Mobile performance is an important factor for the success of an online shop. Poor performance on mobile devices can lead to a poor user experience and cause potential customers to leave the shop without buying anything. The OXID eShop must therefore be optimised for a wide range of bandwidths to ensure that performance is satisfactory on all devices and networks.

Bandwidth problem

One of the biggest issues online shops face is the varying bandwidth used by mobile devices. While some devices run on fast 4G or 5G networks, others still use 3G or even 2G networks. This means that the same web page may load at different speeds on different devices and networks.

5G, 4G, 3G and 2G are different mobile data transmission technologies that offer different speeds and bandwidths.

5G offers the highest speed and bandwidth of all available technologies and can achieve speeds of up to 10 Gbps and latency of less than 1 millisecond. This means that 5G is able to transmit very large amounts of data very quickly, making it ideal for use in applications such as virtual reality and augmented reality.

4G offers lower speeds and bandwidths compared to 5G, but still significantly higher than 3G. The average download speed of 4G networks is around 15 Mbps, while latency is in the range of 20-30 milliseconds. 4G is the most widespread technology for mobile data transmission and is mainly used for smartphones and tablets.

3G has even lower speeds and bandwidths than 4G and achieves average download speeds of around 3 Mbps. Latency times are around 100-200 milliseconds. 3G is still widely used, especially in rural areas or in developing countries where 4G networks are not yet sufficiently available.

2G offers the lowest speeds and bandwidths of all available technologies, achieving average download speeds of around 0.1 Mbps. Latency times are 500 milliseconds or more. 2G networks are most prevalent in rural areas or in developing countries where 3G or 4G networks are not available.

The average loading time on websites worldwide is 2-3 seconds on 4G, 3-4 seconds on 3G and more than 4-5 seconds on 2G. These times can be reduced through technical optimisation.

Optimisation approaches

To optimise performance on mobile devices, there are a few approaches that OXID eShop can take. One of the most important is to minimise the size of the pages, especially by using compressed images and reduced CSS and JavaScript files. Another is to write the code to run more efficiently by avoiding unnecessary queries and calculations.

On the server side, other techniques can be used, such as caching, to reduce page load time so that pages do not have to be recreated each time they are accessed. A CDN (Content Delivery Network) can also be used to reduce loading time by delivering content from servers close to the user.

Conclusion

To ensure satisfactory performance on mobile devices, the OXID eShop needs to be optimised for a wide range of bandwidths. This can be achieved by reducing the size of pages, writing code more efficiently and applying server-side optimisations such as caching and using a CDN.

There are also responsive design techniques that can be applied to improve the user experience on different devices. These techniques ensure that the website automatically adapts to the screen size of the device and the content is presented in a way that is optimal for mobile devices.

It is also important to run regular tests to ensure that performance on mobile devices is always satisfactory and that any problems can be quickly identified and fixed. Overall, mobile performance is an important factor for the success of the OXID eShop and requires a continuous effort to ensure that the user experience is optimal on all mobile devices.
