Fixed & Mobile Satellite Internet Frequently
Asked Questions
StarBand® is two-way, always-on, high-speed Internet service via
satellite delivered to homes and offices virtually everywhere (including
the continental U.S., Hawaii, Alaska, Puerto Rico and the U.S. Virgin
Islands). Take a look at the G-27 satellite at the 129 degree orbital
slot (formally called IA-7 and before that T-7) Ku band footprint,
and the AMC-6 (72 degree orbital slot) Ku band footprint, the standard
.75 meter antenna will give you internet connectivity just about
anywhere within the 46 db line and even out to the 44 db line although
signal quality will be low and maintaining a solid connection may
be difficult near that line. A .98 meter antenna will take you out
to the 42 db line and a 1.2 meter will pretty much keep you connected
anywhere within the 40 db line.
You should take the foot print coverage maps with a grain of salt
since the map is meant to give you a general idea. It reads just
like a topo map especially where the lines are close together. At
these points the cliff effect comes into play and the signal will
drop off very rapidly.
As you approach the outer limits of your antennas performance in
a particular location you will notice that at night you will stay
connected fine but as soon as 10AM to about 6 PM roll around you
will lose receive lock because the satellites signal will not be
strong enough to over come the background solar noise.
The StarBand® Nova Sky Edge satellite modem is compatible with operating
systems supporting TCP/IP protocol such as Windows®, Macintosh®,
Unix® and Linux® (Call Center support limited to Windows 98, 98
SE, Me, 2000 Professional, XP and Macintosh OS 9, OS X).
A 2 way link to a satellite orbiting in outer-space requires a high
degree of accuracy. It is a greater challenge than pointing a TV
dish towards a satellite to receive a signal.
TV satellites transmitting their signal to the earth have a large
footprint. As long as you are in that footprint it is a relatively
easy task to aim towards the satellite and acquire that signal.
Transmitting a signal back is a much more precise task. Satellites
in geostationary orbit (like StarBand's satellites) are spaced approximately
45-50 miles apart.
If you draw a straight line between your dish and the satellite
it will be about 22,300 miles long, move your dish even one degree
off peak and the other end of your line has wandered off target
by approximately 389 miles.
There is the very real possibility that if your antenna is not
pointed correctly you would be causing interference to your satellite
or an adjacent satellite.
This is a very serious issue to satellite operators and is why
it is so critical that your dish is correctly pointed, locked down
tight and stabilized properly.
StarBand randomly monitors its earth stations and will shut down
your system if it detects any problems with your antenna alignment.
If this happens too often your system will be permanently turned
off and your certification will be revoked.
In the certification class you will learn how to adjust and check
your antenna alignment.
Getting certified to do a self-install can save you hundreds of dollars. If you are handy with tools, comfortable around computers, like following detailed user manuals and willing to invest some time taking a free online course you can get certified. It takes about 3-5 hours and involves several free tests. Please check our services page for detailed instructions on how to get certified
StarBand service is great for customers seeking up to 10 - 20 times
faster download speeds (depending on the service plan) than dial-up
can provide. We are not going to sugar coat this issue, all ISP
providers quote their speeds as “up to” and realistically you will
not always get those speeds, especially during peak periods of use.
Peak periods are around 7:30 to 10 AM EST and about 4:30 to 9:30
PM EST.
The Nova Sky Edge 1000 modem is advertised as “up to” 128Kbps up
and 1024Kbps down. Realistically during peak periods you will see
around 70 to 80 Kbps up and 600 to 800Kbps down.
The Nova Sky Edge 1500 modem is advertised as “up to” 256Kbps up
and 1512Kbps down. Realistically during peak periods you will see
around 150 to 180 Kbps up and 900 to 1100Kbps down.
During the late evening speeds will approach and sometimes even
exceed advertised speeds (both have VPN at dial-up speeds).
