WaveSwitch
Futureproof Return Link Technology
In order to maintain a real multi-service operation, an efficient bandwidth-on-demand orchestrator is not enough. In fact, it is also required to assign the correct waveform at the right time according to the different applications and the varying requirements. Hence, WaveSwitch on-the-fly waveform and access method switching technology.
However, unlike other VSAT multi-service systems that partition the bandwidth pool into fixed areas, SpaceBridge’s second generation WaveSwitch technology enables real-time, on-the-fly waveform orchestration as it is maximizing the bandwidth efficiency and providing the best user experience.
Moreover, unlike other solutions in the market, SpaceBridge WaveSwitch™ switching mechanism operates automatically and according to smart configurable triggers to allocate each terminal transmission to the relevant waveform on the fly.
Different Waveforms
In addition, the current access technologies encompassing encapsulation/modulation/coding, collectively also known as waveforms, that used by the majority of VSAT market based on SCPC/FDMA, SCPC DAMA, CDMA, TDMA, and MF-TDMA. Moreover, each access technology affects the application’s performance, overheads, spectral efficiency oversubscription capabilities, and the total satellite bandwidth utilization that eventually influence the user experience and consequently affects the operator revenues and churn rate.
WaveSwitch™ on-the-fly waveform and access method switching technology
Additionally, as traffic characteristics change rapidly there is a constant demand for bandwidth changes and new application requirements. Satellite service providers struggle to decide which platform is most suitable to satisfy the varying needs of their customer applications while optimizing bandwidth utilization. Moreover, to address the high complexity of new generation satellite services without degrading service quality, SpaceBridge introduced WaveSwitch™. In addition, this novel service modeling architecture dynamically optimizes waveform assignment to achieve the highest application performance, with minimum satellite bandwidth resources.
Current platforms offering multiple waveforms require the operator to choose which waveform is optimal for a remote site. Manual intervention is normally required and the type of modem purchased for each site must be consistent with the planned operational mode. Due to readily changing customer requirements, the operators find it harder to predict the proper access technology to use.
With WaveSwitch™, no manual intervention is required. The system will dynamically assign from SpaceBridge’ industry-leading RCSX™ selection of waveforms – ASCPC™, MF-TDMA, and SCPC DVBS2 and DVB-S2X access technologies.
WaveSwitch™ will seamlessly optimize the access technology to the varying customer application requirements in real-time. WaveSwitch allows the operator to choose which waveforms the system would transition between for individual terminals. In cases where high bandwidth isn’t even an option for example, but still involves demanding interactive applications, an operator would configure the system to transition the involved terminals between ASCPC™ and MF-TDMA only. Although WaveSwitch™ is extremely robust, configurable, and allows a set of triggers, it also offers intelligent automatic switching by recognizing the relevant applications and switching the waveform according to their requirements based on intelligent triggers. In parallel, WaveSwitch™ technology enables on the- fly reconfiguration of the system frequency plan, so that the bandwidth allocated in real-time between the three waveforms based on a system-wide bandwidth allocation policy
Triggers
Manual Switching
Used for troubleshooting, test, or when it is known the applications that a specific remote site is using. In addition, manual switching between MF-TDMA, ASCPC™ and SCPC at any time via the NMS is available.
Scheduled Events
Configured by setting the waveform switching in a specific moment and time or for regularly scheduled events. In fact, it is mostly used when the transmissions of specific traffic are planned.
Traffic Volume
Configured to automatically change waveforms upon a certain threshold of traffic.
Traffic Variability
Remote sites can switched between the three waveforms RCSX™ Offers (SCPC, ASCPC™ and MF-TDMA) if it detects different traffic variability.
Pre-Configured Session-App Based
Switched according to a pre-configured session which is based on a specific rules and classifications like multicast sessions based on destination IP Address, Video streaming, specified with Type Of Service, among others.
Link Quality
The system verifies the link quality for each of the remotes and determines if any of them is experiencing difficulties with a certain waveform and the modcod used.
