Citizen Systems offers wireless LAN and Bluetooth communication printers under its “Wireless Printers” category. We also propose a selection of connection methods to suite the installation environment, including a method to connect to the access point by wired LAN for more stable communication.
For users who finds the wireless LAN environment unreliable and wish to avoid connection communication problems, we recommend the use of wired LAN connection via access point.
Compared to wireless LAN, Bluetooth is easy to set up and there are fewer problems concerning communication obstacles. Currently, there is an increase in the use of business equipment centering on mobile devices.
See the comparison below of the characteristics and specification between Bluetooth communication and wireless LAN.
|Bluetooth||Ver. 2.0 and above *1||2.4GHz|
|Wireless LAN||IEEE802.11b/g/n *2||2.4GHz|
*1 Citizen Systems has several product types depending on the model.
※*2 IEEE 802.11n includes a 5GHz specification
POINTIt is important to check the radio wave environment of the area in which the wireless LAN is to be installed
Wireless LAN does not require cable connection, making it convenient and easy to set up. However, frequency band congestion gets more severe every year.
Radio interference comes not only from smartphones, PCs, and other wireless LAN devices, but also from Bluetooth equipment as well as microwave ovens.
There is an increased risk of problems such as reduction of communication speed and breakdown of communication.
In some cases, this can even interfere with a user’s business.
Wireless LAN standards are as listed below and each standard generally consists of what is listed in the table below.
Citizen’s wireless LAN (Model No.: IF1-WF12) uses the 5.0GHz band and the 2.4GHz band of IEEE 802.11a/b/g/n.
|Standard||Frequency Band||Maximum Speed (Theoretical Value)|
