# Deployer Nodes

Karrier One Cellular radios are part of the **Deployer Node layer** in the Karrier One architecture. They are responsible for:

* **Creating base mobile infrastructure**
* **Broadcasting telecom services directly to end-users**
* **Providing data to the network core for usage tracking and billing**
* **Supporting roaming users via KNS and smart contract logic**

Unlike WiFi hotspots, these radios are **primary access points**—meaning any user accessing Karrier One's telecom layer must connect through a Cellular radio first.
