Fuente: 3Com
Formato: PDF
Providing level of business-class performance in a wireless network required IT to proceed through an array of time-consuming, manual design and deployment steps followed by time-consuming management and troubleshooting to solve ongoing wireless network issues. The 3Com Wireless LAN Mobility System embeds intelligence directly into the network, enabling IT staff to automate the manual processes of the past and quickly design, deploy, and manage their wireless LANs. Using this structured approach to wireless LAN development, organizations of all sizes can quickly deploy the wireless environment that's best suited to meet their changing business needs.

Wireless VoIP: Ready For Prime Time

Formato: PDF
Voice-over-IP (VoIP, or voice delivered using the Internet Protocol) is gaining momentum as the benefits of the technology unfold. Lower costs, more advanced services, and the convergence of two traditionally separate networks into one make VoIP an option worth considering for most IT managers. VoIP is no longer a new technology, but instead is becoming a mainstream feature in telecommunications. This paper discusses the optimization of Global IP Sound's VoiceEngine in Pocket Presence's Running Voice IP on Intel's XScale Processor.

Wireless Wakeups Revisited: Energy Management for VoIP Over Wi-Fi Smartphones

Formato: PDF
IP based telephony is rapidly gaining acceptance over traditional means of voice communication. Wireless LANs are also becoming ubiquitous due to their inherent ease of deployment and decreasing costs. In enterprise Wi-Fi environments, VoIP is a compelling application for devices such as smartphones with multiple wireless interfaces. However, the high energy consumption of Wi-Fi interfaces, especially when a device is idle, presents a significant barrier to the widespread adoption of VoIP over Wi-Fi. To address this issue, the paper presents Cell2Notify, a practical and deployable energy management architecture that leverages the cellular radio on a smartphone to implement wakeup for the high-energy consumption Wi-Fi radio.

WLAN Vs. UMTS - The European Scene

Formato: PDF
This paper mainly looks at the different deployment schemes and rollout plans of UMTS and WLAN in Europe and the type of business models that operators and service providers are adopting. It also analyzes several competing or complementary technologies that could potentially alter the path for further development/ deployment of UMTS and WLAN services. More specifically, the paper discusses the technologies of "Voice over IP" (VoIP) and "Mobile over WLAN" through mobile devices, and the quasi-3G technology of EDGE, which could provide some of the same services as UMTS, but at a substantially lower cost.
