通信革命5G英文演讲讲义（精选）第一篇：通信革命5G英文演讲讲义（精选）University of Bristol Zhang Zhao Han 幻灯片 1 幻灯片 2 幻灯片3 How could 5G change people’s lives?Student number: 1405074Name: Zhaohan Scott ZhangClass: 6.48 Good morning, ladies andgentleman.My presentation title is “how could 5G change people‟s life?”.I was wondering, did you want to touch your phone to check whether there was an incoming call when you heard the ringtone.If you did, it means the mobile phone is the very important thing in your life.And the way people communicate with each other has been changed dramatically.Einstein said that “I never think about the future —it comes soon enough.“ And he was right.So, I'm here to ask you to think of how the future is happening now.Over the past 200 years, the world has experienced twomajor waves of innovation.First, the Industrial Revolution brought us machines and factories, railways, electricity, air travel, and our lives have never been the same.幻灯片 4 幻灯片 5 Then the communicationrevolution brought us computing power, data networks, access to information and communication, and our lives have never been the same.In the recent years, due to the increasing user demand, wireless communication networks has been developing constantly.From 2G to 3G, the technical revolution has made big changes to people‟s life and work.And right now, 4G networks in most countries have already adopted in the business.Fortunately, according to the existing technology, the highest wireless speed has already reached 150Mbps(megabitper second).It means the videos on YouTube can be watched smoothly.Average speeds is faster than most people's home broadband.As a result, there is an argument that it is no need to upgrade current communication system, because existing networks have already been able to meet the daily needs;and the research and developmentexpenses for 5G will increase the consumers‟ burden.幻灯片6 幻灯片 7Why 5G is necessary?High speed and low latency10–100Gbps 4G’s 100–1000 times2–5msHuge capacityThe number of connected devices will reach 50 billion by 2020.To integrate existing systems seamlesslyWi-Fi(Wireless Fidelity), LTE(Long Term Evolution)and HSPA(High Speed Packet Access)However, if we compare the wireless speed to the height in real life.From 2G to 5G, you can see them here.2G is like a grasshopper,3G is like a border collie, and even 4G is just like a 5-story building.As the 5-srory building cannot meet ourdemand in real life, 4G will not meet our communication demand in nest few years.We need khalifa tower, the 5G.Of cause, 5G can meet ourdemand.Because it can provide the high speed with low latency.the rate of 10-100Gigabitpersecond, it is 4G‟s 100-1000 times.And with its ultra low latency, only 2 to 5 millisecond, it can provide the excellent user experience.Second, International telecom organization points out that the number of connected devices will reach 50 billion by 2020.At that time, each person may have the smart glasses, the smart phone, the iPad, the laptop, and the smart watch.All of these need to the internet.With the limited bandwidth resource, current networks cannot accommodate somanyintelligent terminals.And this is also a big challenge for st but not least, 5G has the ability to integrate existing systems seamlessly, including Wi-Fi(Wireless Fidelity), LTE and HSPA(High Speed Packet Access).In this way it can maximize the use of existing 幻灯片8 幻灯片9 What could 5G do?Real-time short messages for emergency resources and increase redundancy insurance.Next, we move on to what 5G could do, in another word, how 5G could change our lives.Thanks to the low latency and huge capacity, 5G would allow, for example, real-time short messages to be sent to citizens‟ smart phones immediately when the earthquake or other natural disasters are detected.Citizens can use these seconds to turn off all open flames to prevent fire disaster, and to open an exit(doors or windows)in case of deformation caused by earthquakes.And it can also be used to the high speed rail way emergency system.With the low latency …s help, the train can brake after 2millisecond when the earthquake was detected.幻灯片 10 幻灯片11 幻灯片12 What could 5G do?Real-time short messages for emergencyInternet of thingsairports, sensors around us Moreover, the internet of things is another benefit from 5G.The 5G‟s goal is everything could connect to the internet.This technology could help the airports.T oday, 10 percent of all flights cancellations and delays are caused byunscheduled maintenance events.Something goes wrong unexpectedly.This results in six billion pounds in costs for the airline industry globally every year.not to mention the impact on all of us: stress，inconvenience, missed meetings as we sit helplessly in an airport terminal.幻灯片 13 幻灯片 14What could 5G do?Real-time short messages foremergencyInternet of thingsairports, sensors around us connecting to the internet So how can the internet of things help here? 5G can develop a preventive maintenancesystem which can be installed on any aircraft.It's self-learning and able to predict issues that ahuman operator would miss.The aircraft, while in flight, will communicate with technicians on the ground.By the time it lands, they will already know if anything needs to be serviced.A system like this can prevent over 60 thousand delays and cancellations every year in Europe , helping seven million passengers get to their destinations on time.However, the 5G, the internet of things, can not only benefit the big company, but also thecommon person.A professor of MIT, bring the sensors to his house.The sensors connected to internet can feel people around them, and then open therecorder and camera to record his son‟s life.His son, after the first birthday, would say ”gaga“ to mean water.And over the next half-year, he slowly learned the right pronunciation of ”water." So we're going to look through half a year in about 40 seconds.No video here, so you can focus on the sound, a new kind of journey: gaga to water.Finally, he succeed , didn‟t he? The sensors can record every time of us, so we can look back to find our happiness.Or do other useful things.幻灯片 15 幻灯片 16 What could 5G do?Real-time short messages for emergencyInternet of thingsairports, sensors around us connecting to the internetCloud Computing Q & AThe last point I want to present is cloud computing.5G‟sdownload speed is much faster than current hard disks' speed.Which means traditional storage devices may lose their status in 5G time and would be replaced by the “Cloud”.So thatis my presentation.Here is the q&a time, I would very appreciate to answer your questions.第二篇：通信讲课讲义尊敬的各位领导，各位老师：大家好，今天我非常高兴和大家一起学习探讨。
