| Re: In another word said by L337  :The US will behind from the rest of the world, again. All your country belong to us. It seems our education system needs a bit of work, too. 
I wonder what their idea of "serious deployment" means? I'm not even sure if I would consider FiOS to be a serious deployment at the current rate it is being pushed out. Certainly DOCSIS 3.0 is eons away from being seriously deployed here in the US. At the rate things are going, Comcast may even decide to just skip DOCSIS 3.0 and concentrate their efforts into the next big technological advancement. I mean, they did skip over DOCSIS 2.0...seriously.
Hopefully the wireless world will move at a much faster pace when it comes to deployment and the introduction of new technologies. I suppose XOHM can be used as a benchmark. If in 3 years XOHM is still only available in Baltimore and certain parts of Maryland, my expectations will not be all that high for LTE deployment. If the definition of "serious deployment" means a select number of beta testers in Charlotte 5 years from now, we are doomed. | |

| Re: In another word I can certainly see verizon making the transition faster than AT&T. I seriously doubt that tmobile has any intention of rolling out LTE anytime soon. They are still working on deploying their 3g network to more than a handfull of large metro areas. They would need to operate that network Theoretically longer to ensure a return on investment, thus no hurry.
And yes I know they're part of the LTE group or whatever it's called. Merely stating not to hold your breath for tmobile LTE until LONG after the others. | |

| Re: In another word Verizon and Vodafone representatives have outright stated 2010 as their target to begin deployment in the United States (not on the rest of Vodafone's networks, though, the US will be first)- now, targets always shift, as countless examples show.
CDMA carriers are going to go to 4G before the GSM carriers- unfortunately for all its benefits, CDMA EV-DO is a dead end. Rev. B or C are unlikely to ever be taken up. On the other hand, 3G still has a ways to go in the US- some overseas carriers (I think Telstra in Australia is one of them) have much higher speeds, and HSPA+ allows this, so they can delay the total network replacement for a bit longer. CDMA carriers don't have this luxury. | |

| WiMAX is a niche? This is the message the LTE proponents want to send out. But it's LTE that is limited to the confines and control of the telcom industry. WiMAX is more open, has Intel and 50+ vendors behind it and is friendly to consumer electronics product makers.
It will probably be at least 5 years before LTE is broadly available and devices will mostly be limited to laptops and cellphones. WiMAX is controlled by IEEE, same as WiFi, which the consumer electronics makers are already tuned into. They only need to drop in a compliant WiMAX chipset and not have to deal with the carrier. For LTE, they'll have to work closely with carrier on their terms.
But it's true that WiMAX isn't 4G yet as the definition hasn't been ratified yet. MIMO antennas will probably be a requirement for the definition, which WiMAX will be capable of, but not all devices will be. | |

| Re: WiMAX is a niche? It's natural WiMAX will take it on the chin. Once again, Sprint is 1st to market with a "niche". Years ahead of LTE and, more adaptable. So, not only does it have a headstart, it will be more refined and upgraded over the years to come, just when LTE is learning to work. Having seen things go from the "lab" to "market", who are they kidding? Theory is one thing, reality is another. WiMAX is here now, deploying now. And meanwhile, LTE is back at the lab.... showing how fast it can go from one side of the room to the other...  | |

I believe they have a new version of HSDPA in the lab, NOT LTE and yes... the original HSDPA is out. AT&T has been the first in many things, the ONLY in many things, and has the same equivelant of other things that other carriers boast about. They usually have been very good with being the first or else keeping up with innovative technology and other carriers technology. (I guess the reason they are most expensive) | |

| Re: I wonder how ATT will utilize 700mhz spectrum AT&T will upgrade its existing HSDPA with the next version HSPA +. The upgrade to a 20 Mbps HSPA will be backward compatible with current HSPA device.
LTE and HSPA use different underlying technologies (OFDMA vs WCDMA) which does not allow them to operate in the same spectrum. This is one of the advantages WiMAX has. the next version of WiMAX 802.16m will match LTE's projected capabilities and be backward compatible with current 802.16e devices. I think devices will be out around the same time as LTE. So comparing LTE with WiMAX 802.16e is apples to oranges. WiMAX 802.16e to HSPA is the better comparison | |

