Speculation in real estate is a professional thing that naturally has to be done by professional people. Arthur is still very relieved of the people under him, and even more at ease with the capitalists who entered the market after the real estate speculation was opened.

As long as this is opened, the real estate in the United States will be like a prairie fire, and it will be impossible to extinguish it in a short time.

Even if the real estate fire is extinguished in the future due to the impact of the economic crisis, it will not have any impact on Arthur's earnings.

Of course, the company that develops real estate in the United States is destined to have a makeover, at least the controller and the capital cannot come from Australasia, and on the bright side, they must dissociate themselves from Australasia.

In February 1920, there was some good news for Arthur.

First of all, the construction of the new capital is proceeding smoothly, after more than a year of construction, a lot of houses and facilities have been built, and the new government council and royal palace are also under construction, and it is expected that in one to two years there will be results.

As long as the construction of the palace and the government council is completed, the political center of Australasia can be relocated to the new capital, and Sydney will completely end its career as the capital, but it will still be the largest city in Australasia at present.

One of the constructions of the new capital was approved by Arthur and strongly supported by Arthur, and that was the construction of the Australasian National Zoo.

The history of zoos is very long, and Australasia currently has large and small zoos, and there are many large ones.

But the new National Zoo is definitely rare in scale, and it costs tens of millions of dollars alone to accommodate animal systems from all over the world.

As one of Australasia's future tourism cards, when building a national zoo, Arthur specially instructed that a large number of exotic animals at home and abroad must be collected, and different parks must be divided for these animals from all over the world.

Of course, the tens of millions of Australian dollars are definitely not spent in vain. Arthur's vision for the National Zoo is to become one of Australasia's future tourism cards, greatly increase the tourism profile of Australasia, and attract more foreign tourists to Australasia.

At the same time, it can also enrich the entertainment life of Australasian people, and people have more entertainment choices in addition to their busy work and ordinary life, which will also improve people's life happiness index.

With all these effects, the $10 million cost is not worth mentioning, at least it is worth it.

In addition to the zoo, there are also a number of botanical gardens, parks, and greenery.

Fort St. Arthur was designed with the city in mind, with the aim of creating the world's most liveable city, and of course Australasia's future tourist card.

In addition to the progress in the construction of the new capital, Arthur also had good news, namely some breakthroughs in the research of the Royal Academy of Sciences.

The first is the research of wireless broadcasting technology.

The origin of radio broadcasting can be traced back to 1873 when the British scientist J. J. Brown was born in 1873. C. Maxwell, it was he 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 study of radio waves in countries around the world.

As early as the beginning of the 20th century, sound broadcasting with voice and music was already possible.

However, the broadcast at that time had a large limitation, because of the transmitter power, the coverage of the broadcast tower was basically within 10 kilometers, and even the coverage of the low power broadcast tower could only be maintained at 1 to 2 kilometers.

In addition, the ability to resist interference is extremely poor, and the broadcast is a noise at a distance, and it is impossible to achieve large-scale commercial use, and it is impossible to cover the whole country.

But Arthur understands the importance of broadcasting as a technology, and wireless transmission throughout the country will greatly improve the efficiency of communication between regions.

However, there are many problems that need to be solved by broadcasting, first of all, the coverage of the broadcasting tower, which must be increased to at least 10 kilometers in order to cover the entire city more comprehensively.

Secondly, the anti-interference ability of broadcasting is also a very important part. In addition to human influences, the impact of weather on broadcasting is also very serious, and it 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 very curiously: "Has the problem of broadcasting been solved?" ”

The person who reported to him on the other side was Martin Scorsese, an expert in the study of radio broadcasting, and after hearing Arthur's inquiry, Martin hurriedly replied: "It has been preliminarily resolved, Your Majesty." We have increased the transmitter power of the broadcast towers and used relay stations to enhance the signal in the broadcast transmission.

According to our tests, as long as there is a relay station in the middle of the signal, the frequency of the decayed signal can be amplified again, even to the frequency when it was just transmitted.

