Bluetooth technology got its start in early 90′s by engineers at Ericsson in Sweden. Afterwards, a small grouping of technology vendors like Ericsson, IBM, Intel, Toshiba, and Nokia put together the Bluetooth Special Interest Group(SIG) in an effort to formalize the technology to make it an industry standard.

Bluetooth relies on a frequency-hopping spread spectrum radio technology to communicate wirelessly between a master gadget and as many as seven slave items. This means that your primary item, whether it be a smart phone, a mobile computer, or and apple ipod, can offer up to seven different Bluetooth devices linked to it concurrently. Although it could possibly appear that all devices are doing the job concurrently, the master device truly talks to each slave system in short sequence. It happens so swiftly you won’t ever observe, even when listening to songs on Bluetooth earbuds.

Bluetooth is simply a short-range wireless communication technology. Products receive an average range of about thirty ft. Naturally, the farther separate you are, the less condition the signal may have. It’s usually not really a huge matter because Bluetooth products are supposed to work in closeness to the master device. Some examples of this include a wireless mouse and keyboard for your computer, or wireless stereo speakers for your home music system.

Considering that Bluetooth technology also has such a restricted range, it utilizes hardly any electrical power. This is extremely important, because so many Bluetooth devices are small-scale and do not have space for big batteries. This allows you to make use of your gadget for extended periods of time before you must switch batteries or recharge.

There are 3 primary versions of Bluetooth, all variations are backwards compatible with preceding versions.

Bluetooth v1: Bluetooth had a difficult start. It was without critical security, was sluggish, as well as was susceptible to interference. Throughout subsequent revisions v1.1 in addition to v1.2, a number of these initial bugs ended up repaired.

Bluetooth v2: Launched in ’04, the main difference in this particular variation was faster data transfer without influencing energy utilization. In revision v2.1 secure simple sharing was initially announced which enhanced the pairing experience whilst strengthening security.

Bluetooth v3: Adopted through the SIG during 2009, Bluetooth 3.0 transfer of data as high as 24 Mbit/s, eight times faster in comparison with version 2. This can be done by incorporating the Bluetooth together with 802.11 Wireless technology. Look for Bluetooth equipment featuring a +HS on the container, that means the unit supports this new high speed technology.

Bluetooth utilizes a frequency-hopping spread spectrum radio technology to be able to communicate wirelessly between a master piece of equipment and up to seven slave products. This means that your primary component, whether it be a smart phone, a laptop, or and mp3 player, may have as many as seven different Bluetooth devices linked to it all at once.

Some examples of this include a wireless mouse and keyboard for your pc, or perhaps wireless stereo speakers for your home music system.

Given that Bluetooth technology has such a close range, it consumes little power. This is very important, because so many Bluetooth products are compact and don’t have room for big batteries. This enables you to make use of your product for extended amounts of time until you have to switch batteries or charge.

It was inevitable that technological increases will clash with the rules of the traditional classroom, and no example is more pertinent than whether cell phones should be permitted in schools. Without historical precedent to determine a course or action, the only recourse is to weigh the pros and cons against each other and logically determine a reasonable conclusion.

A damning consideration against cell phone use in schools is the fact that, with smart phones, students can cheat during tests. It’s not hard to access Wikipedia or text message someone in the class for assistance. However, there is really nothing new here, even if the medium is different. It’s not really harder to glance at a screen than it is a well prepared cheat note. Besides, it’s easy for teachers to collect cell phones on test days, and vigilantly keeping guard against cheating is something teachers have to do anyway.

The strongest and most obvious case against cell phone possession in class is their distracting nature. Even if the ringer is turned off (something students frequently forget to do), text messaging is so ubiquitous and subtle that it’s hard for teachers to control. But teachers have contended against inventive distractions for decades, and even if smart phones are more advanced than passing notes it isn’t fundamentally very different. From the students perspective, they’re motivated by the same urge.

On the positive side, every school has a lockdown procedure in the event of an emergency. While it’s true that varying messages can cause confusion and worry amongst parents and outsiders concern for students, the ability to contact police immediately outweighs this concern. In the tragic event of a school shooting, warnings can be sent from classroom to classroom and a line can be established warning police. Yes, it’s possible for students to give false alarms and mischievously cause delay in the classrooms, but the real possibility of saving lives must be given more prominence than the disadvantages of student nuisance (something they don’t need cell phones to cause anyway).

Cell phones have provided benefits that a couple decades ago would have been considered unimaginable to attain on a wide scale. For years, schools were looking for ways to fund computers in the classroom and people protested the gap between the public and private schools’ ability to do this. Even in inner city schools, it’s not uncommon to have a student in each classroom with the ability to use the internet as a resource on behalf of the class. Even where this isn’t the case, smart phones are going to get cheaper and cheaper.

Cell phones have the ability to amplify historic problems of distraction, nuisance, and cheating. These problems create the need for modified solutions for the old problems. But the positive aspects they can deliver are new and groundbreaking. It would be a shame to allow fear and reservation to prevent us from enjoying such obvious benefits. We need visionaries uninhibited by reactionary attachments to tradition to guide policy concerning the implementation of technical advances in the classroom.
