 This task requires
-  * a ready BeagleBone Black equipped with the CC1200 operating at a symbol rate of 1.2 kBaude.
+  * a ready BeagleBone Black equipped with the CC1200.
-  * one TI Development Kit for the CC1200.
+  * 4C attached to a second BeagleBone Black equipped with the CC1200.
-  * Smart RF Studio sending packets with a symbol rate of 1.4 kBaude and a preamble count of 6 Bytes.
+  * 4C sending packets with a symbol rate of 1.2 kBaude and a preamble count of 6 Bytes.
 ===== Tasks  =====
   * the programming is done by extending the source files from the previous lesson [[network_protocol_programming_lab:channel_sensing|Exercise: Sensing a channel]].
   * Extend your program by a function that measures the RSSI within a frequency band. If no RSSI is detected, choose another band and try again. But, if an RSSI is detected, start receiving a packet. After packet reception, scan again ....
-  * Limit the number of frequencies to 3.
+  * Limit the number of frequencies to 3 (e.g. 850MHz, 820MHz and 950MHz). Die frequencies are chosen to be the lowest supported , the highest supported frequency and a frequency between them.
   * For testing, start your program.
-  * Use SmartRF Studio to transmit packets at the RF frequency of your supported frequency set.(do not forget to change the symbol rate and preamble count in SmartRF Studio).
+  * Use 4C to transmit packets at the RF frequency of your supported frequency set.(do not forget to change the symbol rate and preamble count in 4C).
   * Your program should recognize a valid RSSI and start receiving packets.
   * Now, change RF to a frequency to another frequency band. Stopping and restarting the transmitter ist not necessary.
