Why Sprint’s Commitment to 4G WiMax Worries Me

By  |  8 Comments

On its own, I commend Sprint for being the first 4G network in the U.S. by debuting its WiMax network and its EVO 4G smartphone long before rival Verizon Wireless had even unveiled its own 4G network based on the competing LTE network. However, when the carrier says that it’s committed to WiMax despite looking at potentially even adopting LTE, that really worries me as Sprint’s network could be the most nightmarishly fragmented system. Whereas the rumor before was that Sprint may try to supplant its 4G WiMax network with the 4G LTE protocol, Sprint CEO Dan Hesse says that “every option” for the carrier is centered around WiMax. Now, it seems that LTE may supplement WiMax, rather than replace it.

In fact, most recently, the company had talked about its Network Vision strategy and is seriously considering adoption of LTE–in addition to WiMax–moving forward for 4G. The decision of that debate won’t happen until later this year and is dependent upon a number of factors, but Sprint isn’t shy to say that it is looking at alternatives to WiMax, which it is delivering to customers via a partnership with Clearwire.

The carrier is also, according to recent speculations, looking at acquiring its next largest rival, T-Mobile USA, which operates a 3G GSM network. T-Mobile as a GSM provider is operating a 3G network based on HSPA technology. It also uses a faster evolution of HSPA, called HSPA+, which it is marketing as 4G in the States due to the protocol’s fast speeds that rival LTE and WiMax speeds.

Currently, Sprint’s Now Network already encompasses a number of different network protocols. It had inherited the iDEN network through its Nextel acquisition–Sprint is winding down the iDEN network soon. For 2G speeds, the carrier is operating a 1X network and it is using CDMA/EV-DO for 3G speeds. 4G is delivered on Sprint’s network via WiMax. If the rumored T-Mobile acquisition is true, Sprint will add GSM, EDGE, HSPA/HSPA+ technologies to its network. Also, if the LTE adoption really does happen, Sprint will also adopt LTE technology.

For geeks navigating through the various cellular and mobile broadband technology is difficult enough, but consumers who need to figure out what smartphone to get in the future may be confused by all these rival and competing technologies all found on the Now Network. Sprint will have to explain why its GSM/HSPA+ smartphone–acquired through a T-Mobile acquisition when and if that happens–would be capable of world roaming while its CDMA phones wouldn’t. It will have to explain why, perhaps, LTE smartphones are faster than WiMax and why it has competing 4G phones. Perhaps, it may also have to explain why its T-Mobile phones won’t be able to roam on AT&T’s network because T-Mobile already has a somewhat odd network configuration where upstream and downstream data are already handled on two separate frequencies, unlike AT&T’s, and that none of the 3G/4G frequencies are compatible with AT&T’s. That’s a lot of education, and a lot of headache!

    I believe Sprint want to give customers options like when you use your cable company.Dont you get to choose different packaged with your cable company!! This all means different prices depends on the customers needs it is that sample!!

      Well that is totally untrue. because most places that have a cable company have only once choice, and that is through that cable company. With cell phones you can in most cases choose from different carriers. Yes i can choose what package i want, but i am also at the mercy of what packages that company offers. The problem is simple to explain. When your the ONLY carrier in town you have no choices. Sprint has to be worried about people jumping ship to Verizon At&t T-mobile and others. Most people want more speed, and unless Sprint gets on the bandwagon, they will lose.

        I dont understand with RCN you can pick your internet speed that goes with most cable provider !! you get 10mbps or you can go up to 20mbps!!!For real Verizon is very expensive and att network sucks!!!I believe Sprint still have a chance!!!

    Perhaps Sprint will upgrade T-Mobile network to Wimax and slowly upgrade the US network to CDMA. Sprints wimax deploy is much further along and T-mobile has barely gotten started with 4G. The other possibliity is that Sprint will work with Quallcom to enable their dual mode CDMA chip.

    I have been a Verizon customer for years……. I SWITCHED to Sprint, and it was the right move.
    I have the same quality at a much lower price. I do have the EVO, and i must say, that phone is simply awesome……. A friend of mine works for Verizon…… he simply could not beleive the price comparison, he was tempted to become a Sprint customer…… even with his employee discount, he was paying more!!!!
