Today, in the progressive XXI century, innovative Information Technology and the Internet occupies a special place in human life. Here and work, and communication, useful information and entertainment, the possibilities of the global network are endless. It is hard to imagine that until quite recently the Internet was created only as a small social network for students of an American university.

Currently, the Internet via a satellite dish (VSAT) is characterized by mobility and speed of connection, reliability and independence from terrestrial communication channels, the satellite transmitting the signal eliminates the occurrence of any malfunctions.

A distinctive feature of the double-sided satellite internet is a high-tech signal transmission and as a result high speed work, which allows you to successfully use this method of connection for doing business, training, communication.

The advantage of two-way satellite Internet is a fairly wide satellite signal coverage area, so the Internet in the area works as well as in a large city. For example, if you need to go to friends or relatives in a remote village or village, then this will not affect your daily activities that require constant access to the network. It is also worth highlighting the ease of connecting via satellite and the availability of favorable unlimited tariffs for satellite Internet.

Today, satellite Internet in the region is a list advantageous offers and innovative solutions, the ability to create a remote video surveillance system and organize uninterrupted, reliable operation.

Satellite internet prices, tariffs

Our company provides services and equipment of the following providers of two-way satellite Internet

We offer the implementation of two-way broadband access to the global Internet network using a subscriber set of Gemini satellite equipment manufactured by Gilat Satellite Networks, or a Hughes HN9200 satellite router (Surfbeam-2 or Newtec) and a Prodelin receiving and transmitting antenna (Viasat or Newtec). Mounting and installation are carried out in short time, on reasonable price, but the cost of the work performed does not include travel, transportation costs and the cost of other types of work.

To determine the possibility of connecting satellite Internet in the place you need - use our new service- Departure to the Customer to check the possibility of installing a satellite set. The cost of this service is 5000 rubles.

Required equipment and services:

Our company offers you the most modern technologies to create Internet access at a high level, with a good data transfer rate.

It is worth noting that our service has significant advantages over other types of Internet access offered to residents of the region, for example: GPRS, EDGE and CDMA, which have many limitations, failures and connection difficulties.

We offer you to buy two-way satellite Internet - a modern and high-tech solution for cottages and country houses located far from terrestrial communication channels!

For more detailed information about tariffs and prices for satellite Internet, please contact our support service by phone posted on the site.

It is gaining momentum in our country more and more. Many hosting companies satellite television, as an accompanying or additional service, they also offer the Internet via a satellite connection. Such popularity is quite understandable: this "variety" of the Internet has a number of advantages that we are beginning to appreciate more and more.

What exactly are we talking about?

Considering the advantages of such an Internet, we first of all talk about its accessibility. Communication using a "dish" can be easily organized at any point related to the satellite coverage area. That is, you can have satellite Internet at home even where there is no way to run a cable or telephone line.

Another significant advantage of such a connection is the high speed at which data is transferred, combined with enough reasonable price traffic units.

There is only one main problem here - in order to transmit return data from the user, satellite Internet requires a separate channel - terrestrial (if we are not talking about a two-way option). As a rule, such transmission is carried out using ADSL, GPRS or dial-up technologies.

Perhaps, the disadvantages should also be added to the dependence on the weather and the possibility of signal delay. But if there are no other options, the Internet through a satellite dish becomes indispensable. After all, today it is simply vital for many people. For example, satellite Internet in a private house located "far from civilization" will have to be carried out one way or another, if without the Network you cannot imagine a full life.

What equipment is needed

If you decide to bring satellite Internet to a private house, you will need to purchase, in addition to the dish itself, also a cable for it, as well as a DVB receiver, a computer DVB card. And do not forget about the converter and mounting bracket.

In addition, stock up on F-connectors - they are used to connect cables to converters. If the whole plan self-installation and dish connection, don't forget the heat shrink needed to insulate the F-connector cable, and stock up the mounting anchors for the bracket.

Setting up the connection

So, we begin to equip satellite Internet with our own hands. The DVB receiver needs a properly tuned satellite. First of all, you need to set up a terrestrial channel according to the requirements of the provider and technical features connections. For insertion, you can use any of the free slots on the computer, after which the the right drivers, which are available on the included installation disc.

