transmission rate is 1 Mbps. There are 40 channels with 2 M bandwidth, which is doubled from the classic Bluetooth 1 M bandwidth. According to Shannon's law, at a certain transmission rate, you can increase the channel bandwidth to reduce the signal-to-noise ratio, which is also one of the reasons for Bluetooth 4.0 low power consumption. If the unit is 1, the transmit power of 15.4 + ZigBee is 0.6, and that of Bluetooth 4.0 is 0.1. In addition, three

wireless router can also achieve wife wireless Internet access!!2. Several short-distance transmission of the internet of ThingsAt present, the use of a wide range of close wireless communication technology is wireless LAN 802.11 (Wi-Fi), ultra-wideband UWB (Ultra Wide Band), ZigBee, short-distance communication (NFC) and so on. Each of them has its own application characteristics, in terms of transmission speed, distance, power consumption and other

on servers. in this way, not only can the current activity be obtained in real time, but the devices in the home can be controlled through instructions, and the historical information and change tendency in any period of time can be investigated, provide suggestions and measures for correct and timely medical care. Previously, smart home networks were constructed using radio frequency (RF) technology, 802.11, and Bluetooth technology. however, none of these technologies fully meet the requireme

to information sent by public utilities. With smart energy and smart home systems, consumers will be more convenient and efficient, such as activating dishwashers when the electricity bill is low, or reminding users to add detergents in due time. Core features and capabilities of wireless network technology Wi-Fi is a communication technology based on the GHz band. It is good at fast transmission of large amounts of data between two nodes, but consumes high energy at the same time. In star conf

Panid Settings The sign of a ZigBee network is that Panid,panid is a 16-bit variable that can define 65,535 different networks of Panid numbers. We can use Panid to differentiate different ZigBee networks within the same channel. Panid is generally determined by coordinator, router and Enddevice access will be coordinator from Panid. You can also fix the Panid of router and enddevice to join a specific coo

almost all fields of Iot. Wireless Technology accelerates Smart Home At present, many manufacturers have begun to explore smart lighting in the lighting market. Many new office buildings, shopping malls, and airport projects have joined the wireless lighting system. For a commercial building, the energy consumption of the traditional lighting system accounts for more than half of the total energy consumption of the building. Now, the public advocates energy conservation and emission reduction t

Another is the traditional network, call

Just before a PDA with wifi features, so instead of using a PC to control the Smart car via ZigBee, it's more convenient to control it with a PDA, but since the. NET MF Development Board does not directly support WiFi, we have to control it indirectly, that is, PDA control pc, PC through ZigBee control intelligent car. For our developers, WiFi is the same as the normal cable interface, is the socket progra

Transport Layer: ensures data reliability and efficiency at the source and target nodes. ① 802.15.4/ZigBee protocol The IEEE 802.15.4 standard is dedicated to low-speed networks, and ZigBee is built on the IEEE 802.15.4 standard. The IEEE 802.15.4 protocol specifies the physical layer and MAC layer of the network; The ZigBee protocol specifies the n

In recent years, with the development of family-oriented control and automated short-distance wireless technology, opportunities brought about by smart home are becoming a reality. Compared with traditional Smart Home, light home has two obvious advantages: Easy installation and easy interaction. Among the various short-distance wireless communication technologies that have emerged, EnOcean, Zigbee, Z-Wave, and Bluetooth are currently the main means t

electrical appliances, set a temperature threshold, when the temperature reached this threshold when the start of air conditioning, such as the general summer indoor temperature of 25 degrees Celsius, if the temperature exceeds 25 degrees Celsius, then the air conditioning will automatically open. By periodically obtaining the current temperature in the room, and to compare the received information with the set value, when the temperature reaches the appropriate temperature, the automatic stop,
