NFC devices can communicate in either one of the two modes: active and passive mode. These modes determine how two NFC-enabled devices talk to each other. The distinction between modes depends on whether, a device generates its own RF field or used power from another device. In communication...
As an example, if a ceiling-mounted patch antenna is required to cover a certain area from a height of ~26ft (8m), the RF survey must determine the minimum Tx power required to achieve this intended coverage (this determines the minimum TPC value for the ...
The RF receiver uses all-electronic devices and InP-HEMT technology. A major advantage of such a photonics-based RF transmitter is that it makes the transmitter core (as shown in Fig. 12 [12]) very compact and lightweight; thus, it can be placed anywhere in the field. Furthermore, a ...
RF is created by applying alternating current (AC) to an antenna to produce an electromagnetic (EM) field. ■ Wireless networks use the EM field for communications, which is the region of space that is influenced by EM radiation. ■ On wireless networks, amplitude decreases with distance, resu...

Cisco Catalyst 9800 Series Wireless Controllers: The Catalyst controllers streamline the best of RF excellence with open, programmable Cisco IOS XE benefits, meaning you no longer have two operating systems to manage. These modular, reliable, and highly secure controllers are flexible enough to deploy...
Rf = 10K Ohms Using these values, the collector current is roughly 7.5 mA meaning that the voltage at the collector, assuming a 9V supply, would be 4.7 Volts (i.e. giving the output a large peak-to-peak swing before hitting saturation). Knowing that the hfeof the transistor at this cu...
Note: The RF group leader is chosen based on the controller with the greatest AP capacity (platform limit.) If multiple controllers have the same capacity, the leader is the one with the highest management IP address. ● Auto mode: In this mode, the members of an RF group elect an RF ...
In MIMO systems, the capacity is directly proportional to the number of antennas. Each antenna is connected to its own RF chain which leads to unnecessary dissipation of power in MIMO communication and incurs additional system costs. SM can be applied to alleviate this issue. By choosing differen...
