Two Way Radios - Cost-Effective Means of Staying Connected

two way radios are slowly becoming an integral part of our lives. The benefits of using them have been realised not only in the commercial sphere but in personal interaction as well. Despite the fact that they are limited by a fixed frequency, which limits their range of functioning, they are still emerging as a popular communication device. The reason probably is that the price range of these handsets is substantially lower than a mobile phone, and the user also does not need to pay for any of the calls made to the other handset.

There are numerous two way radios available in the market with frequencies ranging from one mile to 15 miles. In fact the technology used in radio handsets that are used for commercial purposes (in offices, etc.) and the ones used by a family are completely different.

The General mobile Radio service (GMRS) is the type of two way radios that are used for outdoor or commercial purposes. They have been in use since the 1940s and the major advantage of using these is that they have the ability to transmit between five to ten miles. Because of the greater range covered by them, they are ideal for professionals who have a travelling job profile, like people in sales and marketing. Even police men and soldiers find great use for this type of two way radios. They transmit at higher power levels of one to five watts and are more expensive than other types of radio handsets.

The other type of two way radios is the one used for personal/family communication. This type is called the family Radio service (FRS) and was created in 1996. They are specifically used for communication within a small area, and that is why their frequency range is a maximum of two miles. They are also less expensive than GMRS bands and have a maximum power output of watt (500 milliwatts). Generally radios sets these days have only FRS or a combination of FRS and GMRS.

One thing to be kept in mind while using FRS and GMRS two way radios is that while no license is required to use the FRS band, the user of the GMRS band service requires a GMRS license.

This information will allow you to compare water filtration systems for your home. It will provide you with information about water usage and cost per gallon.

The performance testing data sheet will also provide statistics regarding the amount of VOCs and THMs that are removed from the water. It should also provide you with percentages of chlorine and minerals left in the water that has been filtered. Additionally, the data sheet should tell you the PH level of the water, and explain whether or not the finished product is PH balanced for optimum health.
