Can You Recommend The Best 2 Way Radios For A University?

by: luke1975   Keywords: school, communications

Your best bet, be it for general use in academic studies, health and safety concerns or simply security, would be to http://www.bicolradio.org/?p=77 - employ a digital two-way radio system - , something like the Motorola SL4000. I’m specifically suggesting Motorola because they handle jobs like this all the time, several of which are detailed on their website.

In fact, the Motorola website details a case almost exactly like yours, where this technology was employed to great effect.

According to the site, the Cincinnati State Technical and Community College (CSTCC) was in a situation just like the one you outlined in your email. Here’s the basic issue...

http://www.motorolasolutions.com/web/Business/Product%20Lines/MOTOTrbo/_Documents/Case_Studies/Static_Files/Education_CSTCC_College_Campus.pdf - “CSTCC is comprised of three campuses and over 1.3 million square feet.  - http://www.motorolasolutions.com/web/Business/Product%20Lines/MOTOTrbo/_Documents/Case_Studies/Static_Files/Education_CSTCC_College_Campus.pdf - Until recently, the college used an all-analog system, components of which  - http://www.motorolasolutions.com/web/Business/Product%20Lines/MOTOTrbo/_Documents/Case_Studies/Static_Files/Education_CSTCC_College_Campus.pdf - were 15 years old.  According to Raymond Mirizzi, Director of Facilities at - http://www.motorolasolutions.com/web/Business/Product%20Lines/MOTOTrbo/_Documents/Case_Studies/Static_Files/Education_CSTCC_College_Campus.pdf - CSTCC, “We needed to upgrade our whole communications system,” and it  - http://www.motorolasolutions.com/web/Business/Product%20Lines/MOTOTrbo/_Documents/Case_Studies/Static_Files/Education_CSTCC_College_Campus.pdf - was vital that the entire campus be covered with a radio solution that would  - http://www.motorolasolutions.com/web/Business/Product%20Lines/MOTOTrbo/_Documents/Case_Studies/Static_Files/Education_CSTCC_College_Campus.pdf - support very clear, consistent and secure communications”. -

How a two-way radio network helped the situation is also detailed.

There are lots of companies other than Motorola, of course, but there’s no denying that they are giants in their field, with a long history of customer satisfaction. They are something like The ‘A’ Team in that respect. Still, if your budget doesn’t quite allow for bells and whistles, there are a number of quality independent firms that could do a very good job at a slightly more reasonable rate.

The reality here is that bargains are the exception, not the rule. That’s why we’re always so happy when we get one. By far your best bet is to get an expert to design and implement your faculty’s new communications method. It needn’t be the biggest company, but you want to spend a good amount on communications, as they really do save lives.

Walkie Talkie vs Two Way Radio?

by: luke1975   Keywords: Walkie, Talkie, vs, Two, Way, Radio

Although the terms walkie-talkie and two-way radio can be used interchangeably, some minor differences between the two technologies do actually exist. In a professional context, it is best to know which device you are referring to before you refer to it (but this is substantially less important on a day-to-day level).

Essentially, a walkie-talkie is the same as a two-way radio; there is no overt difference between the two. However, because there are so many different radios on the market, a distinction has arisen. The - term walkie-talkie tends to imply - a hobby model, or an otherwise cheap radio. Conversely, the term two-way radio tends to be more readily accepted in a business, as well as any equipment specific, context.

Walkie-talkies were invented around the time of the Second World War and were principally used by the military. Although they came in different forms, the most common version featured a large handset, which had a long antenna protruding from it. Modern walkie-talkies, on the other hand, feature a smaller design, typically with a rugged outer casing and a short aerial. They usually operate via a PTT ( http://en.wikipedia.org/wiki/Push-to-talk - Push To Talk - ) button and available models vary in range from cheap childrens toys to professional, military grade equipment.

Generally, walkie-talkies are limited to only a few watts of power and a relatively short signal range. To this end, radio services often use a repeater (a device that increases range and boosts signal by squashing unused frequencies) in order to improve the walkie-talkies operation.

For their part, two-way radios, although they are also portable hand-held transceivers (a device that can both  http://www.bbc.co.uk/schools/gcsebitesize/science/add_ocr_pre_2011/wave_model/waveinformationrev1.shtml - TRANSmit and reCEIVE messages - ) and they also use the PTT system, are slightly different.

A two-way radio is likely to have a stronger range and a harder outer casing. This is because the term two-way radio denotes a better class of product (usually).

Some two-way radios are also capable of sending and receiving messages at the same time; this is called full duplex An example would be a mobile phone, which employs two different radio frequencies at the same time. However, although a mobile phone is technically a two-way radio, the device is very different from what we understand as either a walkie-talkie or a two-way.

The most important distinction is that two-way radio almost always refers to professional, licensed equipment, whereas walkie-talkie more often describes unlicensed, consumer-grade radios.
