Wireless Phones and DECT Systems

DECT and Wi-Fi handsets, a multi-cell DECT base and a radio-over-IP gateway in one range. The table shows how the five differ on radio, capacity and battery.

  • DECT handsets and Wi-Fi handsets in one range
  • Multi-region DECT band support on the W610D
  • IP67 protection on the W611W
  • Wi-Fi 6 dual-band radios on the W611W and W620W, with 802.11k/v/r roaming on the W611W
  • A multi-cell DECT base for up to 300 handsets and 200 simultaneous calls per system
  • A RoIP gateway that bridges UHF 400–470 MHz radios to SIP calls
  • PoE on the DECT base and the RoIP gateway

DECT or Wi-Fi — the first decision

Both routes end as SIP extensions on the same PBX. The question is what carries the last few metres: a dedicated DECT radio with its own base stations, or the wireless network that is already installed.

  • DECT: W610D handset on a DECT base, with bands supported for America, Europe, Japan, Taiwan and Brazil
  • Wi-Fi: the W611W and W620W register over the LAN, so coverage follows the wireless design
  • W611W carries IP67 protection and 802.11k/v/r roaming; W620W carries the larger battery and video preview

How the numbers scale

Handset counts are quoted per base and per system, which is what decides the number of bases on a site.

  • W710H: up to 30 handsets and 16 simultaneous calls per base
  • W710H system: up to 300 handsets and 200 simultaneous calls
  • Coverage per W710H base: up to 100 m indoors and 700 m outdoors (US figures; EU 60 m and 350 m)
  • One base in the same range is documented for up to 10 W610D handsets and 10 simultaneous calls

Battery figures are lab data

Talk and standby times in this range are quoted as internal lab test data, and they differ between models because the batteries differ.

  • W610D: up to 8 h talk / 160 h standby
  • W611W: 1900 mAh, up to 9 h talk / 200 h standby
  • W620W: 3000 mAh, up to 13 h talk / 240 h standby
  • Real-world time depends on use; each model page lists its own documented figures

Frequently asked questions

DECT or Wi-Fi — which should we specify?

DECT gives you a dedicated radio band and your own base stations, which suits sites that need predictable coverage and high call counts. Wi-Fi handsets use the wireless network already installed, which suits sites with good Wi-Fi and staff who need data devices too. Both register as SIP extensions on the same PBX.

Why do the battery figures differ between models?

Because the batteries differ. The W610D is quoted at 8 h / 160 h, the W611W at 9 h / 200 h from a 1900 mAh battery, and the W620W at 13 h / 240 h from a 3000 mAh battery. All the figures are internal lab test data; real time depends on use.

How many bases will our building need?

That depends on the site. One W710H base is documented for up to 30 handsets and 16 simultaneous calls, with coverage up to 100 m indoors (US figures). Tell us the floors, the walls and the handset count and we will size the system.

Can we bridge an existing radio fleet to the phone system?

Yes — that is what the W712 RoIP gateway does. It carries a UHF 400–470 MHz radio module and speaks SIP, with group calls between radios and SIP phones.
