The International Telecommunications Union defines 3G standards for wireless communication devices, including wireless calls and data transfer. The 3G standard guarantees a specific volume capacity and transmission speed. The first 3G network was implemented in Japan in 2001, and WiMAX technology provides “last mile” transmission to the end user. The 3G standard enables faster and more reliable wireless data services, but critics point out inconsistencies in data flow and multiple international identifications for the standards. Future work on 4G and other new systems will likely clarify the parameters of telecommunications standards.
A 3G standard is a specific standard for telecommunication equipment and systems. A group called the International Telecommunications Union defines these sets of standards and what they offer to the mobile telecommunications community. The International Telecommunications Union or ITU was founded as the International Telegraph Union in 1865 and still plays a leading role in the development of international standards as part of the infrastructure of the United Nations.
The types of communications covered by this type of telecommunications standard include wireless telephone calls and wireless data transfer. Palm devices that provide Internet access are also based on the same telecommunication standards. A 3G standard guarantees a specific volume capacity for these systems, as well as transmission speeds and other aspects of operational use.
Part of the 3G standard is for a transmission speed. The 3G standard offers 14 megabits per second uplink and 5.8 megabits downlink. A megabit, as a unit of data transmission, is equal to one million bits. Uplink and downlink are terms for satellite based broadcasting. Uplink is a signal that goes from the ground to a satellite and downlink is a signal that goes to the end user.
3G standards for wireless telecommunications are a twenty-first century invention. The first 3G network was implemented in Japan in 2001. Since then, several US telecommunications companies have implemented 3G technology, before switching to standard 4G services.
A common type of 3G service is WiMAX. WiMAX technology provides “last mile” transmission to the end user. When used in this context, “last mile” can actually refer to longer distances, where the WiMAX service receives a signal from the last closest point of wired transmission.
In practice, the standard 3G service offers more to users than wireless communication devices. Types of services that were previously not feasible are now commonplace with faster and more reliable wireless data services. These include mobile TV, video conferencing and other services that rely on huge amounts of data transmission.
Although a 3G standard provides a specific rate of transmission information as mentioned above, critics point out that due to factors in practical application, users cannot always be sure of a constant rate of data flow. Consumer groups are looking into how the ITU and related groups are promoting consistency with the 3G standard. Other critics of the 3G standard point out that multiple international identifications for the standards have created something of a “mixed” standard, including CDMA and US-based UMTS, the prevailing system for the European and Japanese markets. Future work on 4G and other new systems will most likely include more definition to clarify the parameters of a telecommunications standard.
