跳频技术的原理
跳频技术的原理Frequency hopping is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels. The underlying principle of frequency hopping is to minimize interference from other radio signals and to ensure secure communication.跳频是一种通过快速在许多频道之间切换载波来传输无线电信号的方法。
跳频的基本原理是最大程度地减少来自其他无线电信号的干扰，并确保通信的安全性。
The concept of frequency hopping was first introduced by the Hollywood actress Hedy Lamarr and composer George Antheil, who patented the technology during World War II as a means of preventing the jamming of radio-controlled torpedoes. This early application of frequency hopping laid the foundation for modern-day wireless communication systems.频率跳变的概念最早由好莱坞女演员海蒂·拉玛和作曲家乔治·安泰尔首次引入，他们在二战期间申请了技术专利，作为一种防止无线电遥控鱼雷被干扰的手段。
这种早期对频率跳变的应用奠定了现代无线通信系统的基础。
The fundamental principle behind frequency hopping is to divide the available frequency spectrum into multiple frequency bands and then rapidly switch the carrier signal among these bands. This dynamic switching of frequencies makes it challenging for unauthorized users to intercept the signal or for other signals to interfere with the transmission.跳频背后的基本原理是将可用的频谱分成多个频带，然后快速在这些频带之间切换载波信号。
防撞系统英文
The introduce of the automobile anti-collision control systemThe accident of automobile rear-end collision has taken place frequently in recent years,and rear-end collision warning system has good use in improving expressway traffic safety,so the warning system has been paid more attention in the world. The vehicle collision avoidance alarm apparatus system was introdued according to the ultrasonic measurement distance’s system . Th e system can automaticanlly xeamine the distance between the back and the nearest obstacle ( or the distance among cars ) whicwould be demonstarted through LED that when it arrives the limit distance ,the system can send out the warning and reminds the driver for preventing the vehicle colliding . The experimental results showed that,the system illustrates a good prospect of application and xetension highways, streets, parking, garage and other crowded places narrow reverse, the driver should not only forward but also looking back, a little rear-end careless accidents can occur. According to related statistics, 15% of motor vehicle collisions when the vehicle is reversing, as the capacity of the latter caused by bad.So after the increase of motor vehicles as the ability to detect obstacles on the development of the rear of the car reversing radar has become the research hotspot in recent years. Security to avoid obstacles on the premise that the rapid and accurate measurement of obstructions and the distance between motor vehicles. To this end, the design of a single-chip microcomputer as the core, the use of ultrasonic ranging to achieve non-contact reversing radar system. Generally refers to ultrasonic frequencies above 20 kHz mechanical waves, with penetrating, and attenuation of small, reflecting the ability and so on. Work, the ultrasonic transmitter continuously emits a series of consecutive pulses to the measurement of logic circuits to provide a short pulse. Finally, signal processing devices based on the received signal for processing the time difference, automatic calculation of turnout and the distance between obstacles. Ultrasonic Ranging simple, low cost, easy production, but the transmission speed by a larger weather can not be precise range; In addition, the ultrasonic energy and the attenuation is directly proportional to the square of the distance, the farther the distance, the lower sensitivity and thus Ultrasonic Ranging way so that only apply to a shorter distance. At present, ultrasonic range finder at home and abroad in general, the ideal distance of the measurement 4 ~ 5 m, thusreversing radar are used in cars, such as close range in this paper, according to the spread of sound waves in air reflection to ultrasonic transducer interface components, based on MCU AT89C51 ultrasonic range-finder.

