People are uploading photos to social media like crazy. Instagram users have shared 16 billion photos since its 2010 launch. Every day, people place 350 million photos on average on Facebook, and the company claims 78% of its US users are mobile users. And that means the uplinks in smartphone-dominated networks are coming under increasing strain.
Enhancing network software is a neat way to help ensure that the uplink does not cause a downbeat customer experience. Three NSN tried and tested software upgrades are worth deploying to provide smartphone users with faster uploads to social media and cloud storage for an improved experience.
1. NSN’s HSUPA (High Speed Uplink Packet Access) Interference Cancellation Receiver software uses a unique algorithm to reduce the interference caused by high bit rate HSUPA users. All HSUPA data and voice users benefit, with total uplink throughput increased by as much as 50%. This gain also results in better coverage and smooth uploading of users’ content. Reduced interference also extends the device’s battery life by halving its transmission power for the same throughput.
2. Frequency Domain Equalizer (FDE) achieves an average 10-20% gain in uplink throughput by eliminating interference caused by the terminal’s multipath signals, which are received by the base station with different delays. The software effectively optimizes the base station’s receiver for higher HSUPA data speeds, enabling end users to experience uplink bit rates greater than 2.5 Mbps in good signal conditions.
3. The third software upgrade focuses on Block Error Ratio (BLER), which is the number of incorrectly received blocks divided by the total number of transmitted blocks. BLER is a measure of data transmission quality. Typically, a base station’s power output is adjusted according to a static BLER value, (BLER target) set by the operator. The new NSN Dynamic HSUPA BLER software allows an operator to define a variety of BLER targets for different radio conditions and traffic types. As conditions change, the software automatically adjusts the BLER target to improve HSUPA cell throughput by up to 20% and increase coverage. Users enjoy higher uplink peak rates and cell edge throughput, as well as longer device battery life thanks to lowered transmission power.
So, as uploading pictures and other content from smartphones continues to follow a rising trend, you could say NSN software upgrades deliver a picture-perfect solution.
