In this paper, we propose a novel on-glass multi-band antenna with a planar inverter F structure for the GPS and WLAN wireless communication. A prototype of the proposed antenna with a compact size of 6mm¡Ñ25mm is experimented in the mobile handset design. The antenna shows operating bandwidths (referenced Return loss-6dB) for covering the GPS in 1.575GHz and WLAN in 2.45GHz. The present design mainly...
Built in Bluetooth wireless transmission allows easy GPS sensitivity record on the go without the hassle of external USB connections and wire cable anytime, anywhere. The mobile phone under test of far-field range testing has been the plan at the Cellular Telecommunications & Internet Association (CTIA) certification program test requirements for performing receiver performance measurement.
In this study, a novel location-based service which fulfills the Pac-Man game by retrieving the users' location information with GPS equipments in a natural campus environment is proposed. We design an integrated communication architecture of the client (PDA) and the server (Web server), and transform the GPS position information into the corresponding coordinates on campus e-map to implement this...
We build a Student-Partner mobile English learning system. We go deep into the campus to do English learning by portable of the mobile. The system offer the GPS function, campus map, camera, messaging, tracking and recording. Students can post the message or add the multimedia which he explore to the device. In the mobile, user can off-line to post the message. In addition, we design two activities,...
