www.Primo.com: Did you Wi Fi Dual function.

Dual Mode.

Cellular Phone Dual Mode is a mobile phone that can use more than one network at a time to receive or transmit data. Dual mode can be categorized into three types, namely:

Network compatibility.

That is a mobile phone that can be used in two different systems, namely GSM and CDMA. Dual slot because it is equipped with two slots for SIM and RUIM cards (T4863).

Cellular radio and nonselular

The mobile phone can be used for telephone and can also be used for the connection WiFi or DECT (Digital Enhanced Cordless Telecommunications)

Telephone cables.

Telephone wires using VoIP and POTS technology. However, this type of phone as a router and modem requires special to make VoIP calls

Wi Fi.

(Wireless Fidelity) is a wireless connection such as mobile phones by using radio technology, so users can transfer data quickly and safely. Wi-Fi is not only can be used to access the Internet, Wi-Fi can also be used to create a wireless network in the company. Therefore many people associate with the Wi-Fi "Freedom" for Wi-Fi technology gives freedom to the user to access the internet or transfer data from the meeting room, hotel room, campus, and cafes are marked Wi-Fi Hot Spot. Also one of the advantages of Wi-Fi is practicality, no need to bother installing network cables. For the problem of speed depending on the signals obtained.
Wi-Fi can only be accessed with Wi-Fi certified equipment Radio such as computers, laptops, PDAs or cell phones. For the latest version of the laptop output in 2007, already there is Wi-Fi on board. If not available the user can install Wi-Fi PC Cards are shaped in a PCMCIA card slot contained in your laptop or USB Wi-Fi.
For PDAs, users can install the Compact Flash format Wi-Fi radios in slots you have available. For users whose computers or PDAs - is using Windows XP, simply by plugging the card into an available slot, Windows XP will automatically detect the area around you and look for a Wi-Fi network that is closest to you. It is very easy to find a sign of whether the device has Wi-Fi, namely by looking at the Wi-Fi CERTIFIED logo on the packaging. Although Wi-Fi is only accessible place marked with Wi-Fi Hotspot, the number of public places that offer Wi-Fi Hotspot increased drastically. This is because with maketh them as a Wi-Fi Hotspot means their customers can access the internet, which means providing added value for customers.
Wi-Fi service offered by each Hot Spot were diverse, there are offers for free access as well as in the executive lounge service, no customer requires the wearer to become one of the ISP that offers free Wi-Fi and there is also a card offers pre-paid. Whatever your choice for how to access the Wi-Fi, the most important is the presence of Wi-Fi, you can work anywhere and anytime that you do not need to be always cooped up in your workspace to complete each task.

DEVELOPMENT OF DUAL MODE Wi-Fi.

Market mobile phone (cell phone) or have the ability to dual mode GSM cellular network access and wireless Internet network Wi-Fi (wireless fidelity) continues to increase. Juniper Research projecting a dual-mode mobile phone market in 2012 reached US $ 68 billion.
Currently the demand for devices that can facilitate the activities of users to communicate over a network voice over Internet protocol (VoIP) from both the corporate and consumer continues to show growth

VoIP.

VoIP (Voice over Internet Protocol) is a technology miss the sound (voice) into the form of data packets over an IP network (Internet Protocol) is in the position of the layer 3, the network layer in the OSI model (Open Systems Interconnection). As for the IP network itself can be through many ways that can be via Wi-Fi hotspots, broadband cable network DSL (digital subscriber line), cable TV, Satellite and others.
It can be concluded that by using dual mode phone, then in addition to doing the talking on a cellular network, we can also do a VoIP conversation via Wi-Fi, or often referred to as VoWi-Fi (wireless fidelity voice over).

