Long Term Evolution (LTE) is considered a 4G network technology. According to the GSMA, the trade group that promotes the GSM family of technologies, LTE is the next step from 3G/WCDMA & HSPA for many already on the GSM technology curve. Interestingly, though, a number of carriers across the world on the CDMA technology path have opted to switch to LTE for their 4G network upgrades. According to the GSMA, LTE is designed to be backwards-compatible with GSM and HSPA, and incorporates Multiple In Multiple Out (MIMO) technology in combination with Orthogonal Frequency Division Multiple Access (OFDMA) in the downlink and Single Carrier FDMA in the uplink to provide high levels of spectral efficiency. LTE can support channel bandwidths from 1.4 MHz to 20 MHz and both FDD and TDD operation. Commercial LTE service was first launched in December 2009 in Scandinavia by TeliaSonera. In 2010, carriers in the U.S. and Japan both released commercial LTE services. In the United States, MetroPCS offers LTE service in the AWS spectrum band, while Verizon Wireless offers LTE service in the 700 MHz spectrum band. Verizon said its LTE network, which it brands as a 4G service, provides average download speeds of 5-12 Mbps. AT&T Mobility is planning to launch LTE service in the United States in 2011, and Clearwire is testing LTE service in the TDD and FDD configurations. Sprint Nextel also is keeping open the possibility of launching LTE service. LTE-Advanced is the next step up in the evolution of LTE. According to the GSMA, LTE-Advanced “extends the technological principles behind LTE into a further step change in data rates. Incorporating higher order MIMO (4x4 and beyond) and allowing multiple carriers to be bonded together into a single stream, target peak data rates of 1 Gbps have been set.”

Cellular gears up to take on proprietary tech in the IoT: Explaining LTE Cat M, Cat 1 and Cat 0

Players such as Sigfox, Ingenu and the LoRa Alliance are rushing to meet those demands with low power wide area network (LPWAN) technologies, taking advantage of a head start as standards for cellular-based IoT offerings are finalized. As those cellular technologies begin to come to market, though, the two sides will battle to provide connectivity for everything from autonomous cars to industrial components to sensors in agricultural fields.

Cellular wraps its arms around the Internet of Things

Given all the attention on the Internet of Things (IoT), we decided to take  a closer look  at what wireless operators are looking to deploy when it comes to low power wide area networking (LPWAN) technologies.

DoCoMo CTO tries to debunk myths about 5G

With all the talk about 5G and the Internet of Things (IoT), things can get pretty confusing. Seeking to dispel some of the most pervasive myths about 5G, NTT DoCoMo CTO Seizo Onoe presented a keynote at the IEEE International Conference on Communications in Kuala Lumpur, Malaysia, on Wednesday.

Lowenstein's View: What should cellular, pay TV and broadband services cost?

A familiar refrain among consumers is that cellular, pay TV, and broadband are overpriced. But if you take a look at the cost of providing some of these services, plot them against demand and usage patterns, and consider some of the unique aspects of the North America market and geography, a different picture emerges. So here's my take, in terms of what looks reasonable from the perspective of the consumer, and service providers' requirement to operate a viable business.

Bouygues Telecom and Huawei achieve 1 Gbps 4G speeds using 4-band CA

Bouygues Telecom said it achieved speeds of more than 1 Gbps in tests on its 4G network with Huawei, becoming the latest operator in Europe to join what some have dubbed the "Gigabit LTE" club at least in terms of trials.

T-Mobile: We'll start to use incentive auction spectrum 'at the end of 2017'

Some industry analysts have speculated that it may take several years before carriers can begin to deploy services on the 600 MHz airwaves that the FCC will put up for auction in the coming weeks. But T-Mobile executives think they may be able to begin to leverage that spectrum as early as 2017.

Vodacom CEO prioritises spectrum for South African mobile data

Vodacom CEO Shameel Joosub said additional spectrum is essential to matching demand for mobile data services in South Africa, which he noted is falling behind in terms of fixed broadband rollout and access.

EE spends $29M on Avanti satellite capacity as part of 4G coverage push