The receivers are preferably Super Heterodyne typeor Near Zero IF type. The antennas are preferably spaced apart at a distance from each other. More preferably, the antennas are 25cm or more spaced apart from each other.The two spaced apart antennas are preferably operatively connected to enable the processor to process the signal inputs to determine the location of the transmitter. The receiving antennas are preferably arranged with one antenna peak tuned and the other is dip tuned so that they are 90 degrees out of phase. The processor preferably can combine the two signals for a summed RSSI reading and measure a phase shift to determine the position of the transmitter means.Preferably the antennas have resonator coils that enable them to be dynamically tuned. With tuning the antenna, the predefined frequency is preferably set by varying the capacitance of the coil by the voltage to peak tune the antenna to the definedfrequency.The transmitter means is preferably a transponder that transmits a signal but not receive a signal. The transmitter means is preferably portable. Alternately transmitter means may be a transponder which is activated on receiving a radio frequency signal from the vehicle and transmits a location signal back to the vehicle. Preferably the transponder is wearable and has a frequency between 200Khz to 8 Ghertz. More preferably the transponder has a frequency between 300 Khz and 500 Khz.The transponder preferably has a plurality of capacitors so that the transponder antenna can be dynamically tuned and shifted in 5 KHz increments to form 5 KHz channels. The signal is carrier modulated by frequency shift keying (FSK) where the keying rate is 300 Htz and the frequency shift is +/- 1 Khz either side of the carrier forming a 300Htz tone.The radio frequency signal is preferably a suitable frequency to enable identification of the vehicle and activation of the vehicle to move in accordance with the processor programming. The radio frequency signals are preferably arranged in channels. The signal processing is preferably able to identify separate transmitter channels and negate any adjacent channel interference.Within the defined range of the radio frequency signals, the number of vehicles responding to transponder specific signals within an area may be increased by one or more methods including random transmission cycle for the transponders where the transmissions are coded so that they can be decoded and used by the corresponding vehicle. Alternately the frequency from the transponder may be modulated at a FSK keying rate of 500Htz with +/- 1 Khz frequency shift so that the receivers can identify their corresponding transponder. Furthermore the transponder preferably has a random number generator which is used to trigger transmit time so that transmissions are not synchronized to avoid the situation where multiple simultaneous transmissions are received by a receiver.。

世界各国LTE频段分布
List of LTE networksFrom Wikipedia, the free encyclopediaThis is a list of commercial Long-Term Evolution (LTE) networks around the world, grouped by their frequency bands. Some operators utilizing multiple bands, therefore repeated in respective sections.General informationFor technical details on LTE and a list of its designated operating frequencies, bands, and their common names, see LTE Frequency bands. Bands 33 to 44 are TD-LTE-Networks.Networks on the global LTE-bands 1, 3, 7, 28 (FDD-LTE) or 38, 40 (TDD-LTE) are suitable for future global roaming in ITU Regions 1, 2 and 3.Networks on LTE-band 8 (FDD-LTE) may allow global roaming in the future (ITU Regions 1, 2 and 3) (Long-term perspective).Networks on LTE-band 20 (FDD-LTE) are suitable for roaming in ITU Region 1 (EMEA) only.Networks on LTE-bands 2 and 4 (FDD-LTE) are suitable for roaming in ITU Region 2 (Americas) only.AfricaContents1 General information2 Africa3 Americas4 Asia5 Europe6 Middle East7 Oceania8 See also9 ReferencesOperator Country Frequency (MHz)BandDuplexmode Launch date NotesMovicel Angola 18003FDD April 2012[1]Unitel Angola 21001FDD December 2012[2][3]Etisalat Egypt Egypt 21001FDD 2013 (in Trial)[3]Blueline Madagascar 230040TDD 2013 (in Trial)[3]Emtel Mauritius 18003FDD May 2012[4][5]Orange Mauritius Mauritius 18003FDD June 2012[5][6]MTC Namibia Namibia 18003FDD May 2012[7][8]TN Mobile Namibia 18003FDD November 2013[3][9]Glo MobileNigeria21001FDD2013 (planned)[3][10]Americas Caribbean(Globacom)Smile Nigeria Nigeria80020FDD March 2013[3][11]Spectranet NigeriaNigeria230040TDD August 2013[3][12][13]SWIFTNigeria230040TDD2013 (planned)[3]SWIFT Nigeria350042TDD2013 (planned)[3]UL/DL Frequencies?Somcable /Glocell / Sahal Telecom Somalia700(?)