According to our estimates, in good weather, if a relay station is laid along the way, the frequency from Sydney can be received in Perth after 10 to 20 minutes, so as to achieve nationwide coverage. ”

Perth is the capital of Western Australia, separated from Sydney, which is located in the eastern part of Australia.

If the signal can be transmitted between Perth and Sydney, it means that the whole of Australia is covered.

As for the further overseas territories and New Zealand, this is an area that cannot be covered by current radio broadcasting technology, and Arthur understands it perfectly.

To be honest, Arthur is quite satisfied with being able to achieve over-the-air coverage in Australia.

After all, technology is developing slowly, and no one can eat a big fat man in one bite, and it takes a certain amount of time to develop to promote the progress of technology.

"What about the anti-interference problem of the signal? What is the current anti-interference ability? Arthur continued.

The two problems of coverage and anti-interference are solved, and the technology of wireless broadcasting can be officially put into use.

Therefore, the ability to resist interference is also a very important part, which is an unavoidable problem in the use of broadcasting.

"We have strengthened the signal of the broadcast, and the anti-interference ability has improved compared to the previous broadcast.

However, it is still impossible to solve the impact of special weather, and the magnetic field will also affect the transmission signal of broadcasting, which cannot be solved in a short time. Martin explained.

It is clear that the current technology is not yet able to completely ensure that the radio broadcast signal will not be interfered with, after all, in addition to extreme weather, magnetic fields are also the main culprit affecting the broadcast signal.

"But under normal weather conditions, the current wireless broadcast signal can still be guaranteed. In areas close to the relay station and signal base station, the signal is basically not affected. Martin continued.

Arthur was perfectly comfortable with what Martin was saying, after all, it was only the early 20th century, and it was not at all comparable to the technology 100 years from now.

Now that radio technology can be used, Arthur will not make more stringent requirements.

As long as it can be used in normal weather, it has met Arthur's demand for wireless broadcasting technology within ten years.

Anyway, there is still a lot of time to improve, and Arthur is confident that he will catch up with the level of future generations in advance, even if it takes decades of hard work to do so, but Australasia can afford to wait.

"How much does it cost to build a broadcasting station and a transfer station? If it were to be fully rolled out in Australia, would the government be able to bear the burden? Arthur continued to ask the questions he wanted to ask.

There is also an issue to consider when broadcasting becomes widespread, and that is the cost of building a broadcast base station.

If the cost is too high, it will be a problem to spread throughout the country, and it will also hinder the use of broadcasting.

"The current construction cost of the broadcast base station is about $6,000 and the construction cost of the transfer station is about $4,000. Of course, this also depends on the geographical environment of the corresponding region, as well as the cost of materials and labor 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 of the broadcast base station can be extended to about 20 kilometers, and even as far as 25 kilometers. However, if it is in a mountainous area, the transmission range will be affected to a certain extent, and the specific value is not stable, but the preliminary estimate can guarantee that it is about 10 kilometers. Martin continued to hand over a document and replied very respectfully:

"The coverage area of the transfer station can be stabilized at more than 15 kilometers in the plain area, and the mountainous area will also be affected, and it can probably be stabilized at about 10 kilometers."

Arthur nodded.

At present, Arthur is still satisfied with the signal coverage of the base station and the transfer station.

The diameter of a small city is about a few kilometers to more than ten kilometers, and generally speaking, 1 to 2 base stations can be fully covered.

The number of base stations and transfer stations that need to be built in large cities will be more, but there are not many large cities in Australasia, and the largest ones are Sydney and Melbourne.

In addition, there are a large number of uninhabited areas and deserts in the western part of Australia, and these areas naturally do not need to build base stations and transfer stations, so you can't listen to the radio for the animals in the desert!

In this way, there are considerable cost savings. At least in Australia, at least half of the land does not need to build base stations and transit stations, and the actual cost is completely within the limits of what the government can afford.

At present, the most important area of radio coverage is actually some cities in the southeast, south and north of Australia.

The deserts and deserts in the central and western parts of the country 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 public opinion in the country, and it is still very effective for Arthur to strengthen the control of public opinion in the country.

In any case, the control of public opinion is Arthur's bottom line, and it is also an important line of defense to ensure national security and stability.
