Yet another question about nRF24L01

Wireless & IoT
1

The 2.4GHz ISM band is now full of Hopping and Direct-Sequencing Spread-Spectrum devices, such as Bluetoth and Wi-Fi respectively. Does the old fashioned plain Gaussian-Frequency-Shift-Keying device, such as the nRF24L01, still have a chance? May be it has an advantage because no one else transmits all the power in a narrow 1 or 2 MHz frequency band any more?

Experiences? Observations? Theories? Opinions?

Given the channel switching time, one could theoretically implement a channel hopping algorithm. Keep in mind the Z1 has it, and they have some friendly white papers on how to do this.

The nRF’s are friendly. You don’t have to deal with the large cost and bulkiness of bluetooth.
