# Setup RTK solution using a local network
**This step-by-step tutorial will let you to use a RTK Rover using a GNSS Base over a Local Network, thus without any telemetry kit.**
Requirements :
1. Two computers : PC1 acting as a Base / PC2 acting as a rover
2. Two F9P devices connected to both PC : One configured as Base, the other one as a Rover. See here for procedure :
3. Both computers are connected to the same local network
**STEP 1 : Check what is the IP address on Base computer PC1**
Press Windows + R key touch to open
Then type in “cmd”, then click “OK” :
A new command prompt window opens. Type in “**ipconfig**”, then press **Enter**. Go down to “**IPV4 address**” and write down somewhere the IP address displayed. For instance, the one on DROTEK computer is 192.168.1.103
{% hint style="info" %}
This address is needed for a later step. Keep it in mind.
{% endhint %}
NOTE : bear in mind that IP addresses are for example purposes, replace the ones below with your own).
**STEP 2 : Configuring the Base as an NTRIP Caster.**
The base connected to the local network will be able to broadcast RTCM data to any rover that is connected to the same local network.
To do so, open **u-center software on PC1** **- Base**, then click on “**Receiver**” then “**NTRIP Server/Caster**…”.
A new window opens. Next go to “**More” tab** then configure the base caster as shown in the picture below.
Then click **OK**.
{% hint style="success" %}
The base caster is now working perfectly !
{% endhint %}
**STEP 3 : Configuring the Rover as an NTRIP client.**
The base is now continuously sending out RTCM data on the local network. You need to configure any rover to be able to gather these data to get a fixed and accurate positioning.
To do so, open **u-center software on PC2 - Rover,** then click on “**Receiver**” then “**NTRIP Client**…”.
Once again, a new windows opens. Then type in the base IP address we got from STEP 1. Next you need to type in the **SAME NAME** and **PASSWORD** that was set previously on the base during **STEP 3**.
Now click on the “**Update source table**” button located below.
Your base must be retrieved under the “**NTRIP mount point**” textbox.
Finally, click **OK**.
{% hint style="success" %}
Your base and rover are now correctly connected to each other. The rover is starting receiveing RTCM data and will shortly get a fixed position.