You will learn how to properly configure the driver you installed from the disk from the attached instructions. Your task is only to carefully follow it step by step. After installing the drivers, create network connection. It is advisable to download the GlobaX program from the network. If this item causes you difficulties, contact the place where you bought the satellite equipment.

It would seem that connecting and setting up satellite Internet with your own hands is very difficult. But in fact, following the instructions included in the kit, you can do everything quite sensibly and quickly. In addition, many vendors of equipment for such Internet now offer the service of its installation and full customization. This condition should be specified when making a purchase.

We mount satellite Internet with our own hands: a sequence of actions

Most individual users are familiar with only one-way Internet access through (it is also called asynchronous or asymmetric). To have full access, you need to organize a "ground" line (it is needed so that you can transmit the outgoing signal), and for the incoming signal you will need to establish a connection between the dish and the satellite. And connecting satellite Internet with your own hands is a very real task.

Having acquired a converter, cable and DVB, we get down to business. At the first stage, it will be necessary to connect to the World Wide Web using any type of communication. This can be done using 3G, GPRS or Dial-up modems, as well as using a dedicated DSL line (if any).

We collect data

Going online, find as much information as possible about providers that offer Internet through a satellite dish. You will have to study and systematize for yourself the names and locations of the satellites they use, compare transponder parameters and refine maps of the area covered by the signal. Be sure to check if your address is in the zone where the signal is caught.

As a result of this information research, you have in your hands a list of providers suitable for those living specifically in your area, with all the conditions and technical characteristics. From here, you can choose one.

Do not forget that for high-quality satellite signal reception, the antenna should not be covered by any obstacles in the form of houses or trees.

We finally decide

To find out if it is possible for you to receive a signal from the selected satellite, install the Satellite Antenna Alignment program (it's free). The coordinates of the satellite itself are entered into it, then yours - houses and settlements. The program will calculate the location of the satellite relative to your point - the angle of elevation, azimuth, etc. Using these data, once again check the presence or absence of obstacles.

If you have the ability to receive a signal from different providers, the final choice should be made by comparing their rates.

In addition, the required antenna diameter is important - this parameter is contained in coverage maps, as well as the type of convector (C or Ku bands), it depends on the signal frequency. When buying a network card, do not be too lazy to compare the characteristics of all commercially available options to choose the most suitable one.

We put the antenna and check the signal

At the next stage, we proceed to the installation of equipment. Having dealt with this, we insert a network card into the computer slot and install it software. Having picked up a suitable place (so that the selected satellite is available), we install the antenna there. Then we fix the convector on it and connect it to the network card via a cable.

The next step is to check the satellite signal. Tuner program network card input of its parameters - frequency, speed, polarization and FEC (information redundancy coefficient) is provided. The antenna must be oriented exactly in the direction of the satellite, this is done using the same free program.

If everything is done correctly, the signal from the satellite should be fixed by the tuner of the network card. How exactly to work with a specific tuner program is indicated in the user manual for the network card.

Completion of the procedure

Having received a signal, you can go to the website of the provider of this satellite, register as a client and subscribe. At your disposal will be Personal Area with all the necessary technical information- IP addresses, connection type options, payment methods, etc. By choosing the option that suits you and paying for the service, you can enjoy access to the World Wide Web via satellite.

Practical note: when choosing a satellite, look at what it broadcasts from television broadcasts. The best choice would be to get Internet and TV "in one package".

About antennas "Tricolor"

Many people are wondering if it is now possible to connect satellite Internet through Tricolor and how to do it. Unfortunately, on this moment this is not possible. Services provided under the brand name "Tricolor-Internet" are no longer being carried out - since March 2012 their provision has been suspended.

The company's management explained this by the small number of subscribers using this service (only about 0.1% of the total).

Maybe in the future this decision will be canceled as the company announced its intention to completely revise the strategy. A variant of two-way Internet via satellite is possible. Previously used equipment was distributed to provide services demanded by customers.

We organize two-way satellite Internet

If you want to do away with telephone lines and optical fiber forever, then you need to take care of providing a two-way type satellite communications(two way). This connection is symmetrical and is based on forward and backward signal transmission exclusively via satellite.

In this case, the antenna should be purchased in the Ku-band and having a diameter of 1.2-1.8 meters, while with a receiving LNB unit and a transmitting BUC. There are no other hardware restrictions.

