SCTE Broadband Wireless Specialist (BWS) Certification
Exam | Latest Verified Questions and Detailed Answers
OVERVIEW DESCRIPTION
This comprehensive set of multiple choice questions is designed for the SCTE
Broadband Wireless Specialist (BWS) certification, an entry-level credential
administered by the Society of Cable Telecommunications Engineers. It assesses
foundational knowledge across four core curriculum areas: Residential Wireless
Networks, Wi-Fi Radio Frequency (RF) Operations, Wi-Fi Installation and Security, and
Wi-Fi Network Operations. The questions cover the planning, installation, and
troubleshooting of Wi-Fi and residential wireless networks, including IEEE 802.11
standards, RF theory, antenna principles, channel planning, WPA2/WPA3 security, IP
networking essentials (IPv4/IPv6, DHCP, DNS), and common diagnostic tools.
1. Residential Wireless Networks
QUESTION 1
Which IEEE 802.11 amendment introduced Wi-Fi 6, also known as High Efficiency
Wireless?
A. 802.11ac
B. 802.11ax
C. 802.11n
D. 802.11ad
CORRECT ANSWER: B
EXPERT RATIONALE:
802.11ax is marketed as Wi-Fi 6 and focuses on efficiency in dense environments.
802.11ac is Wi-Fi 5 and 802.11n is Wi-Fi 4.

QUESTION 2
A customer wants to connect a desktop computer that has no built-in Wi-Fi to a home
wireless network. Which device should they add to the desktop?
A. Wireless range extender
B. Wireless access point
C. Wireless USB adapter
D. Ethernet switch
CORRECT ANSWER: C
EXPERT RATIONALE:
A wireless USB adapter gives a non-wireless device the ability to join a Wi-Fi network. A
range extender repeats an existing signal but does not provide a client interface for a
wired PC.
QUESTION 3
In a typical single-family home, what is the primary advantage of placing the wireless
router on the main floor rather than in the basement?
A. Shorter Ethernet cable to the modem
B. Better line-of-sight propagation and reduced signal blockage
C. Easier access for firmware updates
D. It avoids interference from water pipes only
CORRECT ANSWER: B
EXPERT RATIONALE:
Central, elevated placement minimizes the number of floors and walls the signal must
penetrate, improving coverage. Basement placement often results in severe attenuation
upward.

QUESTION 4
Which of these building materials typically causes the greatest attenuation of a 5 GHz
Wi-Fi signal?
A. Drywall
B. Plywood
C. Concrete with rebar
D. Open-cell foam insulation
CORRECT ANSWER: C
EXPERT RATIONALE:
Dense materials containing metal, such as reinforced concrete, absorb and reflect RF
energy heavily. Drywall and wood cause far less loss.
QUESTION 5
A home uses both a wireless router and a Wi-Fi range extender. The extender connects
to the router wirelessly and retransmits the signal. What is one downside of this
arrangement?
A. It eliminates the need for a guest network
B. It doubles the total available bandwidth
C. Throughput on the extender’s band may be halved
D. It converts 2.4 GHz signals to 5 GHz
CORRECT ANSWER: C
EXPERT RATIONALE:
A single-radio repeater must receive and retransmit on the same channel, effectively
cutting throughput in half. Dual-band extenders can mitigate this but the basic principle
of repeating shares airtime.

QUESTION 6
What does the “AX” in 802.11ax primarily improve compared with 802.11ac?
A. Only maximum link rate in a clean environment
B. Efficiency in high-density client scenarios using OFDMA
C. Support for 2.4 GHz band only
D. Mandatory use of 160 MHz channels
CORRECT ANSWER: B
EXPERT RATIONALE:
OFDMA allows multiple users to share a channel simultaneously in smaller resource
units, improving aggregate efficiency. 802.11ac introduced 5 GHz enhancements, while
802.11ax works in both bands.
QUESTION 7
A customer’s home office is at the far end of the house, beyond two interior walls. The
router is at the opposite end. Which solution is MOST appropriate to deliver reliable
Wi-Fi to the office?
A. Replace the router’s power adapter
B. Install a single high-gain omnidirectional antenna on the router
C. Deploy a mesh Wi-Fi system with a satellite node near the office
D. Enable WEP encryption to boost signal
CORRECT ANSWER: C
EXPERT RATIONALE:
Mesh systems use multiple nodes to blanket a home, placing a node closer to the dead
spot to overcome distance and obstructions. Encryption does not affect range.
QUESTION 8
Which Wi-Fi standard first introduced multiple-input multiple-output (MIMO)
