According to VentureBeat, Qualcomm senior vice president Durga Prasad Malladi said in an interview that the company is preparing to launch its first 5G smartphones in 2018 instead of 2019. They can be up to 4Gbps. Although most operators and equipment manufacturers are preparing to launch 5G devices next year, some vendors will be preparing standard-compatible smartphones later this year, providing twice or four times the speed of top 4G/LTE devices.
Qualcomm CEO CrisTIano Amon announced that 19 manufacturers and 18 operators will use X50 modems to introduce 5G devices to customers in 2019.
Maradi explained that although almost all equipment manufacturers are focusing on the release of 5G products in 2019 (specifically since the beginning of 2019), some companies are working hard to release them in some areas. He said: "The technology of some operators is actually available and hopes to commercialize it by the end of 2018. We are doing everything we can to help them."
Operators are determining the final speed of the early 5G devices they support. Maradi said, "The speed may range from 1 Gbps to 4.5 Gbps, depending on which band they operate in. They usually start at 2 Gbps or 4 Gbps (equivalent to 2 to 4 times the peak speed of 4G/LTE networks). ."
Qualcomm previously said that when 5G is not available, LTE will act as a “regressionâ€. If you get the operator's network support, its speed can reach 1Gbps. But users should expect true 5G speeds, especially in densely populated urban areas.
Maradi said: "Based on millimeter wave experiments in cities like San Francisco, 50% of users can enjoy 1.4Gbps speed, which will change the way you do things. When your laptop or tablet reaches this speed Your consumption will change dramatically. Providing fixed 5G home broadband services for desktops and TVs (Verizon's original plan) is more 'simple' than the engineering challenge of providing this speed for mobile and portable devices. ."
Maradi also talked about the problem of multi-band support, that is, a single device can work in different radio frequencies of 5G. Qualcomm has pledged to support global carriers at the time of its technology release, with current frequencies ranging from 600 MHz to 2.5-4.9 GHz to the millimeter wave 28 and 39 GHz bands.
Maradi expects that the service performance of operators is very similar regardless of the frequency band. These operators may provide 100MHz IF spectrum or 800MHz millimeter wave spectrum, and can correctly use beamforming and huge MIMO antenna. Although the network design will limit the performance of 5G in the real world, it can reach 4Gbps in the IF and millimeter wave bands.
Qualcomm said in January that it expects to showcase its first 5G phone at CES next year, but this schedule has been significantly delayed by several months due to pressure from operators and equipment manufacturers. Maradi's comments may pave the way for operators like AT&T to go beyond their previous plans and start offering mobile 5G services and personal hotspots.
