CWT-101 is CWNP's hands-on technician certification covering basic RF, 802.11 features, WLAN hardware, AP installation, and troubleshooting. The exam has 60 questions in 90 minutes, requires 70% to pass, and costs $174.99 through Pearson VUE. CWT is vendor-neutral and ideal for field technicians who install APs, run cabling/PoE, and apply configuration templates from a controller or cloud dashboard. It pairs well with CWS for sales and is a strong precursor to CWNA for those moving into wireless administration.

1What unit expresses absolute RF power in wireless networking?

A.dBi

B.dBm

C.dB

D.dBd

Explanation: dBm expresses absolute power referenced to 1 milliwatt, where 0 dBm = 1 mW. Field technicians read dBm on signal meters to verify AP transmit settings and client RSSI. dBi and dBd describe antenna gain, and dB alone is a relative ratio with no absolute reference.

2Which frequency band is used by 802.11b/g/n in addition to 5 GHz dual-band radios?

A.900 MHz

B.2.4 GHz

C.6 GHz

D.60 GHz

Explanation: The 2.4 GHz ISM band is shared by 802.11b, 802.11g, and 2.4 GHz radios of 802.11n/ax. Technicians installing APs must remember 2.4 GHz has only three non-overlapping 20 MHz channels (1, 6, 11 in North America) and is heavily congested.

3What does an omnidirectional antenna's radiation pattern look like in the horizontal plane?

A.A narrow forward beam

B.A 360-degree circular pattern

C.A figure-eight pattern

D.A pencil beam

Explanation: An omnidirectional antenna radiates equally in all 360 degrees in the azimuth plane, producing a donut-shaped pattern with a null directly above and below. Most ceiling-mounted indoor APs ship with omni antennas and should be installed in the middle of the coverage area, not against a wall.

4What does PoE stand for in the context of access point installation?

A.Power on Ethernet

B.Power over Ethernet

C.Packet over Ethernet

D.Port on Ethernet

Explanation: Power over Ethernet (PoE) delivers DC power and data over the same Ethernet cable to APs, IP cameras, and phones. Field technicians use PoE so APs can be installed in ceilings without nearby AC outlets. Standards include 802.3af (15.4 W), 802.3at (30 W), and 802.3bt (60-100 W).

5Which IEEE standard defines wireless LANs commonly known as Wi-Fi?

A.802.3

B.802.11

C.802.15

D.802.16

Explanation: The IEEE 802.11 family of standards defines wireless LAN operation for what consumers call Wi-Fi. 802.3 is wired Ethernet, 802.15 covers Bluetooth and Zigbee, and 802.16 is WiMAX. CWT technicians install equipment that complies with various 802.11 amendments such as 802.11ac and 802.11ax.

6What is the network name that wireless clients use to identify a WLAN?

A.BSSID

B.SSID

C.MAC address

D.VLAN ID

Explanation: The SSID (Service Set Identifier) is the human-readable name of a wireless network broadcast in beacon frames. The BSSID is the radio's MAC address that uniquely identifies a single AP radio. Technicians configure SSIDs when applying templates from a controller or cloud dashboard.

7Which device centrally manages multiple lightweight access points in an enterprise WLAN?

A.Wireless LAN controller (WLC)

B.Layer 2 switch

C.Network firewall

D.DHCP server

Explanation: A wireless LAN controller (WLC) centrally configures, monitors, and updates lightweight or controller-based access points. Technicians often connect new APs to a PoE switch port and let them auto-discover the WLC by DHCP option, DNS, or static configuration.

8What category of Ethernet cable is the practical minimum for a Gigabit AP uplink with PoE?

A.Cat3

B.Cat5

C.Cat5e

D.Coaxial

Explanation: Cat5e is the practical minimum for 1 Gbps Ethernet uplinks delivering PoE to modern APs; Cat6 or Cat6A is preferred for 2.5/5/10 GbE uplinks on Wi-Fi 6/6E APs. Cat5 is rated only for 100 Mbps and Cat3 for legacy voice. Coaxial is not used for Ethernet runs.

9Which of the following is a typical maximum Ethernet cable run length per TIA/EIA-568?

A.50 meters

B.75 meters

C.100 meters

D.250 meters

Explanation: TIA/EIA-568 specifies a maximum horizontal run of 100 meters (90 m of permanent cable plus 10 m of patch cords) for twisted-pair Ethernet. Technicians installing APs in large buildings must plan IDF/MDF placement so no AP cable run exceeds 100 m, or add a powered repeater or fiber.

10What does RSSI measure?

A.Received signal strength

B.Signal-to-noise ratio

C.Modulation index

D.Channel utilization

Explanation: RSSI (Received Signal Strength Indicator) is a measure of how strong the received RF signal is at the radio, usually displayed in dBm. Technicians use RSSI on smartphone Wi-Fi tools or AP dashboards to validate coverage matches the design after mounting APs.

About the CWT Exam

The Certified Wireless Technician (CWT-101) is CWNP's entry-level technician certification. CWT validates the practical skills needed to install access points from a design document, run cabling, deliver Power over Ethernet (PoE), apply configuration from a controller or cloud dashboard, and perform basic Wi-Fi troubleshooting. It is vendor-neutral and aimed at field technicians and installation crews.

2Memorize PoE classes (802.3af 15.4 W, 802.3at 30 W, 802.3bt 60-100 W) and which AP models need each

3Know the difference between SSID, BSSID, and ESSID, and how an AP advertises them in beacons

4Practice quick EIRP math (Tx power + antenna gain - cable loss) using the rule of 10s and 3s

5Understand cabling rules: 100 m run length, plenum vs riser ratings, and Cat5e/Cat6/Cat6A choices for PoE+ and PoE++

Frequently Asked Questions

What is the CWT-101 exam?

CWT-101 is the Certified Wireless Technician exam from CWNP. It validates the practical skills field technicians need to install access points, run cabling, deliver PoE, apply configuration from a controller or cloud dashboard, and perform basic Wi-Fi troubleshooting. The exam has 60 multiple-choice questions in 90 minutes and requires 70% to pass.

How is CWT different from CWNA or CWS?

CWT (Certified Wireless Technician) is hands-on and focused on installing and supporting wireless equipment in the field. CWNA (Certified Wireless Network Administrator) is administrator-level and digs into RF math, WLAN design, security, and protocol details. CWS (Certified Wireless Specialist) is sales-oriented. Many WLAN field engineers pair CWT with CWS, then progress to CWNA.

What jobs can I get with the CWT certification?

CWT supports roles including Wireless Installation Technician ($45-70K), WLAN Field Engineer ($55-80K), Low-Voltage / Structured Cabling Technician with wireless focus, and IT Support Technician for SMBs deploying Meraki, Aruba Instant On, or similar cloud-managed WLANs. CWT is recognized as a vendor-neutral signal that you can install APs correctly the first time.

Is CWT worth taking in 2026?

Yes — Wi-Fi 6/6E and Wi-Fi 7 rollouts continue to drive demand for technicians who can mount APs, run Cat6A, deliver 802.3bt PoE, and apply controller or cloud templates. CWT formalizes those field skills with a vendor-neutral credential and serves as an inexpensive on-ramp to CWNA.

How long does it take to prepare for CWT-101?

Most candidates pass with 30-50 hours of study over 4-6 weeks, especially those already doing low-voltage cabling or basic IT support. Hands-on time with a real AP (cloud-managed or controller-based) and a PoE switch dramatically shortens the learning curve compared to studying with text alone.
