What are wireless telephone base stations - Worth The Convenience?

Fixed antennas used for wireless telecommunications are referred to as cellular base stations, cell stations, PCS (""Personal Communications Service"") stations or telephone transmission towers. These base stations consist of antennas and electronic equipment. Because the antennas need to be high in the air, they are often located on towers, poles, water tanks, or rooftops. Typical heights for freestanding base station towers are 50-200 feet.

Some base stations use antennas that look like poles, 10 to 15 feet in length, that are referred to as ""omni-directional"" antennas. These types of antennas are usually found in rural areas. In urban and suburban areas, wireless providers now more commonly use panel or sector antennas for their base stations. These antennas consist of rectangular panels, about 1 by 4 feet in dimension. The antennas are usually arranged in three groups of three antennas each. One antenna in each group is used to transmit signals to wireless phones, and the other two antennas in each group are used to receive signals from wireless phones.

At any base station site, the amount of RF energy produced depends on the number of radio channels (transmitters) per antenna and the power of each transmitter. Typically, 21 channels per antenna sector are available. For a typical cell site using sector antennas, each of the three transmitting antennas could be connected to up to 21 transmitters for a total of 63 transmitters. However, it is unlikely that all of the transmitters would be transmitting at the same time. When omni-directional antennas are used, a cellular base station could theoretically use up to 96 transmitters, but this would be very unusual, and, once again, it is unlikely that all transmitters would be in operation simultaneously. Base stations used for PCS communications generally require fewer transmitters than those used for cellular radio transmissions, since PCS carriers usually have a higher density of base station antenna sites.

Can you image being stranded somewhere by yourself? Now, if that picture
isn’t bad enough, image being stranded without your cell phone. It’s hard to believe that about 15 years ago, cell phones were practically unheard of. Wireless phones, especially cellular phones, are one of today’s best inventions. Even wireless home phones are wonderfully convenient. For all of you talkaholics, wireless phones allow you to prepare dinner, change the baby’s diaper, do the laundry, and water the garden, all while carrying on hours of conversation without missing a beat. How neat is that?

The down sides to wireless phones are that they need to be charged quite frequently. After 2-3 hours of usage, wireless phones usually need recharging. This can be especially annoying since a very important conversation could be interrupted or cut short. How many times have you been in the middle of a conversation and go “…Did you hear me,…hello, hello..”, then you realize that your call has been cut off? Then your party calls back, apologizing for the interruption. Sometimes the interruption is at no fault of either party. It is can be due to the signal being lost as well. This can also be very annoying in the event of an emergency and crucial information is being communicated.

However, there are more positive reasons why almost everybody (including your grandmother) uses some form of a wireless phone. For instance, authorities can track you down using your wireless or cell phone through frequency towers in the event of a kidnapping, accident or other emergency situation. Also traveling with and using your wireless phone out of town is another “Must Have” convenience. Don’t you agree? They are also becoming more and more compact, even in different styles, colors, features and accessories for more carrying convenience. How nice!

Overall, the conveniences of all wireless phones, whether cellular or mobile, are still well worth and out-weigh the inconveniences. In fact, cell phones have practically made pay phones obsolete. Think about it, when was the last time you saw a pay phone or one that worked? It makes you wonder what will be the next device we won’t be able to live without in the next 10 to 15 years. Guess everyone will just have to wait and see.
