With a wireless adapter, 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). The WLAN ( Wireless Local Area Network) normally means the WiFi local network. 2. Package Contents 1pc Wireless Module - Android. Insert in the USB port of the Media player.

Wireless networks are susceptible to viruses and breaches like eavesdropping and need to be protected in order to be secure. There are many security measures to safeguard wireless networks, protect the data, and keep unauthorized users out. Hotspots, on the other hand, are often free of standard security practices in an effort to make it easy for anyone to connect. It may be found that some pay hotspots administered by service providers offer have some level of security, however, when using a hotspot, it’s always a good idea to be proactive and to employ security measures of your own. 4. Key terms Wi-Fi: short for “wireless fidelity”, a generic label that refers to wireless networks or networking. Hotspot: a specific geographic location in which an access point provides public wireless broadband network services to mobile visitors through a WLAN. Throughput: the amount of data transmitted in a set amount of time. Bandwidth: the amount of data that can be carried from one point to another in a given time period (usually a second). Chipset: a group of microchips that execute various functions (like memory) to support the CPU. 5.
