A truly flexible radio system
The Ericsson Radio System with its end-to-end portfolio hardware, software and services, help operators to achieve superior mobile broadband performance – with Gigabit speeds – 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.
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 networks is how to achieve high data speeds and broad app coverage for LTE with different blocks of re-farmed 2G and 3G spectrum. With the Ericsson Radio System, operators can implement carrier aggregation across multiple frequency bands very cost-effectively as FDD and TDD are both supported from the same Baseband. Capacity and coverage can be boosted through combinations of low and high bands.
Another way to boost 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, doubles data rates compared with 2x2 MIMO and improves overall cell capacity.
