What effects mobile Internet speed? -Smart phones, Internet-IT news

Why no signal, and the damn network!

As communication users again and again in everyday life like complaining when they first thought, perhaps the telecom operators work hard to set up the network still is not good enough, not fast enough, but in fact, behind this, factors that affect the speed of mobile Internet, signaling bad cell phone, you need to know--behind the "culprit" there are a lot!

* Questioned the same place, different mobile phones, why is the signal strength is poor so much?

Culprit cell phone quality is going to

As we all know, we can happily call cities, mountains and even the sea, with Telecom operators in the us to set up a large number of communications base stations. Typically, as long as our mobile phone to quickly and seamlessly connect to the base station, then Internet access speed would not be bad.

Want phone perfectly between the base station and to send and receive messages, also need to refer to phone a special chipset--modem (Modem). Our mobile phones are connected to 3G, 4G networks, the ability to connect multiple bands, has excellent anti-jamming capabilities, data transfer speed, and so on, depending on the Modem's performance. This also explains why some brand burst signal bad news at home and abroad, largely due to poor performance of its Modem chipsets.

So, don't think that you, me and him in the hands of mobile network performance is the same, this one is about. Now internationally recognized as the most Modem performance chip manufacturer Qualcomm and Intel, Huawei, Samsung is more mainstream providers.

* Question my phone even Wi-Fi, he even 4G, why so much faster speeds?

Culprit b don't let the Wi-Fi fool you

Do not be coy, even Wi-Fi will be faster than the continuous 4G speeds? Actually, it never happened.

If you look at the digital press, may recall that some time ago a large number of MTK Helio X10 (MT6795) Wi-Fi phone encountered stop for no reason. Communication performance of mobile phones can be done in Wi-Fi and 4G intelligent switching between networks, weak Wi-Fi signal when connected automatically 4G; on the contrary, if the phone can't do it on automatic intelligent switching between Wi-Fi and 4G efficiently network, then Wi-Fi environments there may be "slow speed".

Similarly, communication performance of mobile phones can also improve the efficiency of the Wi-Fi connection and achieve faster download and upload and vice versa, if the performance is not good, even if there is an available Wi-Fi, so also no speed advantage to play. "Wi-Fi signal but not even on, even on speeds of only a few KB per second", most people will think that this is the operators covered by the network is slow, but backward in mobile communications increased network congestion.

* Question or signal full, a Flash, speed goes down?

Masters three-fear of fog rain most afraid of "seal"

4G wireless signal is transmitted in the air, so many external factors influencing quality of wireless network, even if wind, rain and fog will significantly impact our mobile Internet speeds, typically, rain and snow weather wireless network quality will be slightly less.

In the complex structure of the building, corridors, basements, and other places, which is usually a communication signal serious occlusion, if you find these good cell phone reception, then congratulations, you are likely to be carriers specialise in indoor coverage; on the contrary, if the signal is poor, it indicates that wireless signals from an outdoor base station, indoor coverage is not ideal.

Similarly, subways and elevators closed environments, such as mobile phone signals are not sent directly, unless the carriers specialise in coverage. But some building property prices soar, operators charge exorbitant entry fee, hinder the construction of carrier signal coverage comes into play, and gave the signal quality at these places a hidden danger.

* Question speed stripes last night, what becomes very slow this morning?

Masters what four are unable to carry many

Different from exclusive broadband, 4G Internet connection is shared, with people much of the time, the speed will slow. This also explains why the crowded on my way to work, usually on slower connections, and by night, network environments immediately becomes good.

Planning and Design Institute of China Academy of telecommunication Wang Aihua, the Chief Engineer at the Ministry, for example, only one user may rate of up to seventy or eighty, eighty or ninety trillion; but if 10 people using one, it may be everyone four or five such cases. Each base station has a capacity limit, crowded places and sometimes poor speed perception.

