Embodiment 1

[0204] Embodiment 1: The uplink and downlink frequency bands of WCDMA occupy 1920-1980 MHz and 2110-2170 MHz frequency bands respectively. The present invention divides the frequency band of 1920~1980MHz into two parts of 1920~1945MHz and 1955~1980MHz (or two parts of 1920~1940MHz and 1960~1980MHz). Ask the mobile phone to select the lower half of the frequency as the transmission frequency. On the contrary, the calling mobile phone selects the lower half frequency, and the called mobile phone selects the upper half frequency.

Embodiment 2

[0205]Embodiment 2: When using code division multiple access communication technology (CDMA), both the calling mobile phone and the called mobile phone use 825~835MHz as their transmission frequency bands (CDMA uplink RX: 825~835MHz, downlink TX: 870~880MHz) . If there is an interference problem because the mobile phone's own transmitting frequency is the same as the receiving frequency, it should be agreed with the communication partner to avoid it by using the time-sharing method of transmitting and receiving.

Embodiment 3

[0206] Embodiment 3: adopt the radio communication frequency of existing mobile phone, the radio transmission power of mobile phone, give mobile phone new ability to directly send and receive radio signal each other simultaneously, realize the communication functions such as non-relay direct conversation between mobile phone, text file Transfer function, picture file transfer function, music file transfer function, game function and so on. In the current mobile phone communication, the frequency used by the signal sent by the mobile phone to the base station is different from the frequency of the signal sent by the base station to the mobile phone, which is divided into two frequency bands, uplink and downlink. In fact, mobile phones have the ability to receive and transmit signals in both frequency bands. Just a little tweaking in design and setup. Coupled with the new software, there is no technical problem for phones to talk directly to each other. The communication funct...

Abstract

The invention relates to a method of free no-repeater mobile communication. A method that a radio signal is directly transmitted and received between mobile phones is adopted, and the mobile communication between a mobile phone and a mobile phone, a mobile phone and a computer and two or more parties of users between computers is realized without handshaking and relay service from telecom operators. The communication method can be call ethernet communication for short; the ethernet communication well solves the problem of information asymmetry, is like the seventh sense organ of a person, and enables the person to remotely sense the identity information and other any information willingly disclosed by other persons or the unit at the distance of a plurality of meters, hundreds of meters and even a plurality of kilometers; both the individual and the unit can issue the own information to the space ranged from a plurality of kilometers to a dozen kilometers around to provide for searching and sensing for other persons; and each user has one open code or code name, and even if you are strangers, you can also send a short message or call him or her in the remote place for greeting.

Description

technical field [0001] The invention belongs to the radio application field, and the device implementing the invention is a part of mobile communication technology and products, and belongs to electronic products. Background technique [0002] The most widely used radio communication tool is a mobile phone (hereinafter referred to as a mobile phone). Regardless of domestic or overseas, any mobile phone, whether it uses GSM or CDMA, or the latest 3G technologies such as WCDMA, CDMA-2000, and TD-SCDMA, all use base stations to forward wireless signals. The mobile phone carries out the standardized modulation of the signal according to a fixed standard, and they have a unified standard without exception, otherwise it will be impossible to use it normally, and it will not be able to obtain a network access license. [0003] GSM, CDMA and 3G technologies: [0004] GSM is a communication technology that combines FDMA (frequency division) and TDMA (time division) systems, and all...
