still stuck with 4G speed….
What category your 4G…..
Before talk about it and the next generation of it. We will talk about 4G Communication. 4G is next generation from 3G. The big difference is multiple frequency of carrier. In first 3 Generation have one specific carrier frequency. Time Based or Frequency Base is technology behind it. In 4G multiple frequency supported by MIMO (Multiple Input Multiple Output) technology. This technology need more than one antenna. In 4G there are many category describe in picture.
In indonesia max in category 4 and 5 because limitation of free frequencies. Not much country have category 14 and 19.
In Germany implemented Cat.16 LTE in Oct 2017 and in Italy in Mar 2018. Demonstrated with vondafone as provider. In another just in cat 6 or 11. In cat 11 like Belgium (Aug 2017), Cyprus (Jul 2017), Hungary (Nov 2016). Technology upgrade consume more money in every step.
5G is reborn of High frequency transmission
5G is the same models with MIMO but in expert ways. in 4G some provider used frequencies below 6 GHz. In 5G use extremely high frequencies in the 30 GHz to 300 GHz range. High frequencies mean more fast to transmit and receive. Higher frequency transmissions have more bandwidth than lower frequency transmissions. With higher frequency transmissions promised more data to transmit. But this feature become benefit if transmission close with limit. Now cellular transmission near the boundaries, like browsing streaming, Internet of Things etc.
Higher frequency transmissions not warranty transmission quality in all areas. High frequency transmission devices can’t communicate from as great a distance as low frequency devices. HF band can communicate as far as 1,800 miles apart difference with high frequency transmission in less area. High frequency broadcasts are less susceptible to interference from electronic sources, while low frequency transmissions are less susceptible to interference from physical objects like walls that block communication.
rea also celluler effect for health
5G still use technology of smart antennas. Smart antenna is transmit only for the requested client only. Antennas in common use technology like water. It will transmit to all area. Towers that fire data in all directions, potentially wasting energy.