(?)TBD (planned)[14][15]FWB[D 1][citation needed]Cell CSouthAfrica21001FDDOctober 2013 (inTrial)[3][16][17]iBurst Ltd.SouthAfrica18003FDD2013 (planned)[3]iBurst Ltd.SouthAfrica26007FDD2013 (planned)[3]MTN South AfricaSouthAfrica18003FDD December 2012[18][19][20]NeotelSouthAfrica80020FDD2013 (in Trial)[20]FWB[D 1]NeotelSouthAfrica18003FDD August 2013[21][22]FWB[D 1]Telkom / 8taSouthAfrica230040TDD April 2013[3][12][23][24]VodacomSouthAfrica18003FDD October 2012[19][25]Smile Tanzania Tanzania80020FDD August 2012[11][26]MTN Uganda Uganda260038TDD April 2013[12][27][28][29] Orange Uganda Uganda80020FDD July 2013[29][30] Smile Uganda Uganda80020FDD June 2013[11][29][31][32] TMP Uganda Uganda230040TDD2013 (planned)[3]EconetZimbabweZimbabwe18003FDD August 2013[3][33]Operator Country Frequency(MHz)BandDuplexmodeLaunch date NotesDigicelAntigua andBarbuda700 b c17FDD November 2012[34][35]SETAR Aruba18003FDD November 2013[36]Central America and South AmericaBTC / C&W LIME Bahamas 700 b c 17FDD 2014 (planned)[3][37][38] UL/DLFrequencies?C&W LIME CaymanIslands 700 b c 17FDD December 2013[39][40]Digicel Cayman CaymanIslands 700 c 13FDD December 2013[41][42]Tricom Dominican Republic 19002FDD March 2013[3][43] UL/DLFrequencies?Orange DominicanaDominican Republic18003FDDJuly 2012[3][44]Operator CountryFrequency (MHz)BandDuplexmodeLaunch date NotesPersonal Argentina Argentina 26007FDD 2013 (in Trial)[45][46]Movistar Argentina Argentina 17004FDD 2013 (in Trial)[46][47]BTL Belize 8505FDD 2014 (planned)[3] UL/DL Frequencies?BTL Belize 19002FDD 2014 (planned)[3] UL/DL Frequencies?Entel Bolivia Bolivia 700 c 13FDD December 2012[48][49]Tigo Bolivia Bolivia (?)(?)FDD 2013 (planned)[50]Claro Brasil Brazil 26007FDD December 2012[51][52]Oi Brazil 26007FDD April 2013[52][53]On Telecom Brazil 260038TDD March 2013[12][52][54][55]Provider formerly named Sunrise.SKY Brasil Brazil 260038TDD December 2011[12][52][56] FWB [D 1]TIM Brasil Brazil 26007FDD July 2013[52][57]Vivo Brazil 26007FDD April 2013[52][58]Claro Chile Chile 26007FDD June 2013[59][60]Entel Chile Chile 26007FDD March 2014(planned)[60][61]Entel Chile Chile 350042TDD 2012 (in Trial)[62] UL/DL Frequencies?Movistar Chile Chile26007FDD November 2013[60][63]Avantel Colombia Colombia 17004FDD TBD (planned)[64][65]ClaroColombia 26007FDDTBD (planned)[64][65]North America (USA, US Territories & Canada)Apart from their main spectrum holdings across large regions in the country (listed below) the major US carriers (AT&T, Sprint, T-Mobile & Verizon) also hold various Cellular Market Area (CMA) and/or Economic Area (EA) licenses for the AWS 1700 band, as well as Major Trading Area (MTA) and/or Basic Trading Area (BTA) licenses for the PCS 1900 band.

Beside the mobile phone specifications, GSMArena is happy to also provide you with its own country-based frequency band directory. It's not operator-specific and it's helpful if you are choosing a handset to use in your home country or if you are making sure your phone will work in the country you red to on mobile phones and multimedia smartphones has nothing to do with 2nd, 3rd generation, or 4th generation protocols but the frequency on which the phone operates. Dual means two, tri means three, and quad means four, and these prefixes indicate the frequency transmission available to the specific phone and the arrangement with the service provider and carrier. A 3G phone or a 4G phone uses W-CDMA 2100 (Wideband Code Division Multiple Access) to provide video telephony and increased data speeds. Although it might appear that a 3G or 4G phone can do so much more, it does not upgrade the band frequency. A dual band phone remains a dual band phone and a tri band stays a tri band.
