Rugged Computers are More than Just ‘Hard Shells’

First of all, let us distinguish between a “rugged” computer and a “ruggedized” computer (or tablet or smartphone).

A rugged computer is designed to operate reliably in very harsh environments and conditions. The term “ruggedized” gives the sense that fragile internal components have been somehow protected. Truly rugged devices are not simply wrapped in a tough shell.

Tough and durable mobile computers and smartphones are gaining in popularity – because the customers demand more durable products! – and there are actually some mainstream devices that could be described as  ruggedized (and are often advertised as rugged). But they are not truly rugged.

They might be waterproof but lack other aspects of ruggedness, like the ability to withstand vibrations/shocks and function well in extreme temperatures.

Let us briefly recap the definition of ruggedness:

The devices should have passed some of the MIL-STD tests, i. e. the American military standard for equipment.

24 laboratory test methods ensure that the equipment can handle low pressure at high altitudes; exposure to high and low temperatures plus temperature shocks; rain; humidity; sand and dust exposure; leakage; shock and vibration.

•  They must be highly rated on the ingress protection (IP) scale for protection against dust and liquids. The ratings are displayed as a 2 digit number.

The first digit reflects the level of protection against dust and the second digit reflects the level of protection against liquids (water). So an IP65 rating, for example, would ensure complete protection against dust and protection against water jets.

Now let us take a closer look on the tests carried out on rugged computers:

Drop and shock testing. This is one of the most important tests for rugged computers, simply because rugged computers are dropped all the time by workers in the logistics, forestry, public transportation, construction, mining, security and other industries where rugged computers are in high demand.

Drop a normal computer and you will easily break the display or the hard drive. Drop a rugged computer and nothing will happen – at least it is highly unlikely that the device will break if it has passed all the relevant tests.

All rugged mobile computers are tested to ensure they can survive falls as well as high-force impacts to the devices’ casings. Drop tests are certified by independent test laboratories and performed in accordance with MIL-STD-810G.

There are eight different procedures to choose from that each use different ways to cause shock or impact.

The “transit drop test” is the most cited. It requires items to survive a total of 26 drops from the height of 122 cm, on each face, edge and corner, onto a hard surface like concrete.

Liquid resistance testing. Mobile field computers are inevitably exposed to rain, spills and splashes. The second number of the IP code describes the liquid ingress protection, i.e. how well the unit is protected against water.

The scale ranges from dripping water to continuous immersion in water. Water resistance tests are often carried out by the manufacturers of rugged computers by exposing the computer to powerful water jets from many directions without harmful effects.

The test duration, water volume and water pressure varies depending on the rating. The water temperature is lower than the device.

 Vibration testing. Ordinary mobile computers are sensitive to vibrations and are not built to handle vibrations. Hard drives disks are especially vulnerable when subjected to vibration. Rugged computers, however, must be able to handle vibrations since they are often used in vehicles that travel on bumpy and rough surfaces.

Vibration tests are performed in accordance with MIL-STD-810G. They are designed to determine if a device can withstand the vibrations it would be exposed to during its lifecycle.

The tests use laboratory shakers set to different levels to simulate being on a vehicle or carried by a person, with variations in the vibrations’ wave form, frequency and intensity depending on the type of device and the environment being simulated.

 Sand and dust testing. A rugged computer must be able to keep out particles. Almost all field workers are exposed to dust and dirt at some point that would slow key functions and damage components if not protected.

 The dust resistance procedure tests ingress of small dust particles. Flour and sand is projected onto the device at high wind speeds and high temperatures for several hours, rotating the device and varying the temperature and wind speed.

 The blowing sand resistance procedure is basically the same as the dust test but the test is done in higher wind speed. The high end test simulates being near an aircraft.

Extreme temperature testing. Rugged mobile computers must be able to handle extreme temperatures and wild temperature swings.

For example, Handheld’s recently launched Nautiz X1 smartphone is designed to function well in temperatures ranging from -20°C to 60°C (-4°F to 140°F).

