RDK Connectivity provides a common software and data solution across all Connectivity access technologies including Fixed Wireless, DOCSIS, GPON, and DSL. It provides functionality such as routing, Wi-Fi, DNS, remote management, and the smaller image footprint eases deployment on devices.

Some of the key characteristics of RDK-Connectivity are:

**Open-Source Platform:** RDK-Connectivity is developed as an open-source project under RDK Management LLC.

**Modular & Scalable Design:** Component-based architecture supporting device profiles from full-featured gateways to lightweight extenders.

**Standards-Based:** Implements TR-181 data model and TR-069/TR-369 USP management protocols.

**Easily Customizable:** Standards like TR-181 are customized based on operators' needs rather than following exact specifications, enabling flexible deployment tailored to specific requirements.

**Hardware-Agnostic:** Clearly defined HAL APIs for each functions, making it easy for multiple chipset vendors to adopt RDK, as well as keeping RDK middleware platform agnostic.

RDK-Connectivity supports multiple access technologies including DOCSIS 3.0/3.1, GPON/XGS-PON, DSL (ADSL2+, VDSL2, G.fast), Fixed Wireless (LTE/5G), and Ethernet WAN with multi-WAN capabilities. The platform includes networking features such as Wi-Fi (Wi-Fi 6/6E), mesh networking, LAN bridging, VLAN, DHCP server, routing, and QoS, while security is provided through firewall, WPA3 encryption, access control, and parental controls. Device management is supported via TR-069 (CWMP), TR-369 (USP), WebPA, and WebConfig protocols, with additional features including voice services (SIP/VoIP), IoT protocol support (Zigbee, Z-Wave, Thread), IPv6 support, and DNS management.

## RDK-Connectivity Device Profiles

**Router Profile**

The RDK-Connectivity router profile offers LAN management capabilities to configure and manage local area network settings. This includes features like DHCP (Dynamic Host Configuration Protocol) server for automatic IP address assignment, NAT (Network Address Translation) for private network connectivity, and firewall settings for network security. In terms of WAN management, RDK-Connectivity supports technologies such as EthWAN (Ethernet WAN), DSL (Digital Subscriber Line), GPON (Gigabit Passive Optical Network), and LTE (Long-Term Evolution) for connections to different types of internet services.

**Wi-Fi Extender Profile**

The RDK-Connectivity Wi-Fi extender is designed to extend the Wi-Fi range for wireless clients. It operates in conjunction with the RDKB gateway and broadcasts the same SSID as the gateway. The hardware of the Wi-Fi extender is cost sensitive, and it does not require all the software components of the gateway. Acting as a Layer-2 switch, it supports RF technologies like MoCA, Wi-Fi, Zigbee, and BLE for user device connectivity. The extender can establish backhaul IP connectivity using MoCA, Ethernet, or Wi-Fi.
