Using a mobile handset in noisy environments makes the far-end speech difficult to be perceived from the near-end user perspective. As he is surrounded by a loud background noise, handset user needs to be highly concentrated to understand the far-end speaker conversation. Ambient noise reduction algorithms provide an efficient solution to build a silent zone between the handset loudspeaker and ...

This paper presents effect of delay waves on MIMO over-the-air (OTA) throughput of a handset MIMO array using a spatial fading emulator. The emulator has a number of antenna probes located on a circle around a handset under test to representing a multipath radio environment applicable to the OTA evaluation for a handset MIMO antenna. The MIMO OTA tests with and without delay waves, which have a...

In forensics, mobile phones or handsets store potentially valuable information such as Contact lists, SMS Messages, or possibly emails and Calendar appointments. However, navigating to this content on non-English configured handsets, when the operator is untrained in the language, becomes a difficult task. We discuss a feasibility study that explored the performance of optical character recogni...

A two-element phased antenna array for a mobile handset is investigated using the Finite Difference Time Domain (FDTD) method. The array is designed to provide a spatial null in the near field zone in the direction of the human head. The optimisation algorithm to obtain the minimum peak specific absorption rate (SAR) is addressed. The dynamic range of the feeding voltages in relation to the red...

A compact multiband handset antenna including MIMO antenna operation for LTE 13 band (746 ∼ 787MHz) applications is proposed. The proposed antennas are separately located on the top and bottom portions of a mobile handset in order to use the antenna area more effectively. The proposed antenna achieves isolations of higher than 14 dB, enveloped correlation coefficients (ECC) of less than 0.25, a...

Regulators need accurate data on service usage in addition to general information on markets and technology. This study presents a new type of tool, handset-based monitoring, for collecting and analyzing detailed data on usage patterns of mobile subscribers. Results of a panel organized in Finland are described and mapped to the relevant regulatory issues. Observations indicate that Finnish sub...

The mean effective gain (MEG) is an attractive performance measure of mobile handsets, since it incorporates both directional and polarization properties of the handset and environment. In this work the MEG is computed from measured spherical radiation patterns of five different mobile handsets, both in free space and including a human head & shoulder phantom. Different models of the environmen...

The main aim of this research paper is to find customers satisfactions with relations to some variables like individual features, price, brand name etc. In this study researcher has focused on the customer of Bhavnagar city and research is carried out by primary data analysis tools like Correlation, study indicates an average satisfactions of customers toward MOBILE HANDSET USERS OF SAMSUNG.

Mobile phone handsets have introduced new possibilities for musical interaction between multiple performers, as we reported in previous papers. Wireless communication between handsets now extends these possibilities even further. This paper describes development and implementation of a new performance scenario that involves remote instrument control using a Bluetooth connection. The paper propo...
