DECT vs. Wi-Fi Phones: Which Is Better for Your Business?

Today, employees don't always work at their desks. They may move around the office, work in different rooms, or need to answer calls while helping customers.

Businesses need phone systems that allow employees to stay connected wherever they are.

Two popular wireless phone solutions are DECT cordless phones and Wi-Fi phones. Both allow employees to make and receive calls without being tied to a desk. However, they work differently, and each has its own advantages.

Let's take a closer look to help you choose the right solution for your business.

1. DECT Cordless Phones: Reliable and Easy to Use

DECT cordless phones work much like traditional cordless home phones. They connect to a dedicated base station ( that communicates with the handsets wirelessly. DECT technology is designed specifically for phone                                     

calls, making it a reliable choice for businesses that need clear and stable voice communication. The picture on the left shows the Yealink W76P High-Performance DECT IP Phone System, which includes a base station and a cordless handset.

Advantages of DECT Phones

• Reliable call quality: DECT uses a dedicated wireless frequency for phone calls, helping reduce interference from other devices.

• Easy to set up: A small office may only need one base station and a few handsets.

• Good wireless coverage: Additional signal repeaters or multiple base stations can help cover larger areas.

• Ideal for mobile employees: Staff can answer calls while walking around the office, warehouse, store, or clinic.

Disadvantages of DECT Phones

For a small business, DECT is usually affordable and straightforward.

However, when a business needs hundreds of handsets across a large building, the cost can increase significantly. More base stations, additional equipment, and more complicated installation may be required.

DECT is a great choice for small and medium-sized businesses that want reliable wireless phone service.

2. Wi-Fi Phones: A Flexible and Cost-Effective Solution

Wi-Fi phones connect to the same wireless network that businesses use for computers, smartphones, and other devices. If your office already has a good Wi-Fi network, you may be able to use it for wireless phone calls without installing a separate DECT system.  The picture left is WP836 Wi-Fi 6 Rugged IP Phone from grandstream.  

Advantages of Wi-Fi Phones

• Lower installation costs: You may be able to use your existing Wi-Fi network.

• Less equipment: No separate DECT base stations are needed.

• Flexible deployment: Employees can move around the office while staying connected.

• Easy to expand: Adding more phones may be simpler when your wireless network already supports them.

• One network for multiple purposes: Your business can use the same network for computers, mobile devices, and phone calls.

Disadvantages of Wi-Fi Phones

Wi-Fi phones depend on the quality of your wireless network.

If the Wi-Fi signal is weak, too many devices are connected, or the network is not properly configured, call quality may suffer. Calls may experience delays, interruptions, or poor audio.

The good news is that modern Wi-Fi equipment offers better ways to manage voice traffic and improve call quality.

Wi-Fi phones are a good choice for businesses looking for flexibility and a cost-effective way to support wireless communication.

3. How Can Wi-Fi Call Quality Be Improved?

Wi-Fi phone calls need a stable and reliable wireless connection.

A technology called Quality of Service (QoS) helps the network prioritize phone calls over less time-sensitive activities, such as downloading files or browsing websites.

For example, when employees are making phone calls while other staff are using computers, the network can give voice traffic higher priority.

Grandstream's GWN Wi-Fi access points are designed to support business networking and wireless voice applications. With the right network equipment and configuration, Wi-Fi phones can provide call quality that approaches that of a multi-base-station DECT system. Explore Grandstream Wi-Fi networking products:

5. Which Wireless Phone Solution Is Right for Your Business?

There is no single solution that works best for every business.

• Choose DECT phones if you want reliable wireless calling with a dedicated phone system, especially for smaller deployments.

• Choose Wi-Fi phones if your business already has a strong Wi-Fi network and you want a flexible, potentially more cost-effective solution.

• For larger businesses, consider your building size, number of employees, wireless coverage, and installation budget before making a decision.