High temperature and low temperature tests are conducted in accordance with MIL-STD-810G. When testing for operability during high temperatures, the devices exposed to high temperatures while it is turned off (storage), while being turned on used (operation), and how it works under operational temperatures after having been exposed to higher storage temperatures (tactical-standby to operational).

 When testing for operability during low temperatures, again three procedures are carried out to determine how the device will behave in low temperatures. They are much the same as in the high temperatures tests, except being done in freezing conditions.

 Humidity testing. In addition to liquid resistance testing for IP rating, many manufacturers of rugged mobile computers test their devices in highly humid conditions as a separate test that is defined by the MIL-STD-810G standard.

The computers are exposed to humidity well over 90 per cent for several days in tropical heat. Many of the same features that make mobile computers liquid resistant also help prevent damage from high humidity.

These are the most important tests. The next question is: how do manufacturers of rugged mobile computers actually make their devices touch enough to pass these tests?

§  As opposed to normal computers, most rugged computers have no moving parts inside, like fans or rotating hard drives. Instead of rotating hard drives, rugged computers have solid-state drives – drives without moving mechanical components that are more resistant to physical shock.
§  There are stiffeners inside a rugged computer, often made out of aluminium, to prevent inside components and boards from flexing during an impact. The outer shell (case) and bumpers are designed to absorb the energy from a drop to prevent internal damage.

§  The touchscreen of a normal smartphone or computer is basically glass (with some coating to make them sensitive to touch), whereas the displays of rugged computers use chemically strengthened glass to prevent against scratches and cracks. The displays can also be positioned lower than then surrounding case to decrease their vulnerability.

§  Display backlight is used to improve outdoor readability, even in direct sunlight.

§  Some rugged computers are fitted with internal heaters in order to operate successfully in very cold environments. The heater warms components to an acceptable operating level and eliminates condensation arising from temperature swings.

In short, every simple detail and small part is researched, developed and chosen to make the computer as rugged as possible.

So where does all this leave us? Well, it is important to know the ingress protection scale – the higher the numbers, the tougher the device, basically.

‘ It is also instrumental to check that the unit has undergone MIL-STD tests – many devices boast good IP numbers but fail to inform customers that they have not gone through any MIL-STD tests (which basically makes them normal fragile computers that are somewhat dust and water resistant).

With a deeper understanding of the standards and the tests, it will be easier to choose the mobile rugged device that suits your unique needs.

And if you want a rugged computer – then do not buy a ruggedized computer. Rugged computers are built—inside and out—to be rugged. No fragile parts wrapped in a hard shell here.

FCCPC Denies Banning Airtime Borrowing, Blames Cartel for Misinformation

Published

Kindly share this post

Federal Competition and Consumer Protection Commission (FCCPC) has dismissed widespread claims that it banned airtime borrowing and data advance services in Nigeria, describing the reports as false and driven by vested interests seeking to mislead the public.

FCCPC Denies Banning Airtime Borrowing, Blames Cartel for Misinformation

In a statement issued on Friday, the commission said it neither cancelled nor prohibited such services, contrary to viral social media posts and some media reports suggesting otherwise.

The clarification follows a wave of public concern triggered by viral social media posts and some media reports suggesting that the Commission had shut down telecom-based credit services widely used by millions of Nigerians.

Recall that in separate notices, Airtel and MTN Nigeria announced the temporary suspension of their airtime and data credit services, which previously allowed eligible prepaid customers to borrow airtime or data and repay on their next recharge.

But FCCPC, said no such directive was issued, stressing that consumers remain free to access lawful telecom value-added services.

Ondaje Ijagwu, director of Corporate Affairs, FCCPC, said that “The attention of the Federal Competition and Consumer Protection Commission has been drawn to a series of newspaper publications and a viral anonymous post on social media seeking to create the impression that the Commission cancelled, shut down, or banned airtime borrowing and data advance services in Nigeria. Those claims are incorrect.

“The Commission has not prohibited airtime borrowing or data advance services, and no directive was issued preventing consumers from accessing lawful telecom value-added services,” the statement partly read.

