Ericsson 5G innovation promises 50% higher speed on LTE

LTE network access
Telecom network vendor Ericsson today said its 5G innovation will introduce lean design concepts to 4G LTE networks that will offer up to 50 percent higher speed.

Ericsson Lean Carrier significantly improves downlink data speed by up to 50 percent on today’s LTE devices. Ericsson Lean Carrier can be implemented within Ericsson’s LTE networks today, and the solution is compatible with all LTE devices.

It increases the amount of time during which the new 256 Quadrature Amplitude Modulation (QAM) encoding scheme can be utilized by up to 280 percent and extends its benefits to outdoor macro environments.

# Ericsson Lean Carrier reduces the level of reference
# Ericsson 5G innovation promises 50% higher speed on LTE
# network average increase of about 10%
# to enhance performance at cell edge area and user experience
# Ericsson Lean Carrier increases the use of 256 QAM by up to 280%

Ericsson said its Lean Carrier innovation is first to address intercell signaling interference, introducing lean design concepts to 4G LTE to improve data speed and app coverage for users while on the road to 5G.

Ericsson Lean Carrier is running live in thousands of cells in SK Telecom’s network where Ericsson and SK Telecom have now deployed Ericsson Lean Carrier in urban, suburban and rural areas. In a large-scale deployment, users can enjoy up to a 50 percent increase in downlink data speed with a network average increase of about 10 percent.

“Through this technology commercialization on LTE base stations, we can expect to enhance the performance at cell edge area and user experience,” said Park Jin-hyo, senior vice president and head of Network R&D Center, SK Telecom.

By reducing interference, Ericsson Lean Carrier enables new 256 QAM higher order modulation to be utilized over a broader area, extending the higher data speed advantage to the outdoor macro environment. Ericsson Lean Carrier increases the use of 256 QAM by up to 280 percent.

Leveraging the power of the Ericsson LTE baseband hardware combined with Ericsson’s software scheduling algorithms, the Ericsson Lean Carrier innovation applies the design concepts being developed for future 5G systems to today’s 4G LTE networks.

Ericsson Lean Carrier reduces the level of reference signaling needed for good network performance. This leads to a corresponding improvement of the downlink data speed which applies to all parts of the 4G LTE network.

Per Narvinger, head of LTE, Ericsson, said: “When LTE was created in 2008, it was straightforward, powerful technology, but now we have added significantly more intelligence. Running signaling full-blast limits performance by creating unnecessary intercell interference.”

Telecom network operators are beginning to adopt advanced encoding schemes to handle demands for improved user experience. Use of the new 256 QAM higher order modulations requires clean radio signals to increase the downlink data speed. By reducing interference Ericsson Lean Carrier increases the amount of time during which 64 QAM and 256 QAM encoding schemes can be utilized by the LTE system.
