WiMax is more energy efficient vs Cellular for Mobile Broadband

Fire;

Interesting article, however ABI isn't some "independent" research firm. They have a stake in WiMax deployment so I would take anything they say with"a grain of salt". Also who knows if WiMax will ever get off the ground because both UMTS and EVDO still have solid migration paths and the wireless companies are not going to rip out all that equipment to replace it with something new and as yet unproven.

 

true but this still sounds interesting.

 

It greatly depends on the specific maker of the radios and semiconductors used in them. There are some companies that have more advanced 'guts' using femtotechnology (as opposed to nanotech or picotech). It is much more expensive, but also way more efficient at a given transmit power.

 

WiMax dowloads are also Faster than EV-DO

 

And your point to the topic at hand, aside from a thinly veiled stab at CDMA...which is somewhat ironic since it is a CDMA carrier advancing the general use of WiMax.

 

Isn't that the objective? to improve upon the previous tech?:biggrin:

yes i belive so.

 

WIMax is Not CDMA.
WiMax is WiFI but
w/ a Much Longer Range.
WiMax was anticipated to Compete
w/ DSL and Cable.

 

WiMax is also the 4G Route
of some GSM Carriers "wirles".
Sprint Knows CDMA EV-DO will
loose to WCDMA/gsm.

 

Some GSM Carriers already Deployed WiMax.

 

If you want to get technical WiMax is OFDM, and Mobile WiMax is OFDM-A. But that is picking nits.

 

I am quite aware of the international GSM carriers that have deployed WiMax, such as Ikatel Mali (affiliate of France Telecom). My point was that, here in the states (which is the focus of most threads here), Sprint (a CDMA carrier) has recognized the advantages to the OFDM-A over the air interface and capabilities versus their native CDMA/EVDO RAN network for the future of their business (4G).

GSM carriers in the US (ATT, for example) are currently leaning towards WCDMA with HSPA.

Bear in mind, Mobile WiMax is by definition a cellular deployment when deploying a large scale multi-site network with nomadic roaming and interoperable capabilities.

 

WiMax is most certainly NOT WiFi. Go read a bit and educate yourself before you attempt to assert yourself with incorrect data. WiFi is a standard, as is WiMax. They operate very differently. To the lay person, I can see where one would group them as they can provide similar service to your data device....but if you really want to be correct (and why wouldn't we) WiFi and WiMax are as different by definition of their standards as, say TDM and ATM or SONET.

 

From what I've read, the Sprint version of WiMAX will initially do 2-4Mbps up and down. A tower may be capable of 4-6 miles depending on terrain.

Sounds like Sprint plans combo WiMAX/EVDO cards under the same account for about $55/month.

What I'm not clear on is if it will be truely mobile, where you can switch towers while in a car or train. Doesn't appear so, which is why Sprint will still need EVDO. Any WiMAX heads know how mobile WiMAX works?

Sounds like Sprint is focusing on population centers in US while Clearwire is focusing on mostly rural areas. It's expected they will both roam on each other.

 

Sprint WiMAX spending ekes higher

I know that DC and Chicago are currently under way as test beds for the two vendors.

 

HeHeHeHeHeHeHe
WiMax --- Wi from WiFI
Max for Maximum Distance.
The Whole Idea is
WiFi for Outdoors, though Not Necessarily
the same as the Indoor G or B version whatever.
And Certainly Not CDMA.

I repeat WiMax is WiFi for Outdoors.
Is WiFi version B the same as WiFi Version G?

 

Yikes.

WiMax (Worldwide Interoperability for Microwave Access)

WiMax is described as wifi on steroids for simplicity. It makes the goal of the technology easy to understand for the average person. This is an unfortuante comparison as the two are about as similar as night and day.

 

Mobile WiMax, 802.16e, will have true mobility with base station handovers. You can expect reasonable high speed hand offs, like a train or fast moving car.

 

I'm just trying to Simplify Carry On,
I Should Rephrase the Analogy Question.

Is Indoor Sports the Same as Outdoor Sports?
Or is Indoor Web Access the Same as Outdoor Web Access?
Both are Sports and Both are Web Access.

WiMax Purpose is Web Access Outdoors
(if you Don't want to Call it WiFi for Outdoors),
it's Technology is Not CDMA but
is Faster than EV-DO.

 

I'm curious why you are so fixated on the outdoors. WiMax is currently used almost exclusively indoors at the moment.

