Wireless Wi-Fi and satellite Internet - what role can they play in our lives?

The modern dynamic world sets tasks for us and is not interested in whether we have a weekend, where we are and whether we can now take on their implementation and keep abreast of events. Only fast satellite Internet and Wi-Fi can provide the necessary freedom of action.

If you are in the country, live in a country house, or sail on a yacht. If you are not satisfied with the unreliability of the mobile Internet. If you want to sit comfortably in the garden with your laptop to do your business or just check out the latest world news. If you don't want to dig into the walls of your office to run the ubiquitous cables. If you are interested in inexpensive unlimited Internet... By combining it in your home or office satellite internet and wireless Wi-Fi, you can easily fulfill any of these wishes. Let's look at the benefits that satellite Internet providers provide to Internet users:

• Freedom of access. Thanks to satellite Internet, you get access to the World Wide Web from anywhere in the world, and by ordering unlimited Internet, which is very affordable, you can no longer think about restrictions. Wi-Fi will allow you not to look for where to plug the wire, but simply turn on your laptop or PDA and use the Internet and local network;
• Free phone number. If before connecting to satellite Internet you used a modem connection (dial-up), then this will be a huge advantage for you, and if you decide to install Internet via satellite in the office, your clients will be able to reach you at another telephone number;
• Installation, connection and configuration of satellite Internet and Wi-Fi are very convenient. Internet via satellite and wireless Wi-Fi communications allow you to not depend on wires - the Internet and network will be available to you anywhere in your home or office within a radius of more than one hundred meters from the access point. And you no longer need to think about how to organize a local network without making holes in the walls - all your computer devices will be connected to fast, high-quality and inexpensive satellite Internet and to each other. Installation and connection of satellite Internet and Wi-Fi passes without laying meters of cable using just one set of satellite equipment and one set of Wi-Fi;
• Speed. Internet via satellite and wireless Wi-Fi provide its users with high access speed, allowing them not to wait for hours while a file is downloaded or a large letter is sent, and fast unlimited satellite Internet allows them to completely forget about kilobytes and megabytes.
• Reliability. High reliability of both the Internet via satellite and Wi-Fi ensures continuity and quality of communication;
• Connect anywhere. Fast and high-quality satellite Internet and Wi-Fi connections can be installed where another connection is simply impossible, because cables cannot be laid;
• Safety. If you are just chatting, that’s one thing, but what if you need to transfer data on which your career may depend? Or even the fate of the company? Satellite Internet and Wi-Fi are securely protected from traffic interception and are available only to their owners and users;
• Availability. Satellite Internet providers offer tariffs that make fast satellite Internet (including satellite unlimited Internet) available not only to companies, but also to individuals. To connect to a Wi-Fi wireless connection in a cottage, apartment, office or any other room, an access point and equipment, which is very often already installed by default in modern laptops and PDAs, is sufficient;

The symbiosis of wireless technologies: Wi-Fi and VSAT (wireless internal network operating through the use of broadband radio channels + two-way satellite Internet) has significantly expanded the horizons of data processing and transmission over long distances. The main advantage of this fusion of technologies is determined by the complete refusal to use wired communication lines, which allows access to the most remote residential or industrial facilities. At the same time, the quality of communication and the speed of exchange of data packets is not inferior to wired technology, and in some cases exceeds it. If in the second case the speed is hundreds or thousands of kilobits per second, then for Wi-Fi 50 megabits per second is not the limit.

Satellite Internet is somewhat slower than a wireless LAN system due to the long distances the signal travels. Connecting to symmetrical satellite Internet gives you access to the following services:

Wireless Internet access: benefits

• First of all, access to the Internet directly, and the exchange of information between the satellite platform and the DVB card (a substitute for a modem for receiving a signal from an antenna) in your computer occurs at speeds of up to 2-4 Mbit/s
• The ability to use IP telephony, which ensures reliable communication even in areas where there are no landline communications from telephone companies
• Video conferencing has recently been widely used for remote meetings and negotiations between large business and industrial centers. The satellite signal provides high-quality video images transmitted in real time
• Unlimited viewing of satellite TV programs, connection to public radio channels

When used together with Wi-Fi technology, the satellite signal reception area increases to hundreds of meters. This creates a kind of connection area to a hot spot system (wireless local network station with a broadband radio signal), from any point within the coverage area of ​​the Wi-Fi terminal.

A flexible tariff schedule will allow you to choose the most convenient traffic in terms of cost and access speed. With a fairly low price scale and high quality of communication, few terrestrial dial-up Internet providers can compete confidently with satellite Internet.

Your unlimited connection with the world is in your hands. It is in our power to provide you with it.

Our recent review of StarBlaizer's satellite Internet access seemed somehow incomplete because it didn't include the magic word "router." And I really want to organize a simple and comfortable connection for many devices at home or in a small office! And here StarBlazer offers us a series of firmware developed for popular routers. You will, of course, need a StarBlazer SB340-USB receiver and something else. So, first things first.

