3G is the abbreviation for third-generation technology, and the term is often used when describing mobile phone standards. 3G services provide users the ability to transfer voice data like a phone calls and non-voice data like downloading, emailing, or instant messaging. Video telephony is also a large part of what 3G technology is known for.
3G technology is called third generation technology because of the previous technology names: digital/PCS generation (2G) and analog cellular technology (1G). The 3G technological development was to establish a true multimedia cell phone. These are known as smartphones. They feature increased bandwidth and transfer rates. These faster transfer rates and bandwidth accommodate phone based audio, video files, and web-based applications.
3G is made up of several cellular technologies. Three of the most common technologies are:
• CDMA2000. Based on 2G Code Division Multiple Access.
• WCDMA (UMTS). Wideband Code Division Multiple Access.
• TD-SCDMA. Time-division Synchronous Code-division Multiple Access.
Third generation networks have transfer speeds that can potentially reach speeds of up to 3 Mbps. This means it takes around 15 seconds to download a three minute MP3 song. For a quick comparison: the faster of the 2G phones on the
market achieve up to 144Kpbs. It takes around eight minutes to download the same three minute MP3 song. The 3G’s data transfer rate is much more ideal for downloading information from the Internet. It is also much better for sending
and receiving large multimedia files. A 3G cell phone is like a mini-laptop. It can handle broadband applications. The most common applications are video conferencing, streaming web video, sending and receiving faxes, and instantly
downloading email messages complete with attachments.
The 3G standard is well known because it was the cause of a massive expansion of mobile communications around the world. It was one of the most incredible advances in consumer mobile phone technology. The most notable development was during the introduction of the smartphone mentioned above. This includes the popular iPhone and the Android brand product family. These devices combined the mobile phone with the abilities and technology of the PDA. These technological advancements lead to a widespread demand for mobile internet connectivity. 3G technology also introduced the buzzword “mobile broadband”. This is because of its capabilities and speed. It makes it a solid alternative for browsing the internet. It is also become quite common for cell phones with 3G technology to be utilized by computers for connecting to 3G networks.