The purpose of WiMax according to their own trade group is as a "last mile" broadband wireless access (BWA) alternative to cable modem service, telephone company Digital Subscriber Line (DSL) or T1/E1 service.

Using your analogy, Wi-Fi would have to be the indoor alternative to cable modem service, DSL, and T1 lines. As Wi-Fi clearly is no alternative to any of those, the analogy doesn't hold true or even make sense.

here is the info on the two from VOIP-news on both:

FeaturesWiFi vs. WiMax
(Post a Comment)WiFi and WiMax are competing wireless broadband technologies that are considered useful for VoIP. What are the pros and cons?
Hunter Holcombe on May 8th, 2006

It's no secret that wireless Internet access is growing at a furious pace in urban and suburban America, not to mention the rest of the world. Not only are residences and businesses steadily shifting towards wireless networks for ease of access and cost savings, but free wireless hotspots are popping up all over as commercial venues like cafes, hotels and even restaurants realize that wireless Internet access is becoming a fundamental customer requirement. In fact, it is almost requisite that service-oriented businesses have wireless available for their customers if they are going to compete.

Municipalities are even getting involved, with cities like San Francisco and Philadelphia investing in large-scale wireless networks that will potentially blanket the entire city, providing free wireless Internet access to all residents and visitors and allowing them to surf the Internet from such formerly implausible locations as parks, the bus, or even the beach.

The basic standard for this technology is WiFi. WiFi is primarily used to create a Local Area Network (LAN), which allows users within the network to connect wirelessly. The commonest use is primarily in Internet connectivity, but WiFi is also used for closed-circuit business networking and for connecting consumer electronics, such as TVs and DVD players. WiFi makes connecting to the Internet within a home or business cheap and easy, and it also allows commercial and service venues to provide wireless access to customers and the greater public, within a relatively small service area.

But while WiFi technology has proved largely successful in providing cheap wireless Internet service within close proximity to the WiFi access point, a new technology, WiMax, could expand the potential of wireless penetration and connection quality. Because of the similarity in name, it is easy to assume that WiMax is simply a more refined and more powerful form of WiFi, and one that will render WiFi irrelevant in the near future. This is partly true – WiMax does provide wireless reception over significantly greater distances, and at higher broadband levels. But the technology behind WiMax is significantly different from WiFi, as well as more costly, and most analysts agree that WiFi will continue to be the standard in the near future.

WiFi was created in Norway in 1991, and was originally designed for commercial cash register systems. Today, its provides wireless broadband access to any user with wireless connectivity technology, or wireless adapter cards, within a small range. Typically, a WiFi signal has a maximum range of 150 feet indoors and 300 feet outdoors.

WiMax serves several functions in wireless connectivity, but it was largely created to provide “last-mile” broadband connection to homes and businesses. Instead of using fixed lines like cable or telephone line to bring Internet access into a building, WiMax uses transmitters, like cell-phone towers, to carry its signal. WiMax technology does not require line-of-sight to the user, so several subscribers can connect to a tower, even if it is blocked by trees or other buildings. This makes WiMax particularly useful and cost-effective for rural homes and other locations set in a geography that would make laying a traditional hardwire difficult and expensive.

WiMax has a much greater range than WiFi, although interpretations of this range vary. While engineers have stated that WiMax could have a range of up to 30 miles, field tests have resulted in a range radius of between four and eight miles. Still, this represents a range far greater than the few hundred foot radius of WiFi.

WiMax also has some benefits over WiFi in terms of connection quality. When multiple users are connected to a WiFi access point, they are effectively in constant battle for connection, and users can experience varying levels of broadband width. WiMax technology, however, secures each user with a constant allotment of broadband access. Built into the WiMax technology is an algorithm that establishes a limit to the number of users per WiMax access point. When a WiMax tower is nearing its maximum broadband capacity, it automatically redirects additional users to another WiMax access point.

But WiMax is still in its infancy, and will need a significant boost in support and infrastructure before it gains any traction in the wireless market. WiFi, on the other hand, has already saturated a significant percentage of the wireless market, and it has proved both easy to use and cheap. While businesses with large physical space might want to move to WiMax to avoid buying the many repeater access points required with WiFi, it will be several years before WiMax becomes cheap enough to enter the residential and small commercial market.

In short, WiMax technology promises a future of more powerful and more accessible wireless Internet access. For the meantime, however, WiFi will be the mainstay.