Competition participants

This development, as you might guess, was based on a wonderful scheme: you update the router with new firmware, connect all the components to it, it configures connections and tunnels itself - and as a result, you get the Internet throughout the entire network with automatic distribution of IP addresses. This is exactly how we would like to see the operation of our complex system, which involved a router, a USB modem from, a USB hub with external power from KS-is, satellite receiver StarBlazer SB340-USB, as well as a roof-mounted 90 cm antenna with LBA and 20 meters of cable with F-connectors.

We have had most of the devices since the last review. Only the D-Link DIR-320 was invited to visit - before that it had quietly and peacefully distributed the Internet at the dacha. By the way, Asus WL-500G Premium V2, TP-Link TL-WR1043ND, D-Link DIR-320- these router models can be turned into the so-called SB-Router.

SB-Router | Firmware procedure

Transformation procedure D-Link DIR-320 V SB-Router described in detail. If you choose another model out of three possible ones for firmware, there are no problems - all steps are explained in detail and step by step. It is also taken into account that the D-Link DIR-320 may “not recognize” the proposed firmware SB-Router for the "native" one and you will have to use the firmware method with manually disconnecting/connecting the router's power supply. A convenient utility is offered to start the firmware process flash_dlink.bat. It would be great to add a file to the software package tftp.exe- What if someone doesn’t? If you don't have it, download it.

SB-Router configurations

Satellite router SB-Router can operate in one of four configurations:

1. Ethernet router for home network with WiFi support. Performs virtually the same functions as the “basic” models of home routers.
2. 3G router for home network with WiFi support. Allows you to connect to the Internet via a 3G modem not only a single computer, but also an entire home network, both via Ethernet and WiFi. To connect to a cellular network, use a standard 3G modem or even a cell phone with a USB port.
3. Satellite router for a home network with WiFi support, using an Ethernet request channel. Allows you to connect to satellite Internet StarBlazer home network both via Ethernet and WiFi, without using a dedicated computer.
4. Satellite router for a home network with WiFi support, using a 3G interrogation channel. Allows you to connect to satellite Internet StarBlazer home network, both via Ethernet and WiFi, without using a dedicated computer. To connect to the cellular network, use a standard 3G modem or a cell phone with a USB port.

Our choice is a satellite router for a home network with WiFi support, using a 3G interrogation channel. As a matter of fact, the satellite part and the 3G interrogation channel have already functioned successfully based on the results. All that remains is to add a router with the appropriate firmware to them.

SB-Router | Assembling the circuit

Router D-Link DIR-320 has only one USB port, which we expanded with a USB hub with external power from KS-is. In principle, the circuit starts without additional USB power, but the modem clearly does not have enough power and an additional power source is only beneficial. The USB port in our case carries a double load: the satellite receiver communicates with the router through it StarBlazer and 3G modem.

StarBlazer SB340-USB satellite receiver, KS-is USB hub, 3G modem from MegaFon and D-Link DIR-320 router

We connect one of the LAN ports of the router with a cable to the RJ-45 port of the computer, having previously set the automatic selection of the IP address in the network settings. All these nuances are described in detail in the proprietary firmware manual SB-Router. If the antenna is tuned to the satellite (like ours), then everything is ready and after turning on the power, all that remains is to configure the software.

Setting up SB-Router

The setup consists of entering your registration data in the appropriate fields of the interface without changing other parameters. If everything is done exactly like this, then the system works. It is not by chance that we draw attention to this fact. The fact is that after loading the configuration file, IP addresses that seem strange at first glance will appear in some fields. There is no need to touch them: we will only add the password, name and MAC address for the satellite receiver.

Entering registration information to configure SB-Router

The firmware is a complete software for the router, built on the basis OpenWrt, with a large number of sections that expand the functionality of the router. Experienced users will be able to obtain a variety of statistical information about system operation, etc.

SB-Router software interface

Those who see nothing more than letters and numbers in the settings lines can rejoice in the fact that in the firmware description StarBlazer provides all the main screenshots and indicates the lines that need to be modified.

It’s good that the 3G modem does not have to be configured - the system takes care of us. In fact, we didn't have to enter a single number or letter in this section. But it’s worth taking care of a place where GSM reception is best. Our experience shows that the signal from the satellite is good and powerful, which cannot be said about mobile communications, which are subject to significant weakening of the signal and even its complete loss (and this is in Moscow!). And if there is no thin 3G thread along which data runs away from us, then the wide channel towards us from StarBlazer, alas.

SB-Router | Performance Comparison

Important point: by launching SB-Router, we gained in the convenience of organizing access to satellite Internet, but lost the ability to use an accelerator Slonax 3G. The technology for creating the connection itself does not provide for its use. However, new firmware options are already being prepared, for example 04rc6, which shows the intentions of the developers to provide users with technology SB-Router possibility of using one of the accelerators. At least, a template for its configuration file has already appeared.

