By Andrew Aroh

Moral, Welfare and Recreation [MWR] programs are a key part of Government and Emergency Response Operation. MWR networks are designed to support remotely deployed emergency response personnel, civilian employees, etc.

Satellite communication plays an important role in MWR programs. due to the fact that emergency response personnel may be deployed in areas suffering from manmade or natural disaster with no terrestrial connectivity.

The amount of data, voice and video exchanged in MWR networks. has grown substantially, along with the wide number of support service that are being offered.

Government and emergency response officials continuously seek new technologies to drive down bandwidth requirements and are working for ways to lower satellite bandwidth cost.

These objectives can be achieved through efficient satellite communication technology solution such as;

  • Adaptive code modulation
  • Cross-layer optimization
  • Data casting
  • Global Reach and Fast Deployment:
  • Humanitarian missions into man-made or natural disaster areas, and peace keeping /relief operations take government and emergency response personnel to remote locations where often terrestrial communication infrastructure is unavailable, or has been destroyed.
  • Scalable Multi-Service Hub:
  • Through the Multi-Service Hub both large setup camps small sites and trucks can be connected with a common forward satellite carrier in order to establish access to MWR video, voice or data services[internet, intranet, TV broadcasting entertainment, telecom]
  • The return technology can be SCPC or MF-TDMA [or a combination] depending on the return data, Size of the remote, Configuration of the network [point-to-point, point-to-multipoint]
  • The Multi-Service hub provides reliable 2-way IP connectivity through a versatile and scalable hub as well as cost-effective and low power consumption remote terminals.
  • The network contains management functions for:

Monitoring and control, SLA Management, QoS, Fair user policy.

  • Double Throughput is some Bandwidth:
  • Both the amount of voice, data and video traffic and the number of MWR networks over satellite have increased substantially.
  • The boost in rates needs to be balanced with the lack of satellite capacity over some areas of operation.
  • Dedicated technologies are being used in a large number of MWR networks to achieve maximum throughput independent of the selected satellite.

At the same time important OPEX reductions can be accomplished.

The used technologies include: Adaptive code modulation, Bandwidth cancellation, Clean channel technology, Equalink.

  • Optimal Service Availability over variable conditions;
  • Even in the most hatsh and hostile conditions it is important to have MWR networks over satellite available for crew and emergency response personnel at all times.
  • However, Fading conditions could seriously disturbed the satellite transmission and lead to temporary link losses.
  • Fading conditions could be due to different circumstances;

The choice of satellite [inclined orbit, ku,-ka-and x-band]

Environmental [tain, dust]

Interference [between two adjacent satellites]

  • Therefore with the auto-adaptive technology these fading conditions will no longer interrupt the transmission between the hub and remote sites nor result in the loss of data.
  • Moreover, service priorities [e.g, voice, data, video] and Quality-of service policies can be auto-adapted on-the-fly depending on the bandwidth availability through Cross-Layer Optimization technology.
  • Support of Voice Data and Video
  • Moral Welfare and Recreation services are a combination of:
  • Voice [calling the home front]
  • Data [social media, email, browsing]
  • Video [news, sports, entertainment, TV and broadcast, training movies]
  • Most of these streaming and file-transfer based services have converged towards IP.
  • Through a multi-service platform the different MWR services over IP can be combined either in the hub or the remote into a single carrier for efficient over satellite at optimal service availability.
  • For the broadband experience over satellite moderns and terminals the MWR network implement the most efficient technologies:
  • Adaptive Code Modulation in the forward link
  • Adaptive return technologies
  • Embedded IP traffic enhancement

Software [aka Cross-Layer-Optimization]:

  • Shaping
  • TCP acceleration
  • Pre-fetching
  • Compression
  • Next to an improved end-user experience, considetable cost gains can be achieved:
  • Reduction of Webpage word. Time up to 60%
  • Reduction of file Download up to 90%
  • Up to 35% Bandwidth Reduction
  • Reliable and Efficient Data Casting:
  • Multicasting MWR content towards remote sites and total areas with Data casting software will immediately result in important efficiency and OPEX gains.
  • The transmission towards remotes are aggregated in a common efficient DVB-S2 ACM forward over satellite.
  • The content is stored on the server located at the remote.
  • The reliability of the data casting [digital cinema, news, shows, etc.] is enhanced by the software’s partial retransmission capabilities.

Only the detected missing fragments are retransmitted which provides important OPEX gains for services on- the-move or those suffering from fading or interference conditions.

  • Data casting software also has the following possibilities:
  • Dynamic scheduling & prioritization
  • Authentication, Authorization & Accounting
  • Automated content Distribution via ‘’hot folders’’
  • Monitoring & Control.

5G Subscriptions Hit 2.7m in Nigeria –NCC

Nigeria’s mobile network landscape is seeing a gradual shift towards newer technologies, with 5G subscriptions reaching 2.7 million in March 2024, according to the Nigerian Communications Commission (NCC).

5G Subscriptions Hit 2.7m in Nigeria –NCC

This translates to a 1.24 per cent penetration rate.

While this represents steady growth compared to December 2023 (1.04%), 2G remains the dominant network choice, accounting for over half (56.97%) of all connections. 3G holds a 9.04% share, while 4G subscriptions have grown significantly from 25.06% in May 2023 to 32.74% in March 2024.

