Latency and data rate for gaming apps

Other Parts Discussed in Thread: CC2530

1. Is it possible to use RF4CE to transmit continuous data at about 100kbps (actual data not including over head) with low enough latency for gaming applications?

2. What is the max. data rate (actual data rate, excluding overhead) that is possible with RF4CE assuming I use CC2530.

3. What other issues will have to be addressed for achieving continuous low latency data transmission with RF4CE?

Thanks!

    Sudheer:

    Please see my comments to your questions

    Q1:

    Yes, this is possible to use RF4CE to transmit data above 100 Kbps EDR even with overhead. Latency will be in the range of 0 - 10ms. For gaming applications I believe you will need latency below 5 - 8ms.

    Q2:

    CC2530 is IEEE 802.15.4 radio as you know with a raw data rate of 250 kbps. You can call this the max data rate. If you are interested in some solid papers on the IEEE 802.15.4 data capacity. Please take a look at the following paper attached

    Q3.

    To maintain a solid high data rate througput it is important to coexist well with WiFi and other legacy 2.4GHz technologies in any given RF environment
