LTE TDD Emerges as a Mobile Broadband Force
Mobile broadband traffic and subscriptions are booming, as small- and large-screen data-enabled devices such as smartphones, laptops, and tablet computers gain popularity worldwide as must-have consumer products. Growth in mobile broadband traffic exceeds 100 percent per year in many markets, including both developed and emerging economies. New mobile broadband markets are quickly opening up through allocation of unpaired frequency bands, giving rise to increased interest in a technology that can enable use of those bands: Long Term Evolution Time Division Duplex (LTE TDD).

While LTE Frequency Division Duplex (LTE FDD) global band allocations are well established and in some markets, have already been auctioned off many operators, most notably in Asian markets such as India and China, are now looking to LTE TDD as a means of offering much-coveted mobile broadband services using spectrum outside the LTE FDD allocations.

There is no question that LTE TDD is continuing to gather industry momentum, and that technology and service vendors within the mobile industry are well advised to examine the LTE TDD market carefully. Opportunities in LTE TDD are likely to exist in practically any part of the mobile value chain, from chipsets and software to network products, service platforms, and new devices. As the largest industry vendors are forcefully driving LTE TDD, opportunities in subcontracting of technology or services to OEMs or directly to network operators should be relatively plentiful over the next two to three years.

The challenges to LTE TDD's success are strongly linked to the challenges facing the LTE community, since LTE TDD shares 90 percent of its technical basis with LTE FDD. Probably the most important issue to be resolved is the industry-wide acceptance of a single standard for LTE voice. It is still likely, however, that LTE TDD will develop into a broadly successful mobile broadband standard in line with previous 3GPP standards. LTE TDD markets and technology are expected to reach maturity in 2012.

LTE TDD Emerges as a Mobile Broadband Force analyzes the technology and market factors that will influence LTE TDD deployments worldwide. It identifies the key drivers for LTE TDD, including the use of the technology as an evolutionary growth path for mobile WiMax. The report details the technology underpinnings of LTE TDD, including an analysis of spectrum availability and data rates, and it identifies the key strengths and weaknesses of LTE TDD compared with other mobile broadband options, including LTE FDD. It addresses market and revenue opportunities for network operators and technology suppliers, and it profiles and analyzes nine leading suppliers of LTE TDD products.

Sample research data from the report is shown in the excerpts below:
Table of Contents (4gltei1110_toc.pdf)
LTE comprises two standardized schemes for establishing multi-user upstream and downstream data connections on the physical radio link to the end user. LTE FDD employs widely separated and equal slices of radio spectrum to accommodate the uplink and downlink streams, while LTE TDD uses a single unpaired band to accommodate both uplink and downlink. In the excerpt below, the top section shows continuous downlink streams for downlink and uplink in FD, while the lower section shows seven possible asymmetric splits of uplink and downlink for TD.