It may seem to someone that equipping two-way satellite Internet with their own hands is too difficult task. In fact, it's quite simple.

Fixing and orienting the antenna

The antenna is assembled strictly according to the attached instructions. The place for fastening must be prepared in advance. It is important to determine which position of the antenna will be correct. It depends on the angle of the terrain, the direction in which the satellite is located, the distance to the existing obstacles and the load created by the wind on its mirror.

To do this before mounting, use some other satellite system (eg television).

With the help of the smwlink program you installed, the antenna is oriented to the south. Having fixed the plate vertically, we connect the speaker with the sound card.

A program that allows you to determine the signal level - Fast Sat Finder. With its help, by rotating the antenna, find and fix its maximum level.

Setup and testing

Then connect a computer (laptop) and install desired programs and drivers.

If you are going to connect to the satellite using desktop computer, you will need to buy and install a DVB card. For a laptop, you should get an external DVB device.

When setting up the antenna, test it with a computer. This process is quite long and laborious. Even if there is no interference on the screen, this is not a guarantee of high-quality data transfer. Achieving stability in your network is not so easy.

After setting up the antenna, start connecting to the provider. The procedure in this case is completely similar to that described above - we go to the site of the selected provider, submit an application, pay.

Results

Thus, we see that connecting two-way satellite Internet in terms of equipment is not much more difficult than the so-called one-way - one-way (using a converter amplifier). But the disadvantage of the latter is in a lower speed compared to a symmetrical connection.

Of course, it is quite possible to install and configure any equipment by professionals, but this also has its drawbacks. We are not talking about additional costs. But sometimes you will not always be able to figure out the quality of the services provided, and many of these tuners work with the help of just a household receiver, which guarantees almost nothing.

Many people, not at all specialists, quite successfully set up two-way satellite Internet with their own hands and never regret it later. So the choice is yours.

The article deals with the organization of two-way satellite Internet. Another name is duplex, synchronous. Geostationary satellites are used to operate such a system. This is a satellite located at an altitude of 35768 km, its orbit (geostationary - GSO) lies in the plane of the equator, while the angular velocity of the apparatus is equal to the angular velocity of the earth's rotation. Thus, it is always located above one point of the surface. This allows you to use fixed (fixed) antennas for transmitting and receiving a signal from a satellite, which simplifies the process of information exchange itself. The position of the satellite is constantly corrected with the help of sustainer engines. To survey the entire surface of the earth, theoretically, 3 such satellites are enough, but guaranteed communication is carried out only in a 40-degree band on both sides of the equator. Communication up to 75-80 degrees is possible and carried out, but it encounters certain technical difficulties. For Russia, this is the Arctic.

The figure shows the Internet coverage area of ​​​​two satellites:

Russian "Yamal";

Foreign «IntelSat».

As you can see, satellites provide communication for almost the entire territory. Russian Federation, except for Chukotka, and also capture part of European and Asian countries

Compared to cable lines, two-way satellite Internet has a number of advantages:

Continuous communication, since the satellite and antenna are stationary relative to each other;

Independence from terrestrial cable and radio lines;

Coverage of a large surface with only three satellites;

There is no need for inter-satellite communication, as in low-orbit systems, where satellites exchange information.

There are also disadvantages in the operation of two-way satellite Internet:

The high cost of the satellite and receiving stations. This is determined by a large distance from the satellite (about 36,000 km) and, as a result, a low signal level.

Delay in signal propagation. Considering the radio wave propagation speed and distance, the delay time is about 0.12 seconds one way, and the total response time is about 0.8 seconds. This is acceptable for TV and radio broadcasting, but not always for the Internet, and gamers need to forget about fast-paced online games.

Sensitivity to weather conditions (heavy rain or sleet with strong winds). This sometimes increases the delay time.

The principle of operation of two-way satellite Internet

In the case of synchronous Internet, the satellite operates in the receive / transmit mode. The request from the client is transmitted to the satellite and then to the receiving station (provider), which sends it to the Internet. Having received the necessary data from the requested site, the provider transmits the information to the client via satellite. The exchange is carried out on the microwave in the Ku band. Operation speed: up to 2 Mbps when transmitting and up to 8 Mbps when receiving information. Satellite two-way Internet client ground stations are called VSAT (VerySmall ApertureTerminal). VSAT stations can be fixed or mobile. The latter are widely used in the Ministry of Emergency Situations, on cars, ships, aircraft, etc.

