Satellite Internet access, we use it?-Satellite Internet, satellite networks, broadband satellite-IT news Satellite Internet access, we use it?
Abstract: in the relatively backward regions, cannot be due to the deficiencies in the layout of the broadband Internet access via satellite Internet access means access to the Internet is a complement.
United States media reported that Google plans to spend up to $ 3 billion to build satellite systems for global provides Internet access in remote areas . Satellite Internet access sounds very "tall", and Internet access that would be popular in the future, please?
Satellite Internet access can provide users with a point-to-point communication services, this service works like this: first divided into several satellite channel, separately for different files and information. Provision of satellite broadband services to businesses, hire one or several satellite operators satellite channel, then using surface station data sent to the user on the channel, then through the satellite to broadcast to forward these data to a receiving station on the ground, then enter the user's Terminal.
Now the country has achieved full coverage of satellite broadband, users can apply to the related operating companies services. But regardless of the look from Internet access rates and prices, advantages of satellite Internet is not very big.
In 2010, the media had to test the satellite Internet, test subjects is the IPSTAR broadband satellite. His highest rate of 8Mbps downlink and uplink speed of 4Mbps. This rate at the time, there might be a certain advantage, but now, as opposed to fiber optic Internet access, have lagged behind.
Costs, a 2013 data shows, if you buy the Terminal way, IPSTAR satellite broadband basic version 1M 596 Yuan/month, need Professional Edition 2M 996 Yuan/month, Business Edition 4M 2796 Yuan/month. If you use a pre-paid costs even higher.
So this kind of Internet connection whether universal? Listen to expert opinion.
Ma Jihua:
, Focusing on broadband in remote areas cover
In different parts of the Internet are different. In some backward areas, causing no Internet access due to deficiencies in the layout of the broadband via satellite Internet access means access to the Internet is a complement.
Zhongwei puxin of satellite broadband providers such as intra-company specifically rural informatization solution was made by reducing the satellite resource access and station construction costs, rural users are relatively inexpensive Internet-oriented services.
Second, common Internet technology is very mature
Motorola had to spend large sums to implement "Iridium plans" intended by building a satellite network to provide wireless communications services. However was built because of the traditional phone network Terminal has huge popularity, Iridium service is interested, ultimately failed.
At the national level, three major telecom operators have already built up an extensive broadband network, broadband coverage in the country is very high, satellite Internet access is not necessary.
Third, the focus of the satellite services are not on broadband
Broader applications of satellite services, including emergency communications, marine communications, industry network, but are generally aimed at the enterprise, government authority, consumer-oriented Internet service percentage was not high.
And satellites are relatively scarce resources, companies such as Motorola and Google, will need to invest heavily in the construction of the new satellite, such cost is huge. At the national level, most satellites that are already being used for military purposes, civilian-oriented level is not high.