| Re: I wonder how ATT will utilize 700mhz spectrum Their current version of HSPA does 7.2 Mbps on the downlink and it will be upgradeable to 20 Mbps with the next of HSPA, which I believe is called HSPA +. Upgradeable meaning within the same frequency bands that they currently offer their HSPA service. Is that what you're asking? Maybe I'm misreading you | |

| not surprising quote:
AT&T’s Hank Kafka, VP of Architecture, yesterday told attendees of the 4G Executive Summit that the company "has a lot of runway left with HSPA and HSPA-plus" and they're in no rush to upgrade their networks to LTE, theoretically capable of wireless broadband speeds up to 170Mbps.
Because they have barly upgraded to HSDPA. HSDPA coverage is a joke compared to Verizon and Sprint's coverage (% of network that is 3G). | |

1 edit | Compare wimax and HSPA, not wimax and LTE Let's be serious, wimax has at most demonstrated max thoroughput of 2-4 Mbps in mobile form. Yes, that's probably as fast or faster than current HSPA, but it will not be in the same category as LTE when it is deployed, from what I've seen of LTE. The US would benefit if we had a definitive mobile standard, therefore we could sell devices and phones without having to tie them to any one carrier. It's like CDMA, it's a stupid US proprietary technology that just acts as an inhibitor to innovation.
2-4 Mbps is not revolutionary, so I don't get why Wimax seems to be everyone's wireless networking dream come true... | |

@omcastbusiness.net | Re: Compare wimax and HSPA, not wimax and LTE I agree, but next gen Wimax 802.16(m) will have LTE like capabilities and should be available around the time LTE is widespread in 2012. And it will be backward compatible with current mobile WiMAX installations. | |

1 edit | said by mike12806 :Let's be serious, wimax has at most demonstrated max thoroughput of 2-4 Mbps in mobile form. That's the average throughput considering distance and obstructions. The devices are capable of 15Mbps or more and if you sat next to the tower, you maybe be able to get 15Mbps. Some early testers of Xohm have gotten 11-12Mbps.
Backhaul and spectrum will also be a bottleneck with nextgen rollouts than just the technology itself. ATT is talking up 20Mbps for HSPA but will they really provide enough backhaul to every site to avg 20Mbps for several users on the same site? Do they even have the spectrum for HSPA unless unless using 700mhz?
Sprint has about 100mhz spectrum per market for WiMAX. ATT has maybe 25Mhz in 700mhz and probably even less available in 800/1900 space. | |

| Re: Compare wimax and HSPA, not wimax and LTE Well said. According to a friend of mine at Sprint, backhaul was the main reason for the delay in its WiMAX rollout. 3G and 4G systems need towers that have fiber or microwave solutions for backhaul to meet their bandwidth demands. A lot of Sprint's WiMAX tower rely on multiple T1 lines that run 1.544 Mbit/s per line. This isn't a lot and it limits how many users they can give a good user experience to. Sprint spectrum advantage will allow it to do better than AT&T who has less spectrum and presumably the same backhaul concerns.
HSPA+ (20 Mbps) will operate in the same frequencies its current HSPA does. AT&T and other GSM carriers also have the option to refarm some of their 2G GSM spectrum for HSPA rollouts. Some GSM carriers I think in Thailand and Brazil have already done this. | |

| LTE Hello All,
This is Praveen Gupta, managing consultant, MobileStack (you wireless knowledge resource). I agree with Hank Kafka of AT&T. LTE will not be ready for next 2 years (for sure). The reason: LTE has adopted "distributed RNC" architecture and removed RNC (as used in UMTS architecture). This change, alone, requires testing of LTE in a large FOA to ensure that LTE can achieve full-mobility (in scalable manner) with distributed RNC. It may require design changes & fine-tuning based on FOA experience. All this will "delay" LTE readyness for commercial deployment and being "ready" for prime-time.
Thx. | |

@comcast.net | Wimax for (some of the) backhaul? Praveen-
Do you happen to know ATT's plans for utilizing WiMax for backhaul purposes? I was under the impression that would be one option where they needed it the most.
