A LOOK AT THE FUTURE PHREAKING WORLD 


Cellular telephones — I low They Work 


by Eruee Alston 

This is a non -technics 5 explanation -of (he newest in mobile 
telephone communications, die cellular telephone, For some 
background let's review the mobile telephone as we knew it 
prior lo hut 1983 when cellular systems began operating id 
Chicago and Washington/ Baltimore. Improved Mobile 
t elephone Service ( 1 M I'S) si lows cal Is to he made from a car to 
a land telephone Or vice-verm, Car -to -car service is also 
a va i lahlc- Based tut radio era OS ['a issin n charaetcrisi its, a ny eiiy 
Or town Kin have a maximum of 12 radio channels in the 
150 Mhz hand for mobik telephone service. The transmitter 
power for die base sia lion (telephone com party) can. go as high 
as 2KX) watts Effective Radiated Power (ERE). T his may cover 
an area of '."Lit lo 15 miles. depending up rut terrain. The mobile 
radio is Limited to 1 5. 25. possibly 50 watts £RP, keeping in 
mind the power consumption from the an tom obi le battery. I o 
receive the sig.iifi I fro 1 V 1 1 he mobile rad io Hie telcpho nc compa ay 
encircles lhe transmitter wilh receivers, so wlwrever the mobile 
unit might he, it tain be heard, as it also must hear Ihe base 
Station transmitter. With IM'I'S in New York City, Los 
Angeles, or Madison, Wisconsin, Or any eiiy, Only 1 2 mobile 
telephone conversations can work at one time, assuming Lhe 
FCC aJJotii Led 1 hey; cil ies a 13 1 2 elui nuflls, 

Ehc FCC has allocated btiti channels in the 800 M bz band for 
cellular tclephnne seivice. The maximum pnwer for the base 
sttilioh is 100 watts FRP. for sl>c mobile radio V watts FREC 
(ThaL is not a misprint 7 waits') Based on transmission 
characteristics, a cellular radio system can have up Lo 333 
channels in a given geographic area . Each a rca can have two 
cellular systems, each with its own 333 channels in 11 given 
geographic area . Each a rea can have two cellular systems, each 
with its own 333 channels for the lotuJ ($6. Pivlure due 3 MTS 
system with its receivers encircling one powerful transmitter. 
Change the receivers to combined transmitter; receiver/ control 
equipment located throughout the geographic urea. These are 
called cell sires. Where Lhe une puwerful transmitter base 
station was located, cellular has an M l SO — Mobile T elephone 
Switching Office, llrat clrariiKls telephone calls from the land 
lines to the cell site nearest the mobile radio. The MTSO can 
also switch mobilc-to-mobilc calls, As the mobile unit travels 
from one cell site toward another, where a more powerful signal 
etui be transmitted between mobile radio and cell site, the 
MTSG switches the connection to die besl cell site, 1 1 now looks 
us if a maximum of 333 calls could go on in any one oelLuJu: 
system at any given time. This is not so. Based on topography 
and radio interference patterns, else same radio channel might 
be used in two or more cell sites in the slime system. These cell 
sites arc probably 1 lj to 1 5 miles apart, unlessa mountain or hi II 
is in ihe way. Iri tire United Suites, various manufactuntiis arc 
claiming that a properly engineered eciluiar system can handle 
up to 75 ,000 eihs ala given time. (The telephone term. is 75,000 
E3HCA — Busy Hour Call Attempts). Mo system has been 
installed that approaches this ligurc. Notice, though, that tins 
beats the 1 2 BH C A of 1 MTS with a lrcavy stick if cellular is only 
Capable of baLf Lis proposed capacity. 

