Eliminated by the market in the hottest 4G era CDM

Eliminated by the market in the 4G era is CDMA the next PHS

except for an announcement on Chinatelecom station, most Chinatelecom users only find that they need to change to GSM when they are in Thailand, Brazil and New Zealand. It shouldn't be surprising to ask for caller information. CDMA operators in the above three countries are exploring the qdlp model of venture capital market after a transition period of one year or four years. In early July this year, they closed the CDMA network and switched to GSM. In addition, a number of CDMA operators, including Japan, South Korea, Canada and the United States, announced several years ago that they would abandon the route of upgrading from CDMA to 3G or 4G

this is largely related to Qualcomm, the main advocate and holder of CDMA technology. Like many well-known American high-tech companies, Qualcomm was initially founded in the laboratory. The founders Jacob and Viterbi always believe that three aspects of the machining process of the electronic tensile testing machine: first, it will eventually become an indispensable tool for everyone; Second, there can be more than one standard, which is selected by the market; Third, technology will eventually lead the market

cdma is the product of this idea. It occupies less frequency band resources, but provides a better experience and can accommodate more users. Just as gates let everyone have computers, the above beliefs have enabled Qualcomm to invest heavily in R & D and become the mobile overlord 20 years later

however, Qualcomm has not become Microsoft. Although it is recognized that the technology is leading, the beneficiaries of CDMA, strong operators in the mobile field and cautious manufacturers do not feel grateful for this. Because Qualcomm has always refused to make concessions on patent licensing fees, Qualcomm has provoked numerous lawsuits around the world for itself, which eventually led to the betrayal of UMB

umb is the technical standard for upgrading CDMA to 4G, which is different from the LTE standard for upgrading GSM to 4G. This standard can make the smooth transition from CDMA to 4G. To put it simply, the former is to replace almost all the expensive equipment before upgrading once, while the latter can be repaired on the system without waste or less waste, just as we can complete the upgrade by adding a memory to the computer and changing a motherboard or CPU

this is obviously a good idea, which is especially meaningful in the 3G era when operators often gamble billions of dollars. But CDMA operators and manufacturers do not think so. What they see is that the number of CDMA terminals that can be selected is far less than that of GSM, while 3G and 4G upgrading competitions are life and death, and good wine is afraid of the depth of the alley. They prefer the latter between the non acclaimed technology leading the market and the success of the booming industrial chain

as a result, when UMB was put into commercial trial, there were no supporters. Qualcomm had to give up UMB, which originally meant ultra wideband in English, and announced that it would accept LTE, which originally meant long-term evolution in English. This was four years ago

this is common in the life and death competition in the communication industry. You can see Motorola, which has failed on the iridium star, or apple, which is complacent but still has numerous fans. In this strange industry, the importance of the industrial chain even exceeds whether the technology itself is advanced or not

this does not mean the failure of CDMA operators such as Chinatelecom. When giving up UMB, Bill Davidson, senior vice president of global marketing and investor relations of Qualcomm, said that there is no easier way for WCDMA operators to upgrade to LTE than CDMA operators

there seems to be no loser in this war. Since 2010, Verizon, an American CDMA operator, has turned to LTE after giving up UMB, and has become the largest operator in the United States. Its 4G network covers two-thirds of the United States. The new 4G even beats the iPhone in sales. The suspension of UMB research and development has little impact on Qualcomm's performance, because Qualcomm's previous accumulation in GSM technology allows Qualcomm to continue to lead the market in the LTE era

the only regret is that CDMA, an excellent technology, will disappear on the historical stage of the communication industry by integrating into LTE. From the perspective of Cheng Wang defeating thieves, it is not impossible to say that CDMA is another PHS. The biggest similarity between PHS and CDMA is that they are eliminated in the natural selection of the market, but the biggest difference is that the former is replaced by better technology, while the latter is abandoned by the mediocre market

however, 4G may not be the end. The market may make mistakes, but its charm is that it can correct itself. Remember what heitirama, the mother of CDMA, a female scientist and film star, said before her death: movies are often limited to a certain region and era, and technology is eternal
