Bu teorik veri iletim h\u0131z\u0131\u00a0 bug\u00fcn kulland\u0131\u011f\u0131m\u0131z telefon \u015febekesinden \u00fc\u00e7 kat ve mevcut GSM \u015febekesindeki Devre Anahtarlamal\u0131 veri iletim h\u0131z\u0131ndan on kat daha fazlad\u0131r. GPRS devre anahtarlamal\u0131 veri iletimi ve k\u0131sa mesaj servisi ile k\u0131yasland\u0131\u011f\u0131nda en az maliyetli veri iletim hizmetidir.<\/p>\n
S\u00fcreklilik<\/p>\n
GPRS in sa\u011flad\u0131\u011f\u0131 en \u00f6nemli \u00f6zellik s\u00fcrekli \u015febekeye ba\u011fl\u0131 olmak,\u00a0 yani\u00a0 s\u00fcrekli\u00a0\u00a0 hatta (online) olmakt\u0131r. S\u00fcreklilik devre anahtarlamal\u0131 veri iletimi ile k\u0131yasland\u0131\u011f\u0131nda GPRS in en b\u00fcy\u00fck avantajlar\u0131ndan biridir.<\/p>\n
Yeni Uygulamalar<\/p>\n
GPRS,\u00a0 mevcut GSM \u015febekesi \u00fczerinden,\u00a0 devre anahtarlamal\u0131 veri h\u0131z\u0131ndaki (9.6 kbps) ve K\u0131sa Mesaj Servisindeki mesaj uzunlu\u011fu (160 Karakter) gibi k\u0131s\u0131tlamalardan \u00f6t\u00fcr\u00fc daha \u00f6nce m\u00fcmk\u00fcn olmayan pek \u00e7ok yeni uygulamaya olanak sa\u011flayacakt\u0131r.

Paket Anahtarlama<\/p>\n
GPRS sisteminde bilgi, iletilmeden \u00f6nce paket olarak tabir edilen\u00a0 birbirinden ayr\u0131, fakat birbiri ile ilgili par\u00e7alara b\u00f6l\u00fcn\u00fcr. Al\u0131c\u0131 taraf\u0131nda ise bu par\u00e7alar tekrar birle\u015ftirilir. \u0130nternet, paket veri\u00a0 iletiminin kullan\u0131ld\u0131\u011f\u0131 bir \u015febeke \u00f6rne\u011fidir.<\/p>\n
GPRS mevcut devre anahtarlamal\u0131 GSM \u015febekesi \u00fczerinden paket tabanl\u0131 hava aray\u00fcz\u00fc gerektiren bir sistem esas\u0131na dayan\u0131r. Bu kullan\u0131c\u0131ya paket tabanl\u0131 veri hizmeti opsiyonu sunar.<\/p>\n
Asl\u0131nda devre anahtarlamal\u0131 \u015febeke mimarisi\u00a0 \u00fczerine paket anahtarlamal\u0131 \u015febeke mimarisini eklemek olduk\u00e7a kapsaml\u0131 bir de\u011fi\u015fiklik gerektirmesine ra\u011fmen; daha sonra detayl\u0131 olarak incelenece\u011fi gibi GPRS,\u00a0 mevcut GSM \u015febeke yap\u0131s\u0131na bir \u00e7ift yeni altyap\u0131 bile\u015feni eklentisi ve baz\u0131 mevcut \u015febeke elemanlar\u0131 \u00fczerinde birtak\u0131m yaz\u0131l\u0131m g\u00fcncellemeleri ile paket anahtarlamal\u0131 ve devre anahtarlamal\u0131 \u015febekeleri zahmetsizce birle\u015ftirmi\u015ftir.<\/p>\n
Spektrum Verimlili\u011fi<\/p>\n
GPRS sistemi, hava aray\u00fcz\u00fcn\u00fc yani kullan\u0131labilecek radyo kanallar\u0131n\u0131, belli bir s\u00fcre kullan\u0131c\u0131ya tahsis etmek yerine\u00a0 kullan\u0131c\u0131 sadece veri g\u00f6nderirken veya al\u0131rken me\u015fgul eder veya kullan\u0131r. B\u00f6ylece mevcut kanallar di\u011fer kullan\u0131c\u0131lar taraf\u0131ndan da kullan\u0131labilir. Bu sayede s\u0131n\u0131rl\u0131 olan bant geni\u015fli\u011fi ve radyo kanallar\u0131 daha \u00e7ok kullan\u0131c\u0131 kullan\u0131r, ayn\u0131 \u015fekilde tek bir h\u00fccre daha fazla say\u0131da kullan\u0131c\u0131ya hizmet verebilir. Asl\u0131nda tek bir h\u00fccrede ka\u00e7 aboneye GPRS hizmeti sunulaca\u011f\u0131 kullan\u0131lan uygulaman\u0131n \u00e7e\u015fidine veya iletilecek verinin miktar\u0131na g\u00f6re de\u011fi\u015fir. Dolay\u0131s\u0131yla sadece \u00e7ok yo\u011fun zamanlarda kullan\u0131lmak \u00fczere tahsis edilecek kapasiteye daha az ihtiya\u00e7 olur.
