Phones for extreme sportsmen and military men with walkie-talkies

The UHANS K5000 smartphone has undergone a rigorous test to determine its unsinkability.

Protected mobile phones are typically assigned an IPxxx rating, where the first digit represents the level of protection against foreign objects, and the second digit indicates protection against liquids. The Ingress Protection Rating (IP Rating) standard was developed by the International Electrotechnical Commission (IEC).

For mobile devices, the first digit of the IP Rating is either 5 or 6, while the second digit ranges from 4 to 8. Therefore, the highest level of protection according to this classification is IP68, and the lowest is IP54. Protected phones fall under the category of devices with IP68 and IP67 protection.

However, the U.S. Army’s MIL-STD-810G standard sets even higher requirements for devices:

• Temperature testing: the ability to withstand rapid temperature changes of up to 120 degrees Celsius per minute;
• Exposure to pressure up to 12,000 meters altitude;
• Exposure to radiation;
• Exposure to rain;
• Subjected to mechanical shock and drop;
• Subjected to pyrotechnic and ballistic impact;
• Exposed to freezing temperatures and icing;
• Subjected to vibration;
• Exposed to moisture, mold, dust, sand, acid, or a combination of adverse factors.

This military standard specifies a total of 29 rigorous tests.

Crash and drop tests

Many smartphone users enjoy conducting their own crash and drop experiments. They pummel their devices onto pavement and tiles, drive cars over them, impale them with nuts and hammer nails into them, shoot them, pour scalding water on them, and even submerge them in toilets. While most top-of-the-line models cannot withstand such abuse, rugged devices manage to impress even the most discerning “testers”.

Nevertheless, manufacturers kindly ask their customers not to perform such independent tests. It would be challenging to prove that the device was damaged due to a violation of the usage guidelines and secure a refund for the battered phone.

Powerful battery

A strong battery is a crucial feature of any smartphone and it always has an impact on its ranking. The ability to last for extended periods of time without needing to be recharged is particularly important for a rugged device. Whether you’re on a long journey, working on important tasks, participating in military operations or exercises, having a phone with a powerful battery is vital for maintaining autonomy. A two-day talk time and a month in standby mode are generally considered to be benchmarks for a robust battery.

Phones with walkie-talkies

• Free communication is possible if you have an autonomous walkie-talkie.
• Easy to use and convenient.
• You can send a message to a group on the same communication channel instead of just one person.
• Autonomous walkie-talkies have the same coverage area and service area, allowing communication where there is no cellular service.

For travelers, military personnel, and extremists, these communication capabilities can be essential.

Types of walkie-talkies in phones:

• PTT service. Subscribers can receive voice messages in a PTT group formed by them. This walkie-talkie function can be used in areas with a cellular connection, whether it’s their own or through roaming. To utilize the PTT walkie-talkie, users need a phone that supports this feature and a cellular operator that provides the service.
• Standalone walkie-talkie. The mobile walkie-talkie integrated into your phone allows you to stay connected even in areas without cellular service. It is completely self-sufficient and has a range of up to 15 km (professional portable stations can have a range of over 50 km).
• Internet walkie-talkie. A smartphone with internet access can be used as a walkie-talkie through applications like Zello and Voxer. These programs are free and available for both Android and iOS. They function as PTT radios, but require an internet connection.

Comparison with flagships

The performance of a smartphone is assessed based on its usability, processor power, RAM, and graphics processor performance. As a result, it is unlikely that a rugged device will appear at the top of AnTuTu or other benchmarks. The competition is fierce, and the “indestructible” smartphone has its own significant niche.

Not every device is capable of withstanding three 1-minute cycles of temperature change, ranging from -51 to +71 degrees Celsius. However, the most recent versions of the US military standard have introduced even tougher tests for “shock resistance” and vibration resistance. MIL-STD 810 has undergone 8 revisions so far, and it is becoming increasingly challenging to meet its requirements.

In recent times, the focus on safeguarding smartphones has increased for the most efficient and pricey models. Take, for instance, the iPhone 8/10, which possesses IP67 certification for protection. Similarly, the flagship Samsung Galaxy S9 adheres to the IP68 standard. However, Urban Armor Gear has gone a step further by developing impact-resistant cases for iPhones that fulfill the expectations set by the MIL-STD 810G military standard. While this is undeniably an answer to the protection dilemma, it is still a somewhat incomplete solution.

Simple rugged phones: with and without a walkie-talkie

For individuals leading an active lifestyle, the device’s functions become crucial, which may be easily overlooked in a bustling city environment. While 3D games may take a backseat, a powerful flashlight takes center stage. Take, for instance, the Crosscall Shark-X3, a standard IP68 phone developed by the French company Crosscall.

It’s more than just a smartphone; it boasts capabilities that even high-performance devices cannot replicate. Thanks to its advanced technology, this device:

• Is waterproof and won’t sink
• Emits sound and light signals if immersed in water
• Features a robust LED flashlight
• Includes a red LED flashlight for nighttime map reading
• Has a 3G module, enabling the phone to serve as a modem for internet access via a camping tablet
• The device is equipped with a highly audible whistle, ensuring safety in bear encounters.
• Its class-leading 5 MP camera and 950 MA battery make it a standout in its category.

Despite not having a walkie-talkie feature, this simple yet in-demand device has found popularity among hunters and fishermen. While it may not directly align with the article’s theme, when used as a modem alongside a laptop and tablet, it can function as a zello-radio.

Smartphone or phone?

Rugged smartphones are outperforming flagship smartphones not only in terms of durability but also in performance. The small display of a button phone gives it an edge over large touchscreens when it comes to durability. Furthermore, button phones consume less energy and, therefore, can last longer on the same battery capacity. This also contributes to their faster performance in comparison to smartphones. Plus, button phones are much more cost-effective.

However, there are numerous tasks in extreme and challenging environments that cannot be handled by a simple button phone. Finding a button phone equipped with GPS is not an easy task, whereas finding a smartphone without GPS is even more difficult. A smartphone is akin to a personal computer, as its functionality can be expanded through the use of useful software. Using the internet and Wi-Fi on a regular phone is inconvenient and inefficient. Additionally, regular phones lack the multitasking capabilities that are mandatory for smartphones.

In emergency situations, a rescuer from the Emergency Situations Ministry requires a multifunctional and robust device, while an amateur fisherman may prefer a cheap and minimalist button phone that is still impenetrable and unsinkable.
