National Instruments WAP-3701 Wireless Transmitter

The WAP-3701 from National Instruments is an industrial grade wireless transmitter that acts an access point, bridge, and client all in one. Designed for reliable wireless network connectivity even in harsh environments, the transmitter supports both IEEE 802.11b and 802.11g wireless standards and features dual redundant power inputs. The power input voltage of the device ranges from 12 to 45 VDC. The WAP-3701 is ready to be mounted on a DIN-Rail mount, further enhancing its suitability for both industrial and factory applications.

Some of the key features of the WAP-3701 include its compliance with 802.11g/b wireless standards and its support for security protocols such as WPA, IEEE 802.1X, and MAC address filtering. The transmitter provides secure data transmission with both 64-bit and 128-bit WEP encryption. In addition, it boasts advanced security measures including RADIUS authentication. The built-in web console of the device makes it easy to configure and manage the wireless settings, including RF channel selection, data rates, and transmission power adjustment.

This versatile wireless transmitter is optimized for high performance, with data rates of up to 54 Mbps using OFDM modulation. Several options are included for managing wireless connections, such as load balancing across multiple access points. The NI WAP-3701 supports both access point and bridge modes, offering diverse network functionality that serves as either a dynamic or static LAN-to-LAN bridge for seamless data exchange between wired and wireless networks.

Two swivel antennas (dBi RP-SMA type) can be used with the transmitter in order to enhance signal reception. With a focus on flexibility, reliability, and security, the NI WAP-3701 is an ideal wireless solution for industrial environments that require robust data security and network access. This ruggedized unit is housed in a robust IP30-rated metal casing and has an operating temperature range of 0 to 60°C (32 to 140°F). The storage temperature range is -20 to 70°C (-4 to 158°F), ensuring that the WAP-3701 can withstand even the most demanding industrial conditions. It has an ambient noncondensing relative humidity that ranges from 5 to 95%.
