The common standards complying with the IMT2000/3G standard are: While the GSM EDGE standard ("2.9G"), DECT cordless phones and Mobile WiMAX standards formally also fulfill the IMT-2000 requirements and are approved as 3G standards by ITU, these are typically not branded as 3G and are based on completely different technologies. The 3G systems and radio interfaces are based on spread spectrum radio transmission technology. B offers peak rates of 14.7 Mbit/s downstream. The cell phones are typically CDMA2000 and IS-95 hybrids. The CDMA2000 system, first offered in 2002, standardized by 3GPP2, used especially in North America and South Korea, sharing infrastructure with the IS-95 2G standard.The latest UMTS release, HSPA+, can provide peak data rates up to 56 Mbit/s in the downlink in theory (28 Mbit/s in existing services) and 22 Mbit/s in the uplink.The TD-SCDMA radio interface was commercialized in 2009 and only offered in China.The original and most widespread radio interface is called W-CDMA (Wideband Code Division Multiple Access).Several radio interfaces are offered, sharing the same infrastructure: The cell phones are typically UMTS and GSM hybrids. The UMTS (Universal Mobile Telecommunications System) system, standardized by 3GPP in 2001, was used in Europe, Japan, China (with a different radio interface) and other regions predominated by GSM (Global Systems for Mobile) 2G system infrastructure.Subsequent 3G releases, denoted 3.5G and 3.75G, provided mobile broadband access of several Mbit/s for smartphones and mobile modems in laptop computers. However, many services advertised as 3G provide higher speed than the minimum technical requirements for a 3G service. To meet the IMT-2000 standards, a system must provide peak data rates of at least 144 kbit/s. Services advertised as 3G are required to meet IMT-2000 technical standards, including standards for reliability and speed (data transfer rates). However, 3G services have largely been supplanted in marketing by 4G and 5G services in most areas of the world. Several telecommunications companies marketed wireless mobile Internet services as 3G, indicating that the advertised service was provided over a 3G wireless network. The first commercial 3G networks were introduced in mid-2001. Each generation is characterized by new frequency bands, higher data rates and non–backward-compatible transmission technology. This ensures it can be applied to wireless voice calls, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies.Ī new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s. Later 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. ģG telecommunication networks support services that provide an information transfer rate of at least 144 kbit/s. 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV. This network is based on a set of standards used for mobile devices and mobile telecommunications use services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the International Telecommunication Union. This network was superseded by 4G, and later on by 5G. It is the upgrade over 2G, 2.5G, GPRS and 2.75G Enhanced Data Rates for GSM Evolution networks, offering faster data transfer, and better voice quality. To contact Phoenix Contact about Phoenix Contact Security router with 3G mobile phone interface use Get a quote.3G is the third generation of wireless mobile telecommunications technology. Thanks to the new mGuard security routers with integrated mobile phone interface, a high-performance system for secure remote communication is now available. Internet and VPN based solutions therefore replace modem dial-up connections and pose new challenges for products: the transmission of large amounts of data, high transmission speeds, and protection against unauthorized access must also be guaranteed. ![]() Industrial telecommunication products are key components within remote control and maintenance solutions. They function as a replaceable configuration memory for fast startup and easy device replacement. Furthermore, SD memory cards are supported. In addition, the new devices offer an integrated 4-port switch - in the most sophisticated design, this is a Managed Switch. The products have a robust metal housing, two SIM card slots, a GPS receiver, and support two or ten VPN tunnels, depending on their design. American CDMA mobile phone networks are now supported in addition to UMTS/HASPA. Integrated security technologies such as VPN and firewall offer the optimum solution here.
