An important aspect of radio communication is radio range, which is dependent on the location of the transmission and reception antennas, the transmission power, the condition of the local environment, and the frequency range.
The CC2564MODx module provides best-in-class RF performance with transmit power and receive sensitivity that provides twice the range and higher throughput than other Bluetooth-low-energy-only solutions.
Note The transmit power control and dynamic frequency management performed by RRM are not the TPC and DFS required for operation in the UNII-2 bands that are defined in 802.11h.
This product can be incorporated in wireless communication terminals such as smartphones, and supports communication methods which accompany fluctuations of the transmit power level.
From the information received from the WT 1300, the BS 1200 can then compute the received SNR as a function of the transmit power Q for the data traffic.
According to our calculation, the new antenna can lower the transmit power by up to 30% compared with conventional antennas and about 10% compared with conventional automatic tunable antennas.
Figure 8: Signal at -67 dBm When you check the signal coverage, make sure the AP's radio transmit power does not use a transmit power greater than what the client devices can support.
In addition, governments and military departments regulate the use of the electromagnetic spectrum(frequency and power of transmission) in various parts of the world, which leads to different standards and regulations governing RFID systems.
For example, by default, the Cisco Unified Wireless IP Phone 7925G uses the highest available transmit power by default 17 dBm/ 50 mW for 2.4 GHz and 16 dBm/ 40 mW for 5 GHz.
In free space there is only one transmission path, and the signal power at the receiver is given by Equation 7 as: where PR is the received power, PT is the transmitted power, GT is the transmitter antenna gain, GR is the receive antenna gain, and λ is the wavelength.
