Highest Performance with DOCSIS 3.1

The CGA4236 perfectly matches the requirements of cable network operators who want to offer their customers ultimate broadband access.

The cable gateway is fully compliant with the latest DOCSIS 3.1 specification and can deliver downstream cable speeds of up to 3.6 Gbps by utilizing 2 Orthogonal Frequency-Division Multiplexing (OFDM) downstream channels (and up to 5 Gbps in the case of 2 OFDM plus 32 Single Carrier QAM) and up to 1.5 Gbps upstream by using 2 OFDMA upstream channels.

WiFi 6 Technology

WiFi 6 improves the delivery of Gigabit services by providing reliable connections to a large number of devices in various ways. This advancement is intended for both 2.4 GHz and 5 GHz, making WiFi 6 the first major upgrade for WLAN on 2.4 GHz since WiFi 4 in 2009.

While the data rate remains the same as WiFi 5, WiFi 6 increases signal robustness to accommodate more devices and enable better shared use of the wireless channel.

WiFi 6 offers a higher maximum data rate in the network by using higher modulation orders for more data – up to 1024 QAM compared to WiFi 5's 256 QAM.

Furthermore, WiFi 6 provides a mechanism to reduce interference between neighboring routers through efficient frequency utilization and improve service quality for customers living in high WiFi density areas.

Finally, WiFi 6 introduces a concept called Target Wake Time (TWT), which allows the Access Point to put client WLAN transmitters into a sleep mode until needed, resulting in power savings and longer battery life.

Superspeed USB

The CGA4236 features Superspeed USB 3.1 Gen 1 master ports for supporting, for example, mass storage devices, and enables transfer speeds that are many times higher than conventional USB 2.0.
