Significance

• Any wireless device that connects to the Internet is similar to GPRS. When you send or receive MMS, or browse the Internet on your cell phone, you do it through GPRS-like technology.
  
  

Types

• GPRS devices are divided into three categories: Class A, Class B and Class C. Class A and Class C are still under development, while only Class B devices are in use as of November 2009.
  
  

Class A and Class C

• Class A devices have GSM and GPRS modes active simultaneously, and can also transmit and receive voice and data as the same time. Class C devices can only have GSM or GPRS mode active at one time.
  
  

Class B

• Class B devices have GSM and GPRS modes active simultaneously but are unable to transmit and receive voice and data simultaneously.
  
  

Speed

• GPRS works on a shared bandwidth principle, offering a potential download speed of up to 56Kbps and an upload speed of up to 14.4 Kbps.
