What is GSM?

 The ubiquity of the GSM standard makes it increasingly common for users to roam internationally after signing a "roaming agreement" between mobile phone operators. The biggest difference between GSM and its previous standards is that its signaling and voice channels are digital, so GSM is considered a second generation (2G) mobile phone system. This shows that digital communication has been built into the system from a very early age. GSM is an open standard currently developed by 3GPP. So what network is gsm?

Regarding the network problem of gsm, GSM is the second generation of mobile communication technology. Its development goal is to enable a global mobile phone network standard to be used around the world, allowing users to use a mobile phone to travel all over the world. At present, China Mobile and China Unicom each have a GSM network, which is the world's largest mobile communication network. The GSM system includes several frequency bands such as GSM 900:900 MHz, GSM 1800:1800 MHz, and GSM1900:1900 MHz.

　　The GSM system has several important features: excellent anti-theft copying capability, large network capacity, rich mobile phone number resources, clear calls, strong stability and uncomfortable interference, sensitive information, less dead ends, and low power consumption of mobile phones.

Regarding the question of what network gsm is, the following will provide a detailed answer. From the user's point of view, the main advantage of GSM is that users can choose between higher digital voice quality and lower cost [SMS]. The advantage of network operators is that they can customize their device configurations to different customers, as GSM provides easier interoperability as an open standard. In this way, the standard allows network operators to provide roaming services, and users can use their mobile phones globally.

Frequency distribution

　　GSM900: Uplink (MHz) 890-915; Downstream (MHz) 935-960

　　GSM900E: Uplink (MHz) 880-915; Downstream (MHz) 925-960

　　GSM1800: Uplink (MHz) 1710-1785; Downstream (MHz) 1805-1880

　　GSM1900: Uplink (MHz) 1850-1910; Downstream (MHz) 1930-1990

　Gsm is a summary of what the network is. GSM is currently the most widely used mobile phone standard. More than 1 billion people in more than 200 countries and regions around the world are using GSM phones. All users can roam freely between mobile phone operators who have signed a "roaming agreement". The biggest difference between GSM and its previous standards is that its signaling and voice channels are digital, so GSM is considered a second generation (2G) mobile phone system. This shows that digital communication has been built into the system from a very early age. GSM is an open standard currently developed by 3GPP.

What is GSM? As a standard for continued development, GSM remains backward compatible with the original GSM phone. For example, the message exchange capability was added in the Release '97 version of the standard, which is GPRS. High-speed data exchange was also introduced in the Release '99 version of the standard, mainly EDGE and UMTS standards.

　　Editor's Note: As one of the many network standards, by 2004, more than 1 billion people worldwide used GSM phones, and GSM phones accounted for 70% of the global mobile phone market. This ratio is still relatively large. But with the emergence and popularity of 3G, the future of GSM is worrying. To learn more about what network gsm is, you can continue to pay attention to the latest developments in mobile technology.
