L-Band is the only frequency that allows a portable satellite antennas to deliver high-speed data over satellite. The good news is if one employs a few simple tricks while using a BGAN terminal, the cost of service can be drastically reduced. The L-Band has a very long wavelength and as such it has low effective bandwidth… or In other words, the amount of data that can be pushed though one L-Band satellite is much less than the Ku-Band or Ka-Band frequencies used by larger satellite dishes, such as iDirect, Hughesnet, Exede, and Ground Control.
Simply search for information for disabling auto-update on all programs that are running on your computer. For those that are running, turn off their background internet connectivity auto-updates, push notifications from the specific app control panel.
The good news is that the default configuration of many smartphones and tablets use significantly less data than laptops. For example, email programs will only download the headers of the email and only when you click on each individual email does the body and any attachment download. So, the two biggest uses of the Internet email and web browsing can be highly optimized for very low data use over BGAN. There are programs available that monitor your connection to the internet and will alert you when some program initiates a connection.
ZoneAlarm is a free firewall program that alerts you with a pop-up window — you select if you wish that program to connect or not. Many of our BGAN clients are most interested in using their email connection to transfer images and files as well as to communicate with their organization. By doing this, an email client will only download the tiny headers of each email and not its body or attachments.
Emails are read by clicking on them to start the download of that email. These may help. Smart devices can download the Opera Mini browser that has the wonderful feature of low-bandwidth configuration.
There are settings inside the Opera Mini browser that resample images and make them smaller. Meanwhile, VSAT, in most cases, needs separate contracts on different satellites and teleports to achieve global coverage. Fixed VSAT systems require a trained technician with a spectrum analyzer to aim and reach the peak of the terminal, and will require two people to assemble or move the equipment.
BGAN terminals are much smaller and include a rechargeable battery, so they do not need to be attached to a power source. In general, BGAN licenses are less expensive than VSAT licenses, but you should analyze your case with Network Innovations to get guidance on what to expect in the different countries where you need to operate.
Please leave this field empty. Check our help guide for more info. VSAT satellite technology: What is it and how does it work? Ka Band satellite frequency 25 July, Costs can be cut considerably, however, by optimizing your connected device. The primary reason BGAN service is high is because the terminal is transmitting to a satellite over 22, miles away using the L-band frequency.
L-band is the only frequency that allows a portable satellite antennas to deliver high-speed data over satellite. The L-band frequency has a very long wavelength and as such it has low effective bandwidth. In other words, the amount of data that can be pushed though one L-band satellite is much less than the Ku-band or Ka-band frequencies used by larger satellite dishes, such as iDirect, Hughesnet, Excede and even Ground Control line of satellite dishes.
Since the L-band effective bandwidth is smaller, the price for transmitting high-speed data through it is much higher. BGAN has different internet speeds depending on the kind of terminal used.
Latency or ping times over the BGAN network is between and milliseconds. Actual ping test was on a BGAN located in California pinging a California website that showed a milliseconds ping time in May, But there are some key differences, depending on how you need to use your terminal.
Some BGAN terminals have Wi-Fi, some are a bit faster, some are more rugged, some are better for broadcasting live news reports, and so on. Inmarsat allows several manufacturers to create BGAN terminals and the result is that the market is very competitive. Another helpful feature of BGAN terminals is excellent voice calling. Phone calls are only billed for the minutes used while making the call. Each terminal is assigned a unique telephone number.
Phones connected to a BGAN terminal act as any normal phone with dial-tone. Yes — for both audio and video calls. The limiting factor is the speed of the connection. BGAN terminals using standard BGAN service normally deliver speeds of to Kbps download by to Kbps upload, depending on the terminal and network congestion.
Faxing is quickly disappearing, and we recommend looking at using a paper digitizer located at the bottom of this page. Faxing is by default turned off, unless requested on activation, or during the service term.
Making or receiving faxes is just as easy as making calls. The great thing about aiming any BGAN terminal is that they have a very wide view angles, which means they start to see a BGAN satellite 40 to 70 degrees before they are aiming directly at it.
The audible and visual pointing indicators make pointing a breeze since satellites are easily found within this wide view angle. Simply aim the BGAN to attain the highest signal strength and press the registration button which is different for each terminal or use the web interface of the terminal.
Pointing normally takes about one minute with practice. The Hughes , , and , and the Explorer , , and will allow up to 11 concurrent users via wireless. You may connect a wireless router to non-wireless BGAN systems to make it wireless, although most wireless routers do require external power to operate.
The SIM card is a small plastic chip that activates the terminal.
