2018 iPhones to Feature Upgraded Antenna Design to Boost LTE Transmission Speeds
Kuo says new iPhone models will use at least two LCP LTE antenna modules, much like the iPhone X, but with improvements to support 4x4 MIMO standards.
Antenna design upgrade a key factor in anticipated boost to LTE transmission speed in new 2H18F iPhone models. As a LTE antenna FPCB material, LCP is superior to PI in properties related to high-frequency, thermal performance and moisture resistance. We predict 2H18 new iPhones will be equipped with two LCP LTE antenna modules same as iPhone X or more, but with higher specs to support 4x4 MIMO standards.Last week, Kuo said Apple is expected to use Intel XMM 7560 and Qualcomm Snapdragon X20 modems in its next-generation iOS devices, enabling faster LTE transmission speeds. Both of those chips support the previously mentioned 4x4 MIMO technology, compared to 2x2 MIMO in the current iPhone models.
4x4 MIMO, or Multiple-Input Multiple-Output has the potential to significantly improve LTE transmission speeds by increasing the number of data paths between a cellular tower and an iOS device to four.
In previous notes, Kuo has said Apple is working on a total of three iPhones for 2018, including a 5.8-inch OLED model that's similar to the current iPhone X, a 6.5-inch OLED model that can be thought of as a sort of "iPhone X Plus," and a new 6.1-inch LCD model, designed to sell at a lower price point. All three, says Kuo, will include edge-to-edge iPhone X-style displays and Face ID support.
Kuo believes Apple will ship an estimated 100 to 120 million iPhone units in the second half of 2018, something he has previously said will fuel an upgrade "supercycle" during the year.
