Chapter 526 Wireless Broadcasting Technology
Professional things like real estate speculation should naturally be left to professionals. Xinβ΄π Arthur is still very assured of the people under his command, and he is even more assured of the capitalists who entered the market after real estate speculation started.
As long as this is started, the real estate industry in the United States will be like a prairie fire that cannot be extinguished in a short time.
Even if most of the real estate fire is extinguished due to the impact of the economic crisis in the future, it will not have any impact on Arthur's income.
Of course, companies that develop real estate in the United States are destined to change their appearance. At least the controllers and capital cannot come from Australasia, and they must officially break away from Australasia.
There is still some good news for Ser.
First of all, the construction of the new capital is proceeding smoothly. After more than a year of construction, many houses and facilities have been built. The new Government Office and the Royal Palace are also under construction. Results are expected within one to two years.
As long as the construction of the Royal Palace and the Government Office are completed, the political center of Australasia can be moved to the new capital. Sydney will completely end its career as the capital, but it will still be the largest city in Australasia.
Among the construction of the new capital, one project was specially approved by Arthur and received strong support from Arthur, and that was the construction of the Australasian National Zoo.
Zoos have a very long history. There are currently many large and small zoos in Australasia, and many of them are large.
But the scale of the newly built National Zoo is absolutely rare, and it has to accommodate animals from all over the world. The cost alone is as high as tens of millions of Australian dollars.
As one of Australasia's future tourism business cards, when building the National Zoo, Arthur specifically ordered that a large number of rare and exotic animals at home and abroad must be collected, and different parks should be divided for these animals from all over the world. .
Of course, these tens of millions of Australian dollars are definitely not in vain. New Arthur's expectation for the National Zoo is to become one of Australasia's future tourism business cards, significantly increase Australasia's tourism visibility, and attract more foreign tourists to Australasia.
At the same time, it can also enrich the entertainment life of Australasians. People will have more entertainment choices besides busy work and ordinary life, which will also improve people's life happiness index.
Under various effects, the cost of 10 million Australian dollars seems not worth mentioning, at least it is worth it.
In addition to the zoo, there are also a large number of botanical gardens, parks, green areas, etc.
St. Arthur's Castle was designed with full consideration of urban internalization and environmental protection. Arthur's purpose is to create the most livable city in the world, and of course it will also be Australasia's future tourism business card.
In addition to the progress in the construction of the new capital, Arthur also received good news, which was the breakthrough progress of some research by the Royal Academy of Sciences.
The first is the research on wireless broadcast technology.
The origin of wireless broadcasting can be traced back to the British scientist J.C. Maxwell in 1873, who proved the existence of radio waves.
In 1888, the German scientist H.R. Hertz generated and received radio waves through spark discharge experiments, which promoted the research of radio waves in various countries around the world.
As early as the beginning of the 20th century, sound broadcasting for broadcasting speech and music was already possible.
However, broadcasting at that time had great limitations. Due to the power of the transmitter, the coverage range of broadcast towers was basically within ten kilometers, and even the coverage range of low-power broadcast towers could only be maintained at 1 to 2 kilometers.
In addition, the anti-interference ability is extremely poor. When the distance is far, the broadcast will be noisy. It is impossible to achieve large-scale commercial use. It is even impossible to achieve nationwide coverage.
But Arthur understood the importance of broadcasting technology. Nationwide wireless transmission would greatly improve the efficiency of communication between regions.
However, there are many problems that need to be solved for broadcasting. The first is that the coverage area of ββthe broadcasting tower must be increased to at least ten kilometers to comprehensively cover the entire city. new
Secondly, the anti-interference ability of broadcasting is also a very important part. In addition to human influence, weather also has a very serious impact on broadcasting. This is also a problem that must be solved if broadcasting is to be commercialized and officially used.
Looking at the research report on wireless broadcasting in his hand, Arthur nodded with satisfaction and asked curiously: "Has the broadcast propagation problem been solved?"
The person reporting on the opposite side was Martin Scorsese, an expert in wireless broadcasting. After hearing Arthur's inquiry, Martin quickly replied: "It has been initially solved, Your Majesty. We have increased the transmitter power of the broadcast tower and used Relay stations to enhance the signal in broadcast transmissions.
According to our tests, as long as there is a signal transfer station in the middle, the fading signal frequency can be amplified again, even reaching the frequency when it was just launched.
