The first is during the state when a phone is kept ‘on’ and is waiting for a call. The power consumed in this mode will determine the standby time of the phone. The second mode is during an active call, which would determine the talk time of the phone. Active voice calls use standards-compliant powersave modes such as U-APSD, where the WLAN device enters a low-power state in the duration between transmissions of voice packets. Data download, upload—Transfer speed is the primary performance metric of data transfer applications. This data rate is influenced by the location of the handset with respect to the AP, the performance of the receiver in its ability to handle weak and distorted signals, and the power and quality of its transmitted signals. Interestingly, the higher the performance, the lower is the energy consumed for transferring a desired amount of data. This is because the WLAN client typically resumes a low-power sleep state upon entering an idle period, and it can enter this state more quickly if the performance of the system permits faster data transfer. Wi-Fi benefits The IEEE 802.11n standard primarily provides for high throughput, high-efficiency and long-range data connectivity. It also includes the use of multiple antennas and transmit-receive chains. However, IEEE 802.11n likewise features a single-stream mode intended to provide the same benefits of the standard to low-power, small form-factor devices like handheld phones. These benefits include: • Higher throughput achieved Read more online Embracing 02.n Product segments are aking advantage of the 02.n standard since it provides more reliable connections for bandwidthintensive applications. • Having efficient WiMAX, Bluetooth, WiFi in handsets • Beginner’s corner: Wireless LAN The International Conference on Next Generation Software Application (NGSA -08) aims to support multidisciplinary software research. Topics include object based storage, OFDM, distributed computing, data mining, and more. Visit event website.

REA-200 Dec. 11-13, 2008 IIT-Delhi, New Delhi WiMAX boosts India broadband market continued from page ment where the user can be both moving in a car while accessing data at high speeds, a proven, well-tested WiMAX protocol stack is important. Chipsets like Beceem BCSM250 uses a WiMAX protocol stack that has been tested both across different base station vendors as well as different conditions in the lab and field environment. This level of testing is critical for handling the demands of the end-user who will want to access broadband data in various scenarios. India is a huge market eagerly waiting for broadband access. Mass market Internet access in the country should come from an easy-to-use handheld device much like a mobile phone, and should cut across demographic and social segments. A WiMAXenabled phone will not only improve the economy and com- Renewable Energy Asia hosts a conference and exhibition related to renewable energy technologies, mitigation of green house gas emissions, and renewable energy policy, planning and education.
