The second major technology component of mobile phones is known as Global System for Mobile Communications (GSM). This system was originally designed to work with analog voice signals, but today it can handle both digital phone calls and SMS messages.

The reason this now-classic technology is so popular is because it offers users low cost of ownership and simple hands free use.

By avoiding expensive smartphone fees, you have higher budget money to spend elsewhere!

There are three main parts to talk about in this article: how GSM works, some history, and types of GSM devices.

UMTS network architecture

The second major generation of Global System for Mobile Communications (GSM) technology is called Universal Mobile Telecommunications Service or, more commonly known as 3G mobile networks. These next-generation networks use what are referred to as third-generation technologies which include voice, data and video services over cellular telephone frequencies.

The most common type of 3G mobile service is often referred to as LTE, short for Long Term Evolution. This is due to its similarity in concept to another popular wireless communication standard named IEEE 802.16 or WiMAX. Both have evolved from initial standards developed by organizations such as the International Telecommunication Union – ITU–and the Electronics Industry Association – EIA.

WiMAX was an early contender to become the de facto fourth generation wireless technology but failed to gain widespread acceptance. It is now largely replaced by LTE although some regions still use it. Like WiFi, LTE operates in unlicensed bands at relatively high power levels which means anyone can use them without paying licensing fees.

LTE network architecture

The mobile technology that is most popular these days is called LTE or Long Term Evolution. This is an example of how cellular networks work. Networks like Verizon’s Fios, AT&T’s Mobile, T-Mobile, and Sprint’s BISPA are all built using similar technology!

LTE was designed to be much faster than previous generations. It uses many more radio frequencies, which allows it to use less power per bit sent and received. This creates better performance for users browsing websites, streaming videos, and other data intensive activities.

However, just because something is newer does not make it any better. Technology will eventually become outdated as things heretofore considered standard are replaced by ones that are potentially harmful to people or the environment.

GSM, one of the predecessors to LTE, has been around since 1997! That means it is in its twilight years. As such, there have been efforts to create a new globally compatible wireless communication protocol that is optimized for speed. These protocols are incompatible with older generation devices so they cannot be used to connect to current LTE networks.

This article will discuss some differences between GSM and LTE network architectures, what factors contribute to slower connection speeds, and strategies to improve your cell phone signal strength.

Phone calls

The next most important feature of smartphone technology is probably what we refer to as voice call functionality. Most modern cellphones have this built in, or at least accessible. This is very valuable as there are often times when you will not be connected to Wi-Fi or another source for internet, but you still want to make a phone call!

Voice calls over mobile networks are typically performed using a process called Voice Over Internet Protocol (or VOIP for short). Using software and protocols that were designed primarily for use over traditional landline phones, VOIP allows phone calls to be made over wifi or even through other apps like WhatsApp.

Some features such as speaker modes can be limited by your cellular data plan so it’s best to keep an eye on these.

Location based services

Another feature that most people use their phones for is to access location-based services (LBS). These apps use your phone’s GPS or cell tower position to determine where you are, and then offer you different features depending on this information.

For example, some may tell you how far away you are from home if you decide to make an early exit after work. Others will alert you when you reach your destination, and many even provide turn by turn navigation!

By adding these services onto your smartphone, they become more useful than ever before. Fortunately, there are several good options available in the market today. You just need to pick one that fits your needs and preferences best.
