Wireless Village

Wireless Village is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wireless Village rather than just read about it. In short: Wireless Village is a set of specifications for mobile instant messaging and presence services. It is intended to be a standard for cellphones and mobile devices to use these services across platforms.

Key takeaways

Wireless Village belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Wireless Village to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wireless Village from memory before moving on to harder problems.

Reference excerpt

Wireless Village is a set of specifications for mobile instant messaging and presence services. It is intended to be a standard for cellphones and mobile devices to use these services across platforms. Many wireless phones now include mobile instant messaging capabilities designed to hook into messaging services using IMPS on a carrier's network, formerly known as the Wireless Village protocol. Those phones implement it as an IM icon on the phone, which is typically renamed and customized by the cellphone carrier or removed completely if not supported at the network level. Most Nokia and Motorola phones have that feature, as do many Sony Ericsson phones. Wireless Village has recently consolidated into the Open Mobile Alliance (OMA) and no longer exists as an independent organization.

Description The white paper describes the service: "Where possible, the protocol makes use of existing Internet and Web technologies. These technologies are implemented widely and are well tested, so their use within the protocol ensure easy implementation and interoperability testing. XML, the Extensible Markup Language, is rapidly emerging as the lingua franca for representing structured data over the Web. To the extent possible, the protocol uses XML to represent the protocol data being exchanged during an IMPS session. IMPS activities in the IETF IMPP have received widespread interest throughout the industry. Although it is still in development, to the extent possible, the Wireless Village initiative will support the CPIM draft and build upon it. Other useful standards in this space include the Multipurpose Internet Mail Extensions (MIME) for registering the format of the IMPS protocol messages."

History An announcement was made when this service was conceived by Ericsson, Motorola and Nokia. The specification is maintained by the Open Mobile Alliance, and is currently at version 1.3 of the protocol. As of now, only a few public services exist using Wireless Village. Any unlocked phone can be configured to use these services, and therefore connect to other instant messaging services if implemented.

Yamigo Yamigo was a free communications service, based in Finland, that allowed instant messaging on mobile phones over wireless data services such as GPRS. The service was based on the protocol Wireless Village, developed by the Open Mobile Alliance, which is a joint venture between Nokia, Sony Ericsson, Motorola and other mobile device manufacturers. Certain models of mobile phones that include a chat client could access the Yamigo network. These included certain models of phones from Nokia, Motorola, Sony Ericsson and Siemens. Once registered, Yamigo users could send messages to each other, and to users on Yahoo! Messenger, MSN Messenger, AOL Instant Messenger and ICQ. Yamigo supported importing contact lists from those services automatically. Users connected to Yamigo via WAP and the internet. On the service's sign up page, users selected how frequently their phone polled the Yamigo network. Because it is a client-server protocol, receiving messages depended on how often the phone was set to poll the network. The service was abandoned in late 2005, and the last upgrade was version .19 in April 2005.

Worked examples

Example 1 — a first encounter with Wireless Village

Start with the simplest possible case. Write down what Wireless Village claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wireless Village before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wireless Village ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wireless Village

In research: Wireless Village appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Wireless Village in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Wireless Village is common in secondary-school and first-year university syllabi. It links to neighbouring topics Instant messaging protocols, Mobile telecommunications standards, Open Mobile Alliance standards, so understanding it makes those chapters shorter.
In everyday life: Look for Wireless Village outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
