Introduction to 4G technology on Oppo K9
Mobile telecommunication technologies evolve by one generation nearly every 10 years. 4G is the fourth one, which officially started in 2009 in South Korea, and years after that it was provided in all populated areas. And by “they” we mean all cellular network operators around the globe.
They follow the International Telecommunication Union (ITU) specifications. According to the ITU, a 4G labeled technology has fast internet speeds, achieving ten times the speed of 3G internet. And it has also low latency.
A lot of protocols were identified 4G such as: LTE, LTE+, and HSPA+.
Advantages of 4G on Oppo K9
4G has all the features of 3G at more speed. It allows download speeds of around 14 Mbps up to speeds as high as 150 Mbps, five times faster than 3G. And it allows more than ten times the uploading data speeds of 3G, ranging from 8Mbps up to 50 Mbps.
Low latency is another feature, it ranges from 60ms to 98 ms, Despite the fact that it’s only a bit lower than 3G, it is very vital for some use cases including video conferencing or online gaming, and other live interactions.

What are 4G bands? and which bands are available in the Oppo K9?
4G and other cellular technologies use radio waves to transmit data. These waves have different lengths and frequencies. To prevent interference between signals, governments and the ITU decided which regions use which frequencies for 4G.
Each region has been designated certain frequency intervals termed bands. Band number 7 and band number 28 (for example) are used on a global scale.
What you should know as a consumer is that each cellular operator grants specific bands according to the area, and different phones support different bands. So you have to make sure that your Oppo K9 supports the bands provided by your local mobile provider.
