Broadband Wireless Technologies

ABC

The three broadband wireless technologies are:

1. WiMax (Worldwide Interoperability for Microwave Access): It is a wireless broadband technology that offers high-speed internet access over long distances. It uses microwave frequencies to transmit data and can provide connectivity to devices within a range of several kilometers. WiMax can be used for a variety of applications such as last-mile internet access, mobile broadband, and backhaul for cellular networks.

2. Satellite Internet: It is a wireless technology that provides internet access via communication satellites. The technology works by transmitting signals from a user's satellite dish to a satellite in geostationary orbit, which then relays the signal to a ground station. Satellite internet is typically used in rural or remote areas where traditional wired or wireless broadband options are not available.

3. Municipal Wi-Fi: It is a wireless broadband technology that offers internet access in public areas such as parks, squares, and streets. Municipal Wi-Fi networks are typically deployed by local governments to provide free or low-cost internet access to residents and visitors. The technology uses wireless access points that are strategically placed throughout the city to create a network that covers a large area.

The other options mentioned in the question are not broadband wireless technologies:

• Site-to-site VPN (Virtual Private Network) is a technology that creates a secure tunnel between two networks over the internet.

• DSLAM (Digital Subscriber Line Access Multiplexer) is a device used to connect multiple DSL subscribers to a single internet service provider.

• CMTS (Cable Modem Termination System) is a device used to provide high-speed internet access over cable TV networks.
