Ericsson Radio System for Gigabit speeds

The Ericsson Radio System, with its end-to-end portfolio hardware, software and services, will help all operators achieve superior mobile broadband performance – including Gigabit LTE – smoothly and profitably, whatever their starting point. It offers the flexibility to enable operators to try out new features in high-traffic areas, before rolling them out more widely.

The Ericsson Radio System is a robust but flexible portfolio that enables operators to invest wisely in a hardware platform which can be adapted to serve everything from 2G to 5G over time, through the risk-free implementation of a series of building blocks.

Making best use of available spectrum

LTE can be deployed in all legacy mobile network bands, as well as other frequencies in unlicensed spectrum, using License Assisted Access and similar techniques.

One key challenge for mobile operators with large legacy networks is how to achieve high data speeds and broad app coverage for LTE with disparate blocks of refarmed 2G and 3G spectrum. With the Ericsson Radio System, operators are able to implement Carrier Aggregation across multiple carriers in different bands very cost-effectively. Both capacity and coverage can be boosted through combinations of low and high bands.

Another way to boost mobile broadband performance is through higher-order modulation schemes. For example, 256QAM (Quadrature Amplitude Modulation) increases the data delivered per Hertz of spectrum to increase total data throughput by up to 30 percent.

An additional advance is 4x4 MIMO (Multiple Input, Multiple Output), which enables Beam Forming with four transmission channels and four layers in the cell, and doubles peak data rate compared with 2x2 MIMO and improves overall cell capacity.

Combining these technologies in a 3x20 MHz Carrier Aggregation configuration increases the peak data rate to close to 1.2 Gbps. Even with one of the carriers using 2x2 MIMO, peak rates of 1 Gbps can be reached. Adding further carriers to the Carrier Aggregation scheme will boost peak and average data rates even further.

One unique Ericsson Radio System software upgrade for LTE, called Ericsson Lean Carrier, delivers up to 50 percent improvement in downlink throughput while reducing dropped connections by up to 20 percent. It uses the ultra-lean design concepts (like those in the 5G Ultra Lean Carrier technology) that minimize any transmissions not directly related to the delivery of user data.

The Ericsson Radio System is also uniquely able to support both Frequency- and Time-Division Duplex (FDD and TDD) carrier aggregation and Gigabit speeds in a single Baseband unit. This means operators do not need to invest in new baseband hardware as they progress from 2G all the way through to 5G, and beyond.

Delivering Gigabit LTE to operators

Gigabit LTE network launched in China

As China Unicom's strategic partner, Ericsson is providing the technology behind China's first Gigabit LTE network. Ericsson’s Radio Dot System is allowing consumers and industry to take the first step towards 5G.

Ericsson solutions for higher data speeds

License Assisted Access

LAA allows operators to use unlicensed spectrum (in a fair and regulated manner) in combination with their licensed spectrum. By doing this, subscribers experience even more capacity and faster speeds while operators make efficient use of unlicensed spectrum resources.

Ericsson Lean Carrier

Ericsson's commitment to lead the industry in 5G research and development will also benefit today's smartphone users on LTE networks using Ericsson Lean Carrier.
