Remote call forwarding
In telecommunication, a remote call forwarding is a service feature that allows calls coming to a remote call-forwarding number to be automatically forwarded to any answering location designated by the call receiver.
Customers may have a remote-forwarding telephone number in a central switching office without having any other local telephone service in that office.

SoftPhone
(SOFTware PHONE) A software-based phone for voice over IP (VoIP) that is installed in the user's PC. The audio interface can be a microphone and speakers plugged into the sound card, although a headset is preferred. For better clarity, a USB phone or Bluetooth phone can be used.
Softphones can work as stand-alone phones or be part of an IP PBX family. They offer the full range of phone features, such as call forwarding and conference calling, and also provide integration with applications such as Outlook for automatic phone dialing.
The first VoIP softphone was VocalTec's Internet Phone, which was introduced in 1995 (see Internet Phone). See VoIP, IP phone, IP PBX and IP telephony. See also software defined radio.

Mobile phone features
There are significant questions as to who first invented the camera phone, as numerous other people received patents filed in the early 1990s for the device, including David M. Britz of AT&T Research in March of 1994 and Phillipe Kahn, who claims to have first invented it in 1997.[citation needed] The camera phone now holds 85% of the mobile phone market[citation needed]. Mobile phones often have features beyond sending text messages and making voice calls, including Internet browsing, music (MP3) playback, memo recording, personal organizer functions, e-mail, instant messaging, built-in cameras and camcorders, ringtones, games, radio, Push-to-Talk (PTT), infrared and Bluetooth connectivity, call registers, ability to watch streaming video or download video for later viewing, video calling and serve as a wireless modem for a PC, and soon will also serve as a console of sorts to online games and other high quality games (e.g. Final Fantasy Agito).[citation needed]
When cellular telecoms services were launched, phones and calls were very expensive and early mobile operators (carriers) decided to charge for all air time consumed by the mobile phone user. This resulted in the concept of charging callers for outbound calls and also for receiving calls. As mobile phone call charges diminished and phone adoption rates skyrocketed, more modern operators decided not to charge for incoming calls. Thus some markets have "Receiving Party Pays" models, in which both outbound and received calls are charged, and other markets have "Calling Party Pays" models, by which only making calls produces costs, and receiving calls is free. An exception to this is international roaming, by which also receiving calls is normally also charged.[citation needed]
The European market adopted a "Calling Party Pays" model throughout the GSM environment and soon various other GSM markets also started to emulate this model. As Receiving Party Pays systems have the undesired effect of phone owners keeping their phones turned off to avoid receiving unwanted calls, the total voice usage rates (and profits) in Calling Party Pays countries outperform those in Receiving Party Pays countries. Consequently, most countries previously with Receiving Party Pays models have either abandoned them or employed alternative marketing methods, such as massive voice call buckets, to avoid the problem of phone users keeping phones turned off.

Mobile Phone Technology
Mobile phones and the network they operate under vary significantly from provider to provider, and country to country. However, all of them communicate through electromagnetic radio waves with a cell site base station, the antennas of which are usually mounted on a tower, pole or building.
The phones have a low-power transceiver that transmits voice and data to the nearest cell sites, usually not more than 8 to 13 km (approximately 5 to 8 miles) away. When the mobile phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its unique identifiers, and will then be alerted by the mobile switch when there is an incoming telephone call. The handset constantly listens for the strongest signal being received from the surrounding base stations. As the user moves around the network, the mobile device will "handoff" to various cell sites during calls, or while waiting (idle) between calls it will reselect cell sites.
Cell sites have relatively low-power (often only one or two watts) radio transmitters which broadcast their presence and relay communications between the mobile handsets and the switch. The switch in turn connects the call to another subscriber of the same wireless service provider or to the public telephone network, which includes the networks of other wireless carriers. Many of these sites are camouflaged to blend with existing environments, particularly in scenic areas.
The dialogue between the handset and the cell site is a stream of digital data that includes digitized audio (except for the first generation analog networks). The technology that achieves this depends on the system which the mobile phone operator has adopted. The technologies are grouped by generation. The first-generation systems started in 1979 with Japan, are all analog and include AMPS and NMT. Second-generation systems, started in 1991 in Finland, are all digital and include GSM, CDMA and TDMA. Third-generation networks, which are still being deployed, started with Japan in 2001, are all digital, and offer high-speed data access in addition to voice services and include WCDMA (known also as UMTS), and CDMA2000 EV-DO. China will launch a third 3G technlogy on the TD-SCDMA standard. Each network operator has a unique radio frequency band.

