3G的简单定义
3G是英文3rd Generation的缩写，指第三代移动通信技术。相对第一代模拟制式手机(1G)和第二代GSM、TDMA等数字手机(2G)，第三代手机一般地讲，是指将无线通信与国际互联网等多媒体通信结合的新一代移 动通信系统。它能够处理图像、音乐、视频流等多种媒体形式，提供包括网页浏览、电话会议、电子商务等多种信息服务。为了提供这种服务，无线网络必须能够支持不同的数据传输速度，也就是说在室内、室外和行车的环境中能够分别支持至少2Mbps(兆字节/每秒)、384kbps(千字节/每秒)以及144kbps的传输速度。
三项技术标准：
W-CDMA：英文名称是Wideband CDMA，中文译名为“宽带分码多工存取”，它可支持384Kbps到2Mbps不等的数据传输速率，支持者主要以GSM系统为主的欧洲厂商。 CDMA2000：亦称CDMA Multi-Carrier，由美国高通北美公司为主导提出，摩托罗拉、Lucent和后来加入的韩国三星都有参与，韩国现在成为该标准的主导者。
TD-SCDMA：该标准是由中国大陆独自制定的3G标准，由于中国的庞大的市场，该标准受到各大主要电信设备厂商的重视，全球一半以上的设备厂商都宣布可以支持TD-SCDMA标准。
Push To Talk
Push To Talk
Last two days i was started using Push to Talk services powered by Maxis.Is fun! Our whole company are using this services to communicate.
It's save! Bacause i only have to pay RM15.00 each line per month, then i can enjoy unlimited usage for the whole month!
Try it out. You will enjou it.
Conventional two-way radios
For commercial, family and amateur two-way radios, PTT is a button that is pressed when needing to transmit with the radio on the tuned frequency or channel. While the PTT button remains unpressed (or unkeyed), any radio traffic that is received on the selected channel or frequency is heard through the radio's speaker. Unless the radio supports full-duplex operation, received audio is usually muted while the PTT button is pressed. Simultaneous full-duplex transmission and reception on a radio is generally not supported unless either the transmit and receive frequencies have significant separation between the two frequencies, or two different antennas are used with enough distance between them, or a cavity filter is used, due to an effect known as desensing which cancels out received transmissions.
More recently, the PTT concept has been adopted by cellphone carriers as a way to instantaneously send transmissions to other users on the system, emulating walkie-talkie communications on a mobile phone network.
Current use in mobile telephony (PTT PoC)
PTT PoC or Push to Talk over Cellular is a feature similar to walkie-talkie that is provided over a cellular phone network. A Push to talk connection is typically connected virtually instantaneously. One significant advantage of PoC is allowing a single person to reach an active talk group at a button press, thus users no longer need to make several calls to coordinate with a group.
Push-to-talk calls are half duplex communications — while one person speaks, the other(s) listen. Traditional mobile phone networks and devices utilize full-duplex communications, allowing customers to call other persons on a mobile or land-line network and be able to simultaneously talk and hear the other party. Such communications require a connection to be started by dialing a phone number and the other party answering the call, and the connection remains active until either party ends the call or the connection is dropped due to signal loss or a network outage. Such a system does not allow for casual transmissions to be sent to other parties on the network without first dialing them up, like is allowed on two-way radios. Full-duplex operation on mobile phone networks is made possible by using separate frequencies for transmission and reception.
Mobile Push-to-Talk service, offered by some mobile carriers, adds functionality for individual half-duplex transmissions to be sent to another party on the system without needing an existing connection to be already established. Since the system is half-duplex (utilizing a single frequency), only one user can transmit by PTT at a time; the other party is unable to transmit until the transmitting user unkeys their PTT button. Currently, PTT service is supported only between parties on the same mobile carrier service, and users with different carriers will be unable to transmit to each other by PTT. However, the advancement of this service will likely bring interconnectivity of PTT traffic between different networks in the near future.
In addition to mobile handsets, the Push-to-Talk service might be complemented with fixed PC applications acting as PTT clients connected to the mobile operator via secured Internet links. Some PC clients are designed for heavy load dispatching, that is, coordinating many issues typically caused when managing large fleets from a dispatch center.
When used with GSM and CDMA networks, the PTT service commonly does not use up the regular airtime minutes that are available for general voice calls.
Nextel Communications introduced mobile push-to-talk in 2003 using iDEN. The "MOTO Talk" feature by Nextel (called Beep-beep or chirp by teenagers) includes both on- and off-iDEN network walkie-talkie service for newer Motorola phone models. The off-iDEN-network headset-to-headset Direct-Talk feature works for a radius of up to six miles.
Sprint plans on implementing Qualcomm's QChat on their EV-DO Revision A network. QChat has connection times of less than a second, which brings it in line with Nextel's MOTO Talk connection speeds. This will in time replace their ReadyLink Push-to-Talk technology.
The Mobile Tornado, Motorola, Nokia, Ericsson, Siemens, Sonim, Wireless ZT, etc. versions of PTT are based on 2.5G or 3G packet-switched networks and use SIP and RTP protocols. These particular versions of PTT are called Push to Talk over Cellular]], which is abbreviated PoC.
The Open Mobile Alliance is defining PoC as part of the IP Multimedia Subsystem, and a first version of OMA PoC standard was finalized in first half of 2005. Full fledged commercial deployments of OMA PoC are few and in between. It is very unclear whether OMA PoC will be seriously launched in the European market.
A pre-standard version of PoC is also defined by the industry consortium made up of Motorola, Nokia, Ericsson, Siemens AG and AT&T Mobility with the aim of creating a commercial offering enabling interoperability between vendors.
Operators using PoC
Several operators are using Pre-Standard Push To Talk Server in GSM / GPRS / EDGE / CDMA / UMTS networks. Most operators, if not all, offer this service as a separate charge that do not use normal voice minutes.
Terminal vendors has several variations of software installed on mobile terminals, so there is no 100% compatibility list available.
In Germany, Talk-IP Ltd. offered Mobile Tornado's PTT solution as managed service for enterprises.
In Japan, NTT DoCoMo implemented Push-to-Talk in late 2005 with the introduction of new FOMA 902i series handsets. It's billed at 5 yen per push, and has an "unlimited" option for 1000 yen/month.
Currently, AT&T Mobility, Alltel, US Cellular and Verizon Wireless offer PTT service using the Kodiak RTX (Real Time Exchange) system to deliver PTT speeds comparable to Nextel and SouthernLinc.
In Canada, the service is provided by several carriers including TELUS Mobility (Mike), Bell Mobility and Aliant Mobility (Bell 10-4). Both Bell and Aliant offer the service which allows customers to use the service in the United States without roaming charges. The service allows a caller to simultaneously communicate with multiple users at different locations. By doing so, this eliminates multiple airtime charges associated with three-way calling. With the cellular number portability coming into effect by March 2007, the PTT (Push-to-Talk) service is expected to increase greatly with the removal of Roamer Access Numbers by August 2006. Roamer Access Numbers had given the freedom for customers to not incur incoming long distance charges by answering calls outside their local calling area if the caller first dials the Roamer Access Number.[citation needed]
In Slovakia, Ardaco developed SecurePTT solution for information and communication security area.