Rather than a regulatory ban, the FCCPC attributed recent disruptions in some of these services to the failure of certain operators to comply with its Consumer Lending Regulations introduced in July 2025.

According to the Commission, the regulations were developed following a surge in consumer complaints over exploitative practices in the digital lending and advance-services space.

“Following a deluge of consumer complaints bordering on opaque charges, unexplained deductions, aggressive recovery practices, poor disclosure standards, and inadequate accountability in segments of the digital lending and advance-services market, the Federal Competition and Consumer Protection Commission issued the DEON Consumer Lending Regulations in July 2025.

“The Regulations were introduced, among other reasons, to curb the excesses of abusive service providers whose practices had generated persistent consumer harm and undermined confidence in the market,” it stated.

The agency said the framework was designed to sanitise the market and protect consumers by enforcing transparency, accountability, and fair competition.

“The primary aim is to promote a fairer and more transparent system by mandating proper registration, responsible lending conduct, clear disclosure of fees and terms, accessible consumer complaint channels, data protection safeguards, stronger accountability for third-party partners, and effective regulatory oversight,” the FCCPC explained.

Providing a deeper insight into the telecom sector, the Commission revealed that some operators had been engaged in anti-competitive practices, including exclusionary arrangements with third-party service providers.

“In the telecom sector, our findings indicated that some operators engaged in exclusionary third-party technical arrangements in clear disobedience to the provisions of the Federal Competition and Consumer Protection Act, 2018. The Regulations sought to unlock the market to allow local participants alongside foreign partners, in line with free market principles,” it said.

It added that the new regulations were also intended to open up the market to more participants, including local players, in line with free market principles.

Despite giving operators ample time to comply, the FCCPC said several companies failed to align with the new regulatory framework.

“These measures benefit Nigerians by reducing abusive practices, improving transparency, strengthening consumer choice, and encouraging responsible innovation by legitimate operators. At the commencement of the framework in July 2025, affected operators were granted an initial 90-day compliance period to regularise their products, structures, and operations. That opportunity was not utilised within the prescribed timeframe,” the statement noted.

The Commission said it extended the deadline to January 5, 2026, but compliance remained unsatisfactory.

“Despite that further extension, the necessary compliance steps were still not completed by the relevant operators,” it added.

The regulator stressed that any temporary suspension or restriction of services should be seen as a business decision by non-compliant operators rather than a government-imposed ban.

“Any temporary suspension, restriction, or operational change introduced by service providers should therefore be understood as a business or compliance decision by those operators, not a ban imposed by the FCCPC,” it said.

The Commission also accused certain interest groups of deliberately spreading false information to undermine reforms.

“We are aware that some vested interests and their foreign collaborators are opposed to the creation of safe markets and fair competition, therefore resorting to a campaign of disinformation,” it stated.

Describing such narratives as “mischievous,” the FCCPC urged Nigerians to disregard sensational claims and rely on verified information.

“It is inaccurate to attribute avoidable disruption to regulation where regulated entities had adequate notice and sufficient opportunity to comply. Nigerians deserve accurate information, not sensational claims.

“The FCCPC is fully committed to protecting consumers, promoting fair competition, encouraging responsible innovation, ensuring transparent digital financial practices, and working constructively with sector regulators and service providers in the public interest,” the statement added.

Airtime borrowing and data advance services have become critical tools for millions of telecom subscribers in Nigeria, allowing users to access credit for calls and internet services with repayment deducted upon recharge.

However, the segment has long been plagued by complaints over hidden charges, automatic deductions, unclear repayment terms, and aggressive recovery mechanisms.

The FCCPC’s intervention through the Consumer Lending Regulations marked one of the most significant attempts to regulate digital micro-lending and telecom-based credit services in the country.

The rules align with broader efforts by the Federal Government to strengthen consumer protection, enhance transparency in digital financial services, and curb exploitative practices in Nigeria’s rapidly expanding fintech and telecom ecosystem.

