Question:
What are three broadband wireless technologies? (Choose three)

• WiMax
• satellite Internet
• municipal Wi-Fi
• site-to-site VPN
• DSLAM
• CMTS

Explanation: WiMAX is short for Worldwide Interoperability for Microwave Access. WiMAX is a family of wireless communication standards based on the IEEE 802.16 set of standards.

Satellite Internet provides Internet access via satellite. It is a form of wireless broadband technology. But it is usually slower than DSL and cable modem.

Municipal wireless network is a city-wide wireless network. This is usually done by providing municipal broadband via Wi-Fi to large parts or all of a municipal area by deploying a wireless mesh network. The typical deployment design uses hundreds of wireless access points deployed outdoors, often on poles.

DSLAM (Digital Subscriber Line Access Multiplexer) is a network device, usually at a telephone company central office, that receives signals from multiple customer Digital Subscriber Line (DSL) connections and puts the signals on a high-speed backbone line using multiplexing techniques. It is a cable technology, not a wireless technology.

Cable Modem Termination Systems (CMTS) is a piece of equipment, typically located in a cable company’s headend or hubsite, which is used to provide high speed data services, such as cable Internet or Voice over Internet Protocol, to cable subscribers. It is a cable technology, not a wireless technology.
