Whether military products, industrial products, or even civilian products, wireless technology has become an indispensable part of social development.
With the increasing demand of human beings for communication, the network has become an essential means of transmission. As the coverage required by the network increases, it seems that the wired network technology cannot fully meet people's needs. As a result, wireless networks came into being. The development of wireless technology is also in full swing.
From complex cabling to today, only a single wireless signal transmitter is required. From a PC-dependent machine, any device equipped with a wireless terminal adapter can now be used. The connection network presents unimpeded access at any time, in any location, on any device. status quo. The development of technology has also promoted social progress. Whether it is military products, industrial products, or even civilian products, wireless technology has become an indispensable part of social development.
Compared with wired networks, wireless networks are mobile, and there are no restrictions on communication cables. Communication terminals can be freely moved or arranged freely within the communication area. The networking is quick and flexible. Installation of a wireless communication system avoids cable trenches when installing a cable network. The cumbersome work of laying cables reduces the amount of construction; the coverage area is wide, wireless communication can be spread throughout the area where wired communication can be reached, and data communication can be realized where the wired network is not convenient; and the expansion capability is strong, and various topology structures can be formed. , it is very easy to expand the node.
In the industrial production, the main communication standards are WirelessHART, ISA100.11a and WIA-PA, and there have been many breakthroughs in the civil network. For example, Wi-Fi, which is a brand of wireless network communication technology, is held by the Wi-Fi Alliance to improve the interoperability between wireless network products based on the IEEE 802.11 standard. With this technology, terminals such as personal computers and handheld devices (such as PDAs and mobile phones) can be connected to each other wirelessly. Wi-Fi hotspots are created by installing an access point over an internet connection. This access point transmits wireless signals over short distances, typically covering 300 feet. When a Wi-Fi-enabled device encounters a hot spot, the device can be wirelessly connected to that network. Most of the hotspots are located in places accessible to the general public. The current hot spots are concentrated in airports, coffee shops, hotels, and campuses. With the popularity of the Internet and ease of setup, many homes and offices also have Wi-Fi networks.
In recent years, the development of handheld devices is changing with each passing day, and smart phones appear as if each user carries a computer, and these “computers†that cannot access wired networks require a portable wireless network adapter. Therefore, the MiFi device began to receive attention. MiFi is a portable broadband wireless device that is the size of a credit card. It is a combination of a modem, a router, and an access point. The internal modem can access a wireless signal and the internal router can share this connection between multiple users and wireless devices. MiFi is sometimes referred to as a personal "hotspot," which can simplify the setup of a small LAN. MiFi can support five users at the same time. Wi-Fi-enabled devices, including mobile phones, laptops, game consoles, and multimedia players, all have access to the Internet. MiFi devices can be used to set up a specific network and share the network connection anywhere through a cellular connection.
From wired to wireless, the development of network technology not only makes the use of industrial equipment more comfortable, but also enables people to experience the ease and speed of using the network. Of course, the development of wireless technology has also led to advances in technologies such as visual identification and remote monitoring. Today's network technology is leading the development of industry and promoting social progress.

Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
