VSAT - Implementation & Maintenance

NWNS traditional core business.

SD-WAN - Implementation & Maintenance

SD-WAN reduces cost through WAN flexibility and simplifies operations with centralised provisioning, management, policy control and application visibility. Multiple layers of security protect against Internet and branch cyber threats.

Compute and storage, as well as core applications like CRM, HR and Microsoft Office, have moved to the cloud. Yet WANs continue to use 20-year-old private line technology (MPLS) and expensive, proprietary networking hardware. This results in slow provisioning times for new offices or even basic changes to configurations and functions, high costs for network equipment and WAN services, complex branch architectures and high administrative overhead.

NWNS supports global communication service providers offering software-defined WAN (SD-WAN) managed services to serve global multinational corporations.

Since its inception in 2015, SD-WAN has been intended to provide a cost-effective solution for handling increased traffic demand at the edge. This however is more complicated than expected because the devil is in the detail. 

Communication service providers must establish partnerships with last-mile providers to expand their global
footprint. From feedback and experience, NWNS understands the challenges related to deployment, configuration and integration of SD-WAN into legacy and operational networks. 

NWNS can help service providers sourcing local partnerships or be the partner to implement software-defined and fully virtualised network architecture. 

In return customers will experience the joy of accrued benefits related to cost-effective increase in bandwidth, higher availability, and improved connectivity to cloud applications.

5G Holds Promise as an Attractive SD-WAN Transport Option

We've started seeing initial pockets of 5G deployment. To date, 4G access has primarily been used as a backup to higher bandwidth broadband internet connectivity because of its relatively low capacity and high cost per bit. 5G wireless access promises higher throughput rates and, if priced appropriately, will become an attractive addition to the portfolio of SD-WAN transport options which today include broadband, DIA and MPLS. 

5G could deliver a unique combination of fast deployment, diverse connectivity and high bandwidth that accelerates the adoption of broadband SD-WANs. 

NWNS can help you sourcing your best matching solution and finding the right ways to implement this fascinating next phase of communications technology development.

Radio Spectrum Interference & Radiation Analysis

One issue that is of daily concern is spectrum interference, and this issue is an increasing challenge as new technologies allow the greater exploitation of the spectrum environment. Each comms system will have its own individual demands for spectrum that are required to be met and of course, it is critical to ensure that these communications are protected from harmful interference.

Studies undertaken have shown that there are maybe several thousand widely differing potential sources if interference within the range of a wireless receiver including WiFi, satellite antennas, microwave stations etc.

Interference can get into the receiver "through the air", down the power supply line, over the casing or through other "loopholes", and cause problems, serious trouble or total outage. An invisible problem one not always thinks about. 

Awareness is 50% of the solution.

NWNS Can Help You Tracing Interference

NWNS is geared-up and has the knowledge to professionally help you in the localisation of interference and finding the appropriate solution to mitigate the problem (if possible). Not through "trial and error" but through serious measurement using serious equipment, models and calculation. To read more about interference and our solutions please click here.

(Off-Grid) Power Solutions - Supply, Implementation & Maintenance


Power-Grounding-Lightning Protection Site Survey

VSAT equipment together with most other communications and computer equipment is very sensitive to unstable power supply, improper grid design and out of specs implementation. Power related problems that may have a direct negative effect on the performance of such equipment could be: 

  • Blackout: Complete loss of power - very typical problem for many people and businesses;
  • Sag or Brownout: Decrease in voltage levels which can last for periods ranging from fractions of a second to hours. Sag can be caused by heavy equipment coming on line such as tools, elevators, compressors etc. It also frequently occurs when utility companies deliberately do this to cope with peak load times.
  • Spike: This is a tremendous increase in voltage over a very short period of time often caused by a direct lightning strike on a power line or when power returns after a blackout.
  • Surge: This is a substantial increase in voltage lasting a small fraction of a second, often caused when high powered appliances such as air conditioners are switched off.
  • EMI/RFI Noise: Electro Magnetic Interference and Radio Frequency Interference. Caused by lack of electrical earthing, lightning, generators, radio transmitters, industrial equipment etc.

Some or all of the above listed incidents or situations are likely to be expected at certain Customer facilities around the world. The negative impact can be mitigated or controlled through better understanding and recognising the problem and appropriate follow up action. 

NWNS can help analysing the local situation and help its customer to better understand the power quality problems they may have and how to fix or mitigate them. The ultimate goal of a NWNS Power Site Survey is to reduce down time and saving money on equipment replacement.

Like all electrical and/or electronic equipment troubleshooting, site surveys rely on state-of-the-art diagnostic test equipment and the intuitive nature of the person using this equipment. Although most of us would like to think we are fully capable of doing such work, varying levels of expertise may prevent us from successfully resolving a power quality issue. 

You simply need expertise, applying proper test methods.

NWNS has the expertise and the diagnostic equipment and an organised approach. We ensure an effective investigation, proper data collection, accurate conclusions, and cost-effective recommendations.

How we work:

  • Step 1: Customer submits a request + problem description. We are asking customer to use our low entry on-line questionnaire which is a “walk-through” and our organised way to gather the basic facts necessary to define the problem.
  • Step 2: NWNS reviews the received information and identifies the power quality concern. NWNS will discuss with the Customer what course of action best serves the site's needs.
  • Step 3: NWNS dispatches a skilled certified engineer to conduct a power survey (if desired). He or she will organise and perform the site analysis which include a long list of predefined tests and measurements. Most surveys will fall into one of the following categories: 
    • Level 1 survey: This covers the visual inspection, testing, and analysis of the AC premises wiring and grounding system supplying the affected equipment; 
    • Level 2 survey: This includes a Level 1 survey plus monitoring the applied AC voltage and load current of affected equipment;
    • Level 3 survey: This consists of the Level 1 and 2 surveys plus monitoring environmental site conditions. A detailed look at possible radio frequency interference (RFI), electromagnetic interference (EMI), electrostatic discharge (ESD), and improper levels of temperature/humidity.
  • Step 4: NWNS will produce a professional evaluation report and provide recommendations to cost-effective solutions. The report will also include potential safety hazards, suspected problem areas, and possible solutions.

Our Experience:

Many power quality problems are in a way related to the wiring and grounding system. This is why NWNS does not want to overcomplicate things hence we don’t assume anything. First, we take a step back and take a look if things don’t look right. Then we follow common sense rules.

Improper neutral-ground bonds in branch circuit panel boards, incorrectly installed Isolated Ground (IG) systems, overcrowded branch circuits, and poorly maintained earthing systems are just some of the conditions we frequently identify as trained observer through visual inspection. Not to mention unsafe conditions for personnel ….