lte ca载波间隔
lte ca载波间隔English:The LTE Carrier Aggregation (CA) allows for the combination of multiple LTE carriers to increase bandwidth and enhance network performance. One key aspect of CA is the carrier spacing, which refers to the frequency separation between individual LTE carriers. The carrier spacing for LTE CA is typically set to MHz, MHz, MHz, MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, or 20 MHz. These different carrier spacing options provide flexibility in configuring LTE CA based on the available spectrum resources and network requirements. The choice of carrier spacing depends on several factors, including the frequency bands and channel bandwidths used in the network, as well as the desired amount of carrier aggregation and overall network capacity. It is also important to consider the impact of carrier spacing on radio resource management, interference management, and device compatibility. In terms of device compatibility, the UE (User Equipment) needs to support the specific carrier spacing used in the network to properly receive and decode the LTE signals. Carrier spacing is a critical parameter in LTE CA deployment, as it affects the efficiency and performance of theaggregated carriers. By optimizing the carrier spacing, network operators can maximize the benefits of LTE CA, such as higher data rates, improved spectral efficiency, and better overall user experience.中文翻译：LTE载波聚合（CA）允许将多个LTE载波组合在一起，以增加带宽和提升网络性能。
常识业余无线电常用术语
业余无线电常用术语（版本:2011-0703）业余无线电的活动和管理离不开接触一些常用的术语，正确了解这些“行话”的含义是业余无线电爱好者和管理者的基本功。
为了便于初学者学习，下面列出一些术语的正式定义及其来源供参考。
我们以后将可能不断补充有关内容，请注意本文件的修改日期。
什么是各国无线电“主管部门（administration）”？ITU《无线电规则》第 1.2条：主管部门：负责履行《国际电信联盟组织法》、《国际电信联盟公约》和行政规则内所规定的义务的任何政府部门或机关（《组织法》第1002款）。
什么是“电信（telecommunication'？ITU《无线电规则》第 1.3条：电信：利用导线、无线电、光学或其他电磁系统进行的对符号、信号、文字、图像、声音或任何性质信息的传输、发射或接收（《组织法》）。
什么是“无线电（radio）”？ITU《无线电规则》第 1.42条：无线电：对无线电波的使用的通称。
什么是“无线电波（radio waves）”？ITU《无线电规则》第 1.5条：无线电波或赫兹波：不用人工波导而在空间传播的、频率规定在3000GHz以下的电磁波。
讨论：几十年以前由于探测能力限制的影响，无线电技术界常常把频率在数十千赫以上的电磁波才称为无线电波，现在在某些专门领域中也可能沿用一些比较狭义的关于无线电频率的定义。
但是随着器件的改进和数字处理技术的进步，可利用于通信的电磁波频率越来越低，例如军事、矿业和业余无线电通信所用的频率已经向低端延伸到数千赫甚至更低。
按照ITU的这一定义，无线电波的频率没有设置下限。
根据麦克斯韦理论，只要不是零频率的交变电场或者磁场，空间就会有电磁波存在，也就有无线电波。
什么是“无线电通信（radiocommunication'？ITU《无线电规则》第 1.6条：无线电通信：利用无线电波的电信（《组织法》）（《公约》）。
无线电频谱细分为那些频段（Frequency bands）和波段（wavelength bands）？ITU《无线电规则》靠•/条:无线电频谱应细分为九个频段，按照下表以递增的整数列示。
LTE的载波聚合技术CA
LTE的载波聚合技术人们对数据速度的要求愈来愈高，载波聚合（Carrier Aggregation ，CA) 成为运营商面向以后的必然选择。
什么是载波聚合？简单一点说，确实是把零碎的LTE频段归并成一个“虚拟”的更宽的频段，以提高数据速度。
咱们先来看看全世界CA进展历程。
1）2021年，韩国SK电信第一次商用CA，其将800MHZ频段和频段聚合为一个20MHZ频段，以取得下行峰值速度150Mbps。
LGU+一个月后跟进。
2）2021年11月，英国运营商EE宣布完成inter-band 40 MHz载波聚合，理论速度可达300Mpbs。
3）2021年12月，澳大利亚运营商Optus第一次完成在TD-LTE上载波聚合。
紧随其后，日本软银、香港CSL、澳大利亚Telstra等也接踵部署或商用载波聚合。
刚开始，载波聚合部署仅限于2载波。
2021年，韩国SK电信、LGU+成功演示了3载波聚合。
随着技术的不断演进，相信以后还有更多CC的载波聚合。
固然还包括TDD和FDD、LTE和WiFi 之间的载波聚合。
中国电信在2021年9月成功演示了FDD和TDD的载波聚合，这也是载波聚合路上一个新的里程碑。
为了说清楚载波聚合，咱们第一来了解一下LTE的频段分派。
载波聚合的分类载波聚合要紧分为intra-band 和inter-band载波聚合，其中intra-band载波聚合又分为持续(contiguous)和非持续(non-contiguous)。
关于intra-band CA (contiguous)中心频点距离要知足300kHz的整数倍，即Nx300 kHz。
关于intra-band 非持续载波聚合，该距离为一个或多个GAP（s）。
3GPP关于载波聚合的概念以下图是3GPP关于载波聚合从Re-10到Re-12的概念历程。
3GPP Rel-10概念了bands 1 (FDD) 和band 40 (TDD)的intra-band 持续载波，别离命名为CA_1C 和CA_40C。
