UniFi Cable Internet - The beginning of a new era in the modem world

Ubiquiti has introduced a brand new product in its UniFi Cable Internet line. UniFi Cable Internet is a shallow 19-inch server rack-mountable device that is a modem that works with coaxial cable according to DOCSIS 3.1 technology and features a 2.5 GbE RJ45 port.

Surely everyone knows what a coaxial cable is and what it is used for. We've all connected televisions using coaxial antenna cable. DOCSIS technology was created in 1997, with the intention of replacing earlier solutions based on proprietary data transmission protocols and modulation methods that were incompatible with each other, and was to ensure compatibility of equipment from different manufacturers.

The first DOCSIS 1.0 technology allowed data to be sent to the user over the cable network at a maximum speed of up to 42 Mbps (with a bandwidth of 6 MHz and using 256 QAM amplitude modulation) and data to be received from the user at up to 10.24 Mbps, which was unmatched by ADSL modems of the time.

Over the years, technologies have evolved, DOCSIS has undergone 3 revisions and in 2013 DOCSIS 3.1 was introduced, regulating the speed of the downstream channel to 10 Gbps or more and the upstream channel to2 Gbps through the use of 4096 QAM modulation. These data rates are comparable to fiber optics. The commercial launch of the new standard took place in 2019.

For several years in Europe, operators have been increasingly installing modems supporting DOCSIS technology in apartments. This has many advantages:

• Coaxial cable is resistant to bending and easy to repair (unlike fiber optic cable)
• Coaxial cable is cheaper than fiber optic cable
• Fiber optic-level data transmission speed

There's a reason why this technology has long been used in the United States, and they don't want to change it for something else.
Although wireless technologies are developing rapidly, and data speeds through the air can be higher than through cables, cable connections are in first place in terms of reliability. They are not susceptible to weather conditions, which positively affects data transmission.
Ubiquiti has been in the networking market for a long time and knows exactly what it takes to provide reliable and fast Internet. That's why the UniFi Cable Internet modem was created, which works on the basis of DOCSIS technology, converting the data transmission signal from coaxial cable to the local network via RJ45 cables (which are now commonly used in local networks of businesses, residential buildings and wherever there is a local network).
UniFi Cable Internet (UCI) has one DOCSIS 3.1 port (downstream 10 Gbps, upstream 1-2 Gbps) and one 2.5 GbE RJ45 port that connects to the local network. The UCI also features a 1.3-inch touchscreen that allows users to quickly obtain statistics and information about the device. The UCI, like most Ubiquiti devices, has built-in Bluetooth for quick connection and configuration with a UniFi system using a smartphone.
Like all Ubiquiti devices, the UniFi Cable Internet is reliable and can operate in a temperature range of 0 to 45° C with humidity from 10 to 95%. The UCI measures 442.4 x 80 x 43.7 mm and weighs about 1.5 kg, making it easy to install in even the smallest server rack. Its energy efficiency with a maximum power consumption of 25 W makes it attractive in a world where energy conservation plays a key role.

All in all, in an era of ever-increasing digital demands, it's hard to overestimate the importance of advanced Internet solutions like UniFi Cable Internet. Their combination of high speed, compatibility and robust design makes them an ideal choice for anyone seeking to improve their Internet experience. UniFi Cable Internet is a next-generation technology solution that provides users with fast, reliable and convenient Internet access, which is crucial in today's world.
