Wireless Specialist

Explore wifi antennas from omnidirectional to highly directional, covering radiation patterns, passive gain, and IRP calculations for 2.4/5 GHz indoor and outdoor deployments, including internal and external antennas.

Explore how IEEE 802.11 wireless standards evolve through drafts and amendments. Learn how bands like 2.4 GHz, 5 GHz, 6 GHz, and 60 GHz enable different Wi-Fi capabilities.

Explore 802.11 physical layers from direct sequence spread spectrum to high efficiency, covering ofdm, channel widths up to 160 mhz, mimo, and six gigahertz bands.

Explore key 802.11 non-physical amendments, including 802.11i 2004 with WPA/WPA2, 802.11e 2005 for quality of service, 802.11k 2008 for resource management, roaming security, and 802.11w 2009 with management frame protection.

Define 802.11 terminology: basic service set (BSS), service set identifier (SSID), extended service set (ESS), and independent basic service set (IBSS) with access points and ad hoc networks.

Design a reliable wireless LAN by optimizing coverage and capacity through site surveys, RF behavior, and application requirements like throughput, latency, and jitter.

Explore popular wireless feature requirements such as band steering, load balancing, auto channel selection, and network monitoring. Understand how these features impact performance and coverage.

Learn to configure and implement a wireless LAN by selecting a familiar vendor, ensuring capacity and coverage, and optimizing access point placement and channels through planning, simulation, and frequency usage.

Learn about channels on 2.4, 5, and six gigahertz, including non overlapping 2.4 gigahertz channels 1, 6, 11; 20–160 megahertz widths and DFS radar detection to avoid interference.

Secure the wireless network with WPA2, CCM and GCM encryption, avoid WEP and TKIP, and use MAC filtering, hidden SSID, and client isolation against social engineering.

Secure wireless access by applying authentication, authorization, and accounting with radius and EAP, while enforcing confidentiality, integrity, availability, and robust key management with symmetric and asymmetric encryption.

Explore bring your own device (BYOD) risks and security controls, including network access control, device quarantine, and containerized data in MDM environments for enterprise networks.

Explore how the MDM server registers, manages, and decommissions devices, deploys profiles for VPN, email, and Wi-Fi, and enables over-the-air updates and device wipe.

Explain how to provide guest access to visitors by separating the guest wireless network from the main network, using separate SSIDs, passwords, captive portals, VLANs, and firewalling.

Enable quality of service on access points and stations to prioritize delay-sensitive traffic like VoIP through priority wait times, and explain dynamic rate switching and backward compatibility across same-frequency networks.

Explore how wireless chains on a dual-antenna radio enable SISO and MIMO, including mu-mimo vs mimo, to boost throughput in 802.11n/ac networks.

Explore how wireless csma/ca uses rts/cts and cts-to-self to mitigate hidden node collisions, tune hardware protection threshold, and employ adaptive noise immunity for improved Mikrotik point-to-point links.

Explains guard interval in 802.11ac, multipath and intersymbol interference, and shows how 800 ns vs 400 ns settings on Mikrotik routers affect throughput.

Discover the access point's role in a wireless LAN, compare indoor and outdoor models, and analyze two vendor specs— Ubiquiti and Mikrotik— for bands, frequencies, antenna gain, and PoE power.

Configure access points by choosing band, power, and security, via autonomous or controller-based methods. Explore cloud and local management, centralized versus distributed forwarding, and vendor options like Ubiquiti and Mikrotik.

Classify client device types in wireless networks—mobile phones, tablets, laptops, desktops, and special devices—and explain security capabilities, band support, streams, and protocols such as Peap, Eap-tls, and WPA, WPA2, WPA3.

Identify physical layers supported on client devices and verify 2.4 ghz coverage (802.11b/dss) and 5 ghz channels (erp, ht) plus six ghz compatibility; check channels before buying.

Identify which security protocols end devices support, compare WPA and WPA2, EAP methods with radius server and certificates, and evaluate applications in use by latency, throughput, ports, and user load.

Explore common vertical markets for wireless LAN deployment, and learn about office, hospital, hospitality, education, and retail considerations, including security with captive portals, WPA, and PCI DSS.

Analyze industrial, emergency response, temporary deployments, small office home office, and public Wi-Fi markets; deploy low-power access points with overlapping cells, perform site surveys, and ensure captive portal authentication.