While StarBand can offer you a very high speed connection to the
internet there are some physical limitations to the service. Because
the signal has to travel an almost 90 thousand mile round trip from
your pc to the hub in Marietta, GA and back the ping rates (also
known as latency) are much higher than ordinary terrestrial services.
You can expect ping rates with an average of 800 - 900 milliseconds
and occasional ping times of up to 3000 milliseconds. This will
mostly affect action type games VOIP and VPN applications.
In general lower consumer class services are not great at supporting
VOIP over satellite on a consistent basis.
Depending on the VOIP appliance, it works at times but there is
often a delay, sometimes the conversation is garbled. In the past
we have discouraged customers from trying to get acceptable VOIP
servic over a consumer class Satellite service. However we have
finally found a service that is optimized to work with satellite.
By using a digital to analog box that is designed to work with VOIP
servers that are specifically configured to work over a satellite
connection we have been getting acceptable results. It is not like
making a call on a land based copper wire or cell but if you have
no other option it may be a good solution. Starband does not officially
support VOIP and if you use this new service we cannot promise that Starband
will not at some future point in time block the service.
Keep in mind that VOIP over satellite has virtually nothing to
do with the speed of the connection. It has a lot more to do with
consistent and predictable ping times (latency)and available bandwidth.
When ping times are all over the place and ranging from 600 Milliseconds
to as high as 3 seconds the connection is referred to as having
a lot of jitter. VoIP compression algorithms that try to compensate
for high ping times have a very difficult time dealing with highly
variable and unpredictable jitter in a consumer class VSAT connection.
This new Starband VOIP service seems to tolerate
it better than most VOIP services and it can run on as little as
8Kbps and still give fairly decent quality to the call.
Starband and HughesNet are a consumer class VSAT service. They are
not designed, to deliver consistent business quality VoIP services.
The above being said we do now have a low cost satellite
VOIP solution that works fairly well over Starband and
other consumer class Satellite internet services. Please check our
online store for more details on this product.
If you are a commercial customer or individual that must have carrier grade VoIP quality over satellite please keep in mind that the service must support:
a) Consistent latency. High latency isn't a problem. Users quickly
get used to the delay which really isn't all that much more than
when two cell phones communicate with each other. The problem
is consistent latency and in this, consumer class VSAT services
such as Starband do not hit the mark. Inconsistent latency is
responsible for noise, static, etc. Consumer class satellite services
often have latency that varies as much as 700ms to 3000ms. (That's
3 seconds).
b) Guaranteed bandwidth, referred to as CIR or Committed Information
Rate. When VoIP is initiated, satellite bandwidth has to be allocated
and guaranteed for the duration of the call. This is only going
to happen if there is a billing mechanism to make customers pay
for it. If bandwidth is not available, you get noise, distortions,
and disconnections. Starbands consumer class services do not offer
a way to provide CIR.
c) QoS or Quality of Service is required to prioritize VoIP traffic
over web traffic, email, peer to peer and all the other active
traffic. VoIP packets have to be delivered smoothly and evenly
and cannot be held up by other traffic.
d) SAR or Segmentation and Reassembly is indispensable for good
quality. VoIP packets are itty bitty small packets that have to
be delivered smoothly and evenly. If a small VoIP packet gets
stuck behind a large web download or file transfer packet, it
gets held up (creating jitter). SAR breaks the big packets into
little pieces, intersperses the small VoIP packets smoothly and
evenly between them, and then reassembles the big packet at the
other end of the connection.
Without these features, it is hard to get VoIP to work reliably and consistently over a consumer class
satellite service.
We do also sell commercial enterprise class satellite VOIP services that
will do a very good job of supporting VoIP, but as with most things
in life, you tend to get what you pay for, and you will pay more
for a VSAT system that supports good VoIP quality.
