With the maturity of this great idea, Morse successfully with the current "on" "off" and "long break" instead of the human character is transmitted, which is famous Morse code. In 1843, Morse received $ 30,000 in funding, he used this money to build from Washington to Baltimore became a telegraph line, length of 64.4 kilometers. May 24, 1844 Recycling mobile phone accessories Which is good, in a packed Capitol, the Morse with his hands trembling with excitement, manipulating him more than ten years of effort devoted to the successful development of the telegraph, the 64 kilo Baltimore meters outside the first telegram sent in human history God has created what a miracle! "Better quality phone system: a soft switching technology (connect then disconnect) can overcome the disadvantages of hard switching easily dropped calls, 00 ^ a six systems operating on the same frequency and bandwidth, the system is easier to achieve soft-switching technology, which improve the quality of the phone system uses to determine the vocoder rate adaptive thresholding techniques, powerful error correction, soft-switching technology and rake diversity receiver, which provides small 0? ^ six systems can not match, a high The phone quality ^ flexible frequency planning: the user presses a different serial number to distinguish the different [eight carriers may use high recycling of mobile phone accessories in the adjacent cell, and therefore 001 ^ eight network frequency planning flexibility where recycling of mobile phone accessories, extended simple. ^ multimedia business information, treatment and synthetic methods for multimedia mobile phone system six systems can easily use multiple 00 ^ 1 eight-channel mode and multi-mode 001 ^ eight frames, the transmission rate requirements different than the small 01 ^ 1 way and eight-way flexible, simple and beneficial application of multimedia mobile phone system. The third generation mobile phone system to play 31! 00,30, also known as the European Union's telecommunications giants claimed it as 01 ^ 1 Ding Universal Mobile phone system>. It can be a voice phones and multimedia phones combine its possible value-added services will include images, music, web browsing, video conferencing and other information services .30 means that globally applicable standards, new services, greater coverage and more spectrum resources to support more users. ^ 20 30 system with existing systems is fundamentally different system uses .30 (technology and packet switching technology, rather than technical, and circuit switching systems typically employ 20 technology. In the circuit-switched transmission mode, regardless of whether the two sides to talk call, remain open during the on line and bandwidth compared with the current 20 systems, 30 will support more users and achieve higher transmission rates The information transfer rate of 30 systems in high-speed motion can be achieved ,, walking movement reached 3841, up to 2 indoor sports recycling of mobile phone accessories, electronic Obo (certified), East Gate Recycling mobile phone accessories from Shenzhen Electronic Technology Co., Obo The company offers.