Choosing and Using Credit Cards
Chances are you've gotten your share of "pre-approved" credit card offers in the mail, some with low introductory rates and other perks. Many of these solicitations urge you to accept "before the offer expires." Before you accept, shop around to get the best deal.
Credit Card Terms
A credit card is a form of borrowing that often involves charges. Credit terms and conditions affect your overall cost. So it's wise to compare terms and fees before you agree to open a credit or charge card account. The following are some important terms to consider that generally must be disclosed in credit card applications or in solicitations that require no application. You also may want to ask about these terms when you're shopping for a card.
Annual Percentage Rate. The APR is a measure of the cost of credit, expressed as a yearly rate. It also must be disclosed before you become obligated on the account and on your account statements.
The card issuer also must disclose the "periodic rate" - the rate applied to your outstanding balance to figure the finance charge for each billing period.
Some credit card plans allow the issuer to change your APR when interest rates or other economic indicators - called indexes - change. Because the rate change is linked to the index's performance, these plans are called "variable rate" programs. Rate changes raise or lower the finance charge on your account. If you're considering a variable rate card, the issuer must also provide various information that discloses to you:
- that the rate may change; and
- how the rate is determined - which index is used and what additional amount, the "margin," is added to determine your new rate.
At the latest, you also must receive information, before you become obligated on the account, about any limitations on how much and how often your rate may change.
Free Period. Also called a "grace period," a free period lets you avoid finance charges by paying your balance in full before the due date. Knowing whether a card gives you a free period is especially important if you plan to pay your account in full each month. Without a free period, the card issuer may impose a finance charge from the date you use your card or from the date each transaction is posted to your account. If your card includes a free period, the issuer must mail your bill at least 14 days before the due date so you'll have enough time to pay.
Annual Fees. Most issuers charge annual membership or participation fees. They often range from $25 to $50, sometimes up to $100; "gold" or "platinum" cards often charge up to $75 and sometimes up to several hundred dollars.
Transaction Fees and Other Charges. A card may include other costs. Some issuers charge a fee if you use the card to get a cash advance, make a late payment, or exceed your credit limit. Some charge a monthly fee whether or not you use the card.
Balance Computation Method for the Finance Charge. If you don't have a free period, or if you expect to pay for purchases over time, it's important to know what method the issuer uses to calculate your finance charge. This can make a big difference in how much of a finance charge you'll pay - even if the APR and your buying patterns remain relatively constant. See page 4 for examples of how the methods can affect your costs.

Human health impacts
Since the introduction of mobile phones, concerns have been raised about the potential health impacts from regular use.[25] As mobile phone penetrations grew past fixed landline penetration levels in 1998 in Finland and from 1999 in Sweden, Denmark and Norway, the Scandinavian health authorities have run continuous long term studies of effects of mobile phone radiation effects to humans, and in particular children. Numerous studies have reported and most studies consistently report no significant relationship between mobile phone use and health. Studies from the Institute of Cancer Research, National Cancer Institute and researchers at the Danish Institute of Cancer Epidemiology in Copenhagen for example showed no link between mobile phone use and cancer.[26][27] The Danish study only covered analog mobile phone usage up through 1995, and subjects who started mobile phone usage after 1995 were counted as non-users in the study.[28] The health concerns have grown as mobile phone penetration rates throughout Europe reached 80%–90% levels earlier in this decade and prolonged exposure studies have been carried out in almost all European countries again most reporting no effect, and the most alarming studies only reporting a possible effect. However, a study by the International Agency for Research on Cancer of 4,500 users found a statistically significant link between tumor frequency and mobile phone use.[29]
The many links to cellphones and sperm quality of cause is a strong scientifically evidence that the radiation emitting from Mobile phones always should be considered as potentially dangerous, even if we don't know all the mechanism behind the already known dangers to living cells and organisms.

