One downside of LTE-Advanced: It could make smartphones bigger and bulkier

Everyone who loves fast mobile data should be very excited for LTE-Advanced since it’s the next iteration of LTE technology that promises to deliver average downloads at 100Mbps or higher. But Technology Review has posted an interesting article that touches on one of the downsides of LTE-Advanced: It could make smartphones bulkier than what we’ve become used to over the past several years. Because LTE-Advanced relies upon multiple-input, multiple-output (MIMO) technology to deliver its high-end speeds, it requires multiple antennae that receive data signals from different spectrum bands to function optimally.

Dish Network signs LTE-Advanced chipset pact with Qualcomm

Dish Network signs LTE-Advanced chipset pact with Qualcomm

Dish Network Buys Qualcomm LTE-Advanced Chipsets

It’s still a bit early to get excited about the next generation of LTE, called “LTE-Advanced,” that carriers are planning to roll out in a couple of years at the earliest. But Dish Network wants to make sure it’s keeping up with the competition, which is why it has already locked in a deal with Qualcomm to develop LTE-Advanced chipsets for future devices, reports FierceWireless. Dish has a 40MHz chunk of satellite spectrum on the 2GHz band that it’s itching to use for terrestrial LTE-Advanced services if the Federal Communications Commission gives it permission to do so later this year. For the uninitiated, LTE-Advanced will represent a major upgrade over current LTE technologies, as the International Telecommunications Union has said that LTE-Advanced will deliver average download speeds up to 100Mbps (which, coincidentally, was its original requirement for a service to be defined as “4G” before the group caved to pressure from carriers and withdrew its position).

NTT DoCoMo, Samsung and four others create joint venture for LTE development

NTT DoCoMo, Samsung and four others create joint venture for LTE development

NTT DoCoMo, Samsung, Fujitsu, Fujitsu Semiconductor, NEC and Panasonic announced plans on Tuesday to establish a joint venture in which the firms hope to work together to create LTE and LTE Advanced products. The fabless JV will specifically focus on the development of “feature-rich, small-size, low-power-consumption semiconductor products equipped with modem functionality” for LTE and LTE Advanced networks. Products developed by the companies will be sold globally. NTT DoCoMo will invest $5.8 million in the joint venture but it is unclear how much of an ownership stake it will have, or how much the other five companies plan to invest. They hope to have the partnership fully established by March of next year. NTT DoCoMo’s press release follows after the break. More →

Sprint to roll out LTE-Advanced network by mid-2013

Sprint to roll out LTE-Advanced network by mid-2013

Speaking during the 4G World conference in Chicago on Tuesday, Sprint’s vice president of network development and engineering Iyad Tarazi confirmed that Sprint will begin to roll-out a 4G LTE-Advanced network in its 800MHz frequency spectrum by the middle of 2013. LTE-Advanced offers faster data throughput than the first generation of LTE, among other enhancements, and Tarazi explained that Sprint’s LTE-Advanced network should offer download speeds between 12-15Mbps. During its Strategy Update meeting in October, Sprint confirmed that it will begin to roll out its first 4G LTE network in mid-2012 with completion scheduled by the end of 2013. The initial LTE network will be deployed on Sprint’s 1900Mhz frequency spectrum and the first round of LTE devices will still route voice calls over its CDMA network. The first voice-over-LTE devices will arrive during the first quarter of 2013, Fierce Wireless said. Tarazi also noted that Sprint will offer at least a dozen LTE devices next year. More →

Clearwire announces plans to adopt 4G LTE – if it can find the money

Clearwire announces plans to adopt 4G LTE – if it can find the money

Clearwire on Wednesday announced its intent to adopt LTE across its network. The 4G wholesaler says it may add LTE Advanced-ready technology to its network that will provide up to 120Mbps download speeds according to network technology trials. ”Clearwire plans to raise the bar again for mobile broadband service in the United States,” said John Stanton, Clearwire’s Chairman and interim CEO, in a statement. “Our leadership in launching 4G services forced a major change in the competitive mobile data landscape. Now, we plan to bring our considerable spectrum portfolio to bear to deliver an LTE network capable of meeting the future demands of the market.” Clearwire confirmed that it does not intend to discontinue support for its 4G WiMAX network in the near term, and it will continue to build out its WiMAX network. The company did not put a timeline on the plans, however, saying that its entire LTE deployment strategy is “subject to additional funding.” Clearwire’s full press release follows below. More →

The 4G forgery

The 4G forgery

T-Mobile does not have a 4G network. Sprint, which first launched WiMAX in June of 2009, does not have a 4G network. Verizon Wireless will flip the switch on LTE later this year and when it does, it will not have a 4G network. AT&T is taking its time with LTE and it won’t fire anything up until next year. When it finally does, AT&T will not have a 4G network.

“4G”, as we now use the term here in the United States, is marketing speak. Carriers have devalued it to the point where it simply doesn’t make sense to fight it anymore… but I’m going to anyway. More →
