Energy costs

Mobile Network Operators all over the world are facing an increase in energy costs. One of the main energy consumption factors is Over Air Transmission which requires high energy to operate. More than 70% is consumed by the Radio Access Network (RAN). Electricity prices are rising, and this is a continuous tendency all over the world. Radio Spectral Efficiency and data volume consumption relates directly to the RAN power consumption. Therefore, improving Radio Spectral Efficiency and Smart Volume management leads to significant savings in energy usage at mobile operators. Those improvements can derive mainly from the Core Data Network with advanced Data Management techniques by Flash Networks. Using proper efficiency techniques can reach cost savings of $10’s Millions annually. Greenhouse gas concentrations are at their highest levels in 2 million years and emissions continue to rise. As a result, the Earth is now about 1.1°C warmer than it was in the late 1800s. The last decade (2011-2020) was the warmest on record. The consequences of climate change now include, among others, intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms, and declining biodiversity. It is therefore imperative to reduce energy usage in order to reduce greenhouse gas concentration and rescue the planet. Mobile video takes a large share of around 70% of the total data volume. The amount of data to transfer a video in DVD quality (480p) is 4x less than delivery in full HD (1080p). Similarly, the amount to transfer a video in full HD is 4x less than delivering in 4K. When a video with nearly the same quality can be transferred with less energy than the MNO will see lower costs and the customer will notice longer battery life.

Energy saving

Harmony by Flash Networks can significantly optimize energy spending and save the operator millions of dollars with an innovative 3-dimensional solution that cuts MNO electricity costs. Flash Harmony is the only 3-dimensional optimization in the world that can reduce energy spending and increase user quality of experience without reducing the quality of the video or the user experience. Harmony 3-dimensional optimization: Volume, Speed, and Control can achieve Energy savings by increasing Radio Spectral Efficacy from the Data Core. At the same time, mobile operators can maintain high Quality of Experience.

Dimension 1 - Volume

Watching video in 720p on phones uses 1/20th of the energy resources of a 4K video, but reducing the resolution is not the only way to control Volume. Part of the video traffic is not using ABR protocol (like TikTok) and needs new techniques like Flash Data Management. For example, the Data Management solution can reduce TikTok volume by controlling the background traffic load on the network is similar to Buffer Tuning at the Progressive Download video protocol technique. Another technique is the Just In Time unique feature. It measures and reduces the greedy and too-long future video frames buffer sent to the UE. Just In Time and Data Management solutions by Flash Networks are helping reduce the volume with keeping the same video resolution and the best QoE

Dimension 2 - speed 

TCP Acceleration by Flash Networks is a patented Congestion Control Algorithm, including sub-features, that enhances every network bearer and condition uniquely. TCP Acceleration, in 24 hours, improves the speed and maximizes bandwidth. It provides faster speed for every user and increases the Radio Spectral

Dimension 3 - Control and signaling 

Energy saving by avoiding unnecessary paging, RRC state changes, and staying longer in RRC idle state. Enable more efficient Radio and UE power usage.
Radio spectral efficiency is enhanced by queuing at the core unnecessary transport layer control messages.

Use case 1

Assuming 10 GB of video consumption per customer per month with Flash technology the Energy Saving can reach €1.728 million per year.

Use case 2

Assuming 120 Petabytes of data per month in the network, with Flash technology the Energy Saving can reach € 1.1 million per month for the RAN and an additional €195000 in the core. In total this equates to savings of 35 TWh or €15.5 million per year.
An average household of 4 may use 4000kWh per year. So the saved energy would allow delivering energy to an amazing 8750 households with 35000 people. Enough energy for a small town may be saved.

One tool for all your mobile traffic optimization and monetization needs.
