Mobile Phone

Mobile VoIP is the application of Voice over IP technology to mobile handsets.

There are several methodologies by which a mobile handset can be integrated into a VoIP network. One implementation turns the mobile device into a standard SIP client, which then uses a data network to send and receive SIP messaging, and to send and receive RTP for the voice path. This methodology of turning a mobile handset into a standard SIP client requires that the mobile handset support, at minimum, high speed IP communications. In this application, standard VoIP protocols (typically SIP) are used over any broadband IP-capable wireless network connection such as EVDO rev A (which is synchronously high speed - both high speed up and down), HSDPA, WiFi or WiMAX.

Another implementation of mobile integration uses a softswitch like gateway to bridge SIP and RTP into the mobile network’s SS7 infrastructure. In this implementation, the mobile handset continues to operate as it always has (as a GSM or CDMA based device), but now it can be controlled by a SIP application server which can now provide advanced SIP based services to it. Several vendors offer this kind of capability today, including Tango Networks, Outsmart, NewStep, BridgePort and BroadSoft.

Mobile VoIP will require a compromise between economy and mobility. For example, Voice over Wi-Fi offers potentially free service but is only available within the coverage area of a Wi-Fi Access Point. High speed services from mobile operators using EVDO rev A or HSDPA may have better audio quality and capabilities for metropolitan-wide coverage including fast handoffs among mobile base stations, yet it will cost more than the typical Wi-Fi-based VoIP service.

Mobile VoIP will become an important service in the coming years as device manufacturers exploit more powerful processors and less costly memory to meet user needs for ever-more ‘power in their pocket’. Smartphones in mid-2006 are capable of sending and receiving email, browsing the web (albeit at low rates) and in some cases allowing a user to watch TV.

The challenge for the mobile operator industry is to deliver the benefits and innovations of IP without losing control of the network service. Users like the Internet to be free and high speed without extra charges for visiting specific sites. Such a service challenges the most valuable service in the telecommunications industry - voice - and threatens to change the nature of the global communications industry.

Mobile dating services, also known as cell dating, cellular dating,or cell phone dating, allow individuals to chat, meet, and possibly become romantically involved by means of text messaging, mobile chatting, and the web.These services allow their users to provide information about themselves in a short profile which is stored in their phones as a dating ID. They can then search for other IDs online or by calling a certain phone number dictated by the service. The criteria include age, gender and sexual preference. Usually these sites are free to use but standard text messaging fees may still apply as well as a small fee the dating service charges per message.Mobile dating websites, in order to increase the opportunities for meeting, focus attention on users that share the same social network and proximity. Some companies even offer services such as homing devices to alert users when another user is within thirty feet of one another.Some systems involve bluetooth technology to connect users in locations such as bars and clubs. This is known as proximity dating. These systems are actually more popular in some countries in Europe and Asia than online dating.Mobile dating, or text dating websites are gaining popularity - one of the leaders in location based mobile dating is MeetMoi, http://www.meetmoi.com. According to The San Francisco Chronicle in 2005, “Mobile dating is the next big leap in online socializing.”[1] More than 3.6 million cell phone users logged into mobile dating sites in March 2007,  with most users falling in the under 35 age range.Some experts believe that the rise in mobile dating is due to the growing popularity of online dating. Analyst Brent Iadarola of Frost & Sullivan said, “I think people are more comfortable with online dating, and it’s generally been accepted, the comfort people have with online dating in the wired world is now translating to the mobile world.”Others believe it is all about choice, as Joe Brennan Jr., vice president of Webdate says, “It’s about giving people a choice. They don’t have to date on their computer. They can date on their handset, it’s all about letting people decide what path is best for them.”

The mobile phone or mobile, also called a wireless, cellular phone, cell phone (AKA: cellphone), cell or hand phone (HP), is a long-range, portable electronic device used for mobile communication that uses a network of specialized base stations known as cell sites. In addition to the standard voice function of a telephone, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, and MMS for sending and receiving photos and video. Most current mobile phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones).