The high cost of 5G-compatible smartphones is a major barrier to wider adoption. Although all three major operators – MTN, Airtel, and Mafab Communications – offer 5G services in select cities, expanding coverage and affordability remain key challenges.

MTN launched the first 5G network in September 2022, followed by Airtel in June 2023. Mafab entered the market later in 2023. All three companies are aiming to expand their reach, but the high cost of 5G devices is a significant deterrent for many Nigerians.

According to Mohammed Rufai, chief technical officer, MTN, maintaining older networks (2G and 3G) alongside newer ones is necessary due to device compatibility issues.

This highlights the need for a wider range of affordable 5G-compatible phones to truly unlock the potential of this next-generation technology in Nigeria.

Experts Seek Stricter Regulation against Call Masking, SIM-Boxing Fraud

Published

Experts have called for stronger laws and stricter regulation to tackle security issues around call masking and Subscriber Identity Module (SIM)-boxing-related fraud in Nigeria, according to the Nation.

Experts Seek Stricter Regulation against Call Masking, SIM-Boxing Fraud

Call masking or refilling is a practice in which international calls are terminated in Nigeria as local numbers, using illegal SIM boxes loaded with several numbers.

It is a deliberate attempt by fraudsters to avoid paying the correct International Termination Rate (ITR) for international calls, paying instead the Local Termination Rate (LTR).

For example, when the number is masked as a local call, an operator pays N3.90 LTR and not N24.40 ITR.

The process allows operators to terminate inbound international telecoms traffic as local calls, so they do not have to pay ITR, which is the interconnection charge set by telecoms traffic carriers as carrier-to-carrier charges.

A SIM Box fraud is a setup where fraudsters install SIM boxes with multiple prepaid SIM cards.

A fraudster can bring calls through VOIP (through the internet) and terminate international calls through local phone numbers from a country, to make it appear as a local call, by initiating the call through a local SIM installed in the SIM box.

About three years ago, when the issue came to the limelight, the Nigerian Communications Commission (NCC) carried out some investigations, leading to the sanctioning and suspension of some operators earlier this year.

Some of these suspensions were later lifted.

The Office of the National Security Adviser (ONSA), the National Intelligence Agency (NIA), the Department of State Services (DSS), and Committees of the House of Representatives and Senate have on several occasions expressed concern about the menace.

While many stakeholders believe that the menace has been nipped in the bud, it has continued to rear its ugly head to the bewilderment of experts and stakeholders.

Ikechukwu Nnamani, president/chief executive officer of Medallion Communications Limited, lamented that it is a subject matter, which NCC should address completely.

Nnamani, who is an executive member of the premier telecom body in Nigeria – the Association of Telecommunications Companies of Nigeria (ATCON), said almost all calls he received recently are masked.

“Sometimes, I don’t pick up calls because I do not know the number only to find out later it was an international call.

“The truth is that I don’t know why this has not been resolved, I expected it to have been solved.

“Honestly, I would not know why. One would have expected them to have sorted all these out by now,” he said.

Chief Deolu Ogunbanjo, president of the National Association of Telecommunications Subscribers of Nigeria (NATCOMS) said there was no need to relent in reporting the menace to the right authority.

He said it could be a plan to ensure that gain accrued to some people. “I don’t know whether call masking favours the operator or it is being done deliberately.

“It is a situation that the telecoms should deal with because it is a technical problem. I think it is some of those unlicensed operators doing all these.

“Some of these operators’ facilities are being tapped into; they need to look into their operations, so they can be taken care of.

“If they are still in the habit of doing it, proper sanctions should be meted out to any erring service provider.

“There should be heavier sanctions. They can’t be short-changing subscribers and at the same time, the government,” he said.

Mr. Ajibola Olude, executive secretary of the Association of Telecommunications Companies of Nigeria (ATCON), believes the issue can be addressed.

“When it comes to technology, you can only address it maximally. It is not as rampant as before and it is an international issue.

“We have addressed it before and we will look at it again.

“About four years ago, when it happened, we deployed all the resources within our capacity to address it and I think it was addressed maximally.

“I have not seen any operator complaining, except now that you are raising the issue, but as far as we know, call-masking is no longer a problem.

“I am going to contact our compliance monitoring to enlighten me about what is going on, but it is no longer an issue,” he said.

Mouka Reuben, director, Public affairs, NCC, said the situation has been tackled before and he does not think it was a major issue again.

He, however, promised that the commission would look into it again to find a way out.

NCC recently put the revenue lost to call-masking and SIM-boxing activities in the country at $3 billion.

This is as telecom operators lamented during the 85th edition of the Telecom Consumer Parliament in Lagos that they were losing about N2.5 million minutes per day to these fraudulent activities.

On actions that had been taken by the commission to combat the menace, Prof Umar Danbatta,  former Executive Vice-Chairman, NCC, said the NCC had tightened the SIM registration process across all networks to reduce the availability of SIM cards for SIM-boxing as well as address the security issues around the availability of pre-registered SIMs.

According to him, the action was necessary as some arrests made in Lagos two weeks ago showed that the perpetrators of SIM-boxing had over 100 SIM cards registered with fictitious names and used them to divert international calls.
