A defining capability of 5G is also the design for forward compatibility—the ability to flexibly support future services that are unknown today. Q: How fast is 5G? A: Per IMT-2020 requirements, 5G is expected to deliver peak data rates up to 20 Gbps. Qualcomm Technologies’ first 5G NR modem, the Qualcomm® Snapdragon™ X50 5G modem , is designed to achieve up to 5 Gbps in downlink peak data rate. But 5G is more than about just how “fast” it is. In addition to higher peak data rates, 5G will provide much more network capacity by expanding into new spectrum, such as millimeter wave (mmWave). 5G will also deliver much lower latency for a quicker immediate response, and an overall more uniform user experience so that the data rates stay consistently high even when users are moving around. Moreover, the new 5G NR (New Radio) mobile network will be backed up by Gigabit LTE coverage foundation, which will provide ubiquitous Gigabit-class connectivity. Q: What are the key differentiating 5G technologies? A: 5G is bringing a wide range of technology inventions in both the 5G NR (New Radio) air interface design as well as the 5G NextGen core network. The new 5G NR air interface introduces many foundational wireless inventions, and in our opinion, the top five are: 1. Scalable OFDM numerology with 2n scaling of subcarrier spacing 2. Flexible, dynamic, self-contained TDD subframe design 3. Advanced, flexible LDPC channel coding

4. Advanced massive MIMO antenna technologies 5. Advanced spectrum sharing techniques For more details on these key 5G NR technologies, please read this 5G NR inventions blog post . Q: How does 5G work? A: Like 4G LTE, 5G is also OFDM-based and will operate based on the same mobile networking principles. However, the new 5G NR (New Radio) air interface will further enhance OFDM to deliver a much higher degree of flexibility and scalability. For more details on 5G waveform and multiple access techniques, please refer to this this 5G waveform whitepaper . 5G will not only deliver faster, better mobile broadband services compared to 4G LTE, but it will also expand into new service areas, such as mission-critical communications and connecting the massive IoT . This is enabled by many new 5G NR air interface design techniques, such as a new self-contained TDD subframe design; for more detailed information on 5G and to understand the specific 5G NR design components, please refer to this 5G NR whitepaper . Q: When is 5G coming out? A: 5G should be available in 2019. 3GPP (3rd Generation Partnership Project, the standards body that is helping define 5G) made a decision to accelerate the initial phase of 5G NR (New Radio) – the new global 5G standard – to begin in 2019. It is important to note that initial 5G NR deployments will focus on enhanced mobile broadband (eMBB) use cases to boost capacity and provide an elevated mobile broadband experience (faster speeds, lower latencies, etc.).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
