Wireless Network

Wireless Network

A wireless network uses radio signals to communicate with other network devices. It can be termed as WLAN. Well, the wireless network is increasing in its popularity because it requires no cabling and it is easy to set up. A wireless network allows other devices to get connected to the network. Its access points amplify the signals hence it makes it more convenient to access the network so long as you are within network coverage. Therefore, in this article, I will highlight some key aspects that are key to wireless networks. So let’s get into it.

How Do wireless networks work?

Wireless networks work using the electromagnetic spectrum which works using radio frequency technology. An electromagnetic field is created when radiofrequency is transmitted to the antenna. Therefore, for the wireless network to work there should be an access point where the signals are broadcasted. This is to serve as a link to devices that are within the wireless connection. Therefore for divorced to connected to the wireless network they should have network adapters. They change data into radio signals then transmit them using an antenna.

It is important to familiarize yourself with wireless technology standards because there are several networking standards. Additionally, before purchasing any device that supports wireless networks you should take note of the speed and range. This is because you will experience strong signals when you are closer to the access point.

Types of wireless networks

A wireless network is useful since it allows communication over the network. Well, the following are the types of wireless networks.

Wireless Local Area Networks

This network links more than two devices via an access point. The signals are distributed to provide a wider internet. Therefore it allows users within the area to gain access to the internet. It is commonly used in libraries or campuses. If there is a small number of users there is no need of having an access point. Instead, a Temporary network can be formed though they will be unable to access network resources.

Wireless Wide Area Networks

This network covers a wider area like cities via antenna sites or multiple satellite systems which are coordinated by an ISP.

Wireless Personal Area Networks

This network uses the current technologies of wireless network which includes Bluetooth and infrared. This network allows connectivity of devices within a range of 30 ft. Besides, Infrared has a shorter range and it requires a direct line.

Wireless Metropolitan Area Networks

This technology connects several wireless LANs.It allows connections in a metropolitan area. This can be a backup for laying a chopper.

Therefore all these types of networks convey information irrespective of the type.

What are the regulations on wireless networking

The number of access points determines the demands of the users. Areas with a high density of users require more access points. Additionally, network reliability is necessary for sufficient connection among the users. Security is also vital for wireless networks. Therefore, network access logs should be maintained so that users can log in using a username and a password. This is to prevent unauthorized access to the network. An unsecured computer has issues due to bandwidth usage.

The following are some of the standards in wireless networking.

Distance

The basic distance of a wireless network is about 30 meters and 90 meters for connections of a higher range.

Speed

The 802.11n Standard has the highest data transmission speed. It offers a speed of about 600 Mbps. On the other hand, 802.11a has a speed of 54 Mbps.

Latency

This is the time that it takes for data to be transmitted to the receiver. It can be known as a delay. Additionally, it can be altered by multiple access mode which holds the transmission.

Frequency

The frequency of a wireless device is not set directly. Well, there exist two frequency bands for the 802.11 families. They include 5GHZ and 2.4 GHz.

Channels

The wireless standards use the 5 and 2.4 GHz bands which provide enhanced bandwidth. The combination of these frequencies at the end-user is termed as the channel.

Conclusion

Sonify wireless network is a competent wireless network because of its extensive coverage and availability because of its efficient data transmission. A wireless network is a cheaper way to access the internet. You don’t need to purchase cables. Its access and availability have also been enhanced with the use of adaptors. The wireless technology increases efficiency through improved data communications which leads to faster transmission of information.

Cellular Systems

Introduction

A cellular system is a wireless communication in which several cells are installed with low power radio aerials or antennas that are normally located at a particular geographical area and interconnected to a midpoint exchange. As a cell phone receiver moves from one place to another and its radio frequency, identity, and location is handed by the cell to another without interrupting a call. Cellular technology systems need to be set up efficiently since the number of people using cellular systems is increasing day in day out. Here are some of the basic units found in a cellular system.

Basic units of a cellular system

Mobile station
A mobile station is typically a wireless mobile device that contains a transceiver, control unit and an antenna system for voice and data transmission. For instance, in GCM networks the mobile unit will contain a sim card and mobile equipment.

Base station
This is a fixed station for mobile cellular systems and it’s used for mobile units and radio communications. It consists of transmitters, radio receivers and radio channels mounted on top of a tower.

Gateway
Gateway is another unit or component of the cellular system. It refers to communication links between wired and wireless systems or two wireless systems. Two logical elements found in the gateway is the interworking function and the mobile switching center. The mobile switching center connects the mobile stations and the cellular base stations to other mobile switching centers or public telephone networks.

Databases
Databases are another significant unit in cellular systems. They are used to keep track of important information such as caller location, billing and subscriber data. There are two major databases known as the visitor location register and the home location register. The VLR stores information temporarily about the subscriber visiting the coverage area of the mobile switching center.

The main reason for using cellular systems

The cellular systems have a high number of users, high capacity and excellent network speed. The majority of people are using cellular systems since they have an increased bandwidth which leads to the transfer of data at very high speeds. The fast, uninterrupted, superior internet connectivity, providing by business NBN, is an advantage to mobile users undertaking a video conference and or a chat. The cellular systems also cover a much larger coverage than other systems such as wifi. It is also safe, secure and private an as well as not being vulnerable to any internet security threats.

How does cellular data work?

Cellular data refers to a communication network linked by wireless systems. The network or data is distributed over cells each served by a fixed-location transceiver. The base station or unit provides the cell with network coverage used for data and voice transmission. A cell normally uses a distinct set of frequencies from the neighboring cells to provide each cell with guaranteed service quality and avoid interference. Cellular data utilizes the network provided from the cell towers for communication through phone calls and internet connectivity.

What is interference in the cellular system?

In wireless networks or cellular networks, interference refers to a disruptive signal that travels in a disruptive manner along a channel between its receiver and the source. They are also unwanted signals that cause disturbance in the cellular systems causing inconveniences in the network systems. Some various types of interference include multiple access interference, adjacent channel interference, and self-interference.