MOBILE CONVERGENCE APPLIANCE.

mobile convergence appliance (MCA) or convergence device moves. The device is based on the Linux operating system that can be used with mobile phones that can be programmed (also called smart phones).
When a user is in the office, the MCA will deliver incoming phone calls, either to phone or phone to the table. Because it is always constantly connected to the phone, the MCA can determine whether the phone can be reached via a Wi-Fi network. This means there are no additional fees charged.
If the users are on the road, the MCA will determine whether the phone can be reached by the nearest Wi-Fi hotspot or the call was delivered through a standard cellular network link. The reverse process is also applicable for calls from mobile communications equipment.
Meanwhile, missed calls will be forwarded by the MCA to the company voice mail system. DiVitas product is also fairly intelligent. He can constantly evaluate the quality of the connection. For example, if you are in a Starbucks using Wi-Fi hotspots are available, but the other guests sitting next to you are downloading video files from YouTube, measuring equipment degradation. If you can not, will be submitted to the cellular network.

FIXED MOBILE CONVERGENCE.

FMC (fixed mobile convergence) is a combination of two different technologies, namely mobile technology and Wi-Fi becomes a form of service that is integrated in a single device 'that is mobile. FMC Technologies promises a communication service for customers always on the move and keep activity.
It can simply be described as follows. Someone has a dual mode phone and subscribe to FMC services. One time in the morning before leaving for work, he received a phone call in the dual modes of superiors for a specific task.
FMC network will automatically distribute the call to the Wi-Fi broadband networks available at home. During the conversation, he walked to his car, and started driving his car out of the housing complex. At that time the FMC will seamlessly move the talks are still going to the cellular network without disruption or drop the call. When in the office, all communication through its dual mode phone will re-served by the Wi-Fi network in the office. FMC can be viewed from several types of which is the type of architecture that is based on UMA (unlicensed mobile access) and type based on SIP (session initiation protocol).
Type FMC UMA is a type of architecture that implements GSM tunneling technology passes Wi-Fi network where do encapsulation of the signaling and bearer of his. UMA models do not support the SIP protocol, so the MSC (mobile switching center) that there still can be maintained and is responsible for switching and call control. One operator that has been providing services FMC UMA is British Telecom.
FMC other type is based SIP protocol that is a model based on technology FMC IMS (IP multimedia subsystems) that standardization is done by 3GPP (The Third Generation Partnership Project). IMS is a next generation network (NGN) that can replace or exchange switch technology currently still based on circuit or TDM (time division multiplexing).
Mobile Switching Center (MSC) of the existing cellular network is maintained and IMS will work together with the MSC with the concept of roaming, so that one of the network will be the home network and the other will be a visited network. In 3G networks, where all the infrastructure is IP, then all the functions of MSC will be replaced by IMS.
Dual Mode Wi-Fi that was launched by the Chinese company combines Wi-Fi / WiMAX with GSM / CDMA / 3G (UMTS). The combination resulted in a phone conversation that will not be interrupted even if you are out of the Wi-Fi / WiMAX and entry into the mobile phone network (mobile phone).

HYBRID CELL PHONE.

Hybrid Cell phone is a cell phone (mobile phone) that is enabled with Wi-Fi, which is also capable of utilizing two communication systems, namely cellular or mobile and Wi-Fi networks. The development of dual-mode phones will increase and attract more people to use it. Because, with the more mature technology, the user will have the opportunity to communicate without boundaries and more economical, because enough with the same phone, you are enabled to communicate in many places with ease.
When at home, with the same phone, you can connect to a home Wi-Fi network or later VoIP phone service broadband. When out of the house and into the car, then all the way you can still communicate rely on mobile networks (GSM / CDMA). Once in office, your phone will automatically go to a Wi-Fi VoIP LAN or office. Not only are you uninterrupted communications, even if you move from one network to another, your communications are also increasingly easy and economical.
Mobile technology like this will be a transitional solution to a Wi-Fi network that produces high-quality communication, either in the home or office building, which is very difficult to get when you are on the outside by using a cellular network. In addition, it will also provide the speed of surfing the web on your smartphone. Thank you for reading this article.
