- Clean Channel TechnologyTM, improving efficiency by up to 15%
Future-proof solutions:
- easy upgrade from ASI to GbE, from IF-band to L-band
- DVB-S2 extensions and RF Carrier ID - capabilities are anticipated to become available
The importance of standards is not to be underestimated, they protect end-users from vendor lock-in and provide freedom of choice, which was the aim of the DVB-S (Digital Video Broadcast - Satellite) standard.
At Newtec we strive to increase the efficiency of the DVB standard. That is why we are contributing to a more efficient DVB-S2 standard, to establish an evolution that further optimizes satellite capacity usage.
This presentation focuses on two specific aspects of this strive for improvement:
- How to reduce costs for transmissions (focusing in this case on Clean Channel Technology)
- Addressing Satellite Interference (RFI)

The document discusses digital terrestrial television broadcasting standards and deployments globally. It focuses on comparing DVB-T2's T2-Lite profile to DAB/DAB+ for digital radio broadcasting, showing that T2-Lite enables higher capacity, stronger signals, and larger coverage areas compared to DAB+ using the same or lower transmission power. Specific case studies of DVB-T2 deployments in Copenhagen and potential deployments in Thailand and India are also reviewed.
This presentation, delivered at Submarine Networks World Singapore 2015 (9-10 September 2015 – Singapore), reviews the recent developments in unrepeatered technologies (the 600 km barrier at 100G is now overcome!) and exposes how advanced single-span transmission technologies can be applied to several applications, including terrestrial backhaul and DCI networks at 100G and 400G channel rates.
This document discusses using VSAT satellite networks for oil and gas operations. It highlights how VSAT networks provide reliable communications that are independent of terrestrial networks and can reach remote offshore and inland areas. The document introduces DVB-RCS as an open standard VSAT technology and notes how it supports high-speed forward links, scalability, and quality of service. Finally, it provides examples of how VSAT is enabling real-time monitoring, geosteering, and seismic exploration applications for oil and gas companies.
Cascaded ROADM Tolerance of mQAM Optical Signals Employing Nyquist ShapingADVA
This document summarizes a study on the cascaded ROADM tolerance of mQAM optical signals employing Nyquist shaping. It found that 50GHz channel spaced systems can pass through over 40 ROADMs with minimal penalty, while 37.5GHz spaced systems incur high penalties after less than 10 ROADMs. To improve the tolerance of narrower spaced systems, the study explored using ROADMs with enhanced filter shapes, which provided around a twofold increase in tolerance, and increasing the DSP tap count for a slight additional benefit. Optimizing additional factors like rolloff, timing recovery, and spectral compensation may further improve the cascaded tolerance of closely spaced mQAM signals.
Beyond Consumer and Ka-Band: The Future of Traditional VSATNewtec

The platform supports various broadcast workflows and use cases including contribution, distribution and news gathering. Newtec aims to offer a future-proof solution that can adapt to new services on a shared infrastructure.
At Sveriges Radio, Stockholm February 6th 2015, Mr. Kenneth Wenzel from Open Channel in Denmark shared the experiences gained, from being the world’s first to deploy and trial digital radio based on the new DVB-T2 profile T2 Lite. The presentation proved the superiority and robustness of T2 Lite for digital radio, instead of DAB+, which is widely regarded as obsolete today.
DVB-T2 provides significant improvements over first generation digital terrestrial television solutions. It offers higher data rates and robustness, allowing for more programs including HDTV using less spectrum. The improved efficiency also reduces costs for broadcasters through lower infrastructure expenditures and operating expenses. DVB-T2 supports important features like emergency alerting, mobile reception, and pay television, while also maintaining competitive costs for consumer equipment.
In areas where there are multiple original networks (Original Network IDs) as Copenhagen, where you can receive DTT signals from both Denmark (red) and Sweden (green), the DVB-T2 device (NorDig IRD) shall first sort/list all services from Denmark (Original Network ID = 0x20D0), before sorting/listing the next original network, here Sweden (Original Network ID = 0x22F1).
Within DVB’s SI code allocation (ETR162), there is normally an un-written code of practise for digital terrestrial networks that the original network id has been allocated by the DVB office to the value of 0x2000 plus the country’s ISO 3166 Country code value.
This is true for all countries, except three countries DTT network:
› Swedish DTT (0x22F1), Hungarian DTT (0x22C7) & Portugal DTT (0x22C8)

Ausgrid is investing more than $1 billion in the Sydney CBD electricity network over five years to 2014. Ausgrid's Sydney CityGrid project involves constructing new substations, replacing and upgrading high-voltage cables and constructing a new tunnel to link into our existing network of CBD cable tunnels. These tunnels connect to form an 8 km ring under Sydney's CBD that interconnects Ausgrid's substations.
To provide a GRN P-25 coverage solution into these tunnels for Ausgrid's maintenance staff presented a challenge. Coverage is provided by utilising 'radio over fibre' repeater technology which rebroadcasts the NSW Government Radio Network from two dedicated base station sites located in two of Ausgrid's substations. Radiating cable, fixed to the ceiling of the tunnel, distributes the radio signals to the user in the tunnel, providing a method of communications deep underneath Sydney's CBD, where previously there was no way of communicating with the outside world.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

16APSK Outbound 8PSK Inbound and ACM
.- What mean Highest MODCOD Availability ?
Is the % of time which the Outbound will be operating with the highest MODCOD. For this case, the
Outbound will operate under 16APSK FEC 0.8 in 92% of the time.
.- What mean Required MODCOD Availability ?
Is the MODCOD use to guarantee the availability required to the network: 99%. For this case, the
Outbound will operate under 8PSK FEC 0.8333 with bad climate condition, worst case.
.- How long time the Outbound will operate in Highest MODCOD and in Required MODCOD ?
To this case Highest MODCOD: 92% of the time.
To this case Required MODCOD: 99%-92% = 7% of the time.
.- What about the Inbound ?
The analysis is similar but the Highest MODCOD supported is 8PSK FEC 0.833.
.- What about the satellites Power and BW resources use ?
Like 16APSK use less BW but more power resources from the satellite. The systems is designed to do
the balance Power Vs BW between the Outbound and Inbound. The total power and BW used is
balance.
