Wireless service providers in South Korea, Taiwan, Japan and China expanded their hotspot coverage, and they are planning to expand it even more Source: In-Stat & Infonetics Research Wi-Fi VoIP Market Drivers Growth of Wireless LAN and VoIP Buzz around dual-mode solutions among enterprises on synergy between IP PBXs and Wi-Fi LANs equipments. The leading WLAN apps will include wired LAN backup and asset and RF ID tracking Half of mobile subscribers would use their mobile as the main phone if service cost and quality were comparable to landline Wi-Fi VoIP Benefits End User Convenience – single device (convergence), single number, existing devices, easy add of new features, voice to data applications integration Services – presence, VXML, sound quality Cost savings – one device, single network charge, toll bypass Enterprise Single network, leverage existing network Cost control Productivity – reachability, toll bypass, maintenance Scaleable – (IP networks perception) Unified management Local network control (users, coverage, access) Mobile Carrier Increase Revenue • Capture landline minutes Improve Coverage • Leverage WLANs Lower Expenses • WLANs much less expensive than new cell phones Lower Churn • Offer differentiated service • Innovative price plans Wi-Fi VoIP Applications Market Segment: Enterprise and vertical markets implementation Target Users: Nurses, Teachers, Store clerks, Warehouse managers, IT managers, Construction workers Decision makers who need to always be available for quick responses Implementers who need to carry out tasks that requires mobility Wi-Fi VoIP Challenges WLAN Network Issues QoS Security Seamless Mobility Mobile Device Battery life must be maximized Price level Bandwidth management is required Call capacity should be maximized Standards compliance UMA – 14 major phone vendors and telecom operators push unlicensed mobile access (UMA) 802.11i, 802.11e, 802.11r, and 802.11s working groups actively working on technology to enhance Wi-Fi experience What’s Happening Today NTT DoCoMo in Japan already offering dual-mode phones from NEC KT Telecom in Korea offering service with hand-off between cellular and hotspots BT has trialed a Motorola dual-mode phone that uses Bluetooth to connect to an enterprise WLAN AVAYA, Motorola, and Proxim announced prototypes of its dual-mode WiFi/GSM GPRS Samsung introduced what it calls the world's first mobile WiMax handset. The Korean vendor is demonstrating WiBro, a Korean technology that is derived from the 802.16e spec that will form the basis of mobile WiMax, via the Samsung M800 handset model.
