User’s Manual Wireless Module - Android
1. Introduction
This Wireless Module - Android is used with HungWai LCD Advertising Media Player and
Advertising Set-Top-Box. It’s easy to use and easy to setup. This Wireless adapter is an
ideal access solution for wireless Internet connection and wireless transmission.
Atypical Internet access application for the Wireless Module - Android is shown as the
following figure:
There are two different ways to access Internet:
1. With a Wireless Module - Android, 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 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.
Or package in a PE bag as an accessory with the Media player package

3. Security
Because wireless networks rely on radio signals to transmit data, they are not as secure
as wire network. 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.
