in the worst case four calls must be made before the mobile is reached. The Nera Mobility Management system is designed to provide users of the Inmarsat system a single prefix independent of the location of the MES/SIM card. The Mobility Management system will locate the position of the terminal and the call will be established in the correct ocean region.

Supplementary Services:

Supplementary services like:
- Call Forwarding (CF),
- Calling Line Identification Presentation/Restriction (CLIP, CLIR),
- Connected Line Identification Presentation/Restriction (COLP/COLR) are available to both fixed users and mobile users. This information is stored on the Mobility Management platform since these parameters typically will be requested by the network elements in the terrestrial network implementing IN functionality.

Voice/Fax Mail:

In the Inmarsat M/B environment fixed to mobile calls may fail due to the fact that the Mobiles are either not reachable or busy. The Mailbox services make it possible to leave voice and fax messages in these situations. As soon as the mobile is "available/reachable" again, the Mailbox system in co-operation with the Nera Mobility management system and the Nera M/B Access Control and Signalling Equipment will alert the Mobile that a message is present in a mailbox.
