802.11n standard, Technology that realizes throughput and reliability improvement by using multiple wireless modules for both the transmitting side and the receiving side"MIMO" was formulated, The network can not correspond to a plurality of terminals at a time and since it connects with one terminal while sequentially switching it, as the number of terminals connected to the network increases, the communication speed decreases There was a problem.

"MU-MIMO" is a function adopted by 802.11ac, but according to the announcement of QUALCOMM, by using MU-MIMO which can transmit data from the network to multiple terminals simultaneously, both terminal and Wi-Fi router If it supports MU-MIMO, it will increase the communication speed up to 3 times.

Senior Vice President Dan Rabinoyce of Qualcomm ASSERTS said, "Increasing the upper limit of network speed is not the only way to increase the effective speed of mobile communications.MU-MIMO makes efficient use of network by making time use of network efficient It is a way to do it. " MU-MIMO has adopted an algorithm to optimize the change of user's line use situation, it is technology developed over 7 years. "MU-MIMO is the next step of 802.11ac and will provide the best communication experience in response to the growing number of connected devices in the home and in the enterprise with the technology of the next step of 802.11ac," said Patrick Low, CEO of Qualcomm ASSERT. "I said.

QUALCOMM plans to sample and ship "QCA998x" "QCA999x" of the MU-MIMO chip that enables three to four simultaneous connections in the second quarter of 2014. In addition, the latest Qualcomm SoC "Snapdragon 805/801" is announced to correspond to MU-MIMO.

In addition, Qualcomm will introduce "Snapdragon 810/808Officially announced. 810 is equipped with a total of 8 cores of Cortex-A 57 quad-core + Cortex-A 53 quad core, 808 also has 6 cores total of Cortex-A 57 dual core + Cortex-A 53 quad core, both supporting 64 bit . Both SoCs correspond to Category 7 LTE. 810 adopts Adreno 430 for GPU and it corresponds to 4K output. The sample shipments of Snapdragon 810/808 will begin in the second half of 2014 and the onboard products will be released in the first half of 2015.


From QUALCOMM's announcement, it can be seen that it is certain that the specifications of mobile terminals will evolve further toward 2015.
