Question

True or False. Write either T or F at the right of each expression. The higher the value of signal to noise ratio (SNR), the lower is the value of the bit error rate (BER). The hidden terminal problem in Wi-Fi is mitigated by the use of CSMA/CD. In a wireless link, interference does not matter as only noise impacts the signal to noise ratio CDMA is a multiple access technique You don't need a license to install a WiFi base station Triangular routing is the most efficient way to handle mobility in cellular networks Mobile IP is not always necessary as mobility can be handled efficiently through regular routing Content distribution networks are third-party operated networks that bring content close to the user The playout delay can be adapted based on the estimated delay Pure ALOHA is more efficient than slotted ALOHA in channel utilization The job of ARP is to translate a given MAC address to IP address Ethernet and 802.11 use the same frame structure Acknowledgement is used in 802.11 but not in wired Ethernet If stored video is streamed directly from a Web server to a media player, then the application is using TCP as the underlying transport protocol When using RTP, it is possible for a sender to change encoding in the middle of a session IoT is a kind of infrastructure-based wireless network For many scenarios of IoT, communication with peers outside immediate communication range is required, and a possible solution is to use multi-hop networking The Internet of Things (IoT) is a shorthand way of describing a globally interconnected continuum of devices and objects interacting with the physical environment, people and each other If an RTP session has a separate audio and video stream for each sender, then the audio and video streams use the same SSRC Underwater networks can use radio frequency waves as long as CSMA/CA is correctly implemented.
