Bluetooth provides convenience and helps increase the productivity that devices have by taking cables and clutter out of the workspace. With the help of this technology, people can access smart devices over a short distance, have wireless communication while on the go, and do mobile printing with their smartphones or tablets.
Bluetooth allows data exchange between devices, like mobile phones, printers, and computers by using wavelength UHF radio frequency. Bluetooth strengthens the bottom line by eliminating cable-related costs while enabling device-to-device connections. With the help of this technology, people can execute everyday tasks hands-free. The vast majority of desktop computers, laptops, tablets, cell phones, printers, speakers, and smart home devices that are available in today's market support Bluetooth connectivity. Bluetooth has quickly gone from a funny-sounding, misunderstood emerging technology to one of the most-valued features demanded by enterprise mobile computer users today.
What is Bluetooth?
Bluetooth is a global standard for a small radio module to be plugged into computers, printers, mobile phones, etc. A Bluetooth radio is designed to replace cables by taking the information normally carried by the cable and transmitting it over radio frequency in the unlicensed 2.4 GHz frequencies to a receiver Bluetooth radio chip. This technology not only enhances the convenience and productivity of various devices by taking cables and clutter out of the workspace but also enhances the bottom line by eliminating cable-related costs. Bluetooth is a wireless technology that allows the data exchange between devices, like mobile phones and computers, using wavelength UHF radio frequency.
What is the Wavelength of Bluetooth Waves?
Bluetooth uses short-wavelength UHF radio waves that have a frequency of around 2,400,000,000 to 2,485,000,000Hz. This is the equivalent of 2.4 to 2.485GHz, which is the standard range that the Federal Communications Commission set for low-power general usage.
What is Bluetooth Used for?
Bluetooth has many applications for this technology both in everyday, personal activities as well as industrial and business applications. Bluetooth is a technology that utilizes a radio frequency to share data over a short distance, diminishing the need to rely on and use wires. Bluetooth is used for pairing devices such as printers and beacons to other fixed or other Bluetooth-enabled devices. With Bluetooth now paired between devices, data can be shared simultaneously.
Bluetooth enables wireless devices to share and transfer files. Mobile devices can now connect with Bluetooth speakers and play music from their phones to the connected speakers. Warehouse workers are able to scan a barcode with a scanner on one hand and quickly print out a label on the other.
How Does Bluetooth Work?
For Bluetooth to function correctly, devices must have Bluetooth enabled and must be within range of each other. Once both devices are in proximity, the devices to which a user wishes to connect must be paired. An automatic message will appear on both devices prompting a message asking if you would like to pair with another. This means that both devices trust the other to exchange data simultaneously. This exchange is secure via encryption. Once devices are paired, Bluetooth can now start to effectively work by using low-power radio wave technology on a frequency band of 2.4 GHz.
Is Bluetooth a Secure Connection?
How secure is Bluetooth? Bluetooth connections are wireless connections that are considered to be relatively secure. For security reasons, Bluetooth devices usually need to be paired before they can start transferring information and files. Connections are commonly encrypted, adding a layer of protection from other devices that may be nearby.
What is a Bluetooth Beacon?
A beacon is Bluetooth technology that is an active RFID Technology. Bluetooth Beacons give you the actionable insights you need to make your business more effective, competitive, and profitable. A Bluetooth beacon is usually a small, wireless device. It securely transmits a continuous radio signal that nearby smart devices can see. Beacons usually work by using Bluetooth Low Energy (BLE). BLE transmits fewer data over a smaller range. This is why it consumes less energy.
What is Bluetooth Low Energy Used For?
Low energy beacons transmit location data to mobile devices or dedicated gateways and forward them over Wi-Fi or mobile to a platform (middleware) that turns them into location data. Examples include situations where a system needs to be installed without disruption of business processes (i.e. healthcare), where you are using people’s existing equipment (cellphones, mobile computers) to crowdsource the location of your assets. Another case for Bluetooth low-energy beacons is to provide inexpensive, easily installed pay points that a retailer’s loyalty app, on consumers' smartphones, can use to drive customer engagement.
What is 802.11b?
802.11g is a form of Wi-Fi created for transferring information via wireless networks. It operates on a 2.4 GHz bandwidth and supports data transfer rates of up to 54 Mbps.
Can 802.11b/g and Bluetooth coexist in the same environment?
Bluetooth and 802.11b/g share the same spectral band (2.4 GHz). Therefore, cross-interference will be inevitable. A reduction in throughput can result. In general, Bluetooth devices are less susceptible to coexistence problems because of the following reasons:
Bluetooth is a frequency-hopping spread spectrum (FHSS) technology, which means if a channel is busy, Bluetooth will immediately hop to a different channel to transmit the packet of information. 802.11b/g uses direct sequence spread spectrum (DSSS) technology, which has a different method to transmit signals. Shorter packets—Bluetooth packets are typically a fraction of a millisecond long compared with a few milliseconds for 802.11b/g. This reduces their collision susceptibility. Bluetooth is less considerate. An 802.11b/g station first waits for silence and only then transmits. Bluetooth, on the other hand, is inconsiderate of surrounding transmissions—it simply “barges in” whenever it has something to transmit. In summary, these technologies can coexist. Several manufacturers have developed coexistent schemes. However, if the number of Bluetooth devices is very large around a wireless network (802.11b/g), most likely the throughput of the 802.11b/g devices will be affected. Zebra QL Plus and RW series mobile printers can include both Bluetooth and 802.11b/g radios, but can’t use the two radios simultaneously.