History of Mobile Phone
There is one U.S. patent, Patent Number 887357 for a wireless telephone, issued 1908 to Nathan B. Stubblefield of Murray, Kentucky. He applied this to "cave radio" telephones and not directly to cellular telephony as we know it today.[1] However, the introduction of cells for mobile phone base stations, invented in 1947 by Bell Labs engineers at AT&T, was further developed by Bell Labs during the 1960s. Radiophones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held cellular radio devices have been available since 1983. Due to their low establishment costs and rapid deployment, mobile phone networks have since spread rapidly throughout the world, outstripping the growth of fixed telephony.[citation needed]
In 1945, the zero generation (0G) of mobile telephones was introduced. 0G mobile telephones, such as Mobile Telephone Service, were not officially categorized as mobile phones, since they did not support the automatic change of channel frequency during calls, which allows the user to move from one cell (the base station coverage area) to another cell, a feature called "handover".[citation needed]
In 1984, Bell Labs invented such a "call handoff" feature, which allowed mobile-phone users to travel through several cells during the same conversation. Motorola is widely considered to be the inventor of the first practical mobile phone for handheld use in a non-vehicle setting. Using a modern, if somewhat heavy portable handset, Motorola manager Martin Cooper made the first call on a handheld mobile phone on April 3, 1973.[2]
The first commercial cellular network was launched in Japan by NTT in 1979. Fully automatic cellular networks were first introduced in the early to mid 1980s (the 1G generation) with the Nordic Mobile Telephone (NMT) system in 1981. This was followed by a boom in mobile telephone usage, particularly in Northern Europe.[citation needed]
The first "modern" network technology on digital 2G (second generation) cellular technology was launched by Radiolinja (now part of Elisa Group) in 1991 in Finland on the GSM standard which also marked the introduction of competition in mobile telecoms when Radiolinja challenged incumbent Telecom Finland (now part of TeliaSonera) who ran a 1G NMT network. A decade later, the first commercial launch of 3G (Third Generation) was again in Japan by NTT DoCoMo on the WCDMA standard.[citation needed] Until the early 1990s, most mobile phones were too large to be carried in a jacket pocket, so they were typically installed in vehicles as car phones. With the miniaturization of digital components, mobile phones have become increasingly handy over the years.

Other Costs and Features
Credit terms vary among issuers. When shopping for a card, think about how you plan to use it. If you expect to pay your bills in full each month, the annual fee and other charges may be more important than the periodic rate and the APR, if there is a grace period for purchases. However, if you use the cash advance feature, many cards do not permit a grace period for the amounts due - even if they have a grace period for purchases. So, it may still be wise to consider the APR and balance computation method. Also, if you plan to pay for purchases over time, the APR and the balance computation method are definitely major considerations.
You'll probably also want to consider if the credit limit is high enough, how widely the card is accepted, and the plan's services and features. For example, you may be interested in "affinity cards" - all-purpose credit cards sponsored by professional organizations, college alumni associations and some members of the travel industry. An affinity card issuer often donates a portion of the annual fees or charges to the sponsoring organization, or qualifies you for free travel or other bonuses.
Special Delinquency Rates. Some cards with low rates for on-time payments apply a very high APR if you are late a certain number of times in any specified time period. These rates sometimes exceed 20 percent. Information about delinquency rates should be disclosed to you in credit card applications or in solicitations that do not require an application.
telecommunications
cellular telephone or cellular radio, telecommunications system in which a portable or mobile radio transmitter and receiver, or “telephone,” is linked via microwave radio frequencies to base transmitter and receiver stations that connect the user to a conventional telephone network. The geographic region served by a cellular system is subdivided into areas called cells. Each cell has a central base station and two sets of assigned transmission frequencies; one set is used by the base station, and the other by mobile telephones. To prevent radio interference, each cell uses frequencies different from those used by its surrounding cells, but cells sufficiently distant from each other can use the same frequencies. When a mobile telephone leaves one cell and enters another, the telephone call is transferred from one base station and set of transmission frequencies to the next using a computerized switching system. The first cellular telephone system began operation in Tokyo in 1979, and the first U.S. system began operation in 1983 in Chicago. A camera phone is a cellular phone that also has picture taking capabilities. Some camera phones have the capability to send these photos to another cellular phone or computer. Advances in digital technology and microelectronics has led to the inclusion of unrelated applications in cellular telephones, such as alarm clocks, calculators, Internet browsers, and voice memos for recording short verbal reminders, while at the same time making such telephones vulnerable to certain software viruses. In many countries with inadequate wire-based telephone networks, cellular telephone systems have provided a means of more quickly establishing a national telecommunications network.

Receiving a Credit Card
Federal law prohibits issuers from sending you a card you didn't ask for. However, an issuer can send you a renewal or substitute card without your request. Issuers also may send you an application or a solicitation, or ask you by phone if you want a card - and, if you say yes, they may send you one.
