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. [1] 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-G100 had been developed for use in other countries.

<span class="mw-page-title-main">Bluetooth</span> A short-range wireless technology standard

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft). It employs UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz. It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones.

A SIMcard is an integrated circuit (IC) intended to securely store an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephone devices. SIMs are also able to store address book contacts information, and may be protected using a PIN code to prevent unauthorized use.

Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less. NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smartphone. NFC communicating in one or both directions uses a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band, compliant with the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 848 kbit/s.

Network switching subsystem (NSS) is the component of a GSM system that carries out call out and mobility management functions for mobile phones roaming on the network of base stations. It is owned and deployed by mobile phone operators and allows mobile devices to communicate with each other and telephones in the wider public switched telephone network (PSTN). The architecture contains specific features and functions which are needed because the phones are not fixed in one location.

<span class="mw-page-title-main">Mobile phone feature</span> Mobile phone capability or application

A mobile phone feature is a capability, service, or application that a mobile phone offers to its users. Mobile phones are often referred to as feature phones, and offer basic telephony. Handsets with more advanced computing ability through the use of native code try to differentiate their own products by implementing additional functions to make them more attractive to consumers. This has led to great innovation in mobile phone development over the past 20 years.

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.

The switch terminal has a fixing portion received in the first hole and a contacting portion received in the second hole, the contacting portion forms an arced surface, the top of the arced surface is inserted into the second hole and protrudes above the top surface of the housing base in the receiving cavity.

<span class="mw-page-title-main">Mobile phone</span> Portable device to make telephone calls using a radio link

A mobile phone or cell phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture, and therefore mobile telephones are called cellphones in North America. In addition to telephony, digital mobile phones support a variety of other services, such as text messaging, multimedia messaging, email, Internet access, short-range wireless communications, satellite access, business applications, payments, multimedia playback and streaming, digital photography, and video games. Mobile phones offering only basic capabilities are known as feature phones ; mobile phones that offer greatly advanced computing capabilities are referred to as smartphones.
