Broadband Access Through Cable

Broadband access through cable

Broadband is defined as a mode of data transmission, where multiple data packets are sent simultaneously to increase the effective rate of transmission.Intelligent use of your TV cable has lead to the emergence of cable broadband. This technology works by making use of the unused bandwidth in your CAT V cable. As the cost of networking is eliminated, cable broadband is one of the cheapest ways to log on to the internet.

Advantages of cable modem:

– Cheaper as compared to other broadband technologies

– Doesn’t use your phone line in any way

– No dial-up procedures to be followed

– Unlike ADSL, signal strength not a variable of distance

– Reliable

– Optimum speeds

All you would require to avail, these benefits is a cable modem; this modem will act as your gate way to the cable company’s network. Connect your PC to the modem which in turn will log you on to World Wide Web.

Disadvantages of cable modem:

The main limitation is its reach; areas not covered by CATV network are also deprived of this cheap service. The other disadvantage being that the signal strength depends on the number of people logged on to the network, as more the people more the bandwidth required and with a cable that surely is limited.

Fixed Wireless Broadband Access

Fixed wireless is a method of transmission of high speed data traffic via a wireless connection between two fixed points. Subscriber service consists of a microwave antenna and radio on customer’s rooftop for transmitting and receiving RF signals. The customer’s antenna points to the service provider’s RF transceiver (Access Point) located on the radio tower or tall building. Fixed wireless connection with customer has clear Line of Sight (LOS) to the Access Point can reach distance up to 50 miles and data rate up to hundreds of Mbps.

Fixed Wireless has two configurations, point-to-point (PtP) or point-to-multipoint (PtMP). PtP networking connects two locations by using two radios and two antennas dedicated to only each other. PtMP networking refers to communications between one access point and multiple customer radios. Fixed wireless can use frequency either in licensed band or unlicensed band. Unlicensed band frequencies of 900MHz (902-928), 2.4GHz, 5.3GHz, 5.4GHz, 5.8GHz, 24GHz, and 60GHz are exempt from FCC licensing requirement. Unlicensed wireless systems, although quick to deploy, do not promise exclusive use of the band and are susceptible to potential interference. Licensed microwave wireless systems operate within parts of the radio spectrum (VHF, 900MHz, 2GHz, 3.65GHz, 4.9GHz, 6GHz, 7GHz, 11GHz, 13GHz, 18GHz, 23GHz, and 80GHz) designated by the FCC. To operate a licensed microwave fixed wireless radio system, one must apply for a license from the FCC. Licensed operators are permitted exclusive use of part of the band over an assigned geographic area.

Fixed Wireless Broadband is designed to emulate coaxial cable connection and support both TDM and packet traffic such as T1, T3, frame relay, Ethernet and ATM. High-capacity carrier-grade wireless backhaul radio combines TDM with Ethernet to provide smooth evolution to advanced, packet-based radio performance and facilitating cost effective, risk-free migration to IP/Ethernet. Enhanced Fixed Wireless can deliver Internet, Voice and MPLS, all with guaranteed Service Level Agreements. The advantages of fixed wireless include lower costs, greater flexibility, and faster deployment. Reliability is on a par with wireline networks and can be engineered to achieve 99.999% availability. Service carriers go to great lengths to ensure secure data transmission through the use of high-gain directional antennas tightly focusing the signal and directing it precisely at the customer’s CPE. Fixed Wireless Broadband transmits and receives encrypted signals from specific, authenticated devices only. It employs the Advanced Encryption Standard (AES), which is the standard adopted by the U.S. government to protect its data. Hence, fixed-wireless data transmission using AES are as secure as any transmission in the world.

Latest technology innovation has made fixed wireless a competitive mode of broadband delivery in increasingly high density environments such as the suburban, urban, and enterprise customers. Multiple Input Multiple Output or MIMO technology has enabled the rapid growth in bandwidth capacity by continually improving spectrum efficiency with the addition of more and more MIMO streams and smart antenna array technologies. Antenna beamforming is a crucial technology enabling the spectrum used by an access point to be reused by multiple clients simultaneously. Beamforming uses precise geoposition information from each wireless client to focus wireless antenna transmit signals towards each unique client, achieving improved focused wireless signals, and significantly reducing interference in the spectrum. Because beamforming isolates client signals, it creates spatial opportunities in the spectrum for additional MIMO streams to be used simultaneously using SDMA (Space Division Multiple Access). This is called Multi-User (MU-) MIMO. When downstream traffic arrives for multiple clients, the access point identifies geolocation based beamforming opportunities to service those clients simultaneously, drastically improves the capacity of the radios. MU-MINO enables fixed wireless to deliver fiberlike broadband connectivity at a fraction of the cost of traditional wireline solutions, in any environment, from low-density rural broadband to high-capacity, high-reliability business connectivity for the enterprise.

High Speed Satellite Internet Access for Rural America

Do you feel the need for high speed Internet access and simply can’t get it? Not every home has access to DSL or Cable broadband Internet access services. In fact over 30 million people still can’t receive high speed Internet access. The costs of setting up DSL or cable access throughout the country, to each home, are in the billions of dollars. There are many promises that DSL or cable is coming, but when. Unfortunately it all boils down to economics, too few subscribers with too many miles. To many, satellite Internet access offers the solution. Satellite Internet service allows virtually everyone, anywhere to have access to lightning-fast broadband Internet access. There are two types of satellite Internet service, “one way” and “two way” systems.

With two way satellite systems the satellite dish sends and receives information over the Internet and delivers it your computer. The real benefit of a two way system is that you’re able to receive high speed access without tying up your phone line. Two way satellite service also give you an always on system. Download speeds can be as high as 1.5mpbs with upload speed about 128kbps.

One way satellite Internet access utilizes a dial up connection for upload page requests and offers similar download speeds of 256kbps to 1.5mbps. One way satellite Internet access is more reliable and economical than two-way satellite Internet services. It’s faster and more reliable because one way satellite Internet doesn’t experience the same time-out delays caused by “two-way” approach of uploading requests to the satellite. Satellites are really designed to broadcast and not receive information from small transmitters. One way satellite service takes advantage of satellite’s strengths by using it for downloading of information only. As you know, when you’re using a dial-up Internet service, your waiting time is based on downloading the information over your telephone line. The use of satellite Internet to download eliminates the problem.

If you are uploading tremendous amounts of information then a two way satellite system may be right for you. On the other hand, for average to moderate Internet surfers, one way satellite Internet access offers high speed that is reliable and much more affordable than two way access. Because of the simplicity and reliability, one way satellite Internet access is not regulated by the FCC. This gives the flexibility of choice of professional or self installation.

Put an end to your slow Internet access. Satellite Internet access may very well be the answer that you were looking for.
