3. What is Satellite
Satellite internet uses a satellite dish for two-way data communication.
Satellite internet is a high speed internet solution that is available to people in rural areas.
Two-way satellite internet uses IP multicasting meaning that up to 5,000 channels of communication can be instantaneously served by one satellite.

4. Advantages/Disadvantages of Satellite
Available anywhere
5x-10x faster than Dial-Up
No phone line required
Can use your satellite TV dish for sending and receiving signals
Signal effected by wind, rain, snow, line-of-sight
High Latency
Slower than DSL
High Startup Cost
High Monthly Cost
Limited Download and Upload

802.11
802.11a
802.11b
802.11g
802.11n

8. 802.11
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) created the first WLAN standard.
only supported a maximum network bandwidth of 2 Mbps
Unregulated frequency of 2.4GHz
Can have interference from home appliances
too slow for most applications. For this reason, ordinary wireless products are no longer manufactured.

9. 802.11a
1999, IEEE created the a
802.11a supports bandwidth up to 54Mbps
Regulated frequency of 5GHz
Higher frequency = shorter range + difficult to penetrate through walls.
More commonly used by business due to higher cost

10. 802.11b Also created in 1999 (same time as 802.11a)
Support bandwidth up to 11Mbps
comparable to traditional Ethernet
Unregulated radio frequency of 2.4GHz
Good Signal range
Can incur interference from Microwave ovens, cordless phones and other appliances
Can be avoided by distancing appliances
Commonly used for home network

11. 802.11g
2003 – Newer WLAN standard called emerged on the market.
Combination of best of a and b
Supports bandwidth up to 54Mbps and it uses 2.4Ghz frequency
Fully backwards compatible with b hardware
Summer 2003: dual-band/tri-mode supporting a/b/g in a single access point.

12. 802.11n October 2009 – approved and published the 802.11n
Main improvement:
Addition of Multiple-input multiple output (MIMO)
Increased data throughput
Increased range by exploiting the spatial diversity through coding schemes.
Frequencies used: 2.4GHz and 5GHz or Mixed
Support bandwidth of 300Mbps
The newest IEEE standard in the Wi-Fi category is n. It was designed to improve on g in the amount of bandwidth supported by utilizing multiple wireless signals and antennas (called MIMO technology) instead of one.

16. 802.16 (Wimax) Worldwide Interoperability for Microwave Access (WiMAX)
Combines the high speed of a broadband connection with the convenience of mobile internet connectivity
Provides performance similar to /Wi-Fi networks
Provides broadband wireless access up to 50 km for fixed stations km for mobile stations

17. Wimax Diagram

18. 802.16 (Wimax) Advantages Disadvantages
Single station can serve hundreds of users.
Much faster deployment of new users
Speed of 10Mbps at 10 km’s
It is standardized (same frequency equipment)
Less expensive when starting from scratch
No SIM card required
Supports targets up to 125/khr
Line of sight needed
Weather conditions
Other wireless equipment
Strong electrical support
Costly
Higher Latency
Not widely accepted worldwide
Handover and roaming hard to achieve

19. What is LTE? LTE is an acronym for Long Term Evolution
LTE and WiMax combine to under the 4G umbrella
LTE is an upgrade of UMTS (Universal Mobile Telecommunication System) which was developed in Europe. UMTS uses HSPA (High Speed Packet Access) and is considered 3G technology. HSPA and UMTS are sometimes used interchangeably and are networks that support both HSDPA and HSUPA.
LTE uses CDMA (Code Division Multiple Access) multiplexing that is based on mathematics rather than time slicing (used by TDMA) or frequency hopping

21. Evolution of LTE

22. LTE Advantages Disadvantages Small coverage area in US
Applications perform better and faster
Decreases the traffic in terms of sending data
Allows more users to use the same frequency
Separates frequencies into different channels in order to reduce interference
Reduced latency
Offers faster data rate transfer by using radio waves over the same bandwidth
Supports more data capacity
Low power consumption
Supports handover and roaming
Supports voice and Short Message Service (SMS) text messaging
Allows providers to transition without rebuilding their entire networks
Supports targets up to 350/kmh
Small coverage area in US
Requires a SIM card
Expensive if there is no existing framework
Needs additional antennas at network base stations

27. Futures Satellite WiFi WiMax LTE
Companies are launching new satellites to handle more users and give faster speeds
WiFi
In the future we may see a ac and/or ad.
802.11ac (theoretically) will support speeds from 600 Mbps to 1Gbps. It will utilize <6 GHz frequencies.
802.11ad (theoretically) will support speeds up to 2.5Gbps. It will utilize the 60 GHz frequency band
There is no definite documentation on how far the future standards could reach
WiMax
WiMax has an uncertain future. With Sprint looking to LTE for their future 4G+ data offerings, no major cellular carrier in the US will be using WiMax. Europe and Asia already favor LTE.
Private companies generating their own wireless networks are the most likely to keep WiMax viable.
LTE
LTE coverage is expanding quickly
Sprint is transitioning from WiMax to LTE
LTE-Advanced networks about two years away
Sprint, Verizon, and AT&T have all announced LTE-Advanced as the next generation
Advanced speeds can reach 1-gigabyte per second

28. Personal
802.11n
Clearly the best choice for a personal environment based on our criteria
Having wireless is basically just the price of the hardware on top of the already in place internet cost.
Linksys E $160
Provides high range for house/home
Enough speed for family requirements
Easy installation

29. Small Business
802.11n
Same thing as the personal setup. For a small business the only wireless capability they will need will come in the form of providing wireless access to their primary internet connection.
Anything else is over kill and most likely out of budget for a small business.
Linksys E $160
Provides high range for house/home
Enough speed for family requirements
