INTRODUCTION The rapid pace of adoption of Web-enabled mobile handsets in worldwide markets has become an increasingly important issue for information systems professionals. A recent survey indicates that the number of global mobile Internet adopt-ers is expected to reach nearly 600 million by 2008 (Ipsos-Insight, 2004; Probe Group, 2004), while the number of Internet-connected mobile phones wi...

Unseen handset mismatch is the major source of performance degradation for speaker recognition in telecommunication environment since handset distortions are tightly coupled with speaker characteristics. In this paper, a soft-decision unseen handset characteristics estimation method based on a priori knowledge interpolation is proposed to decouple the characteristics of the unseen handset and s...

In this paper, a planar antenna for Long Term Evolution (LTE) bands and Wireless Local Area Network (WLAN) is proposed. The based on coupled-fed monopole with distributed inductor direct-fed monopole. These three components form two of operations namely low operating band from 0.59 to 0.635 GHz high 1.67 2.80 GHz. satisfy the WMTS 610, UMTS 1700, GSM 1800, LTE 1900, 2100, WLAN 2400, 2600 3600 a...

Location Based Services are a key driver in today's telecom market, even if the power of Location Based Services is not nearly exhausted in nowadays telecom systems. To build intuitive Location Based Services for mobile handsets one success factor is to cover a broad range of mobile handsets available on the market and to make the services context aware. Within the EUREKA project MyMobileWeb we...

Traditionally, for tactical Command & Control (C2), the Marine Corps utilized strictly voice communications as a result of continued reliability, modern innovative technology vulnerabilities, and the lack of ubiquitous data connectivity. Recently, driven by the technology advances there has been a shift in the paradigm toward more utilization of data applications, such as tactical chat and Blue...
