5G-Ready iPhone 12 Might Ship Without 2×2 MIMO Support, Resulting in Slower Upload Speeds
Massive MIMO (Multiple-input multiple-output) technology is expected to be a core component of 5G networks. Compared to a regular network, a MIMO network can multiply the capacity without needing more spectrum. This can benefit data rates and link reliability. Earlier, it was believed that one of the iPhone 12 features would include support for 2×2 MIMO, but apparently that won’t be the case.
The prediction had come last year from revered analyst Ming-Chi Kuo who said that the 5G-capable iPhone 12 range will support 2×2 MIMO uplink, benefitting both WIN SMI and Broadcom because of the use of six power amplifiers. However, he has revised his predictions and now believes that the iPhone 12 will have just two amplifiers at most and will likely not support 2×2 MIMO uplink.