Equipment, installation and configuration, tariffs.

Many companies are involved in installation and configuration. One of these is RuSat, which has been operating in this market for more than 10 years. The company has a transceiver teleport equipped with Ø9.15m antennas, powerful transmitters, backup power, etc. The basis is the Yamal satellite (Russia) and foreign IntelSat.

Below is a list of equipment supplied by the company for the operation of satellite Internet in two-way mode:

1. Antenna Ø0.75m with automatic guidance.
2. 500 or 800mW transmitter.
3. iLNB converter. Converts the signal from the modem to the Ku band (reception, transmission).
4. Modem with power supply.
5. Equipment for antenna orientation to the Point&PlayTM satellite.
6. Cables with connectors. Ethernet (2 m, RJ-45) and two Tx and Rx cables (30 m, F-type connectors).
7. Antenna support (option).
8. Documentation.

A subscriber can connect at tariff A (more than 1350 rubles) or B (less than 1350 rubles). If necessary, it is possible to connect to a local network via a cable line or Wi-Fi.

Two-way satellite Internet is the only option when there is no possibility of connecting to a high-speed cable line or radio communication systems. These can be dachas or cottage settlements, remote villages, mobile objects, etc.

The combination of two-way satellite internet with local networks(cable or wireless) allows groups of users to connect to the network.

Satellites provide continuous round-the-clock communication throughout the covered area.

VSAT equipment for organization of two-way satellite communication

When answering the question, what is two-way satellite Internet, it is logical to first answer the question - what is one-sided. In most cases, two-way communication is required for effective operation, however, one-way satellite Internet, namely the reception of data via satellite channel, can be useful when the user has the ability to transfer data in some other handy way.

Unlike one-way, it allows you to exchange information over a satellite channel in both directions, while the terminal works for receiving and transmitting, as a rule, at different speeds. The data rates received and transmitted by the system are indicated in its technical specifications and should be taken into account by the user when choosing equipment based on the specifics of the work.

Two-way satellite communication is a relatively expensive method of communication, therefore it is currently used mostly in professional segments, where the continuity of high-quality communication ensures the viability of the main line of business. This is especially true for hard-to-reach areas that do not have the appropriate infrastructure, which can also include maritime spaces, where ships crossing them are left alone with the elements, and only two-way satellite communication can provide a high level of security.

Satellite equipment has become widespread due to the implementation possibilities two-way satellite communication using satellite equipment of relatively small size and high performance. At the same time, the very principle of organizing two-way communication via satellite has features that are important to know and take into account. For example, the satellite equipment standard unambiguously defines the circle of people working with it. satellite operators and the services they provide. The second is about two-way satellite communication in general - a characteristic signal delay (of the order of tenths of a second), noticeable when organizing satellite IP telephony, in dynamic computer games and other services that require high-speed internet.

To implement the task of two-way satellite communication, the most attractive equipment is VSAT Ku-band. The frequency range directly affects the size of the antenna fabric, so the previously widely used C-band is not suitable for compact solutions. Antennas VSAT Ku-band have a diameter of about one meter, and in the European segment - Ka-band - up to 80 cm. VSAT The system includes two high-frequency units with the commonly used names BUC and LNB, which are responsible for transmitting and receiving. Blocks are installed on the irradiator. double sided satellite modem is the main switching device between VSAT antenna and user's computer.

When choosing VSAT equipment two-way satellite internet it is important to consider which provider you will be working with and inquire about the quality of their services. Subsequently, if it becomes necessary to change the provider, the issue can be resolved by replacing the high-frequency units and the modem, which in some cases can be provided by operators for free. This is quite logical, does not contain a catch and fits well into general approaches market: at one time, Internet providers provided household telephone modems for free use.

With regard to the issue of delays, it must be understood that in this segment the highest value is the quality of information transfer, and not the costs associated with it. Obviously disgruntled gamers are not target audience these services, but only indirectly use them, for example, as passengers on a cruise ship. This category of customers only needs to be patient until the development satellite technologies two-way communications compensate for their whims.

Using two-way satellite Internet, the user gets access to all his resources: streaming video, social networks, messengers, e-mail, corporate network etc. Independence from ground infrastructure is a huge advantage satellite systems VSAT providing two-way internet at any point in the coverage.

