Secure communication inside buildings requires first-rate infrastructure

Wireless voice communication with text, messages and alarms integrated. We have strong and well-proven products, including the possibility of RFID-based indoor positioning.
The choice of communication technology for indoor environments is today more difficult than ever! VoWiFi or DECT, maybe even GSM? We don’t believe that there is a given technology and say use the technologies for what they are made for, feel free to mix.

DECT is superior for speech and alarms.
WiFi is great for broadband applications such as data, video etc.
NFC is good for some applications such as presence, access and payment applications.
Bluetooth is good for cutting the cable to headsets.
BLE is good for wireless communication between a phone and a battery-powered application such as a beacon.
RFID is good for short distance fast communication such as precise positioning.
GSM is terrible if you are out and about, but not if you are 100% in a building.
