The terms wireless broadband is defined by Margaret (n.d.) as “high-speed Internet and data service delivered through a wireless local area network (WLAN) or wide area network (WWAN)”. In Malaysia, there are three types of wireless broadband technology which are GPRS, UMTS/HSPA, and LTE. These three technologies will be discussed further. GPRS or General Packet Radio Services “is a packet data overlay onto existing GSM networks” (Srinath,N.,2011 as cited in A.K. Aini Zuriyati, O. Zainuddin, M.Muriati,2014 ).
Talking on a digital cell phone, a caller hears less of the sound of someone's voice. Disadvantages In less crowded areas, the weaker digital signal conveyed by a cellular phone may not be enough to reach a cell Base Station. This tends to be a specific problem on 2G systems installed on higher frequencies, but is generally not a problem on 2G systems installed on lower frequencies. National regulations vary significantly among countries which dictate where 2G can be installed (installed). Analog has a smooth decline curve, but digital has a sharp steppy one.
1.1 Wireless communication There are various generation in the wireless system. We are running with the 4 G wireless system which is more focused on the high speed data communication. The demand for higher capacity with low error has raised manifolds, mainly due to cellular telephony although expected to be soon eclipsed by wireless data applications. The various digital signal processing algorithms like IFFT, FFT can be implemented with the advent of modern chip technology. Due to the success of 2G wireless communication standards especially CDMA technique it has been shown that communication ideas can be implemented in practice .
I started meeting professors and discussed with them about my interest in telecommunications and prospective areas to do my thesis project. It was at this time I chose to pursue elective courses like Wireless Sensor Networks and took a special interest in learning courses like Wireless and Mobile Communication. I started thinking about what would be the leading technologies in the Communications industry in the years to come, and there were two obvious answers- 5G technology and Internet of things. I started reading about these technologies and challenges involved in developing them. I saw the introduction of 4G in India and how drastically the speeds went up and costs came down, moreover, when I came to know 5G would deliver speeds up to ten times faster than 4G I felt my career would be exciting and interesting if I chose this field.
GIS maps can demonstrate these authorities what neighborhoods are most in risk, where to find havens, and what courses individuals ought to take to achieve security. Use of GIS in Urban Planning The high establishment and operational expenses of GIS at first was a boundary to the reception of geospatial advances in the field of urban arranging. A network based programming known as Sinton's
The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves. Like a GSM mobile phone, a GSM modem requires a SIM card from a wireless carrier in order to operate. A GSM modem can be an external unit or a PCMCIA card (also called PC Card). An external GSM modem is connected to a PC through a serial cable, a USB cable, Bluetooth or Infrared. Like a GSM mobile phone, a GSM modem requires a SIM card from a wireless carrier in order to operate.
Improved travel experience: SWIM which uses satellite communication is more reliable and secure than current radar systems that use 'Radio frequency'. This makes the Aircrafts to be available exactly on time. By tracking Aircrafts' position, engine performance and other minor changes among the
On account of the great functions, 3G mobile communication products was called "personal communications terminal" with large color display and touch-sensitive. In addition to complete routine communications, It also works as multimedia communications. Users can write on the touch screen 3G phone, draw and send it to another phone. Apple and Samsung are the two strongest manufacturers of 3G. Oppositely, Nokia and Ericsson, the previous supper stronger manufacturers were far away behind Apple and Samsung.
We have seen increasing data speeds with each passing technology. We have obtained average data rates of 15 Mbps with 4-G technology. 4-G technology is yet to realize its full potential. On the other hand, there are talks already regarding the introduction of 5-G technology. The new 5-G technology is expected to hit the market by 2020 or maybe before that.
Introduction Mobile computing is becoming increasingly important due to the rise in the number of portable computers and the desire to have continuous network connectivity to the Internet irrespective of the physical location of the node. Mobile computing offers significant benefits for organizations that choose to integrate the technology into their fixed organizational information system. Ranging from wireless laptops to cellular phones and Wi-Fi/Bluetooth enabled PDA’s to wireless sensor networks, mobile computing has become ubiquitous in its impact on our daily lives. Mobile computing is a versatile and potentially strategic technology that improves information quality and accessibility, increases operational efficiency, and enhances management
