The Lan And A Wan

When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.

Each location has its own local network thus it is distributed across the company, however this has its pros and cons that can affect the company. With the implementation of a WAN as defined in Telecommunications Essentials “A wide area network (WAN) is a group of computer networks connected over long distances by telecommunications links, which can be either wireline or wireless.” (Goleniewski & Jarrett, 2007, p. 201) The benefits that a WAN will bring to Kudler Fine Foods is a centralized management of all systems and an ease of use communication from store to store. As stated earlier along with the WAN, each location will also be implementing a WLAN. This shall improve network coverage and give each location the ability to place computer systems or POS machines in locations that may have not been possible before due to the lack of a hardline or ability to install a new line. Wireless technology has greatly improved over the years and has transitioned from an additional layer that may not be needed or only added if there was room in the budget to a

6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?

LANs standards and protocols are Ethernet, IEEE 802.2 [IEEE 802.3, 100BaseT, Token Ring/IEEE 802.5 and FDDI.

2. Which of the following are services that telcos have offered as WAN services over the years?

4G networks offer 10 or more times the data transmission rate of a 3G network. The data rates available on a 4G network allow the cell phone to access information from the Internet as fast as a land-line connection.

Installation of wireless networks are relatively easy - they often simply involve playing a wireless access point in a place where the signal reaches the most areas. In more advanced installations, it is common to use a radio mapper to determine where the signal does and does not reach, for practicality and security reasons. The power of the router is important to consider and often can be adjusted on the software side to suit the

Considering that 75 percent of mobile data use comes from streaming videos, Telstra’s wireless LTE roll out would be huge, as reported by the Financial Review. Gigabit LTE would roll out first in the inner metro areas. However, there is no official information yet if mobile internet plans will be updated with the faster speeds. But the fast speed will not be accessible from mobile phones. Which is why Telstra’s move also prompts Netgear to launch the first Gigabit LTE device called the Nighthawk M1 mobile router which will cost $360. This is because current smart phones in the market cannot access Gigabit LTE.

WAN and LAN has wired and wireless options such as Router with firewall/IPS, integrated Ethernet switch, compact switch, Power-over-Ethernet (PoE), outsourcing internet provider

Mobile and fixed networks are now both extremely developed in today’s modern world. It is now completely possible to get blazing fast internet with wither a fixed line provider, or a mobile provider. The services provide more than internet though, also frequently providing phone and/or television services. These networks are far from perfect though.

Differentiate among major types of LAN and WAN technologies and specifications and determine how each is used in a data network.

The evolution of 3G technologies and system into 4G evolution is driven by the development and creation of latest and upgraded services for the mobile devices, and is enabled by this similar advancement for the respective mobile systems. The development of LTE and LTE-Advanced technologies, with 'Advanced' specifying the only difference between LTE release 10 /LTE Advanced and ITU/IMT-Advanced. The work on developing these technologies- LTE and LTE Advanced is performed as an ongoing continuous task within the 3GPP, the same organization the developed the first 3G system namely WCDMA and HSPA.

The organization works on 2.5G, 3G, 3.5G, and 4G LTE correspondences arranges and turn into the principal administrator to dispatch business 3G and HSDPA+ operations in south Asia when it rollout the system in 16 August, 2006. In April 2013 Dialog Axiata propelled its versatile 4G LTE administrations utilizing 10 MHz of range in 1800Mhz band turn into the primary administrator to dispatch business DF – LTE arrange in south Asia, at first conveying crest information rates of 50Mbit/s its position as innovation initiative among its provincial
