Guide to Choosing the Best Grandstream Wireless Mobile Phones

Wireless mobile phones from Grandstream are an ideal choice for businesses seeking flexible communication without the constraints of wires. These phones rely on DECT and Wi-Fi technologies, allowing users to move freely within offices, warehouses, or even while working remotely.

What Are Wireless Mobile Phones? 

Wireless mobile phones are communication devices that operate without wires, providing users with freedom of movement during calls. These phones rely on two main technologies: 

  • DECT: A wireless technology dedicated to phones, offering a wide range and excellent audio quality. 

  • Wi-Fi: Enables connectivity through wireless internet networks, making it ideal for environments with strong Wi-Fi networks. 

Grandstream offers wireless phones in two series: WP (e.g., WP820 and WP825) and DP (e.g., DP720 and DP735), both designed to meet business needs in terms of flexibility, performance, and cost-efficiency.

  • Flexibility: They allow employees to move freely within offices or warehouses without being tied to a desk. 

  • Productivity: They facilitate quick communication in dynamic work environments such as hospitals, hotels, and warehouses. 

  • Cost-Effectiveness: Compared to traditional mobile phones, these phones offer lower communication costs through VoIP networks. 

  • Security: Call encryption using technologies like TLS and SRTP ensures the privacy of communications.
