When most people have not used 3G, 4G has come. Most people seem to think that 4G is far from us, but 4G has really come to us. With the trial commercial use of China Mobile TD-LTE, 4G began to be known by Chinese people. However, few TD-LTE mobile phones can be purchased in the market, and FDD-LTE has not been disclosed in China for a long time. However, it doesn't matter. Several major operators in Hong Kong have upgraded to 4G, which can give us a 4G addiction.
Although all operators in Hong Kong have upgraded to 4G, only SmarTone supports the use of stored value cards to connect to the LTE network. That is to say, tourists who want to experience 4G network in Hong Kong can only choose SmarTone's stored value card. As a "tourist", Xiaobian has to choose SmarTone's stored value card.
Rate:
What I bought was SmarTone's HK $48 stored value card, and almost all stored value cards in Hong Kong can be obtained at a lower price on Taobao.
In fact, from the price point of view, Hong Kong's stored value cards are not cheaper than those in the mainland. However, considering that 24 yuan can use 4G with unlimited traffic throughout the day, I still feel a little balanced.
use:
With a stored value card, you can't connect to the LTE network. The best LTE support is the iPhone 5. If you want to use a phone from another manufacturer, you must pay attention to whether the purchased version supports LTE. So Xiaobian bought an iPhone 5 on the way.
After the mobile phone card is inserted into the mobile phone, the 3G switch in the cellular mobile network becomes the LTE switch. Check it and wait for the LTE signal.
I will give you a little knowledge about science popularization. If 4G is displayed next to the operator on the iPhone, it is not really 4G, but HSPA+. Only when LTE is displayed, it is connected to the 4G network. For example, the following figure shows the iPhone 5 using T-Mobile (America). Although the LTE switch is turned on, it displays 4G. Therefore, it is not connected to the LTE network, but uses 3G.
Speed:
Before releasing the speed measurement results, I want to let you know about the network in Hong Kong. The network in Hong Kong is not as comprehensive as you think, with cheap prices and fast speed. On the contrary, Hong Kong may even have no service in many places; The tariff is on a par with that of the mainland, but considering the income of Hong Kong people, it is still much better than that of the mainland; The speed is also not very optimistic. There are often signals that cannot be connected to the network, and the speed is difficult to reach the theoretical value.
In terms of speed measurement, we use Speedtest to test, and the device is still the iPhone 5.
Location 1: Hongqiao
Location 2: Tuen Mun Central 60X Bus Platform
Location 3: Tuen Mun B3X bus station
After reading the above three results, most people should come to the conclusion of "weak explosion". This speed is not even as fast as that of Unicom 3G in Beijing, Shanghai, Guangzhou, Shenzhen and Hangzhou. However, we should combine my first section of science popularization. This speed is already very good in Hong Kong, don't you believe it? Take a look at SmarTone's 3G speed bar (Tuen Mun B3X platform).
In fact, it seems that LTE in Hong Kong is still very useful. At least, you can watch videos and upload photos at a high speed. 3G is so bad that 2G can only look at it.
Summary:
Compared with WCDMA, LTE can provide more stable services to more people in the same frequency band. Therefore, in densely populated Hong Kong, operators are very active in upgrading their networks. However, for China, China Unicom has covered DC-HSPAP in the first tier cities, and the 42Mbps downlink is enough for use at this stage. Just strengthen the service and coverage, and then reduce the tariff to make it prosperous; Although Telecom has a tragic CDMA, Verizon in the United States and Au in Japan can both be used as learning objects, and they need not worry too much about future development; The most sad thing is mobile. The pressure of GSM network has not decreased. Holding the disabled TD-SCDMA is not competitive at all, so we can only bet on TD-LTE. However, with the trial commercial use of mobile, we can also experience 4G in China in the near future.
Supplement:
First of all, I apologize to all the readers. When I wrote the article, I wrote the text first and then the pictures. In order to look good, I chose the three fastest results. When I wrote the text, I looked at the original data. The average rate was about 14Mbps, which was too different from the rate that LTE should have. Moreover, Unicom 3G (HSPAP and DCHSPAP) could easily reach this rate, so it was "weak burst" Conclusion. Recently, the editor went to Hong Kong to retest. In the OFCA test in Sheung Shui, the download speed of LTE was 13913kbps, the upload speed was 4950kbps, the download speed of 3G was 7329kbps, and the upload speed was 895kbps. To download files directly, LTE has a stable speed of 1.7MB/s, while 3G has a speed of 1.4MB/s. When SpeedTest is used, the download speed is often 0. Since the speed is affected by many factors, such as the base station and the line, the speed is only for reference and only represents the speed experienced by "I" when using LTE in Hong Kong.
