Objectives
The objective of the project is to enhance existing SatLink VSAT network capabilities by further developing functionality related to mobility, security, and bandwidth efficiency by:
- Further developing seamlessly Global roaming and enhancing the QoE for mobile and maritime customers through Global NMS and Mobility Controller.
- Providing the next generation SatLink VSAT and HUB modems.
- Enabling new Security measures in these areas: communications, encryption and equipment.
- Upgrading forward link to S2X and increase throughput.
- Preparing technology platform for future higher data rates.
Challenges
It is important to ensure a seamless and cost efficient upgrade path to DVB-S2X for existing SatLink customers by:
- Supporting networks operating DVB-S2 and DVB-S2X in parallel and successively upgrading remotes.
- Enabling option of HW upgrade of existing remote modems by mounting a DVB-S2X Plug-in receiver or use of a new DVB-S2X compatible remote modem.
System Architecture
The SatLink satellite modem networking system provides broadband IP networking capability for operators that offers end-users broadband IP services by using VSATs and geostationary satellites. A modem network can be utilised by a single operator or it can be used to host virtual network operators (VNO) as desired. Each VNO has limited and restricted access to the management system and may manage a subset of the VSAT Modem Units(VMUs). The network is suited for end-users in fixed locations, on maritime vessels and on land-mobile units. Interconnection with terrestrial WAN infrastructure can be provided e.g. by having the hub hosted in a satellite teleport with good WAN interconnectivity.
The satellite networking topology that is supported is hub-spoke networking for IP traffic, using DVB-S2, DVB-S2X and DVB-RCS2 signals.
Plan
The project duration is 3 years starting Q2 2020, divided into 3 stages where in addition to continuously enhancing and developing new features for mobility, security and bandwidth efficiency, there is development of new DVB-S2X compatible HUB and VSAT modems, main HW developments per stage are:
- Stage 1: New DVB-S2X compatible Hub Transmitter and a DVB-S2x plug in receiver for remotes.
- Stage 2: New DVB-S2X compatible VSAT modems.
- Stage 3: New combined transmitter and receiver for the Hub.
Current Status
First stage of development.
