Hytera make a number of both analogue and digital radios suitable for the hotel industry.
Small, rugged and compact and just what you need to enable efficient running of your hotel.
Imagine being able to ask your chamber maid in room 10 to add an extra pillow that the guest has just asked for at reception.
Well yes I suppose you could go upstairs and tell him / her, but that would take time, and your time is valuable.
Yes I suppose you could use a mobile phone, but aren’t you trying to discourage your staff from using their mobile phone?
Get a radio, be it Hytera or Entel (or another brand, which we can also supply).
