According to the Federal Communications Commission on May 23 local time disclosure application documents show that Apple plans to test a new generation of wireless Internet technology near the company headquarters. The application details the plan for Apple to test a 5G Internet connection using millimeter-wave technology. Starfound, an Internet startup, is trying to use the same technology to provide home users with a gigabit WiFi connection.

According to an article published by Business Insider, Apple's application documents show that "Apple plans to use this spectrum to evaluate the performance of direct connections between base station transmitters and receivers and cell phone connectivity in a multipath environment. These assessments will provide carriers with the next 5G Network equipment operation related technical information. "

The 5G is still a somewhat vague concept as standards organizations have yet to set standards, and it is widely believed that millimeter-wave technology can provide gigabit speeds. As data is transmitted at higher frequencies (30 GHz - 300 GHz), millimeter-wave technology reduces latency and increases system data transmission capacity. It also offers the possibility of reducing the antenna size and integrating a more powerful multi-band antenna in one device.

In general, 5G Internet connection speed is several orders of magnitude of standard LTE. Of course, there are still major technical challenges in millimeter-wave technology that need to be addressed. The major ones are transmission distances that are not far enough to penetrate a large amount of surface material, including glass. Apple seems determined to test this technology to be used in future products.

The application states that "Apple intends to transmit signals from two fixed locations in the facilities at Cupertino and Mabida, signaling the same parameters and equipment as in the Form 442 document, including the use of E, H plane half The power beam width is 20 degrees and the dip angle is 20-25 degrees Horn antenna. Apple does not expect the test period to exceed 12 months. "

Apple will only be responsible for testing the hardware part - may be related to the production of new iPhone. In view of Qualcomm's patent law battle, Apple may also consider changing the different smart phone modem providers. Before 5G technology was used on smartphones, there was still a lot of work to be done by network operators for telecoms operators, chipmakers and standards organizations, which could take two or three years.

AT & T, Verizon, Sprint and T-Mobile each announced plans to begin testing the 4G LTE, a faster version that, in theory, will help lay the groundwork for a true 5G network in the future. On the chip side, Samsung, Qualcomm and Intel both announced new hardware that supports 5Gbps. The telecom standards organization 3GPP is stepping up its efforts to release the first 5G standard in the second half of this year and to fully test and deploy the 5G network by 2019.