Blank for accelerator configuration in SB-Router software

Without the use of an accelerator, achieving maximum speeds will not be easy. Our tests without an accelerator show very average performance, which is enough for web surfing, but not enough for retrieving large amounts of data.

The ability to watch digital satellite television in different places in an apartment or house requires labor-intensive networking of several devices. Reason: Each television receiver must be connected to a satellite dish using a coaxial cable.

Elgato EyeTV streams four programs simultaneously to your home network

Such complex networking is already outdated: a few years ago a solution such as EyeTV Netstream from Elgato. The idea is as follows. The digital television signal is supplied to the home network through the server. After this, via LAN or Wi-Fi, which have become common in many homes, television signals are transmitted to the end devices. These devices include not only TV, but also computers, tablets and smartphones.

Until now, there was such a problem as the lack of a common standard among Elgato and other manufacturers for organizing the IP stream of “live TV”. Instead, they came up with their own streaming solutions. Thus, it was impossible to combine devices from different manufacturers, and even with adherence to the devices of one company, the results in most cases were not pleasing.

The FritzBox 6490 from AVM already has a built-in SAT-IP server

With SAT-IP, a protocol emerged (European standard 50585:2014), which even integrates HD television into the home network. Thanks to the Sat-IP standard, you can combine devices from different manufacturers. Elgato has a Sat-IP server called EyeTV Netstream 4Sat, which additionally has a built-in hardware transcoder. It does not matter whether a digital LNB device or a multiswitch is used (in an apartment building). For a cable connection in an apartment, a television program can be distributed on the network. Both options have a weakness: they only transmit unencrypted TV programs.

CHIP will tell you more about this technology.

Streaming on your home network

The name SAT-IP can be misleading, since the protocol is supported not only by satellite television, but also by cable and terrestrial television (DVB-C and DVB-T).

The central element in SAT-IP technology is SAT-IP server, often also denoted as DVB-IP converter. This server is located directly behind the television receiver and is connected, for example, to a digital LNB (Low Noise Block) of a satellite dish or to a multiswitch.

Several high-frequency tuners are hidden under the cover. Currently, SAT-IP servers with two to eight tuners are popular on the market. Tuners demodulate the television signal, which at the next stage is packaged into an IP packet and transmitted further.

Each tuner, according to the SAT-IP standard, can support both one client (Unicast) and simultaneously distribute a television program to several receiving devices (Multicast). At the same time, the Live-TV data stream remains untouched.

There are two servers that have a built-in hardware transcoder that expands functionality and is not a mandatory component of the SAT-IP standard.

In a home network, SAT-IP works using DLNA streaming protocol, divided into two layers: the media layer through which Live-TV data packets are transmitted, and the control layer through which devices request access. With SAT-IP, nothing happens until something is requested by the client.

SAT-IP technology does not require a complete upgrade of your home network. You can continue to use your existing satellite dishes. The central element of this technology is the SAT-IP server, which connects to the television receiver. This server receives the program and packages the television data into IP packets. It transmits them through the router to the network and then to devices via LAN or Wi-Fi.

If the client runs on the device, it searches the network for available SAT-IP servers. In most cases, servers and clients must have corresponding IP addresses. If the IP addresses match, server discovery should automatically work through SSDP (Simple Service Discovery Protocol), since each enabled server is registered with the network.

By the way, the SAT-IP standard by default provides for several SAT-IP servers on the network that do not conflict with each other.

If the client and server find each other, the clients can request streams. For this purpose, the standard provides classic HTTP or RTSP (Realtime Streaming Protocol) configured for streaming as protocols.

Through a playback request, the client requests a specific television program from the server. To do this, you just need to call the desired thread ID. If the ID is correct, then the transmission of RTP (Realtime Transport Protocol) packets begins.

For a SAT-IP data packet, the MPEG2/4 stream is packaged in the form of 188-byte fragments. Seven such streams, together with RTP, UDP and IP headers, form a SAT-IP packet of 1356 bytes in size.

SAT-IP transmits two types of data. At the control level are UPnP devices. Commands are sent via RTSP (Realtime Streaming Protocol). At the media level, the TV stream is transmitted via RTP (Real Time Protocol) or HTTP. Data packets are packaged and forwarded via UDP or TCP/IP protocols.

Data Decoding

The SAT-IP standard does not limit the quality of transmitted data. It doesn't matter whether the post-processing is SD, HD or 4K going to the TV receiver. In addition, SAT-IP is designed to transmit both unencrypted and encrypted programs.

To decode streams, the SAT-IP server or client must provide space for the connection interface. Via the connection interface module, the television program is decoded and can then be transmitted further to the network.

But, of course, SAT-IP will only work properly if there is a sufficiently high-speed network. For full retransmission, DVB-S2 needs to plan for 40 Mbit/s. If you need to run different programs through your home network in parallel, you definitely need a gigabit infrastructure.
