Mobile Phone Signal Boosters, Frequently Asked
Questions
How will my Mobile Phone Signal Booster equipment be delivered? If an order is received before 12.00pm on a Working Day we will aim to despatch these the same day for Next Day Delivery. Orders after this cut off point cannot be guaranteed for same day despatch. Larger orders will be sent via InterlinkExpress and Delivered before 3.00pm, smaller orders will be sent via Royal Mail. Please note ALL orders will require a signature.
Why can I get a signal on my mobile phone outside and not inside the
house?
Houses built within the last four years have insulation panels backed
with foil on the outside walls. The foil acts as a total barrier for mobile
phone signals.
How do mobile signal boosters work?
By placing an aerial outside the building which is connected to an
internal device, the mobile signal is in effect relayed thus regaining
connectivity.
What is the least that I can pay and get a result?
This depends on the strength of the signal outside but given that it is
good, then given that one's phone needs to be on a tether, the price can be as
low as £29.50. This is made up of a small blade antennae and a coupler that is
attached to the back of your phone via a Velcro pad.
What constraints or consequences for going the cheapest route?
All three solutions at the cheap end need a cable running from the
external antennae to your mobile phone. To put it another way, these systems
can only serve one phone at a time. Often useful for those on the move or for
people living on their own.
Is there a solution offered when I can't even get a signal on my mobile
phone outside the building?
Yes, one uses a highly directional antennae called a Yagi Aerial and
this is very focused and will receive a signal from the appropriate mast many
miles away if properly orientated
What is the difference between the various types of antennae?
(Aerials)
The Yagi Antennae is the most focused but in areas of good connectivity
a simple stick antennae or panel will do a perfectly satisfactory job.
Are there any things (Golden Rules) that I must be aware of?
Don't ever have the internal panels or domes pointing back at the
external antennae as this could cause a thing called' Howl Around' which will
not only render your own system useless but could affect other users in your
area as well
Supposing I am the only person using a mobile in the building, then is
there a route that will give me a truly cost effective solution?
Use one of the tethered booster kits. The first two the TB01 and the TB02
are relatively transportable whilst the TB03 using the highly directional Yagi
Antennae and once orientated, stay in place. You only need this last solution
if the signal outside is not very good or even absent.
Why does MobDev offer various kits within each product range that look
identical?
This is because different mobile signal providers operate on two main
frequencies, GSM900 and GSM1800. Thus Vodaphone and O2 are on GSM900 and the
rest apart from 3G phones but including thelikes of T-Mobile, Orange and
Carphone warehouse use the GSM1800 frequency. We do one of the TX series which
operates on GSM2100 and that is to enable 3G phones. Although the kits within a
given range look very similar, they serve different frequencies and this is why
we need toknow who your providors are.
What is the significance of various mobile phone signal providers?
They operate on different frequencies.
Can 3G phones be enabled?
Yes. The tethered kits are multi frequency and these will do the job.
For a more sophisticated solution, then the TX kit designed for GSM2100 is the
solution.
Would I need to use the services of an electrician or could I do the
installation myself?
The tethered kits and the TX series are within the capabilities of most
people but if in doubt, then use a friendly electrician. Better safe than
sorry. The TG and the SB series must be installed by qualified
electricians.
Is the orientation or positioning of any of the components especially
important?
Some of the Antennae, particularly the Yagi, need accurate positioning
so as to achieve satisfactory signal strength. Apart from this, never allow and
aeril being used indoors to point back at the external antennae.
Which kits are possible for the ‘do it yourself individual' to cope
with?
The booster kits are usually within the capabilities of the ‘do it
yourself' sort of person as are the the TX kits but if a Yagi antennae is used,
it is advisable to use an aerial specialist so as to ensure perfect
orientation.
Will this telephonic enablement kit interfere with any other equipment
such as television satellite and audio set ups?
No
Given that one has been warned not to stand too close to transmission
masts, does any of the units sold by MobDev risk radiation damage? Microwave
radiation? Quantify.
No more than the risk when using a mobile phone out doors. The media has
suggested that spending hours every day with a mobile glued to one's ear might
be damaging but I think that the jury is still out on that one. Apart from
this, the signal transmitted within the building is no more than you would
expect in any area of good mobile phone reception.
Do these units consume much power? Quantify.
Under five watts.
Is it possible that these kits could cause power surges?
Given their miniscule power consumption then the answer is a definite
no.
Is there a tech support helpline?
Until further notice the help line is 01935 891046 but it is better to
email
This e-mail address is being protected from spam bots, you need JavaScript enabled to view it
What is the difference between various providers that will affect my
choice of equipment?
Different providers may use one of three different frequency and the kit
that you purchase must deal with the correct frequency for your chosen
provider.
Will the installation look intrusive when installed in my house?
This depends on how the installation is done but given professional
installation then it can be hard to see anything at all.
Are there any other companies offering the same sort of products?
Although there are a few other companies doing similar products, none of
them are as neat or as effective as the range sold by MobDev. We have trawled
the whole World to ensure that we market the best devices for the purpose that
are currently available
Can one move any of MobDev's enablement kits around when
traveling?
With the exception of the first two tethered kits then the answer is no.
If the position of the nearest suitable mast is not known what are the
various means of locating the aforementioned mast?
Details of local masts can be found on www.sitefinder.ofcom.org.uk but if even that
fails. Then the TX series which have three lights on the front can be used. Couple a highly directional aerial like the Yagi to the TX unit and slowly move the aerial around through 360 degrees. For most of this time the lights on the front of the TX unit will consist of one green light and one or two red lights. When the green light shines on it's own, then the directional antennae is pointing at the desired signal mast.
If I move house can the kit then be transferred or transposed? It depends how determined you are but the first two kits which are aimed at the single user wouldn't pose many problems. As soon as a highly directional aerial on a mast is used not to mention hard wiring of the relay unit inside the building, then you may as well sell the system to the new purchaser or tenant and start again when you move into your new house. Are there any legal issues with the use of mobile phone signal boosters?
There are laws that govern the use of these products in various countries. We suggest referring to the governmental organization having jurisdiction in your particular area, as this varies from country to country. All our repeater products including the TX, TG & SB range are CE approved. We would encourage users to contact your specific Mobile provider to obtain permission. Please note this does not apply to the TB01, TB02 & TB03.
