User's Manual
54M/150M/300Mbps USB WIRELESS ADAPTER User’s Manual Version 2.0 User’s Manual Wireless USB Adapter 1. Introduction Thank you for purchasing the IEEE 802.11b/g or 802.11n Wireless USB Adapter. This Wireless Adapter is easy to use and easy to setup. If you have been tired of dealing with all those messy wires to connect a laptop or PC to office or home network, this Wireless adapter is an ideal access solution for wireless Internet connection. A typical Internet access application for the USB wireless adapter is shown as the following figure: There are two different ways to access Internet: 1. With a wireless adaptor, receiving and transferring signal via a wireless router, then passed to an ADSL modem, then to local ISP (Internet service supplier) through a telephone line. 2. With a wireless adaptor, receiving and transferring signal via local AP (Access Point) or so called Hotpoint directly. Tips: An 802.11 LAN is based on a cellular architecture where the system is subdivided into cells, where each cell (called Basic Service Set or BSS) is controlled by a Base Station (called Access Point, or in short AP). 2. Package Contents: One 54 Mbps 802.11b/g or 150Mbps or 300Mbps 802.11n USB Wireless Adapter. Adapter Installation disc. User’s Manual. Antenna (optional) Warranty The warrants for the end user (“Customer”) that this hardware product will be free from defects in workmanship and materials, under normal use and service, for twelve (12) months from the date of purchase from its authorized reseller.

Email: [email protected] Received: 15 January 2021; Accepted: 17 February 2021 Abstract: Wireless sensor network (WSN) is considered as the fastest growing technology pattern in recent years because of its applicability in var- ied domains. Many sensor nodes with different sensing functionalities are deployed in the monitoring area to collect suitable data and transmit it to the gateway. Ensuring communications in heterogeneous WSNs, is a critical issue that needs to be studied. In this research paper, we study the system performance of a heterogeneous WSN using LoRa–Zigbee hybrid communi- cation. Specifically, two Zigbee sensor clusters and two LoRa sensor clusters are used and combined with two Zigbee-to-LoRa converters to communicate in a network managed by a LoRa gateway. The overall system integrates many different sensors in terms of types, communication protocols, and accuracy, which can be used in many applications in realistic environments such as on land, under water, or in the air. In addition to this, a synchronous man- agement software on ThingSpeak Web server and Blynk app is designed. -
