Scope / deliverables
- WL4 vs DECT difference: WL4 operates over existing WLAN (Wi-Fi) infrastructure — no separate DECT base station needed; registers directly to PBX via SIP; DECT handsets connect via BSIP2 base station, WL4 connects via access point
- IEEE 802.11 a/b/g/n/ac support (2.4GHz and 5GHz), WLAN security: WPA2-PSK, PEAP-MSCHAPv2, EAP-TLS, AES-CCMP (802.11i/w), fast roaming: 802.11r/k, PMKSA caching, CCKM; IP44 enclosure
- Protocols: SIP/RTP, SRTP/TLS (encrypted voice), TCP/IP, DHCP, DNS, SNMP; voice codecs: Opus Wideband, G.711 A/μ-law, G.729, G.722; 4 network profiles (auto/manual selection)
- Physical: 137×52×21mm, 135g, TFT 240×320 pixel 2" display, Li-polymer 3.7V 920mAh, 3.5mm headset, HAC compliant, vibration alarm; operating -5°C~+45°C
- WL4 — basic VoWLAN: 250 local / 1,000 company phonebook / LDAP access, 25 call list; with messaging license: max 160 chars, 30 message capacity
- WL4 Plus — additional features: man-down alarm, no-movement alarm, push-button alarm — automatic call after alarm, acoustic location signal; full OScAR alarm server integration
- Tested platforms: OpenScape Business V3+, OpenScape 4000 V8+, OpenScape Voice V9+ — SIP connection
- WSG Server: 44×220×199mm, 1× LAN, 1× mini-USB, wall or 19" rack mount, 100-240VAC; central WL4 phonebook (1,000 entries), OTA config+update, OScAR alarm handling, LDAP integration; 0°C~+40°C, IP30
- Applications: healthcare (nurse/doctor calls, man-down — WL4 Plus), retail (store coordination), logistics/manufacturing (in-plant VoWLAN), office campus (leverage existing Wi-Fi investment)
- Promark: WLAN coverage analysis, WSG installation+configuration, SIP/PBX integration, OScAR alarm connection, charging equipment supply
