Gigabit experience is easier with Ericsson Radio System
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 experience – 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.
With more than 400 network deployments, 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, through the risk-free implementation of a series of future-proof building blocks.
Making best use of available spectrum for Gigabit experience
LTE can be deployed in all legacy mobile network bands, as well as other frequencies in unlicensed spectrum, using Licensed 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. Achieved through software activation, 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 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 5x20 MHz Carrier Aggregation configuration increases the peak data rate to close to 2 Gbps. Adding further carriers to the Carrier Aggregation scheme will boost peak and average data rates even further.
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 RAN Compute unit. This means operators do not need to invest in new baseband hardware as they progress from 2G all the way through to 5G