Friday’s clarification signals a push by the regulator to reclaim the narrative, reassure consumers, and shift responsibility to operators who have yet to fully comply with the law.

The Commission reaffirmed its commitment to protecting consumers while fostering innovation and fair competition in the sector, noting that regulatory compliance remains non-negotiable for all service providers operating in the Nigerian market.

National Information Technology Development Agency (NITDA) has urged young Nigerians to take the lead in developing home-grown artificial intelligence (AI) solutions to address the country’s socio-economic challenges.

NITDA Urges Youths to Build Nigeria’s AI Future Now

The Director General of National Information Technology Development Agency, Kashifu Inuwa, represented by Mrs. Udoka Mannie of the Digital Literacy and Capacity Building Department, delivered the keynote address at the Artificial Intelligence Hackathon organised by the Agency in partnership with VibeCode Africa in Abuja.

Kashifu Inuwa, director-general of NITDA, made the call at an Artificial Intelligence Hackathon organised by the agency in partnership with VibeCode Africa in Abuja.

Inuwa, who was represented by the Acting Director of Digital Literacy and Capacity Building, Dr Ahmed Tambuwal, and delivered through Mrs Udoka Mannie, said Nigeria’s youthful population presents a significant opportunity for innovation and digital transformation.

He noted that with over 60 per cent of Nigerians under the age of 25, the country is well positioned to benefit from emerging technologies such as AI.

“As you can see, this room is filled with young people. This represents a powerful opportunity for innovation and digital skills development,” he said.

Inuwa stated that the hackathon provided a strategic platform for participants from diverse backgrounds to collaborate and develop practical AI-driven solutions tailored to Nigeria’s realities.

He observed that artificial intelligence is already transforming economies, governance systems and societies globally, stressing that Nigeria must decide whether to shape the technology for national development or remain a passive consumer.

According to him, NITDA’s mandate is to regulate and develop information technology in Nigeria while ensuring it serves as a driver of economic growth.

He explained that the agency’s Digital Literacy and Capacity Building Department is focused on building a digitally skilled population capable of competing in the global digital economy.

The Director-General highlighted the Digital Literacy for All initiative (DL4ALL) as a flagship programme aimed at equipping millions of Nigerians with essential digital skills, in line with the Federal Government’s target of achieving 95 per cent digital literacy by 2030.

“Beyond literacy, we are now moving into capability. It is one thing to use technology, but another thing entirely to build with it. Today, we are challenging you to build,” he said.

Inuwa urged participants to prioritise impact-driven innovation, identifying sectors such as healthcare, agriculture, education, financial inclusion, public service delivery and misinformation as areas where AI can drive meaningful change.

He also stressed the importance of ethics, inclusion and data protection in the development of AI solutions.

“As we explore AI, we must be mindful of ethics, data protection and inclusion. Building responsibly is just as important as building brilliantly,” he said.

Inuwa commended VibeCode Africa for partnering with NITDA, describing such collaborations as vital for scaling innovation across the country.

He encouraged participants to collaborate, experiment and innovate, adding that Nigeria’s AI future would be driven by local talent.

“The future of AI in Nigeria will not be imported. It will be built by people like you in rooms like this,” he said.

In her remarks, the founder of VibeCode Africa, Lola Adey, urged participants to harness AI to solve real-life challenges within their communities.

Adey said the hackathon was designed to move beyond theory by encouraging participants to identify problems they personally experience and develop practical solutions.

“We want you to dig deep into yourselves. What are the problems you are facing? What are the issues you notice when you walk around?” she said.

She cited challenges such as electricity shortages, insecurity and gaps in social services as areas where innovation could make a difference.

Adey added that the initiative aims to create opportunities for entrepreneurship, employment and global exposure for young Nigerians.

“With artificial intelligence, you now have something in your hand that you can use to actually solve problems. You don’t have to wait for anybody anymore,” she said.

She urged participants to remain focused, collaborative and open to learning, noting that the platform could connect them to future partners, investors and employers.
