Nevertheless, some of the company already provide registration with Federal Communication Commission before the equipments are set up. Thus, there would be no more further registration for two-way radio communication.

Cost of setting up an operating the system

Licensing Cost

There are three types of areas for licensing the two-way radio. They include rural area, sub urban area, highly populated area. Licensing Cost for the rural area will vary from ￡75-80 per year. Licensing Cost for the sub urban area will vary from ￡100-120 per year. Licensing Cost for the highly populated area will vary from ￡200-220 per year.

Equipment Cost

Equipment cost for the two way radio communication will be vary from the type of two way radios that chosen by the Townsville Police Department. From the scenario, the Townsville police department is divided into four districts. Each district has five police car for patrolling the area and police officer also patrol local area on foot. Townsville police department has a serious crimes squad which has eight cars. These patrolling cars and police officers require two-way voice communication. Thus, the department provide them with two way radios which govern an area of 100 square kilometres.

For all the 20 patrolling cars and 8 serious crime squad cars, the 28 transceiver will be necessitated. Each transceiver will cost around ￡85, so all the transceiver s for the cars will be around ￡2380.

For the police officers, two-way radio which can operate 25 miles will be needed. Each of these two-way radios will cost around ￡40.

Limitation of each method

Two way radios communication can be used on both Very high frequency and Ultra high frequency. Both VHF and UHF frequencies are covered around four mile of range. VHF waves are not very strong for penetrating walls, structures and rocky landscape. So range will be reduced for VHF radios in these environments. That may not necessarily be a problem if the range needed is only around a hundred feet. Anything that frustrates a radio wave will weaken a radio signal. UHF lessens that effect. Though it may not go as far, UHF radio waves will penetrate obstacles better than VHF. One advantage of UHF transmission is the physically short wave that is produced by the high frequency. That means the antenna on the radio can be shorter than an equivalent VHF radio.

Recommendation

As Townsville is a populated area, VHF can't perform well because as a city there has many complex radio transmissions and broadcastings. VHF cannot penetrate through the buildings and structures and the communicating security cannot get safety. And most VHF radios are half duplex. For the UHF, the frequencies are extremely high and the penetrating ability is more immense. And, the distance limitations between VHF and UHF are quite different. UHF can go more distant location and can perform effectively for 24 hour. For the above reasons, I suggested Ultra High Frequency (UHF) is more suitable for The Townsville本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
