Q:

What is the maximum data rate supported by a GSM system?

Answer

- The maximum data rate supported by a GSM system is 9.6 kbps.
- However there are extensions to GSM standard to improve throughput.
- GPRS is one of the extended GSM service.
- The extended standards of GSM allows theoretical data rates on the order of 114 Kbit/s, but with throughput closer to 40Kbit/s in practice.

Q:

What gross data rate does GPRS provide?

Answer

- GPRS provide gross data rate of 22.80 KBPS / time slot
- Voice uses only 13KBPS/ time slot and the rest is consumed by Error Correction Code
- Error connection code is utilized for detecting and correcting the transmission errors
- As voice is compressed, the usage of Error connection code is mandatory

Q:

What is Wi-Fi technology and over which frequency band it operates?

Answer

Wi-Fi technology is a technology used for transmitting a signal using the 802.11 specifications works a lot like it does with a basic Ethernet hub: They’re both two-way forms of communication, and they both use the same frequency to both transmit and receive, often referred to a half-duplex. WLANs used radio frequencies (RFs) that are radiated into the air from an antenna that creates radio waves. These waves can be absorbed, refracted, or reflected by walls, water, and metal surfaces, resulting in low signal strength. So because of this vulnerability to surrounding environmental factors, it’s pretty apparent that wire-less will never offer us the same robustness as a wired network can, but that still doesn’t mean we’re not going to use or run the wireless or Wi-Fi.
