Abstract: This paper shows the potential system benefits of
simple tracking solar system using a stepper motor and light sensor.
This method is increasing power collection efficiency by developing
a device that tracks the sun to keep the panel at a right angle to its
rays. A solar tracking system is designed, implemented and
experimentally tested. The design details and the experimental results
are shown.
Abstract: It is important to provide possibility of so called
“handover" for the mobile subscriber from GSM network to Wi-Fi
network and back. To solve specified problem it is necessary to
estimate connection time between base station and wireless access
point. Difficulty to estimate this parameter is that it doesn-t described
in specifications of the standard and, hence, no recommended value
is given.
In this paper, the analytical model is presented that allows the
estimating connection time between base station and IEEE 802.11
access point.
