Access Cable Gateway Marlin L with WiFi 6


Highest Performance with DOCSIS 3.1

The CGA4236 cable gateway is fully compliant with the latest DOCSIS 3.1 specification as published by CableLabs and is capable of delivering downstream cable speeds of up to 3.6 Gbps by using 2 Orthogonal Frequency-Division Multiplexing (OFDM) downstream channels (and up to 5 Gbps in case of 2 OFDM plus 32 Single Carrier QAM) and up to 1.5 Gbps upstream by using 2 Orthogonal Frequency-Division Multiple Access (OFDMA) upstream channels.

This allows cable operators to propose multi-Gigabit data services to their customers through various applications, from IP connectivity to ultra-high speed internet access and gaming.

The MARLIN L CGA4236 offers triple-play services beyond Gigabit speeds, while providing VoIP functions for residential and business users. It is equipped with the latest Wi-Fi 6 technology, allowing for faster throughputs, better performance in dense multi-user environments and saving battery lifetime of the connected devices.

The CGA4236 has been designed to cover all regional requirements for Europe, Latin America and North America.

Wi-Fi 6 Technology

Wi-Fi 6 – a stronger and more performing wireless connectivity – is a major evolution that improves gigabit-services delivery through providing reliable connections to a large number of devices in several ways.

This evolution is intended for both 2.4 and 5 GHz, making Wi-Fi 6 the first major upgrade for Wi-Fi at 2.4 GHz since Wi-Fi 4 in 2009. While it keeps the data rate the same as Wi-Fi 5, Wi-Fi 6 increases signal robustness to accommodate more devices and allow better sharing of the wireless channel.