So typically, district, office buildings and other locations with high pedestrian flow is often more prone to network congestion, although the telecom area Chamber of Commerce according to the actual situation to increase this coverage strength, but tend to avoid flow surge, unbearable pressure on the network. Believe in sports events and performances, many users have experienced the taste of network congestion, these are the people to blame.

* Question why the network is normal, App can't download?

Masters five certain Internet services does not give force

Because different App to set up the different types of network servers, network server failure or because the number of downloading too much may cause the download was not successful.

This means that your mobile phones, base stations near you, and so forth are all normal and good, but you want to get Internet service which corresponds to the server not to force. At this point, you can try to log into another site, or try other Internet service, if speed is normal, then instructions are likely to be a problem with an Internet service provider.

For example, all Apple App Store the app store has to login are often unable to ensure smooth login, many users often do not speed or slower. At this point, maybe we'd have to try it another time.

* Question why my cell phone Internet access speed is getting slower?

Masters six my phone "is a disease"

Please, not your cell phone Internet access speed is getting slower, in fact, is your phone's performance is getting worse, cause you experience feeling-the Internet is slow. Contributing to this result for many reasons, such as Android phones use low too long, configuration, virus, software installation, no keep 4G services, etc.

Usually situation Xia phone especially Android phone variable slow of most main reasons has three: large phone application will boot since started, led to phone memory was large occupied; many Ann Zhuo phone in factory Shi are has pre-installed large of pre-installed software, this phenomenon in China domestic phone in the is common, large of useless pre-installed software not only cannot uninstall and also occupied has phone of large memory, effect phone run speed; seems a application has through its since with of "exit" function close has, can actually is still in phone background resides, "Nail House".

At present, for Android phones more and more cards, no cure for good. Ordinary users can use the Mobile Assistant software to regularly clean up the useless applications, memory, cache, data, mobile phones speed.

到底是什么在影响手机的上网速度？ - 智能手机,网速 - IT资讯

怎么又没信号了，这该死的网络！

当通信用户在日常生活中一遍又一遍发出类似抱怨的时候，他们第一个联想到的，也许是电信运营商辛苦架设的网络仍然不够好、不够快，但其实在这背后，影响手机上网速度的因素不少，面对信号糟糕的手机，你必须知道——背后“祸首”有很多！

*质疑同样的地点，不同的手机，为何信号差那么多？

祸首一 手机品质差别可不小

众所周知，我们能够在城市、大山甚至大海里愉快地打电话，与电信运营商在我们身边架设的大量通信基站有关。通常情况下，只要咱们的手机能够快速、顺畅地连接上基站，那么上网速度肯定差不了。

而想要手机完美地与基站之间收发信息，还需要提到手机中一块特殊的芯片组——调制解调器(Modem)。我们的手机能连上3G、4G网络、能够连接上多个频段、有出色的抗干扰能力、数据传输速度快等等，都取决于Modem的性能好坏。这也解释了，为何某些国内外品牌曾爆出手机信号不好的新闻，主要原因就是其Modem芯片组性能较差所致。

所以，别以为你我他手中的手机连网性能都是一样，这其中还是有讲究的。目前国际上公认的Modem性能最强的芯片厂商是高通，同时，英特尔、华为、三星也是较主流的提供商。

*质疑我的手机连Wi-Fi，他的连4G，为啥他的网速快那么多？

祸首二 别让Wi-Fi欺骗了你

别天真了，连Wi-Fi就一定比连4G网速更快？事实上，还真没那回事。

如果你关注数码新闻，也许记得，前段时间大批采用MTK Helio X10(MT6795)的手机遇到Wi-Fi无故断流的情况。通信性能好的手机可以做到在Wi-Fi和4G网络间智能切换，Wi-Fi信号不佳的时候自动连接4G；相反，如果手机无法做到在Wi-Fi和4G高效地自动智能切换网络，那么就有可能出现Wi-Fi环境下的“慢网速”。

