Wireless Transceiver: A transceiver is a combination of a transmitter and receiver used for wireless communication.

Radio: The radio is the primary component responsible for:

Modulation: Encoding data onto a carrier wave.

Demodulation: Extracting data from a received signal.

Transmission/Reception: Handling the actual sending and receiving of modulated signals over the air.

Automation for Consistency: Scripts eliminate the potential for human error during repetitive configuration tasks on multiple devices. This ensures uniformity across the wireless solution.

Speed and Efficiency: Scripts can be much faster than manual configuration, particularly in large deployments.

Other Benefits: While scripts might aid signal strength (e.g., optimizing settings) or enhance solution capabilities, their core value in configuration is reducing errors.

Ongoing Monitoring for Adaptability: Wireless networks are dynamic environments. Ongoing monitoring is essential because:

Changing Usage Patterns: User numbers and how they utilize the network evolve over time.

Capacity Adjustments: Monitoring reveals if the network needs scaling for more devices or changing use cases.

Security: Helps detect unauthorized access or anomalies.

Captive Portals for Guest Access: These are web pages that intercept users' requests before granting full internet access. They often require agreeing to terms, entering basic information, or viewing ads.

Hospitality Fit: Captive portals are simple to deploy, require minimal user setup, and provide control for the hospitality provider (e.g., usage limits).

Why Other Options Are Less Common:

NTLM: Microsoft authentication, mainly for corporate networks, too complex for casual guest use.

Kerberos: Complex authentication for enterprise, overkill for guest Wi-Fi

SIM Cards: Used in cellular devices, not for general Wi-Fi access.
