TWR-WIFI-AR4100

RF evaluation and development kits, boards are used to evaluate and develop wireless network designs that require a higher level of signal and radio frequency (RF) performance than traditional communication networks. The TWR-WIFI-AR4100 evaluation kit is one such development tool available on the market today. It is a tiny complete system that combines a radio frequency (RF) modern and an 802.11n Wi-Fi transceiver. These two components are then integrated onto a half-width-length board. The goal of this system is to provide the ability to evaluate power amplified RF designs using WLAN and MIMO antenna technologies, all based on a concept called Multi-Tier Multi-Channel (MTM) Wi-Fi.

The TWR-WIFI-AR4100 kit is designed to be a cost-effective, low-power solution for system designers. The board features the latest ARM Cortex-M4 controller, two on-board 802.11n Wi-Fi antennas, and an RF Transceiver modules for both 2.4 and 5 GHz frequencies. This makes the TWR-WIFI-AR4100 ideal for use in applications such as smart home base stations, wireless hotspots, wireless video surveillance cameras, and even test systems used to evaluate their own Wi-Fi performance.

The board also has several on-board antennas, both driven and passive, to achieve optimal performance. The passive antennas are low-profile ceramic tile type RF antennas with built-in gain to maximize the sensitivity and range of the receiver. The board also includes two onboard attenuator switches, allowing the designer to adjust the path loss according to the application requirements. Additionally, there are two antenna ports for connecting external antennas.

The main goal of the TWR-WIFI-AR4100 is to help system and design engineers measure, validate, and optimize their applications using advanced RF design techniques. To facilitate this goal, the kit includes the Microchip Digital Signal Processor (DSP) for transmitting and receiving up to 4 channels and with up to 4×4 MIMO (Multiple-Input-Multiple-Output) RF technology. With this technology, engineers are able to evaluate the impact of antenna placement on the range and throughput of the system, as well as the effect of a given network environment.

The onboard DSP also helps in the measurement of the system gain, noise figure, and signal-to-noise ration, thus giving valuable data for system optimization. The TWR-WIFI-AR4100 also includes the Microchip Wireless Instrument Manager, which provides an intuitive graphical user interface on top of which the test and evaluation jobs can be quickly and easily created and monitored.

Overall, the TWR-WIFI-AR4100 provides an all-in-one solution for evaluating and optimizing wireless designs. With its on-board DSP, test and evaluation functions, and multiple antenna connections, the TWR-WIFI-AR4100 helps engineers to evaluate, validate, and optimize a given system in order to achieve maximum performance.
