A rugged computer or ruggedized computer is a computer specifically designed to operate reliably in harsh usage environments and conditions, such as strong vibrations, extreme temperatures and wet or dusty conditions.[1] They are designed from inception for the type of rough use typified by these conditions, not just in the external housing but in the internal components and cooling arrangements as well.[2]

Typical environments for rugged laptops, tablet PCs and PDAs are public safety, field sales, field service, manufacturing, retail, healthcare,[3] construction, transportation/distribution[4] and the military. They are used in the agricultural industries, and by individuals for outdoor recreation activities.


Virtually all rugged computers share an underlying design philosophy of providing a controlled environment for the installed electronics. Rugged computers are engineered to operate in the face of multiple challenges including:

Electronic components themselves may be selected for their ability to withstand higher and lower operating temperatures than typical commercial components. Design engineering decisions such as reduction of cabling, addition of liquid cooling and heat sinks, and rugged materials, are made to ensure performance in harsh environments.

Features include fully sealed keyboards to protect against intrusion by dust or liquids, and scratch-resistant screens that are readable in direct sunlight.[5]

Rugged units have higher prices. However, one research study found that in environments where rugged computers are commonly used, total cost of ownership was 36% lower for rugged notebooks and 33% less for handhelds and PDAs, compared to conventional non-rugged versions. The lower overall cost is due to lower failure rates, the related impact on productivity, and other factors.[6]


A ruggedized laptop is built to operate reliably in dusty or wet environments and conditions. These computers have a thicker and stronger housing than a regular laptop, and are mainly used for industrial, construction and military purposes. Engineered to be mobile, they are vibration, shock, drop, and dust resistant, and waterproof, yet are able to comply with other important requirements such as high performance and governmental grade security. They are equipped with both current and legacy I/O ports including serial, ExpressCard, PCMCIA, VGA, and others that are commonly used in outdoor environments. The levels of ruggedization are not standardized, but they are measured by various certifications such as MIL-STD-810, IP, or ATEX.


A rugged computing tablet

A rugged tablet may be semi-rugged or fully rugged. The semi-rugged might have a protective case, rain-resistant body. Fully rugged tablets are engineered from the inside-out to work in extreme temperatures and other harsh conditions. They are designed to resist drops, shocks and vibrations while maintaining strength to be dust- and waterproof. A tablet has internally a solid state drive and no moving parts. Unlike many laptops, most tablets do not require a fan, improving their dust and water resistance. Many rugged ones have options such as a barcode scanner because they serve in the logistics and transport sector. Levels of ruggedization are measured by various certifications such as IP, MIL-STD-810 or ATEX.


A rugged and waterproof smartphone

A rugged smartphone has a thicker and completely sealed housing which protects it against all kinds of elements such as water, dust, shock and vibration. This kind of smartphone can be left out in a sandstorm, frozen in a blizzard or go underwater. A true fully rugged smartphone is substantially less susceptible to damage than a non-rugged smartphone. Like a rugged tablet, it typically meets IP certification and military standard specifications for dust, shock, vibration, rain, humidity, solar radiation, altitude and temperature extremes. Only a few manufacturers make a rugged smartphone due to its complicated structure, different use of material and high level of quality expectation. [7]

Some rugged smartphones have Push-to-Talk (PTT) capabilities, NFC and barcode reader functions which suit their use for industrial and construction logistics.

Wireless connectivity

Wireless capability is a key requirement for most enterprise mobility applications, and it has been reported that wireless-transmission failure rates are three times higher for non-rugged notebooks compared to rugged units.[dubious ] This difference is attributed to the greater experience of rugged-notebook vendors at integrating multiple radios into their products. Each transmission failure leads to five to ten minutes in lost productivity as the user has to re-login to the company network through a VPN.[6][failed verification]

Since enterprises are turning to cellular networks to enable full-time connectivity for their users,[9] major vendors of rugged computers offer both built-in wireless LAN and wireless WAN capabilities,[6][10][11][12] and partner with cellular carriers, such as Verizon and AT&T, as part of their offerings.[13][14] During the handoff between the various wireless LAN and wireless WAN connections, a mobile VPN allows the connection to persist, creating an always-connected infrastructure that is simpler for the user and eliminates application crashes and data loss.[15]
