An industry with which the cost of data storage is being reduced and in which a wireless standardization is being carried out, hence in addition to the famous WiFi or Bluetooth, other terms such as Zigbee or Z-Wave have begun to be heard, between others.Now, what exactly are these wireless technologies and what are the main advantages or disadvantages between them.If you are thinking of buying a connected product such as smart light bulbs, for example, then surely you have already heard about these technologies.
![]() ![]() Next, we will show what each of them consists of and what are the main differences, advantages or disadvantages between them. Contents Features and differences between Bluetooth, WiFi, Zigbee and Z-Wave Bluetooth WIFI Zigbee Z-Wave Features and differences between Bluetooth, WiFi, Zigbee and Z-Wave Bluetooth Bluetooth is born from the hand of Ericsson and a group of companies in the technology sector that were later joined by other companies such as Microsoft itself with the aim of finishing. The joint work of all of them made this technology quickly accepted by manufacturers. Thanks to this wireless technology it is possible to connect several devices and exchange information between them in a comfortable and simple way. So much so, that we have been using Bluetooth for a long time to transfer content between devices or to connect from them to some systems such as hands free. ![]() But that is not all, since in addition, this latest version of the standard offers a power consumption of up to 2.5 times less than the previous version, which guarantees a lower battery consumption of the devices. Among the main features of this technology, we find: It operates in the free ISM band between 2,402 and 2,480GHz, so it does not require a license. Its range depends on the emission power available to the transmitting equipment and whether we are indoors or outdoors. It is oriented to the point-to-point connection or mesh network of few nodes. Its use is mainly focused on desktop computers, laptops, mobile or audio output devices, hands-free, sports or home automation devices and even toys, medical technology or industry. WIFI WiFi comes from Wireless Fidelity or what comes to be the same, Wireless Fidelity. It is a wireless data transmission technology used for Internet based on radio waves, such as the radio itself, television or mobile telephony. However, the frequencies used are different, specifically the WiFi uses 2.4GHz and 5GHz. The latest WiFi connectivity standard that we will begin to find from now on more and more devices is WiFi 6, formerly known as WiFi 802.11ax. However, recently the WiFi Alliance has renamed the numbering of the versions becoming WiFi 6, WiFi 5 and WiFi 4 which would be previously the standard 802.11ax, 802.11ac and 802.11n respectively. A new standard that basically comes to offer greater speed, better performance, greater capacity to have many devices connected and better energy efficiency. In the ten years that separate WiFi 4 from WiFi 6, we can say that the maximum transfer speed has increased from 600 Mbit s offered by WiFi 802.11n in 2009 to 9608Mbit s of WiFi 6, through a speed Maximum of 6933 Mbit s of WiFi 5 or 802.11ac. As far as uses are concerned, WiFi technology offers us access to the Internet from different devices when connecting to a particular network, while linking different devices to each other wirelessly. The range of WiFi networks depends on several factors such as frequency band, radio power output, receiver sensitivity, gain and antenna type, etc. In addition, remember that it is also possible to extend its reach with the use of directional antennas or repeaters. Among the main features of WiFi, we must highlight: It operates in the 2.4 GHz and 5GHz frequency band Its range depends on many factors but is much greater than Bluetooth. It allows the Internet connection of different devices and can also be used to connect devices to each other within a network. Maximum data transmission rate 9.6Gbps for WiFi 6. Difficulty crossing certain obstacles and may find interference with other waves emitting at the same frequencies.
