Introduction to Mobile WebMobile Product List

TV-based devices, including: Smart TVs, game consoles (such as Xbox) and set-top boxes (such as Chromecast, Amazon Fire TV, etc.)
Desktop devices, including operating systems using laptops, such as Windows,mac OS X, Linux or Chrome OS
? tablet

? phablets, phone with a screen greater than 5.5
Smart phones, using a large operating system such as Android,ios, Windows or BlackBerry phones.
? Social devices: Firefox OS, Nokia Ashaos, Asha or feature phones, etc.
? wearable devices such as smart watches.

Mobile Hardware

The main metrics are as follows:

? CPU: Parsing, rendering and execution
? Memory : Dom tree, image cache and decompression data storage
? GPU: Some rendering operations (often referred to as hardware Acceleration )
? GPU Memory : image buffers and layer storage

The CPU speed of mobile devices is usually only 20% of desktop devices, and memory is usually only 30%.

Mobile network

Mobile networks are more unstable than Wi-Fi. The mobile network is not stable when switching. The main mobile network types are as follows:

? GPRS (2G)
? EDGE (2G, 2.5G or 3G)
? UMTS (3G)
? WCDMA (3G)
? TD-SCDMA (3G non-mainstream)
? HSPA (3G)
? EVDO (3G)
? hspa+ (3G or 4G)
? Mobile WiMax (4G)
? LTE (4G)
? Tdd-lte (4G non-mainstream)

According to https://gsmaintelligence.com/analysis data, the end of 2014, 2G 64%, 3G 30%, 4G 6%.
USA: 2G 20%, 3G 55%, 4G 25%. The http://www.4gamericas.org/index.cfm?fuseaction=page&pageid=2253 also provides similar data.

Speed of mobile network:

Note that for small data, it is not necessarily the larger the bandwidth the better.

Delay: Round Trip Time (RTT), because more mobile phone to the base station, the base station to the host network management process, usually quite large.

Mobile phones usually have a radio sleep mechanism to conserve energy, and a 3G wake-up connection may be 2.5s,4g within 100ms.

Mobile operating System

Mainstream: Ios,android

Second: BlackBerry, Windows,firefox OS, Tizen, Sailfish, Ubuntu

Again: Symbian, MeeGo, WebOS, Nokia Series 40, etc.
