Wireless Access Point

In this work, a development of stock counting system using PDA is presented. The design and development issues are studied for the case of a superstore in Thailand. The stock counting is a tedious work in a department store. Employees need to physically walk down the shelves and count the amount of items each day. The amount of items is compared to the amount in the system to check for the loss of items every day. For a large-size department store, many employees need to spend lots of time to perform the tasks. Introducing the use of PDA together with the barcodes of the products will help automate the process, save time, and reduce the errors for checking the stock counts. In this paper, the design of system presents in the aspect of 1) the PDA software client and server sides 2) wireless access point installation costs and plans. After the development, the system is employed. Its efficiency is compared to the manual counting and the user satisfactory is evaluated.

And Control

In this paper, a novel and compact center-fed dual-band WiFi printed antenna is presented. This antenna is designed using two different arms which correspond to the oscillation points of the dual band, and uses parasitic capacitance and U-shaped microstrip line to match and control the necessary bandwidth. The measured frequency bandwidth of this antenna is 2.3–2.61 GHz (310 MHz, 12.7%) at 2 GHz, and the high-frequency bandwidth is 4.82–5.84 GHz (1020 MHz, 19.1%) at 5 GHz, which meets the requirements for applications in global WiFi communication. This PCB antenna is double-sided, long, and narrow; its size is 7 × 45.9 × 1 mm3; it can be applied to wireless access point; and it has a near-omni-directional radiation pattern. The design, analysis, and measured results of this proposed antenna will be presented.
