 The United States no longer insists on using millimeter wave for 5g, but chooses the centimeter wave for China


However, for the construction of 5g, millimeter wave has advantages and disadvantages, such as high speed, good directionality, high frequency and short transmission distance.

But at present, the disadvantage is greater than the advantage, that is, when sub-6 can basically meet the speed and directionality requirements of 5g construction, the cost will increase by 3-5 times if millimeter wave is used. Because of the long transmission distance, the number of base stations will greatly increase. For operators, it is simply unbearable pain. Originally, 5g construction is a high cost. If the cost increases by 3-5 times, operators will Its a big loss.

However, now it seems that the United States has begun to give up, no longer insist on using millimeter wave to build 5g, but also use sub-6 band, because recently the Federal Communications Commission voted to pass a plan, which caused a great stir among American operators.

According to the plan, the U.S. side will buy back the 3.7ghz-4.2ghz spectrum used by satellite companies with us $9.7 billion, and will auction it to telecom companies again, and use this frequency for operators to build 5g, because this frequency is the most suitable for 5g construction.

According to the data, there are 63 operators with 5g network in the world. Of these 63 operators, only 4 are using millimeter wave. Among them, three are from the United States and one is from Uruguay. It can be seen that there are really no other manufacturers to use millimeter wave except the United States. It is estimated that the United States also recognizes the problem and knows that the cost of going it alone is too high. The key is that it may cause 5g to fall behind and lose more than it deserves. Its just that Qualcomm and other manufacturers have been studying millimeter wave technology and supporting millimeter wave in x55 baseband. Now it seems that the millimeter wave has to slow down.
