Personal Handy-phone System
The Personal Handy-phone System (PHS), also marketed as the Personal Communication Telephone (PCT) in Thailand, and the Personal Access System (PAS) and commercially branded as ''Xiaolingtong'' () in Mainland China, was a mobile network system operating in the 1880–1930 MHz frequency band, used mainly in Japan, China, Taiwan, and some other Asian countries and regions. Outline Technology PHS is essentially a cordless telephone A cordless telephone or portable telephone has a portable telephone handset that connects by radio to a base station connected to the public telephone network. The operational range is limited, usually to the same building or within some short ... like Digital Enhanced Cordless Telecommunications, DECT, with the capability to handoff, handover from one cellular network, cell to another. PHS cells are small, with transmission power of base station a maximum of 500 mW and range typically measures in tens or at most hundreds of metres (some ...

W-SIM
W-SIM（RX420AL） W-SIM (Willcom-SIM) is a SIM card developed by Willcom which, in addition to standard SIM functions, also has the core components of a cellular telephone ( PHS), such as the radio receiver/transmitter, built inside. It is currently used in some terminals (listed below), which do not have radio modules. The W-SIM core module is an extended version of a SIM card, containing not only user data but also all the transmission technology needed for a mobile device to work. A terminal device developer can build a customized terminal without the design and development of a radio module, and users can change to a different radio module W-SIM without changing the terminal itself. Similar to traditional handsets made by WILLCOM, W-SIM terminals can be used in Japan, including global roaming with Taiwan and Thailand. For Mainland China, China Netcom had W-SIMs available, though its PHS network is due to be phased out this year. In addition, a GSM version called the CM-G10 ...

Au (mobile Phone Operator)
au, or au by KDDI, is a Japanese mobile phone operator. au is a brand marketed by KDDI in the main islands of Japan and by Okinawa Cellular in Okinawa for their mobile cellular services. au is the second-largest wireless carrier in Japan, with 60.398 million subscribers as of March 2021. Naming According to the brand creator, the name 'au' is based on the Japanese verbs for 'meet' (会う) and 'unite' (合う) (both pronounced 'au'). However, KDDI explains that au comes from two letters which stand for few words. 'A' is for access, always and amenity, and 'U' is for unique, universal and user.

DDI's network was run by independent phone companies, and began service ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DC-HSPA+
Evolved High Speed Packet Access, HSPA+, HSPA (Plus) or HSPAP, is a technical standard for wireless broadband telecommunication. It is the second phase of HSPA which has been introduced in 3GPP release 7 and being further improved in later 3GPP releases. HSPA+ can achieve data rates of up to 42.2 Mbit/s. It introduces antenna array technologies such as beamforming and multiple-input multiple-output communications (MIMO). Beam forming focuses the transmitted power of an antenna in a beam towards the user's direction. MIMO uses multiple antennas at the sending and receiving side. Further releases of the standard have introduced dual carrier operation, i.e. the simultaneous use of two 5 MHz carriers. HSPA+ is an evolution of HSPA that upgrades the existing 3G network and provides a method for telecom operators to migrate towards 4G speeds that are more comparable to the initially available speeds of newer LTE networks without deploying a new radio interface. HSPA+ should n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3GPP Long Term Evolution
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is also called 3.95G and has been marketed as "4G LTE" and "Advanced 4G"; but it does not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. The requirements were set forth by the ITU-R organisation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
