These companies hope to use these bands to provide global broadband services from space < p > the deadline for the latest round of FCC's proposal to use V-band is midnight on Thursday, which prompted many companies to urgently submit applications. Chris quilty, founder of quilty analytics, a research and investment company focusing on satellite communications, said: "it's like enclosure." < / P > < p > quilty explained: "The most difficult aspect of building a low earth orbit broadband system is to obtain spectrum, rather than manufacturing and launching satellites. Every company with future plans in this field tries to occupy these current ownerless places. "< / P > < p > it is worth noting that the companies that submitted their applications on Thursday have different backgrounds and existing plans. < / P > < p > Amazon is trying to build an initial space Internet composed of 3236 satellites, called" project Kuiper " Astra, a rocket manufacturer, has previously announced plans to start building satellites. Boeing obtained FCC approval earlier this week to use 147 satellites to build the space Internet. < / P > < p > oneweb, owned by the UK, initially planned to deploy 648 satellites in orbit, and about half of the deployment has been completed. Telesat, a Canadian operator, is planning to build a satellite called Lightspeed Satellite Internet, which consists of 298 satellites. Spinlaunch focuses on building alternative launch systems, while INMARSAT, Intelsat and Hughes network have ready-made satellite communication networks. < / P > < p > companies submitted documents on Thursday to apply for the number of satellites to be launched: 7774 for Amazon, 13620 for Astra, 5789 for Boeing, 198 for INMARSAT, 216 for Intelsat and 14 for Hughes network 40, 6372 oneweb, 1190 spinlaunch and 1373 telesat. < / P > < p > SpaceX under Elon Musk has deployed 1740 satellite link broadband satellites, but it is not among the latest batch of applicants. The FCC previously authorized SpaceX to launch about 7500 V-band satellite link satellites, and the company is applying to launch its "Gen2" The plan of nearly 30000 satellites in the system. < / P > < p > Why do companies pile up to submit applications? < / P > < p > it is unclear how the FCC responds to the influx of applications and which applications have been authorized to launch. Armand musey, President of summit Ridge Group, which specializes in consulting the valuation of Companies in the telecommunications and satellite industries These companies have the same motivation, says Mr. Mussi "Everyone wants to make a bet in this field. One way is to apply for the construction of Satellite Internet, and then go down this road. They will figure out how to deploy it, or they may make some changes to the original application. But if you don't act on the application, you'll give up your qualification to participate in the space feast." < / P > < p > in addition, Mussi also said that the historical role of the FCC in this regard is to analyze whether the applicant has correctly submitted documents, rather than "make a judgment based on the evaluation of the business plan" Or < / P > < p > a major problem brought about by the potential jump in the number of LEO satellites is the increased risk of collision and the generation of new space debris. These companies' proposals include manipulation systems and the use of the atmosphere to burn down scrapped satellites as a way to combat these risks. They also propose to deploy satellites in a wider altitude range, from 600 km to 10000 km from the earth Higher place. < / P > < p > Musi said: "Space debris is one of the increasingly important problems that the industry needs to face. If there are too many satellites over the earth, they begin to collide with each other, which is likely to have a chain reaction. People are worried about the survival threat posed by these satellites, but except for individual governments, there is no authority to supervise and ensure that satellites are launched in a responsible manner." < / P > < p > V-band challenge < / P > < p > satellite communication systems traditionally focus on lower frequency spectrum, such as C-band, but have increasingly developed to higher frequency band. However, it is more difficult to use such as Ka band, Ku band and now V-band. Musi said: "These frequency bands are difficult to use, but they can obtain more bandwidth and throughput, and the technology of using V-band is becoming more and more feasible." < / P > < p > however, Mussi acknowledged that the business model is "still uncertain", and the market focus, potential broadband speed and more details are reflected in "a variety of different space Internet proposals". For now, V-band "It's essentially an asset. You can get business through trading." < / P > < p > queerty said that using V-band involves "the bottom line of physics". He said: "the higher the frequency band you use, the more vulnerable you are to weather and other problems that reduce signal strength." < / P > < p > this means that the company needs better antennas, more powerful satellites and improved processing algorithms to provide V-band services to consumers. However, the company has gradually overcome technical barriers, which increases the potential use of V-band. < / P > < p > Mussi said: "With the passage of time, the whole history of wireless communication, whether satellite or ground, is a process of slow migration to higher frequency band. The question is: when can you reduce the price to a commercially feasible level?" < / P > < p > queerty also stressed that the lack of a strong supply chain is another challenge for companies wishing to build V-band satellite and ground systems. He said: "This process is expensive, is still at an early stage, and the source of supply is limited. I think companies trying to make these parts themselves will face major engineering challenges."
