| | 5. Research the status of 3G and 4G cellular service by visiting www.itu.int and www.4g.co.uk and www.3gnewsroom.com. Prepare a report (one paragraph) on the status of 3G and 4G service based on your findings. Answer 3G network is very advanced smart phone which has a variety of functions such as web browsing, instant messaging, access to emails, it give you option and allows you to download music, these functions are also similar to the functions of the 4G. The difference between the two are that the 3g speeds can usually reach up around 3 mbps wheres as the 4g has an average speed around
The 802.11b specification affects only the physical layer, adding higher data rates and more robust connectivity. .Wireless-N broadband routers cost more and offer the fastest speed and longest range. These routers cost anywhere from $70 to $170 depending on what features and capabilities get implemented. The D-Link DIR-655 Extreme N Wireless Router at $90 is good choice. The higher priced Netgear Rangemax WNDR3700 Dual Band Wireless-N Gigabit Router at $160 offers twice the bandwidth using Netgear's RangeMax technology.
IS 589 Course Project Professor James Marion VoIP Implementation and Quality/Latency Issues Gaines Williams Introduction The term VoIP stands for voice over Internet Protocol. VoIP is related to the terms IP telephony and Internet telephony. At the most basic level, VoIP technologies enable analog telephone communications to be digitally transferred and routed over data networks—this can be done over a wide area network (WAN), a local area network (LAN) or the Internet. These two packets of communications, digitized voice and data, coexist and travel throughout a network. A third packet, video, has become an increasingly important network consideration for organizations because of its large bandwidth requirements.
Name:ID: Email: Chapter 1 CIS 30 True/False:Indicate whether the statement is true or false. 1:Data is information that has been translated into a form that is more conducive to storage, transmission, and calculation. True 2:Some people call computer terminals thick-client workstations. False 3:A type of microcomputer-to-local area network connection that is growing in popularity is the wireless connection. True 4:To communicate with the Internet using a dial-up modem, a user’s computer must connect to another computer that is already communicating with the Internet.
Already in place, can be very cheap to use | Coaxial | Television cable | Must run cable to all locations, can carry much higher speeds than Telco. Is a little more expensive to run. Needs boosters at specific distances | Fiber-optic | Glass cables with POP’s at specific distances | Uses a customized infrastructure to run dedicated connections: this is a costly option | Electric power lines | Power lines. They are everywhere and the infrastructure is already there | This type of media can be used with Broadband over Power Lines (BPL), making use of the extensive infrastructure in place already | Table 7-2 WAN Wireless Media Media | Summary | Satellite | Not very fast, has a delay of about 1 second, very costly to use. Uses a star topology | Imax (Worldwide Interoperability for Microwave Access) | This has 75Mbps speeds and can transmit for distances up to 30 miles.
WAP are common in all wireless networks but having more than one in larger networks is considered a benefit for the network. Wireless routers are most of the time considered as wireless access points.
The 3G service that people are using today is at least fast now compared to a year ago. More subscribers are tapping into the network with more data devices. The new generation of 4G wireless services is becoming coming in the country’s popular areas. PC World had done a study which showed that most of the wireless network operators are investing in 3G networks. (Retrieved from http://www.pcworld.com/article/253808/3g_and_4g_wireless_speed_showdown_which_networks_are_fastest.html) The studies consisted of AT&T, Sprint, T-Mobile, and Verizon.
Week 1 Individual Assignment NTC/405 * * What widely used networking protocols support or make possible video calls also known as video teleconferencing? What role does each protocol play in the video call process? Include basic connectivity roles. * Standard voice and video protocols used on VTC systems today are the Session Initiation Protocol (SIP), H.320, and H.323. What role does each protocol play in the video call process?
* Verizon Wireless Strategy is the having the best Network. Thus, the core competencies will be built around the network. Things like RF Engineers and wireless security experts would be detailed * Intel's strategy is to build the fastest most powerful CPUs. Thus their core competencies will be built around CPU engineering * Keller's strategy is to deploy the best on-line education technology. Thus their core competencies would be things like educational technology evaluation and on-line education curriculum development The best way to do this section is to apply the three tests of a core competency (page 123) to the strategy that you detailed in the Strategy Section.
DSL Type | Description | Maximum download speed | Minimum Upload speed | Maximum Distance (m) | ( ADSL) – ADSL2+ | This has a much higher download speed than upload speed based on traffic statistics. | 24 Mbps | 1.4 Mbps | 6000+ | High- bit- rate DSL ( HDSL) | This is comparable in performance to a T1 line; it has the same upload and download rate but requires two lines. | 2320Kbps | 2320Kbps | 12,000 | ISDN DSL ( IDSL) | This type of DSL operates at a fixed rate for both upload and download; it is primarily for users of Integrated | 128Kbps | 144 Kbps | 10,700 | DSL Type | DSL Type | Maximum download speed | Minimum Upload speed | Maximum Distance | Multirate Symmetric DSL (MSDSL) | This is a symmetric DSL type that is capable of more than one transfer rate. | 2.32 Mbps | 160kbps | 29,000 | Rate Adaptive DSL ( RADSL) | This is an asynchronous DSL type that can adjust speeds based on the length and quality of the connection line. | 8 Mbit/s | 1 Mbit/s | (8) kilometers (5 mi) | Symmetric DSL ( SDSL) | This type of DSL sends and receives data at the same rate | 2.048 Mbps | 2.048Mbps | 3000