Let's suppose your cellular telephone (it can be in a car, on a 
boat, t>rca tried with you) has llte number (5 1 fo 555-2fi(XI, I’m in

goes through the regular telephone system. It will end upal lhe 
{5 1 6} 555 FVi J’SD where it is serU to &U the (5 16) 5 55 cell sites and 
transmit ted. If your mobile telephone is turned on it will 
recognise the call, inform the M'J SO that it is in service, and the 
Ml SO will assign Us most powerful cell she a voice channel for 
the conversation, The MTSO will also trauMuil information to 
your rad io advising ot the channel number on which you wi 1 1 he

Yes, you ca n use your pi odem , , bu i cc Du Isu telephony is in its 
infancy! fcsullsmuy not always bouli Ltuil you hoped for. Right

With cellular systems, when you arc in Hie coverage area and 
your telephone is turned On. you will receive calls and you tan 
make oil Lis and expect to have the ability to talk until you are 
finished, The city of Sacramento, California lias 7 cell sites. 
Anywhere you drive in then Area you have cellular service, if

Ho w Cellular Phones 
Came About and 
What You Can Expect 

Cellular communications derives its. name from tae 
radiotelephone signal being t eVi nsm i i; 1 c< I by ;'i series of low- 
powensd [fi iorOwa ve antennas or cells. 

H istory 

Find proposed by EkilJ Laboratories’ creative thinkers an the 
Jute ] 9+bs, the udva need computer tech oology tn acrufi llv ism ke

The FCC, after li 13-year discussion, formulated its “tanal” 
rules on implementing the technology in IDflE, (Other 
oountnes, such ax Japan, Saudi Arabia, and Scaitd ijiflvia actod

experiments proved that the ccllulflr systcnii rid. i t>n-e*d 
perfectly and thul cellular com muni cat ions is a valuable 
service.

the country's 305 largest population centers; 10 date, lhe IfH)

historic breu kidp, and, a “non-wireline company One that is not 
associated with the phone company'. Two providers 0-1 service, 
a CCOi d i ng t o the FCC, wo n Id p re vent a monopo I i s t ic 
marketplace and foster competition. 

How a Cellular System Work* 

The TCC designated the S<Xl kill* band for cellular 
communications, Of lhe total '»> thirty-Khz-wide channels in 
Ihe band. 333 channeLs are reserved tor the wincliiK cellular 
company, .1.1.1 arc reserved for the non -wire line company, and 
Lhe Just 333 are held in reserve tor future cellular for other 
mobile) sc rv ice, 

When a celluLi r call is initiated . l! is received by the closest 
Jow-powpr microwave ante nna i n the cellu lar a i ca . From there, 
the call is routed completely Over the microwave system if it is 
going to another Cel lular phone, or if il is going to a land line 
(regular phone), the call Is then routed through a highly 
sophisticated computer switch and connected through to 
regular land Line phunes. As a vehicle moves throughout the 
oetlularareu (the geographic a rea in wh ich the ccllula r company 
OpC rates). I he signal is aulomatieuJly “handed off" from one cell 
to Che next, so chat the signal stays strong and clear, Just as an 
FM broadcast chonnot can be used in many cities across the 
country, a CelJu Lir channel can be used in different pa rts of the 
coverage area. This geographic sharing permits a cellular 
system to use radio channels mote efficiently than existing 
mobile panne systems , A number of phone Conversa Lions can 
lake place EhruughouL a cellu h,r area, at the same time, on the 
same channel without interfering wilh each Oilier. 

Cost 

Cellular hard wap; varies according LU lhe area of the 
country, and feu Lures of the model, (.ieueratly speaking., 
perhaps S99? to Si .800 or so for a vehicle-mounted unit, and 
S2.Q00 toiXCKHJ for portable and t ransptnlabk units, E .casing 
and rentals arc available in some areas. For lhe usage of the 
unit, the phone company charges a monthly fee, and a small 
charge per rail. 


things we're not Supposed to know about 

by S>r William 

Tn addition 10 the Captain Mid night episode, Lhere have been 
people recently throwing sin tic at LttJO’s satellite from iheir 
bae k ya i d d i ill C if l ra n sir. i L t e r s . W h L Lc t h c re "s n o re a 3 
imagination in ItaiL. it’s pretty impressive that all dishes can he 
made to work both ways. 

