Module 3: Wireless and mobile networks Flashcards
What term is used to describe connecting a mobile device to another mobile device or computer to share a network connection?
Pairing describes connecting two devices using Bluetooth. Syncing Is the term used to describe synchronizing emails and calendars across a number of devices.
Which wireless technology uses a device-pairing process to communicate and operates over short distances of 100 meters?
Wireless networks can be broadly classified as follows:
Wireless wide-area network (WWAN) – It operates in the range of miles.
Wi-Fi – It operates up to distances of 0.18 miles and provides network access to home and corporate users and can include data, voice and video traffic.
Bluetooth – It uses a device-pairing process to communicate over distances of up to 0.05 miles.
GPS - It uses satellites to transmit signals that cover the globe.
What technology enables a cell phone to be used as a hands-free device?
Bluetooth provides a way to connect wireless devices, such as headsets, to a nearby mobile device. Wi-Fi and 4G provide WAN access to voice and data. NFC is used for touchless payment systems.
A student purchased a new Wi-Fi-enabled tablet computer. What is required to connect this device to the internet?
To access the internet using WiFi the tablet will need to access a wireless LAN.
Which technology allows a mobile device to establish wireless communication with another mobile device by touching them together?
Near field communication, or NFC, is commonly used to establish radio communication between two devices by placing them next to each other or by touching them together.
Which technology will allow a mobile device to share an internet connection with other devices via tethering?
Tethering is commonly done over Bluetooth or a USB cable. A mobile hotspot is another form of internet sharing and is provided over Wi-Fi.
What are two methods typically used on a mobile device to provide internet connectivity?
Mobile devices commonly use Wi-Fi and cellular to connect to the internet. The cellular connection uses the cellular data network for a fee. The Wi-Fi connection uses an 802.11 wireless network in the area to connect to the internet.
Which wireless technology allows a customer to connect to a payment system with a smartphone?
NFC, or Near Field Communications, is a wireless technology for communication between devices at extremenly short distances and is used in contactless payment systems.
A salesperson is using a smartphone map application to locate a business. What wireless technology enables the smartphone to receive satellite geolocation information for the map application?
GPS, or Global Positioning System, provides the geolocation services used by smartphones to calculate the position of the phone.
What two pieces of information are required when manually connecting either an iOS device or an Android device to a secured wireless network?
In order to connect an Android or iOS device to a Wi-Fi network manually the SSID and the password are required to connect.
Which wireless technology can be used to connect wireless headphones to a computer?
Bluetooth is a low-power, short range wireless technology that provides connectivity for accessories such as speakers, headphones, and microphones.