Equipment two-way satellite internet it is necessary to choose in multi-brand stores, since on such sites it fairly competes with each other and is not tied to providers promoting their services. Online store "" offers equipment VSAT leading world manufacturers, with which you can get high-quality two-way satellite communication.

Satellite equipment for two-way Internet communication is a high-tech solution and requires high-quality installation, commissioning and maintenance. Engineers of the company "" offer a full range of services, from consultations on choice VSAT and ending with a turnkey installation. Two way satellite Internet implemented with the help of the company's engineers " Marinec” and the equipment supplied by it is a long-term, high-quality solution that will reduce your dependence on other forms of communication and provide you with new opportunities for continuous communications that correspond to the current level of global technological development.

In this article I will try to conduct a comparative analysis of kits for two-way satellite broadband access service or, in simple terms, satellite Internet, in order to try to answer the question: Which satellite Internet to choose?

I’ll make a reservation right away that this comparison is from the point of view of an installer and a private user, and not a technical specialist or an IT specialist. This material will be of interest to private users and small organizations (farmers, shops, small firms, etc.) located in the European part of the Russian Federation. For large companies with a large number of subscribers and huge traffic, completely different offers are provided, which we will not consider in this publication.

Who and how will we compare

To date, there are 3 main players in this field:

• KiteNet (KiteNet).
• Eutelsat Netvorks (Eutelsat Networks), which works for us under the Tricolor brand.
• And, the so-called Ka-Sat (Ka-Sat) from Altegro Sky (AltegroSky), Raduga-Internet and several other operators.

You can also find Hughes Jupiter kits (Hughes JUPITER), but this is already a more expensive solution and it is more relevant for the eastern regions of the country, so we will not consider them in this review.

I will compare the proposals of the above-mentioned review participants according to 6 parameters, based on my own experience and recalling our customers:

1. coverage area.
2. Equipment set.
3. Cost of equipment.
4. Installation, configuration and registration.
5. Rates and speed. For comparison, let's take 10GB of prepaid traffic.
6. Ease of purchase and scope.

It is clear that any of these points can change at any time. For example, one of the operators can reduce the cost of traffic (dreams-dreams), and someone will offer more affordable equipment. So, I will make a reservation that the data below is relevant at the time of writing the review, and this is March 2017.

Overview of satellite internet Ka-Sat

Let's start with Ka-Sata, because. this proposal appeared on the domestic market earlier than the other two.

1. Tricolor Internet coverage area

The service is provided from the Express-AMU1 satellite (Eutelsat 36C) at the position of 36° East. Thanks to this, Tricolor satellite Internet covers the entire European part of Russia, as well as most of Eastern Siberia. In addition, this is the highest hanging satellite for us, and, therefore, the most convenient for reception (especially in the European part of the country).

Here five.

2. Set of equipment Tricolor Internet

The kit is the most compact of all and the most modern of all monitored. The equipment is manufactured by the well-known Israeli company Gilat Satellite Networks. For connection, a set of satellite equipment Gemini-i is used, consisting of:

• Antennas with a diameter of 0.76 m with a mounting and guidance system
• 2 Watt transceiver with built-in audible fine pointing indicator
• satellite modem

Unfortunately, the bracket is not included. In general, a good quality kit, but still slightly inferior to the Ka-Sat.

Four due to the lack of a bracket.

3. The cost of Tricolor Internet equipment

The price for a set on the market is not small - from 24,000 to 27,000 rubles. The highest of all three operators. Someone, perhaps, here will draw an analogy with the Tricolor TV satellite television set, which has never been famous for its attractive cost. Well, what can I say: Tricolor is a brand, and you have to pay for the name.

Because price the cost of the kit is the highest of all, then we will supply top three.

4. Installation, configuration and registration Tricolor Internet

Installation is almost the same as Ka-Sat, but there are several technical aspects that make assembly and installation more complicated. Most likely, you will have to use the services of specialists.

Four.

5. Tariffs and speed of Tricolor Internet

As for the speed of work, Tricolor simply has no competitors here! 40 Mbps receive and 12 Mbps back. To date, no one works faster! Even the newfangled mobile networks LTE is far from being able to offer such speed everywhere.
