DECT and VoWLAN

Comparison

DECT VoWLAN CUSTOMER CONSIDERATION

Optimized for voice; limited data capabilities Supports voice and data on one network VoWLAN requires careful deployment and

capacity planning,

DECT is relatively a simple installation

Dedicated frequency band at 1.9 GHz; marginal

interference

802.11 networks in the 2.4 GHz band;

802.11a/h/n in the 5 GHz band

Dedicated frequencies help isolate interference

Mature and robust mechanisms for roaming,

handover, encryption & security

Established protocols for roaming and

handover; open security standards exist.

Security should not be sacrificed when roaming or

when calls change access points or nodes to

maintain communication

Quality of Service is uniform

Quality of Service influenced by network traffic,

CAC capability

QoS guarantees are important to ensure a high

standard of performance, particularly if network

capacity is insufficient

Supports 120 non-overlapping channels Supports 11 to 13 channels

19 channels in EU with 802.11a/n

More channels will ensure your signal and quality

of communication are stable

Typical standby time is 150 hours, and typical

talk time (battery) is 50 hours

Maximum standby time is up to 80 hours, and

maximum talk time is up to 8 hours

Longer battery life enables workers to be

productive longer and helps reduce dropped calls

Range of 300 meters Range of 30-150 meters for 802.11 networks

An extended range for your phones will ensure less

calls are dropped and will allow workers to be more

flexible with mobility