同理，通信性能好的手机还可以提高Wi-Fi连接的效率，实现更高速的下载和上传；反之，如果手机的通信性能不好，即便有可用的Wi-Fi，也照样发挥不出速度优势。“Wi-Fi信号满格但连不上，即使连上了每秒网速也只有几kb”的状况，大多人会以为这是运营商覆盖的网络慢，殊不知落后的手机通信性能也加剧了网络的拥堵。

*质疑刚刚还是信号满格，一转眼，就网速大降？

祸首三 怕雾怕雨最怕“封”

由于4G无线信号是在空气中传播的，所以影响无线网络质量的外界因素非常之多，哪怕风、雨、雾都会明显影响我们的手机网速，通常情况下，雨雪天气的无线网络质量会略差一些。

而在结构复杂的大楼、过道、地下室等地，这些位置通常都属于通信信号严重遮挡区域，如果你发现这些地方手机信号良好，那么恭喜你，很可能是电信运营商专门进行了室内信号覆盖；相反，如果信号差，那就说明此处无线信号来自室外基站，室内覆盖效果并不理想。

同理，地铁和电梯等封闭环境手机信号都无法直接送达，除非电信运营商专门进行覆盖。可有些大楼物业等坐地起价，向运营商收取高额进场费，阻碍运营商进场进行信号覆盖施工，于是给这些地方的信号质量留下了隐患。

*质疑昨晚网速还杠杠的，怎么今早就变得超慢？

祸首四 什么事儿都扛不住人多

与独享宽带不同，4G网速是共享使用的，用的人多的时候，网速自然会变慢。这也解释了为何拥挤的上班路上，通常网速较慢，而到了夜深人静时，网络环境立刻变得不错。

工信部电信研究院规划设计研究所总工程师王爱华举例：只有一个用户在用，可能就能达到七八十兆、八九十兆的速率；但是如果10个人在用，那可能就是每个人四五兆这样的情况了。每个基站都有容量限制，人流密集的地方有时会网速感知较差。

所以通常情况下，商圈、办公楼等人流密度高的地点常常较容易出现网络拥堵的情况，虽然电信运营商会针对实际情况增加此类地区的网络覆盖强度，但实际情况往往仍难免出现人流暴增，网络不堪压力的情况。相信在体育赛事和演出等现场，不少用户都曾体会过网络拥堵的滋味，这些都是人多惹的祸。

*质疑为什么网络正常，App却下载不了？

祸首五 某些互联网服务不给力

因为不同的App架设在不同的网络服务器上，网络服务器的故障或因为下载人数过多都有可能引起下载不成功。

此类情况意味着，你的手机、你附近的基站等等因素全都是正常和优良的，可偏偏你想要获取的互联网服务所对应的服务器不给力。此时，你可以试着登录其他网站，或试用一下其他互联网服务，如果速度正常，那么就说明很有可能是某个互联网服务的提供方出了问题。

例如，所有果粉都得登录的App Store苹果应用商店就常常无法保证顺畅登录，不少用户经常出现登不上或速度较慢的情况。此时，也许我们只能换个时间试试了。

*质疑为什么我的手机上网速度越来越慢？

祸首六 原来我的手机“一身都是病”

拜托，不是你的手机上网速度越来越慢，其实是你的手机综合性能越来越差，导致给你的使用体验感觉就是——上网慢了。造成上述结果的原因很多，例如安卓手机使用时间太久、配置较低、中病毒、软件安装过多、没有及时升级4G服务等。

通常情况下手机特别是安卓手机变慢的最主要原因有三：大量手机应用会开机自启动，导致手机内存被大量占用；很多安卓手机在出厂时都已经预装大量的预装软件，这种现象在中国国产手机中很常见，大量的无用预装软件不仅无法卸载而且还占用了手机的大量内存，影响手机运行速度；看似一个应用已经通过其自带的“退出”功能关闭了，可实际上却仍在手机后台驻留，做了“钉子户”。

目前，对于安卓手机越来越卡的情况，尚无根治良策。一般普通用户可以通过手机助手类软件定期清理无用应用、存储空间、缓存数据等，来实现手机提速。
