Dear customers,
On this page, we would like to introduce you to the TIP network. (THE NEW BUSINESS NAME of
the EuroTel Classic network which you have had available to use since 1991).
The new name brings with itself completely new service programs--TIP60 and TIP TOP--and
two new telephones--NOKIA 540 and NOKIA 550. Read about the details on page 8 and 9.
History...
There was a time when having a telephone at home was far from the standard. Demand
exceeded the existing, considerably limited telephone network capacity by several times.
Many of us surely remember the waiting lists on the “end“ of which waited the
hoped-for telephone--the ability of communicating with the world, which was, is, and will
be a dream and today is even a necessity for each of us.
As business and the associated need to utilize telephones lines, computers, fax and
data transmissions developed, demand continued to increase. The first pagers (radio paging
pocket receivers) hit the market, making it possible to receive text and numerical
messages completely reliably and relatively inexpensively. The cost of the pagers was,
however, relatively high in addition to the fact that demand often outweighed the existing
capacity of the networks.
Due to the ban of public use, the development of radio telephones was slow here,
but the Czech mobile phone still emerged. It was called the AMR (automatic city radio
telephone) and was developed by Tesla Pardubice. It presented many disadvantages, but
still satisfied the many waiting applicants and is operated even today by SPT Telecom.
The main problem, which was the insufficiency of open frequencies, was first
resolved in conjunction with the use of a network whose development in the form of the
system bearing the name of NMT we associate with the year 1991. After this year, mobile
communication underwent massive development which with time is becoming more accessible
for a larger and larger portion of our population.
Today, the NMT 450 MHz system covers most of the territory in a number of countries
thanks to which it is continuously used by a great number of customers.
The TIP network is definitely not an “old lady“ who is out of touch as many
may think. But it’s not a completely analogue network either which would make
many people reject and categorize (of course, only to their own disservice) it among the
pioneers of mobile telephones. Unfortunately, even today many people, envision under the
term “TIP network mobile phone“ an enormous box which is almost unbearable to carry.
At the same time, if you pick up a mobile phone designed for the TIPO or GSM Global
networks, we dare say that you’ll be hard up to distinguish them from one another.
Differences, which are clear only to the eye of an expert, are blurred today by the rapid
tempo of development which is continuously moving forward.
The TIP network works in the 450 MHz band. Thanks to these low
values (compared to the GSM Global network), a better signal propagation is
becoming this system’s greatest advantage. Especially in the broken terrain of our
republic, the signal is capable of overcoming terrain changes without completely
interrupting the connection. For the most part, it is only weakened. Conversely, the GSM
Global network signal propagates only in straight lines. This means that changes in
terrain cause frequent connection interruptions. That clearly speaks on behalf of the TIP
network which provides its users with the best and more homogeneous signal coverage.
Presently, when the TIP network is essentially established (establishment began in early
1990), its signal covers 96% of the inhabited territory of our republic.
You can forget about news saying that it is a purely analogue network. The
only thing analogue about the TIP network is the voice transmission itself. Everything
else, including the exchange, is digital. This combination guarantees the next plus of the
TIP network--a smaller susceptibility to breakdown.
The services provided by this network and which can be provided only be a digital
exchange prove that it is truly a network which is not merely analogue! These are the
services: conference call, call waiting, call forwarding to a fixed line or mobile
telephone number or voice mail (the voice mail itself is only a digital exchange service),
fax and data service....
All connections made in the TIP network are carefully “controlled and
safeguarded“ by the management control center in Prague on Olšanská street.
EuroTel Prague has recently taken a number of steps and invested much money into
protecting the TIP network against its potential misuse. Slowly but surely it is thus
breaking down its customers´ unconscious confidence barriers toward the TIP network--the
impression that the mobile network is easy to abuse.
Few radios which can tune into 450 MHz have reception in this wave length. Thanks
to the fact that each call is transmitted by two channels (you speak through one and
listen through the other), this type of mobile phone can be considered as two radio
stations. Just like one radio cannot listen to two radio stations at once, it is not a
easy as some people assume to listen to a conversation held over a mobile phone. Each
radio transmits on the same frequency. The mobile phone, however, moves, and the receiving
and transmitting channels are continuously changing when the phone is “shifted from one
cell to another,“ from one base station to another. That’s why technically
eavesdropping is not simple. A person trying to eavesdrop on your calls would have to be
“in your reach“ at all times while you’re making the call which interests him. The
only thing that is technically possible is to program a telephone number into the phone.
Thanks to many measures undertaken by EuroTel Praha, anyone capable of this still cannot
program other algorithms which protect this specific telephone with this specific number
from being abused. That means that connection cannot be made sending or receiving a call.
As is obvious, the routine ability to eavesdrop on calls in the TIP network
is wrongfully attributed to this network. It is highly probably that people
unconsciously mistake this network with the Automatic City Radio Telephone (AMR) which is
still operated by SPT Telecom. Thanks to 160 MHz radio waves on which it transmits and the
high 30W output (pocket TIP network mobile phones have an output of .15W-1.5W), the AMR is
more simply intercepted.
The fact remains that whoever has the money, and has a lot of it (these are
astronomical costs), can use them for his own benefit and overhear calls. However, no
telephone network is safe from these kind of “pirates.“ Whether it’s a telephone
that we almost all have at home today or a digital or analogue network telephone. That’s
why one should never pass on important information (e.g. PIN) or to take care of essential
and strictly private matters over the telephone.
Compared to the past, the purchasing costs of TIP network telephones are comparable
to the costs of GSM Global network telephones. In addition, thanks to favorably low
tariffs and less expensive service program rates offered by this network, you can make
back your purchase costs many fold within a short period. If you plan to call a lot (the
more you call the cheaper it is for you), you don’t need some of the special services
which are currently offered by the GSM Global network alone (e.g. receipt and transmission
of SMS messages) and you won’t lack the ability to roam (you can use telephones for
international calls only in the Czech and Slovak Republics), then one of the
newest TIP network telephones--e.g. Nokia 540 or Nokia 550--will become an excellent
companion for your family budget. For companies equipped until now with GSM
Global network telephones, the newly offered telephones with low tariffs may become an
alternative solution to the financial budget.
