First, from the network to understand the application scope of:
A, maritime satellite phone, maritime satellite has so far has more than 30 years of history, has always been A satellite network is deeply rooted in the hearts of the people, from the emergency department to the commercial network everyone is familiar with, the phone is generally calculated at $before, basic call will be more than $1.5, fax are $5 to 6 above, basic data bandwidth not only small but also expensive, relatively new product FBB Internet rate reached more than 400 K, but according to the flow of charge about $15, one million, the price does not poor, but maritime satellite do usually trustworthy product quality, are you department, but maritime words fee although expensive, but there is no monthly fee, and the period of validity, this can also be expensive, only A hand-held for maritime satellite Isatphone Pro cost is cheaper, estimate the maritime satellite companies want to popularization of his business.
B, iridium satellite phone: it is well known iridium feedings, the MOTOROLA information complete build his iridium plan, but always plan as change is big, because the money is too big, short, the United States to used for military, finally the United States department of defense for its pay, iridium for several years, the company also didn't disappoint, with its network coverage and stability, and firmly hold on the satellite voice market, like the land of high-end audio market are almost iridium, water, forest, fire, geological, public security, armed police, mining, seismological bureau in these industries such as it can shake, and no company at the same time, its mobile phones are also more expensive, but very substantial, durable, cost is a bit expensive, but a lot of industry customers still favours the iridium, seems to stability.
C, the eurostar satellite phone: the eurostar phone is "young", its network system is advanced, mobile phone is more compact and more color, is very fashionable, but it is also a synchronous satellite, mobile phone is small, then the antenna is small, then catch the satellite comparison test, but after once captured by satellites, call quality is good, the satellite network by Arab operations, management and service is very general, before now slightly improved, plus the coverage of some limitations, it fails to cover the world, but still no problem in China, less at sea. After before the phone is not cheap, now the price can be considered.
D, globalstar telephone: in China, is a flash in the pan, the China satcom, will be responsible for the China operation in China, but later satellite expires, unable to achieve coverage in China, now has no tidings.
E, yaxing satellite phone: the small satellite was in the Chinese market share is good, it broke the concept of the satellite phone is expensive by more than 8000 all the way to the later more than 4000, is a satellite on the network, in the Philippines, can basic coverage across China, its cheap prices also has been 0.25 - $0.35, but the quality is a bit poor, but at that time in the Chinese market or not less sales, maritime satellite haven't handsets at that time, the star was also fails to cover China, iridium satellite phones to around 15000, call charges to $1.49, then the globalstar despite but not sold in China is very good, the main mobile phone you is big, volume, price at that time about 10000 or so, the satellite life will eventually then found no sponsor, this is a maritime satellite handset market and want to development, took the stand, money is the legendary yaxing was taken over by maritime satellite, the details not too clear, maritime satellite try after water, introduced the Isatphone Pro handsets, the difficulty of it or a small antenna accept as far away as 40000 kilometers of the satellite signal, believe in maritime technology should be no problem, ah, pure voice let's choose iridium.
In the second place, from regional categories to recognize satellite phone
A, maritime satellite phone: like A satellite phone is born to ocean, first is to solve after the ship went to sea and the shore connection and distress alerting, established the United Nations international maritime rescue organization, however this is maritime satellite (INMARSAT) the predecessor of the company, so the maritime business companies don't better than the other satellite, is the ancestors of maritime satellite phone, but today A considerable share of the let's just say it, but it is not without pressure, its offshore business pressure is very big, profits from the voice and fax, as it had been before but today this two business can not meet the needs of merchant, who doesn't have the demand of the email, A short, A month, two months at sea, long is one year, two years on the boat boring lonely, crew online chat A day of what needs to be on the network, Marine VSAT monthly, it seems maritime satellite want to send A money also is not so easy.
, land satellite phone B: market is basically all maritime satellite 10 years ago, but with the development of the market and customer of this year, its market is iridium eating a lot of, this year also to share the eurostar, maritime satellite as an old brand also strive for the market, this is the acquisition of yaxing continued maritime only a hand-held Isatphone Pro comes in. Terrestrial satellite phones are divided into vehicle satellite phones, indoor satellite phones, satellite phone, why so points? Reason is the satellite phone or no signal inside the car, indoors is inch a director, some short-scale, its technology system lead to it cannot penetrate the cement or shade the building, in that it can't say it let's linkage and China mobile phones, they should be complementary, but by adding some auxiliary equipment, satellite phone still can be used in indoor and the car, let's have a look at how to use the below?
1, indoor satellite phone: because there is no satellite signal indoor, so the indoor generally unable to properly called satellite phone, so will lose the meaning of the satellite phone emergency, some manufacturers for satellite phones equipped with a set of desktop hands-free devices indoors, and equipped with a satellite antenna, the outdoors so satellite phones can be used in indoor, because of the added hands-free devices, called satellite indoors as ordinary call so convenient, still can have a ringing shout trendy, from the maximum extent to meet the emergency, the purpose of the on duty. The satellite-based mobile phone hands-free devices is divided into about maritime dedicated, iridium is special and the eurostar is special, imported and domestic:
A, special maritime satellite phone Isatphone Pro.
