Waiter call: ivory 3-key table button (waiter, bill, cancel) and a waiter pager showing a TABLE 12 call

Overview

The problem in the field. At hotels and resorts, guests are on the beach, by the pool, in the garden or on the terrace, and the waiter is out of sight. Short-range call systems do not reach the beach; Wi-Fi based solutions struggle with coverage and battery life; raising a hand or shouting lowers the quality of service. Management has no idea how many seconds it takes to answer a call.

The solution. Every table, sun lounger or room gets a battery-powered call button; when a guest presses it, the call appears on the central display and on the pager of the waiter responsible for that area. The current-generation system works with a range of 100–200 m and shows the table/room number and call priority. The new generation aims to cover the indoor areas and the beach with a single gateway or one repeater thanks to long-range LoRa, to broadcast the waiter's acknowledgment to the other pagers and the display as "received", and to log call times for shift reports.

Application profiles. Single-button (call), three-button (call / bill / cancel) and six-button (menu-specific) versions; in the new generation, an IP65, UV-resistant sun-lounger button and a wall-mounted room/VIP button. The same button platform is also used for taxi calls, guard alarms and forklift/operator calls: Wireless Call Button Platform.

Applications

  • Hotels and resorts
  • Beaches and beach clubs
  • Pool and garden areas
  • Restaurants and cafés
  • Tennis, golf and sports clubs
  • Corporate dining and protocol halls
  • Convention centers
  • VIP lounges
  • Forklift / operator call

Waiter calling is one of the profiles of the Wireless Call Button Platform; the same button hardware is also used for taxi calls, guard alarms and industrial forklift/operator calls. In the new generation, broadcasting the waiter's acknowledgment to the other pagers relies on the acknowledgment (ACK) broadcast feature of the WR-001 LoRa Wireless Alarm / Call Remote.

Frequently asked questions

Will a call from the beach reach a waiter indoors?

The current-generation system has a range of 100–200 m. The new generation aims to cover the hotel building and the beach on a single network with long-range LoRa and, if needed, one repeater (≥ 1 km in open field).

How long does the button battery last?

The new generation targets ≥ 2 years at ~20 calls a day (CR123A or 2×AA); low batteries are listed at the central unit.

How do I know the waiter has received the call?

In the new generation, the waiter acknowledges on the pager; the acknowledgment is broadcast to the other pagers and the display, and the LED on the guest's button shows "received".

How many tables and waiters are supported?

The current generation has no limit on the number of handsets (pagers). The new generation targets ≥ 500 buttons and ≥ 32 pagers per network.

Can it interfere with a nearby venue's system?

No; every facility has its own network ID and packets with a different ID are ignored.

Is a central display required?

No. In the new generation's standalone mode, buttons go straight to the pagers; a display or PC is added for reporting and management.

Are mobile notifications available?

Push notifications through a local server or the cloud are planned for the new generation.

What about warranty and service?

2-year warranty; manufacturing and service in Ankara. Batteries and spare buttons are available from stock.
