韩国4G网络升级传输速度达到150Mbps

发布时间:2020-06-29 17:51:56 阅读: 来源:带式压滤机厂家

元器件交易网讯 6月28日消息,据外媒BBC报道,韩国电信称升级后LTE的4G网络下载速度已经达到每秒150兆。这比之前快两倍,是3G网络传输速度的10倍。

实际上,用户网络速度稍低一点,但电信公司称用来全高清的视频已经足够快了,另外到七月上旬,它还将提供比以前更高质量视频和音频的聊天群。

这项服务已经覆盖了包括首尔在内的44个城市,韩国电信称将来技术覆盖范围会是现在的两倍。

在英国,大部分EE的4G 网络速度最高是75兆每秒。但该公司最近称在东伦敦科技城商业区提供“双倍速度的4G”网络,据说可匹敌韩国电信网络速度。然而由于电话限制,其速度只能达到100兆每秒。(元器件交易网董蕾 译)

LTE-Advanced 4G network launches in South Korea

SK Telecom says its LTE-Advanced network allows files to be downloaded at up to 150 megabits per second.

That is twice as fast as before and 10 times the rate of its 3G service.

Although in practice subscribers will get a slower rate, the firm says it will still be fast enough to start offering a full-HD 1080p video streaming service from early July.

It also said it would offer a group video chat service with higher video and audio quality than had been possible before.

Samsung has released a special version of its Galaxy S4 handset with a new communications chip to offer access to the LTE-A system, and SK Telecom says it expects another six compatible devices to launch before the end of the year.

Existing smart devices will not be able to take advantage of the speed boost, but users who do decide to upgrade will not face additional data fees.

The service is initially being offered in 44 cities including the capital Seoul, and SK Telecom said it had plans to double that number in the future.

Speed and capacity

In the UK most of EE"s 4G network currently tops out at 75Mbps.

But the firm recently installed equipment in East London"s Tech City business cluster to offer a service it calls "double-speed 4G", which it says can match SK Telecom"s LTE-A network kit.

However, limitations with the handsets it offers means the maximum theoretical speed they could access would be 100Mbps.

Real-world download speeds will be slower than the 150Mbps maximum quoted by SK Telecom

While speedier downloads may prove enticing to customers, one analyst said that they were only part of the picture.

"I"ve never found someone who didn"t want something faster," said Daryl Schoolar, an analyst at the telecoms consultant Ovum.

"But it"s not just about speed - the issue of capacity is perhaps more important. These advances allow operators to use more spectrum which means they can handle more subscribers at once.

"The networks are like a highway - the more people who use them the more clogged they get. By adding the equivalent of more lanes operators ensure that subscriber speeds don"t slow down as much at the busiest network times."
