Can I use a WLAN or Bluetooth antenna together with the Nordic 2.4 GHz nRF devices? The system returned: (22) Invalid argument The remote host or network may be down. Do you have a printed 868/915MHz loop antenna layout available for the nRF905/nRF9E5 device? It has been shown that for an input signal x(t) = A(t)ejΦ(t) , the output y(t) of the PA can be written as (for A ¾ xsat ) y(t) = f[A(t)]ejΦ(t) http://www.eetimes.com/document.asp?doc_id=1277804

Packet Error Rate Formula

Since 802.11b affords only three frequency channels, one of the three cells (for example, Cell III) experiences ACI from the other two cells. Should we connect the die attach pad on the QFN package? I am not able to debug or program my nRF device from Keil, what might be the problem? Do I need to tune the antenna in my design to acheive 50 Ohm impedance?

The linearity of the PA is a key parameter as it is closely related to power consumption and to distortion, hence BER. How can I match this antenna to the nRF device antenna port? DucaG. Bit Error Rate Example How should I connect the quarter wavelength printed monopole antenna, documented in your white paper, to the nRF device?

are used to observe the effect of TX-RX distance. –satish Sep 25 '12 at 16:04 mmm I'm not totally agree with you. These results were derived from a simulation setup implemented in MATLAB that assesses the BER performance of a complete WLAN-OFDM link. Depending on the scenario, there are lots of IEEE papers, ex: BER simulation for WLAN networks in realistic environment share|improve this answer answered Sep 25 '12 at 11:18 satish 662 https://www.nordicsemi.com/kor/Nordic-FAQ/Silicon-Products/nRF24L01/How-to-measure-Bit-Packet-Error-Rate-BER-PER-on-the-nRF24L01 D.J.G.

In comparison, a similar 802.11b configuration (Figure 5) leads to a co-channel at 2R, a co-channel at root 7R, two adjacent channels at 2R, two adjacent channels at R and one Bit Error Rate Calculation The signal-to-interference noise ratio is therefore equal to SINR = (2f)-1, which is 31.39 dB. Revision 2.0 of the nRF24L01 Product Specification include some previous undocumented features. Should we connect the die attach pad on the QFN package?

Once we have bits in error it has been divided by total number of bits to obtain BER (Bit Error rate). When I use the Keil license included in the Development Kit to get a License ID Code from Keil, it says: "Expired: Mar 2008." What should I do? How should I connect the quarter wavelength printed monopole antenna, documented in your white paper, to the nRF device?

Figure 8 shows the data plot. Eine zusätzliche Reed-Solomon-Kodierung reduziert das minimal benötigte Eb/N0 auf weniger als 3dB. It should be done over at least 10000 bits (256bits in each packet, means >40packets) to get a good indication of the BER. navigate here In general, interference is either caused by radio devices operating in the same bands or by thermal noise, or both.
