Before you even look at a phone, you must understand where people will use it. What kind of environment will the handset face? Is it extremely hot or cold? Will it get wet or dusty? Answering these questions helps you choose the right level of ruggedness.

 

First, conduct an in-depth analysis of your operational environment. Think about the specific tasks workers perform and what they need from a device. What works for a field sales team might not suit a manufacturing plant.

 

Next, evaluate the technical specifications. Consider processor speed, memory, storage, and connectivity options. These factors are crucial for the device’s performance. You also need to assess the device’s durability. Look for resistance to dust, moisture, shock, and extreme temperatures. Different levels of ruggedness exist, from “ruggedized” to “ultra-rugged,” each suited for varying challenges.

 

Manufacturers test rugged devices against strict standards to prove their toughness. For example, MIL-STD-810G is a U.S. Department of Defense standard that tests equipment in harsh conditions. This includes methods for:

 

 

• High Temperature (Method 501.4): Devices perform in heat up to +71°C, like in deserts or engine rooms.

 

• Low Temperature (Method 502.4): They work in extreme cold, down to -57°C, for arctic regions.

 

• Humidity (Method 507.4): Tests check for moisture absorption and corrosion over 10–15 days at high humidity.

 

• Salt Fog (Method 509.4): This simulates marine conditions, exposing equipment to salt spray for days to check corrosion.

 

• Sand and Dust (Method 510.4): Devices face fine or coarse particles blasted at high speeds to test against ingress and abrasion.

 

• Vibration (Method 514.5): Tests ensure durability against vibrations from transportation like ships or vehicles.

 

• Shock (Method 516.5): This measures survival during impacts, including drops and crash loads.

 

 

Another key specification is the Ingress Protection (IP) rating. This rating tells you how well a device resists dust and water. For instance, an IP68-rated device is dust-tight and can handle submersion in water beyond one meter. A higher number means better protection. Manufacturers also test drop resistance, checking how high a device can fall onto concrete without damage.

 

Understanding Connectivity Options for Industrial Use

 

Reliable connectivity is the backbone of any communication system. Rugged industrial telephone handsets offer various options to keep your team connected, whether they are on the move or at a fixed station.

 

Many modern rugged cordless IP phones use Wi-Fi or DECT (Digital Enhanced Cordless Telecommunications) for mobility. For example, models like the Grandstream WP825 only need a Wi-Fi AC connection, eliminating the need for a central base. Other devices, such as the Snom M70, M80, and M90, are industrial cordless IP DECT handsets. They often meet MIL-STD-810G standards for durability. You can connect multiple cordless handsets to a DECT base station, like the SNOM M900, which uses professional multi-cell DECT technology for wider coverage.
