Recommended Specifications
| Recommended Specifications | Notes | |
|---|---|---|
| Wi-Fi Standard | Wi-Fi 6E (802.11ax) | Minimum Wi-Fi 5 or higher recommended In certain countries, the use of 6GHz devices may be restricted due to local regulations, and in such cases, the device will operate on the 5GHz band. |
| Frequency Band | 5 GHz, 6 GHz | The 2.4 GHz band is unsuitable for scan data transmission due to heavy interference |
| Channel Width | 5 GHz: 80 MHz 6 GHz: 160 MHz | If the channel bandwidth is narrow (20 MHz or 40 MHz), data transmission becomes slower, which may lead to signal latency or disconnection. |
| Wireless Signal Strength | Above -60 dBm (The closer to 0, the stronger the signal. Example: -50 dBm is stronger than -60 dBm) | Weak signals may cause disconnection/latency. |
| Security Protocol | WPA3SAE + AES Only Personal (WPA2/WPA3-Personal) Wi-Fi is supported. | Encryption methods to secure Wi-Fi. WPA3 is the most secure, and WPA2 is also generally available. If your hospital/clinic uses enterprise Wi-Fi, a separate personal Wi-Fi environment is required. |
| Wi-Fi Password Setting | Must be set (Open networks not allowed) | A Wi-Fi network password must be set for proper connection. Public Wi-Fi without a password (Open Wi-Fi) is not supported for security reasons. |
| Captive Portal | Must be disabled | Public Wi-Fi login pages (hotels, cafés, etc.) may cause unstable connections. |
ℹ️ Note
If you have an extra wireless device (Access Point) separate from the main router (Typically a device on the ceiling or wall dedicated to Wi-Fi)
Two intraoral scanners can be used at the same time.
If you only use a single standard wireless router
One scanner is recommended: Since the bandwidth is shared with other devices, using two scanners simultaneously may cause connection drops or slow performance.
If multiple devices such as smartphones and computers are connected to the same router, the scan data transfer speed may slow down. For stable scanning, it is recommended to use a dedicated router for the scanner whenever possible. Stable scanning depends more on router performance than on internet speed.
How to Check Wi-Fi Router Specifications / Security Protocol
- Check the router label: The model name and Wi-Fi standard (Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, AX1800, etc.) are usually indicated. If only the model number is shown, check the full specifications online.
- Check on PC or Mac: You can verify the protocol in the Wi-Fi connection properties.
[Windows PC]
Settings → Network & Internet → Wi-Fi → Connected Network → Check “Protocol” (e.g., 802.11ac = Wi-Fi 5, 802.11ax = Wi-Fi 6)
Also check the security protocol listed below the protocol.
[Mac]
Hold the Option (⌥) key and click the Wi-Fi icon in the top menu → Check the frequency band (2.4 GHz / 5 GHz / 6 GHz) and the security protocol.
Wi-Fi Router Installation Guide
1. Preparing the Router
Check the provided recommended network specifications and select a router that meets the conditions.
i900 Mobility can only connect and scan in the 5 GHz or 6 GHz band.
Therefore, it is recommended to use a product that supports Wi-Fi 6E.
2. Selecting the Router Installation Location
<Open Space>
When using 1 scanner: within 30 m from the workspace
When using 2 scanners: within 24 m
<Space with walls or obstacles> Install the router as close as possible to the scanner to minimize the impact of walls, doors, metal structures, and coated glass.
3. Connecting Router Power and Network
The user connects to Wi-Fi in the 5 GHz or 6 GHz band from PC or iPad and checks that internet access is working properly. This is a basic procedure to ensure that the router is operating normally and the network connection is stable.
Check that the Wi-Fi signal strength (RSSI) is above -60 dBm.
Windows PC: Check by entering the command netsh wlan show interfaces in CMD
MacOS: Press Option + Wi-Fi icon simultaneously to display RSSI information
⚠️ Caution
If your router has Smart Connect or Band Steering, please disable these features.
If either feature is enabled, the device may automatically connect to the 2.4 GHz Wi-Fi network during the connection process.
If different frequency bands use the same network name (SSID), it may cause connection issues. Please assign a unique network name to each band.
Example: TP-Kink_E3EB, TP-Kink_E3EB_5G, TP-Kink_E3EB_6G
4. Checking Router Settings
If necessary, check and configure the following items in the router settings page.
- Set Wi-Fi password
- Select supported security protocol
- Enable mDNS function
- Disable Captive Portal
To access the settings page of each router, search for the router model name on the internet.
Dedicated Network Setup Guide
If your i900 Mobility connection is unstable, we recommend setting up a dedicated network using a new router that is separate from your existing clinic network.
Configure the new router in Router Mode (not AP Mode), and connect the LAN port of your existing main router to the WAN port of the new router using an Ethernet cable.
With this configuration, the new router uses its own DHCP server and IP address range, creating a dedicated network exclusively for i900 Mobility that is isolated from your existing clinic network. Connect the PC or iPad used for scanning to this dedicated network provided by the new router.
⚠️ Caution
1. The IP address of the new router must be configured so that it does not overlap with the IP address range of the main router (the existing clinic network). In a typical network environment, you can usually avoid overlap by changing only the third number in the IP address.
- Main router:
192.168.0.1 - New router:
192.168.10.1
You can check the IP address of the network currently connected to your computer as follows.
1) Open Command Prompt: Press Win + R, enter cmd, and press Enter.
2) Enter the command: Type ipconfig and press Enter.
3) Check the IP address: The number shown under IPv4 Address in the results (for example, 192.168.x.x) is your computer’s IP address.
Check the IP address of the main router before proceeding with the configuration.
2. If your router allows you to configure the channel width manually, use the following settings.
- 80 MHz: Minimum recommended
- 160 MHz: Recommended
- 20 MHz, 40 MHz, 320 MHz: Connection not supported
The channel used by the new router should also be configured to minimize interference with the main router whenever possible.
To help select an appropriate channel, use any of the following features if they are available on your router.
- Wi-Fi Analyzer
- Site Survey
- Channel Scan
- Nearby Wi-Fi Scan
- Channel Utilization
- Automatic Channel Optimization
