QUESTION: 25

Which one of the following location tracking technologies is most energy efficient in typical implementations?

BLE Beacons
Cellular
GPS
Wi-Fi

Answer(s): A

Explanation:

BLE Beacon Power Efficiency: Bluetooth Low Energy (BLE) beacons are designed for low power consumption. Their primary function is to periodically broadcast short data packets (advertising their presence).
Other Technologies:
Cellular: More power-hungry due to long-range communication and complex protocols. GPS: Power intensive, especially when actively tracking location.

Wi-Fi:

QUESTION: 26

You are deploying a ZigBee network based on the frequency band available for ZigBee deployment worldwide.
What allowable action will do the most to minimize ZigBee and 802.11 interference?

Use the 6 GHz band for all ZigBee communications
Use the 5 GHz band for all 802.11 communications
Use the 5 GHz band for all ZigBee communications
Use the 2.4 GHz band for all 802.11 communications

Answer(s): B

Explanation:

Wi-Fi and Zigbee Interference: Both can operate in the 2.4 GHz band, leading to potential interference that degrades performance for both networks.
5 GHz Advantages:
Less crowded: Fewer devices operate in the 5 GHz band, reducing interference potential. Wider Channels: 5 GHz supports wider channels, enabling higher data throughput for Wi-Fi.

QUESTION: 27

You are planning a wireless solution deployment. The organization has several wireless solutions in use. The new deployment must coexist with these other wireless solutions.
What is the most important factor to consider when implementing the new wireless solution?

Coordinating mounting locations with the other wireless solutions
Implementing matching encryption keys synchronized with the other wireless solutions
Implementing contrasting encryption keys countering the other wireless solutions
Coordinating frequency use with the other wireless solutions

Answer(s): D

Explanation:

Coexistence Priority: Frequency coordination is the most critical aspect in ensuring that multiple wireless solutions function without significant interference. Impact of Interference: Uncoordinated frequencies lead to:
Signal degradation: Reduced network performance and reliability. Data errors and retransmissions: Inefficient operation and higher battery drain on devices.

What is the primary difference between LoRa and LoRaWAN?

LoRa is the modulation method and LoRaWAN implements the higher network layers
LoRa Is used for communicating across the Internet and LoRaWAN is used only on the local link
LoRa uses RF and LoRaWAN uses light-based communications
LoRaWAN is the Physical Layer and LoRa is the Transport Layer

Answer(s): A

Explanation:

LoRa: Refers to the physical layer chirp spread spectrum (CSS) modulation, enabling long-range, low- power communication.
LoRaWAN: An open MAC layer protocol that builds on LoRa, defining network architecture, device management, and data routing for large-scale LoRa networks.
