Spectrum Scan Best Practice
- TVWS is an unlicensed spectrum band, so scanning the spectrum to understand the quality of the channels is the most important step before connecting the CPEs.
- Scan the spectrum for 24 hours.
- After watching the above videos and becoming a WiFrost Cloud NMS expert, :), on the Base Station dashboard page, go to the “Channel Scan” page.
- Hit “Start Scanning” and confirm in the next dialogue box
- After the scan runs for 12 to 24 hours, come to the same/above location and hit “Stop Scan” to get the Base Station back in Transmit mode.
- Select the cleanest available channels.
Three steps for a successful TVWS connection setup:
-
Connect wEPC eth0 port to the ISP Internet Router
-
Base Station
1. Connect Base Station and Base Station antenna
2. Power up Base Station and connect to the wEPC eth1. Directly wire connection is recommended. A switch can be used to connect the Base to the wEPC as well, if direct connection is not possible. -
CPE
1. Power up CPE and point towards the Base Station (point away if close than 100 ft to prevent too strong of a signal for indoor/lab testing)
2. Plug in Wi-Fi Router
3. LED Indicator LED Indicator| Functions| Description
---|---|---
Power| Power indicator| Green Light – Device is powered on and booting,
SYS| System indicator| Orange Color – Device is powered on and booting, Green Color —Network is available.
Lit| Wireless signal indicator| OFF – No wireless connection is established
RF1:-115dBm a RSRP < -110dBm
RF2:-110dBm a RSRP < -105dBm
RF3:-105dBm a RSRP < -97dBm
RF4:-97dBm <= RSRP
SIM| WAN Indicator| Blinking Green – SIM card is error. Solid Green -SIM card is ready.
ETH| LAN port status Indicator| OFF – No LAN cable connected
Solid Green – The LAN port is up
Blinking Green – LAN data transmission in progress

Click on Details to go to the Base Station page
1. list of device action: reboot, start/stop transmit, turn on/off scan, enable/disable GPS, switch EPC mode
3. Click “Scan Mode” to collect spectrum scan data
1. after scan mode turned on, “Device Status” in the to pane will change from “Transmitting” to “Scanning”. Scan interval is 7 min
2. Let the radio run in scan mode for 1 hr to up to 24 hours initially to collect good spectrum scan data. If scan is stopped, or devices reboots, the scan mode need to be started again. Please wait 15 mins to start new scan period. -
After spectrum scan is done, a channel graph like below will show the channel noise
-
Go to the Channel Selection page, and select one of more channels that are clean, e.g. Ch 25, 26 , 37 and 38 appear to be the cleanest in the above screenshot. (your exact channels quality and availability will differ).
1. After hitting transmit, the Base will reboot and start transmitting on the set channel(s)
2. Base reboot time is between 4-6 minutes
3. The CPE will connect to the Base Station in 3 to 4 minutes after Base starts to transmit -
Check CPE light
1. only one flashing green light means CPE is looking for a base to connect
2. four solid green light means CPE connected to the Base -
Connect a PC to the Wi-Fi router or directly to the CPE to check Internet Connectivity
Firmware Upgrade
