Cellular technology made for the application of macrocellular and limited traffic closeness. On that account this technology gives the adequate solution for the development of JARLOKAR (Local Network Access Radio) in area of suburban and also rural. But which important to remember the problem of limitation is quality of voice and frequency allocation.
There are some technology of cellular radio operating whereas this in the entire world. But nothing standard in the technology. These matters in the reality limit the system development of radio of itself cellular, especially which is concerning problem roaming.
Differ from the technology cordless, technological of cellular have the ability for the mobility of higher level and larger ones coverage. For example from cellular network shall be as follows:
• Analogue Cellular Radio
Among the system, system AMPS relative have the technological excellence, especially if evaluated from canal capacities conduct following accelerating its transmission. in this case mean that in system of AMPS of time of call development is shorter relative, something that it is of course very expected by operator STBS. Typical Network of AMPS.
In Indonesia this system have been made as STB National since year 1989, extending usage STBS in Indonesia, which is on its beginning apply the system NMT450 (STB-C).
• Cellular Radio
In growth STBS hereinafter, where make-up of efficiency of spectrum exploiting and quality of and also service type represent the very required matter, adjustment of technology digital cellular have come to the prima facie consideration.
Fundamental reasons from digital adjustment of technology in STBS for example:
a. Digital Signal relative more impenetrable compared to analogous signal
b. Peripheral tend to cheaper, along with its fast is digital technological growth
c. Make-Up of capacities, caused by economical digital modulation technique of spectrum
d. New Service type can be obtained, especially if integrated by ISDN
e. Better Security relative.
Big group of digital cellular radio system operating in the world for example NADC (North American Digital Cellular), GSM ( Global Sellular Mobile), DAMPS ( Digital AMPS), JDC (Japan Digital Cellular) and IS-95 (method access the CDMA).
In Indonesia systems which have been blazed the way its operation is GSM, this matter is relied on authentication of implementation GSM in Batam-Bintan as project STBSD.
• PCS/PCN ( Personal Communication System / personal Communication Network)
Technological this expands from society of communications wireless with the high mobility [is] which progressively expands its amount. PCS expand in United States while PCN in Europe. PCS / PCN can be interpreted as a new service form of telecommunications make a move the (Mobile Telecommunication) what more portable and pocketsize. What not owned by motion less radio telecommunications service (Fixed Radio Telecommunication). Technological this also enables integrated with the other communications network like to PSTN. If evaluated from its network hence recognizable PCS / PCN terrestrial and PCS / PCN satellite.
