WiMax and LTE:

In major metropolitan areas in the U.S., WiMax should available late in 2008. Sprint will make its commercial WiMAX debut in Baltimore in September. WiMax supports peak data speeds of about 20 MBPS, but, as with most broadband technologies, that bandwidth will be shared amongst users. On average, a user will see data rates between 1 MBPS and 4 MBPS.

Most major wireless carriers are skipping WiMax, planning instead to build out networks using a similar technology called Long Term Evolution (LTE), a successor to current cellular technology. WiMax has a head start on LTE, which won't be ready until 2010. These two technologies are referred to as 4G networks (Current state of the art mobile phone technology for accessing the Internet is called 3G). If mobile broadband service is important to you, these products will be very attractive. Unlike rivals GSM and CDMA, both 4G networks are based on "Orthogonal Frequency Division Multiplexing" (OFDM), also sometimes referred to as "discrete multi-tone modulation". Since both LTE and WiMax are based on similar technology, a unified standard is possible in theory, and discussions are ongoing. Motorola has said 85% of the technology and work for WiMax equipment will be reused in its designs for LTE equipment.

WiMAX and LTE can deliver large amounts of bandwidth operating at the low power levels necessary for mobile devices. Another advantage of WiMax/LTE is its ability to communicate out of line-of-sight (unlike conventional WiFi), and to communicate into large buildings, in theory making dropped calls, typical of today's cell phones, a thing of the past. A company called MobiTV will utilize the WiMAX network for the broadcast of TV, including HDTV. VoIP (telephone service) has already been deployed on WiMAX networks in other parts of the world.

Satellite HDTV:

While HDTV local channels are more available on cable than satellite, DirecTV and the Dish Network each offer more national HDTV channels. DirecTV offers about 60 national HDTV channels and the Dish Network has about 50 HDTV channels. DirecTV and EchoStar plan additional satellites to offer at least 150 national HD channels, as well as local stations in HDTV.

"Satellite's going to be constrained not so much by how many channels they can carry than by how many they can get," Bob Scherman, Satellite Business News.

By 2010, it is projected that 60% of TV receivers will use a Satellite signal, up from 15% in 2002.

Summary:

Median DSL speed in the U.S. is 768 KBPS.
Median Internet speed over Cable broadband is about 4.5 MBPS.
WildBlue service is approximately 500 KBPS.
WiMax service will be between 1 MBPS and 4 MBPS.
ViaSat-1 service (2011) will be about 2 MBPS.

HDTV service is currently more fully served by the satellite TV companies like DirectV and Dish Network. New systems being implemented by Verizon, or perhaps a thorough retooling by local cable TV operators will offer the best competition.

The supply of HDTV and Broadband service in the U.S. is currently fragmented from the satellite industry. Both may be available from local retailers, but a unified system is lacking. This compares poorly to Europe and EutelSat, which will launch Ka-Sat in 2010 (Ka-Sat is very similar to ViaSat-1, discussed above), and install this satellite in a satellite "neighborhood", so that a single system will receive both the TV signals from their HotBird satellite system, and receive high performance broadband from Ka-Sat. This is unfortunate for U.S. consumers.

Currently, over 90% of customers of broadband services utilize either cable broadband or DSL. However, new worthy competition is entering the fray, and it will be difficult for those services to maintain their market share.