If you want consistent, quality, guaranteed VOIP service over a
satellite connection, be prepared to purchase a commercial grade
enterprise system with equipment pricing starting at around $1,599
and monthly fees of $299 to $399.99 minimum. Only those systems
come with guaranteed VOIP service level agreements (QOS), consistent
predictable ping times between 600 - 800 milliseconds and SAR.
Orbital Enterprises sells a Commercial Grade 1024Kbps X 512 Kbps
service that includes dedicated VOIP bandwidth and packet prioritization.
We use Gilat VSAT equipment exclusively for carrier grade VOIP over satellite because they are the leader
in VoIP over satellite with over 90% of the VoIP VSAT world market
share.
Rather than Use CIR like others do as a work around to VOIP Over
satellite Gilat modems have committed channels that we can program
to provide either random access or dedicated access. On a dedicated
channel you get VOIP prioritization and built in SAR. They don’t
take a slice of your existing bandwidth. In addition, the call terminates
at Spacenets soft-switch at their HUB and then goes out over the
Public Switched Telephone Network. No part of the call goes out
over the internet where they cannot control QoS and SAR. You are
provided with a USA Telephone # in the Area code of your choice.
Calls are as low as 5 cents per min if purchased in 1000 min bundles
or 12 cents per min a la cart.
Spacenets VoIP solution is also already 9-1-1 certified as per
US law. Your site is identified in the system and if you dial 911
it goes to a special call center that will instantly dispatch the
proper authorities. If your VSAT is mobile it is flagged in the
system as Mobile so the 911 call center can help you get help wherever
you are. Including dispatching the Coast Guard if you are on an
oil rig in the middle of the Gulf or the proper authorities if you
are in another country.

Yes you can but you will be required to get certified and will need
to purchase one of our mobility kits. We also highly recommend hands
on training but it is not required.
You will then be able to take your system on the road with you,
You can either take the antenna off your fixed home mount and bring
it with you or purchase an additional antenna and outdoor electronics
to travel with. Contact us for further details and pricing on extra
antennas and outdoor electronics.
Certification is required to do any install and pointing of the
antenna. Training is highly recommended for mobile systems. You
can complete the free certification and tests online at www.StarBand.com/training.
It takes 3-5 hours to complete the process. Detailed directions
can be found here.
Starbands consumer class service, like all other consumer class
satellite ISP services are a “best effort up to speed”. There is
no minimum assured speed or guaranteed service level.
Commercial/Enterprise grade satellite service plans come with guaranteed
service level agreements (SLA’s) and minimum assured speeds
Every ISP service places limitations on the amount of data that
you can move over your connection. Satellite ISP’s are especially
restrictive. Starband, HN and Wild Blue all handle this limitation
in different ways and when you are comparing services this is definitely
something you need to take a close look at. Here is how Starband
handles it:
To help ensure that all members have fair and equal use of the
benefits of the service and to protect the integrity of the service,
StarBand reserves the right, and will take necessary steps, to prevent
excessive consumption of bandwidth. By regulating this excessive
consumption, StarBand can improve upload and download speeds, congestion
and VSAT capacity for all of our customers. Please note that the
FAP thresholds are only monitored between the hours of 6:00am and
12:00am.

Customers who are close to exceeding their assigned bandwidth usage
for a rolling period of seven days will be sent a warning message
via a web message and via their StarBand email account. Customers
who exceed their assigned bandwidth usage for a rolling period of
seven days will again be notified via a web message and via their
StarBand email account. The web message will specify that the customers’
speeds will be temporarily reduced until the customers’ seven day
rolling average drops below the ‘exit limit’. The customer's normal
high-speed access (as specified in the customer’s contract) will
be restored after that time period. Because there is a seven-day
monitoring period, customers are not penalized for one-time or occasional
bandwidth bumps unless the total for the entire seven days is very
high. In addition, customers get one free pass to remove the restriction
by calling StarBand customer service and requesting a restriction
removal. Customers who repeatedly use excessive bandwidth and have
received multiple warnings may be suspended from using StarBand
services for a specified period of time.
