There are two common wireless network connection types namely fixed wire replacement and ad hoc networks. Fixed wire replacement being a LAN adopting wireless connection where otherwise would have been a wired LAN due to constant layout changes or cost. Ad hoc network simply is a real and full wireless LAN with port-to-port connections. Fig 3.0 Some of the benefits of Wireless LAN are as follows: * Simplified implementation and Maintenance – Less expensive and useful in places with constraints for laying cabling. * Extended reach – Users are able to connect to the Network resources from any location within the Network AP (Access point) transmission range.
VOIP phones- voice over internet protocol is a technology that allows phone calls to be made through the internet. An advantage of this system is that there is no additional charge for phone calls beyond the charge for the internet through its service provider. VOIP uses a data network. Skype/Facetime- is a VOIP software application that allows for calls to be made over the
Unit 8 Discussion 1 802.11 a/b/g/n - The 802.11 family consists of a series of over-the-air modulation techniques that use the same basic protocol. The most popular are those defined by the 802.11b and 802.11g protocols, which are amendments to the original standard. 802.11-1997 was the first wireless networking standard, but 802.11b was the first widely accepted one, followed by 802.11g and 802.11n. 802.11n is a new multi-streaming modulation technique. DOS, Man the Middle, and Identity theft attacks are very common with this type of network standard.
2. Define and describe the following Telecommunications Network Components: A. Voice- Voice calls are not too unlike fixed line calls; the difference being that it is transmitted wirelessly. The call is transmitted via radio waves to a cellular tower, which is then routed through the service provider and to the party on the other end. Data- Data is commonly called mobile internet. Data is sent through radio waves in either 3G or 4G connection, which streams data to and from the phone, much like a computer connects to the internet.
Advanced version of 3G technology. To exploit full potential of the CDMA physical layer. To achieve performance comparable with LTE. Having both technologies on one network with voice and data. | Radio frequency | Allows you to access information while on the move anywhere you can get a radio frequency.
* Hosts in a LAN to connect to networks and hosts outside of the LAN 8. A computer with a host IP address of 10.10.5.1 sends a data packet with a destination IP address of 10.10.5.2. A subnet mask of 255.255.255.0 is being used. Determine whether the packet stays in the LAN or is sent to the gateway. *It stays in the LAN because both IP’s have the same network ID.
DHCP is a protocol that assigns unique IP addresses to devices, then releases and renews these addresses as devices leave and re-join the network. Internet service providers usually use DHCP to help customers join their networks with minimum setup effort required. Likewise, home network equipment like broadband routers offers DHCP support for added convenience in joining home computers to local area networks (LANs). DHCP environments require a DHCP server set up with the appropriate configuration parameters for the given network. Key DHCP parameters include the range or "pool" of available IP addresses, the correct subnet masks, plus network gateway and name server addresses.
This is a company that provides connectivity to the Internet. m. Triple play: This is a reference to the bundling of Internet, TV, and Phone services by a provider. n. Cloud Computing: This is a form of computing using remote resources. Cloud computing allows a user to access a service or application without the local host doing any of the computing. An example of cloud computing would be a free email site such as Yahoo or Gmail.