According to our estimates, if the weather is good and relay stations are laid all the way, the frequency sent from Sydney can be received in Perth in 10 to 20 minutes, thus achieving nationwide coverage of the broadcast. "
new
Perth is the capital of Western Australia, separated by the entire country from Sydney, which is located in the eastern part of Australia.
If the signal transmission between Perth and Sydney can be achieved, this means that the entire Australia is covered.
As for the further overseas territories and New Zealand, these are areas that current wireless broadcast technology cannot cover, and Arthur fully understands.
To be honest, Arthur is quite satisfied to be able to achieve wireless broadcast coverage in Australia.
After all, technology develops slowly, and no one can become a big fat man in one bite. It takes a certain amount of time to develop to promote technological progress.
"What about the anti-interference problem of the signal? How is the current anti-interference ability?" Arthur continued to ask.
Only when the two problems of coverage and anti-interference are solved can wireless broadcast technology be officially put into use.
Therefore, anti-interference ability is also a very important part and is an unavoidable problem in broadcast use.
βWe have strengthened the broadcast signal, and the anti-interference capability has improved compared to previous broadcasts.
However, the impact of special weather still cannot be solved. The magnetic field will also affect the broadcast transmission signal, which cannot be solved in a short time. β Martin explained.
Current technology obviously cannot completely ensure that radio broadcast signals will not be interfered with. After all, in addition to extreme weather, magnetic fields are also the culprit that affects broadcast signals.
"But under normal weather conditions, the current wireless broadcast signal can still be guaranteed. In areas relatively close to transfer stations and signal base stations, the signal will basically not be affected." Martin continued.
Arthur is completely able to accept what Martin said. After all, it is only the early 20th century, and there is no comparison with technology 100 years later.
Now that radio technology can be used, it has progressed compared to history, and Arthur will naturally not put forward more stringent requirements.
As long as it can be used in normal weather, Arthur's needs for wireless broadcast technology will be met for ten years.
Anyway, there is still a lot of time to improve. Arthur is confident that he will catch up with the level of later generations in advance. Even if it takes decades of hard work, Australasia can definitely afford to wait.
"What is the construction cost of broadcasting stations and relay stations? If it is to be fully laid out in Australia, can the government bear the burden?" Arthur continued to ask the question he wanted to ask.
The popularization of broadcasting also needs to consider another issue, and that is the cost of building broadcast base stations.
If the cost is too high, dissemination across the country will be a hassle and will hinder the use of broadcasting.
"The current construction cost of a broadcast base station is about 4,000 Australian dollars, and the construction cost of a transfer station is about 4,000 Australian dollars. Of course, this also depends on the geographical environment of the corresponding region, as well as the material and labor costs required to build the base station." Martin replied.
"What about the coverage of broadcast base stations and relay stations?" Arthur asked.
"In vast plain areas, the coverage range of broadcast base stations can be expanded to about 20 kilometers, and can even be transmitted as far as 25 kilometers. But if it is in mountainous areas, the transmission range will be affected to a certain extent, and the specific value is not stable. But the initial estimate is that it can be guaranteed to be about 10 kilometers." Martin continued to hand over a piece of information and replied very respectfully:
"The coverage area of ββthe transfer station in plain areas can be stable at more than 15 kilometers. Mountainous areas will also be affected, and it can be stabilized at about 10 kilometers."
Arthur nodded.
Arthur is currently satisfied with the signal coverage of base stations and relay stations.
The diameter of a small city is only a few kilometers to more than ten kilometers. Generally speaking, 1 to 2 base stations can fully cover it.
Large cities will need to build more base stations and transfer stations, but there are not many large cities in Australasia. The two largest ones are Sydney and Melbourne.
In addition, there are a lot of uninhabited areas and deserts in Western Australia. Naturally, there is no need to build base stations and transfer stations in these areas. You can't let the animals in the desert listen to the radio!
In this way, a considerable amount of cost can be saved. At least within Australia, at least half of the land does not require the construction of base stations and transfer stations, and the actual costs required are completely within the scope of the government's affordability.
At present, the areas that broadcasting needs most coverage are actually some cities in the southeast, south and north of Australia.
The deserts and deserts in the central and western areas are basically uninhabited, and there is no need to build base stations for the time being.
The large-scale construction of radio stations is conducive to controlling domestic public opinion, which is very effective for Arthur to strengthen domestic public opinion control.
No matter what, public opinion control is Arthur's bottom line and an important line of defense for ensuring national security and stability.
