Sprint - Why WiMAX?

I was somewhat surprised when I heard that Sprint Nextel (S) was building a separate network based on WiMAX technology. This is not a replacement for its 3G cell phone system but in addition to it. Why would they do such a thing given the scale, complexity and cost? Are they doing this in the hope that if they build it, they (customers) will come?

So first of all, what is WiMAX and why is it significant?

Technically speaking, it is a 4G wireless broadband network that uses the mobile WiMAX (Worldwide Interoperability for Microwave Access) IEEE 802.16e-2005 technology standard.

Why is that good? Because you can get high-speed Internet access with it for devices ranging from phones to PCs and devices we haven't thought of yet. And in this case, WiMAX "high-speed" is significantly faster than typical Internet access via current mobile phone technology. It will be a real data network, not a data pipe bolted onto a telecommunications network.

What could this lead to in the future?

Initially, Sprint is rolling out the product in the areas where it has the strongest coverage which, like most other cell companies, is centered on urban/suburban clusters. This will be a boon for those users who don't want to pay for wires, cable or fiber into their homes or businesses. It will allow companies, large and small, to string together Wi-Fi hotspots without running network cables. It will allow mobile workers, iPhone owners and others who want to take advantage of Internet services to access it anywhere in the coverage area and at speeds that allow for the enjoyment of video and music. It has the potential to finally make Internet access on hand-held devices a "must have" feature.

Another huge potential market for WiMAX, however, is in the rural areas in the US and elsewhere. The Millicom Cellular (MICC) model comes to mind. Where it is unprofitable to wire the environment, strategic placement of wireless towers can lead to high rates of adoption of the service. Sprint could get a first mover advantage in many parts of the country that have had no major telecom or broadband service.

As expensive as this initiative is, the fact that there is no need to cover the last mile to consumers' homes or businesses with wire or fiber is a large cost savings advantage that the cable and phone companies don't have. And the fact that users can be completely mobile should be a compelling attraction.

Sprint is looking to pull in $5 billion in revenue from the network by 2011, which is about what they estimate it will cost to build the system. If there is any reality to that estimate, it implies a pretty quick move to the break-even point.

If this really takes off, what other companies will profit?

Sprint has announced that they will be working with Intel (INTC), who has been instrumental in developing the WiMAX specification and WiMAX chipsets for PCs. They will also be working with Motorola (MOT), who could use another good source of revenue, and Samsung, who already has deployed mobile WiMAX in Asia.

Sprint has entered into an agreement with Craig McCaw's Clearwire (CLWR), who is also building a WiMAX network. This will allow customers to roam across both company's WiMAX networks much like cell phone users do.

Today, Sprint announced that they have chosen Zyxel Communications of Taiwan as its primary vendor for equipment needed to bring broadband Internet into customers' homes and businesses. BloggingStocks had a nice little post on the topic and why it was a smart move.


So, after looking into this, it appears Sprint is not so crazy after all. Nevertheless, given the cost of the initiative and the less than stellar performance turned in by the company lately, it is clearly a risky, bold move on the part of Sprint management. They might just be betting the company on this. As a consumer, though, I hope they succeed.

Sprint is quite a bit better at researching new technology than deploying it. They are hedging this huge bet with an accellerating their roll out of CDMA Rev. A, which may be their parachute if Wimax doesn't take off like wildfire.

WiMax still has many question marks, some of which are potential deal breakers for a truly "mobile" experience.
My experience with Sprint cellular service a couple of years ago would seem to bear out your first point - we ended up switching to Verizon. As to your last point, time will tell.

1. Sprints new WIMAX network (based on 2.5Ghz spectrum) is not a 4G network. Marketing spin. The industry has defined 4G totally differently and will be able to deliver bandwidth levels over 60Mbps.
2. Sprints and any other 2.5Ghz based system will be severally limited in rural markets becuase of the foliage/Canopy issues. Darn leaves absorb signal and do not reflect.
3. Most WiMAX systems deployed today are Fixed systems and not the new Mobile (802.16e). These fixed nets work very nicely in Urban markets (T-1 replacement) where one has good line of site or can use structures to reflect (OFDMA) signals.
4. When SPrint/Clearwire/Intel and others adopt the new 700Mhz spectrum and wrap it in WiMAX features they will have what I call a true Broadband (Mobile/Fixed) wireless distribution system addressing all Urban and Rural markets.
5. Intel will eventually update their Centrino line to handle only 2 radios: 700Mhz based WiMAX systems and the new 802.11n (dual 2.4 &5Ghz)WiFi products. We'd then have a combination of WiMAX and WiFi Mesh systems delivering most all Broadband data to fixed and mobile systems.

Whoever wins the Nationwdie License for 700Mhz will set the direction in the industry for last mile Broadband-PERIOD.
The rest of the market will be FTTPremise.

Brazil - in a bubble or on a roll?

A couple of years ago, no one recognized the real estate bubble even though it was under everyone's nose. Now, analysts and bloggers are seeing bubbles everywhere they look. One of them, they say is in Brazil whose Bovespa stock market index has doubled in the last 12 months. Does the bubble accusation hold water? I don't think so and here are 7 reasons why Brazil is by no means a bubble economy: Exports have held up over the past year thanks to demand from China for Brazil's soya exports and iron ore. This was helped by the the Brazilian government's drive to improve trade links with Asia and Africa. Export diversification, spurred by a more active trade policy and increased focus on "south-south" trade under current president Lula, helped mitigate the decline in demand from OECD (Organization for Economic Co-operation and Development) countries A "sensible" economic framework has been in place since the 1990's. This has included inflation

This is a quick post to announce that we have published Thursday's Trend Leaders, Swing Signals and Trend Busters at Alert HQ . All are based on daily data. Today we have the following: 72 Swing Signals -- A couple of days ago we had 35 signals, today we have twice as many. Happily, we now have 65 BUY signals, a mere 4 SELL Signals plus 3 Strong BUYs. Whoo-hoo! 56 Trend Leaders , all in strong up-trends according to Aroon, MACD and DMI. There are 18 new stocks that made today's list and 60 that fell off Tuesday's list. 48 Trend Busters of which 5 are BUY signals and 43 are SELL signals The view from Alert HQ -- Talk about mixed signals. If you look at our Swing Signals list you would think the market was in the middle of a big bounce. BUY signals are swamping the SELL signals and we even have a few Strong BUYs. Yes, there's a good sprinkling of tech stocks and tech ETFs but the distribution is pretty broad-based with a good number of different sectors represented, eve

Unlock Stock Market Profits - Key #1

This is the first in an ongoing series of articles where I discuss what I feel are keys to successful investing. It is based on a post that provides a summary of the ten keys that individual investors should use to identify profitable stock trades. ( Click here to read the original post ) There are two basic steps to investing. First, you need to find stocks that seem to have some potential. Then you have to determine whether these stocks are actually good investments. There are many stocks that at first glance look interesting, but further research reveals that there are too many negatives to warrant taking a position. This first post in the series starts at the beginning: getting good investment ideas. Key #1: If something special is happening to a stock, it will be reflected in some kind of unusual activity in the markets. As individual investors, we will never be the first to know; however, unusual activity can be an early sign that allows us to follow the Wall Street professional
