IP Office WiFi or IP Office DECT?

Telefonix Voice & Data can do both IP Office WiFi and IP Office DECT solutions to meet a variety of needs, allowing you to select the best choice for your needs.

An IP Office DECT network offers a secure, dedicated voice-only network in an assigned frequency band to minimize or eliminate interference. It also requires significantly less planning and is consequently more easily scalable. DECT handsets tend to be low-cost. However, since it is optimized for voice, DECT offers lower data bandwidth to the handsets making it appropriate for basic, text-based applications. DECT requires installing and maintaining a separate wireless network. DECT should be considered for environments containing many other types of wireless devices, such as RFID equipment or scanners, which may interfere with each other.

An IP Office WiFi phone network offers a converged voice and data network, requiring maintenance of only a single network. WiFi handsets offer higher data bandwidth. However, with WiFi, handsets may be a more significant cost and require additional planning to ensure optimal voice quality and coverage, compared with DECT. Due to differences in the radios and algorithms, WiFi handsets also offer less standby/talk time when compared with DECT.
