Qualcomm shows prototype 5g test platform that operates at frequencies below 6GHz




Qualcomm will demonstrate at the Mobile World Congress in Shanghai a test platform for 5g networks which are doing work at frequencies below 6GHz. The system consists of a base station and at user equipment “and would speeds up to 3Gbit / s possible.

Qualcomm does not mention any speed in its press release , but according EETimes that a top executive of the company said , the test set is good for a speed exceeding 3Gbit / s while the latency would be less than one millisecond. It is not known over what distance this velocity is possible, but the test system is designed to operate at frequencies around 3-5GHz, slightly higher than the frequencies that are used for 4g. Through a connection using a range of ‘over’ in the 100MHz spectrum, the higher speed is possible. When 4G is a connection 20MHz, although that can be increased with carrier aggregration.

An earlier test platform for 5g networks Qualcomm worked at a frequency of 28GHz. Also 5g test equipment from other companies worked so far mainly at high frequencies. It is expected that the 5g-standard of a broad frequency spectrum, will use; the lower frequencies are required in order to make possible a large range, while the high frequencies can provide more speed.

5g, the standard is still will not be definitively established and therefore it is not yet clear what ultimately frequencies used for 4G successor. It will go to a combination of low frequencies that have a large range, with high frequencies that allow higher speeds.

Qualcomm says his prototype contributes to the development of the standard-5g. 3gpp the organization that manages the communication standards, doing research since 2015 to 5g ‘New Radio’, as part of Release 14 of the 3GPP standard. In release 15 the 5g-standard should be finalized. Only years later, probably no earlier than 2022, is 5g to consumers in Europe.