CapLain Mid night did more, thuugh. lEe sent □ signal with a 
message and actually bumped Ihe H BO signal off of their own 
satellite. What’s more, he apparently sent ii with lhe same 
se rumbling, technique used by TTlJO so that it would come out 
Oil lhe viewers' sets normally, Very impressive, 

A II of this has been leading up to Lhe more serious stuff: wta i 
is available for hunting someone Like Captain Midnight down. I 
know of radio transmission direction rlnrfeis thfli tan. find a 
source in less than 15 milliseconds. This. LOO. is impressive. 

I his equipment is only available to law enforcement agencies 
anti Lite -ike so you Or I can't get it (even if we could afford i i ), As 
i\ trui I ler of lad . we ca n’t even get a catalog from these people to 
see just what they make u ntess we happen to work for oaic 0 T 
"’those" agencies. 

“Why is that?" you may well ask. It's probably heeauxe they 
dotlK want you to know what else they make and se!L lu “law 
enforcement agencies’’. Not wanti ng 1 be general pu biic to know 
about things tike wallet tra US mil Lera makes sense. Any crook 
Iliac watches TV knows that an undercover cop might lie wired 
under his shirt li ke on TV. EJut how many would tin ok 1.0 check 
lhe guy’s wallet? 

ibis is all intcctsl ing. bul what gets me is all the equipment 
available for bugging people. Phone transmitters Ituit draw 
their power from 1 he line i I self a nd Lise the wires fo r its a menna . 
Guaranteed Lu look identical to the microphone part in a 
regular telephone. It only puts out two rtlilliwatls of power, hut 
they have Loads of rc-irAilsmittefs available to boost the signal- 

There are '"pffliilic" taps that work on the same principle 
but don ) iec]u ire access to the phone to be hi pped . just to the 
lines going to it. 

So just what a re “they” doing with these tli in ex? I f there V a 
good reason ro tap a phone, then a COut! Order is gotten and a 
recorder put on the line at the central office, all nice and legal 
So juSL what do “they” do with all nf this equipment that ss 
actually illegal to use?

Mountiin Beil announced in October that it laid detected 
massive fraudulent use of interstate long distance oiling 1 hat 
0 .i used (I isrujuio i) of telephone seivice in the Alamogordo (New 
Mexico) area. Area Manager Gene Whitehead said the 
sporadic disruption in scivicc had been caused hv the use of the 
Alamogordo switching facilities by people on the east Cbast 
calling Puerto Rico. 

He said the use of the switching, facilities had become so 
interne tliat local subscribers were having to make many 
nlLetnpLs to complete their Long d is LanCe calls. He noted that 
long distance calls into the area also were being blocked by the 
Cflst COOSI traffic that was being routed to F J ucrto Rico illegally 
through the Alamogordo swiLch, 

The use of remote switching offices, he said, such as the one 
in Alamogordo to comp I etc these lypes of Long d ista nee calls 
also causes disruption of Local service. For example, he 
explained, locnl telephone numbers are dialed as part of the 
lota! dialing sequence lo compile such cults And this causes, 
local telephones to ring. But when the telephones are answered . 
there as no one on the lane. 

He said thul 1 his pti rl i d. a lit r p rob] tail occurred i n Alamogordo 
two years ago, ant! has appeared in other areas of Lhe country. 
He said tlto perpetrators were using switching facilities, in 
Montana, but were blocked there. They Lhen lied into the 
Alamogordo exchange.

Computers Threaten Privacy 

TIk VoiN. 

A report by the Office ni Technology Assessor m wairns that 
advances in Government computer i/s’d record systems have 
eroded some of the individual protections established Ivy the 
Privacy Act nf IU74. 

According In the report, technological insprovftllWirLs iai

fraud, waste, and abuse, have assisted law-en force me r.1 
agencies and have streamlined sonic Gove raiment operations. 
But Lhe re port goes on to say 1 bat these advantages have been 
offset by new opportunue.s for unauthorized mxl dkgs! use of
