Insights

Retrofitting older hotel properties with wired network drops in every room can be costly and disruptive, especially during renovations or in buildings not originally designed for structured cabling. The GHP621W addresses this by offering the same core calling experience as its wired counterpart, the GHP621, but over a dual-band Wi-Fi 6 connection, letting properties deploy in-room phones without running new Ethernet cable to every location.

Its inclusion of push-to-talk and a proximity sensor also reflects design choices aimed at day-to-day convenience, allowing quick, intercom-style communication and smarter power or display behavior based on nearby activity.

Use Cases

• Hotel Rooms Without Ethernet Drops: Deploy reliable in-room phones over Wi-Fi 6 without new cabling.
• Renovated or Retrofit Properties: Add or replace room phones without disrupting existing network infrastructure.
• Hospitality Properties: Manage phones across many rooms with centralized GDMS provisioning.
• Hospitals & Care Facilities: Offer patients and residents a simple, wireless phone with quick-access programmable keys.
• Apartments, Dormitories & Retail: Equip shared spaces with dependable, easy-to-use wireless communication.

Is It Right?

This hotel phone is a great choice if you:

• Need to deploy phones in rooms without existing Ethernet wiring.
• Want the reliability and speed benefits of Wi-Fi 6 connectivity.
• Manage a hospitality property and want centralized provisioning across many rooms.
• Want more programmable keys than an entry-level hotel phone offers.
• Like the convenience of push-to-talk and proximity-based functionality.

You may want to consider another option if you:

• Already have Ethernet drops in every room and prefer the simplicity of PoE, in which case the wired GHP621 may be a better fit.
• Prefer a white finish, since the GHP621W comes in black (see the GHP620W for white).
• Require more than 2 SIP accounts for advanced call routing.
