Evaluated from its application, technology wireless can be categorized to become two that is: technology wireless for the service of remain to, recognized with the term WLL (Wireless Local Loop) or is also referred as by JARLOKAR (Local Network Access the Radio) and technological of wireless for the service activities of communications make a move, what is in character limited to be referred as by cordless and also which is not limited, so-called mobile communication.
Technological growth of wireless, concerning some aspect, that is aspect from mechanism access the, aspect coding, aspect of security and aspect of capacities development for the service of broad band and also its standard aspect.
• Analogue of Cordless telephones CT0
Phone the cordless of this type of still hence analogous technology. Frequency 49 MHz and use the method access the FDMA. Communications which can be conducted by still one way.
• Analogue of Cordless telephones CT1
Phone this analogous cordless operate on the network PSTN. At its consignor unit operate on the band 1,642-1,782 MHZ (20 KHZ spacing) and for the unit of portable use the band 47,456-47,543 MHZ (12, 5 KHZ spacing). Maximum of power handset is 10 MW and have the energy reach around 200 m.
• Cordless telephones CT2
Beside Indonesia, many state using this technology CT2. In Indonesia more knowledgeable with the title telepoint. Amount of mean market less than 20 % compared to by customer of cellular and PCN. Technological this use the bandwidth 4 MHz from 864-868 MHZ ably handle traffic until 40 carriers, by carrier is spacing of each 100 KHz.
This System is very compatible used at area urban, suburban and also difficult area reached by cable network. But with the situation in Indonesia enable the technology CT2 only just outgoing call to limit this technology alternatively.
• Personal Handyphone System (PHS)
Come from the consumer state is Japan. Technological this serve the purpose of fixed and also low mobility applications able to support the voice service, data and ISDN with the beet rate 32 Kbps ADPCM.
Some concept which on the market by PHS at application WLL to include; cover the Home Cordless telephony, Public Service, and also wireless PABX as well as direct mode (handy talkie), can be jointed by PSTN and approach link can use the radio and also cable. Frequency band used is 1895-1918, 1 MHZ.
• Digital European Cordless Telephone (DECT)
Technical Standard follows the ETSI (European Technical Standards Institute). Now have operated in 32 state. Its Coverage area around 300 m for the Pico cell. But for the condition of special can be developed again. DECT earn the application at some usage for example: household, public, business and local loop applications.
• CT3
CT3 represent the digital system property developed by Ericsson.
