Overview / Main Features
The Huawei U120 is a basic 3G UMTS phone with Quad-Band GSM capabilities, based on a Qualcomm MSM6245 chipset. It has a candybar form-factor, a single 1.8 diagonal 262K 176x220 TFT display, a single 1.3MP camera module and features Bluetooth.
Overall - this phone is, at the time of writing, what has really become a mid-market mainstream phone with no particular standout features - in fact, Huawei calls this an entry-level 3G phone.
Mainstream users - based on feature set - marketing materials appear to allude to youth-market orientation. Or, per Huawei's press release: ""…a 3G handset optimized for music lovers on the move.".
Release / Availability
Per press release Feb, 2007. Based on Huawei's press releases their regional focus is based on their relationships with specific service providers, ""…such as Vodafone, Hutchison, Telefonica, SFR and PCCW….Huawei terminals have been widely used throughout the globe in regions such as Europe, Asia Pacific, Latin America and Africa."

For the purposes of this teardown analysis, we have assumed a lifetime production volume of 1.1M units.
As a reminder, teardown volume production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed volumes are different by an order of magnitude, minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis because of this.
ISuppli's Design Forecast Tool (DFT) and Market Shares
As part of iSuppli's Design Forecast Tool (DFT), we forecast handset shipments by major design feature and manufacture, as well as the number of design starts a manufacturer will have by feature set.
From our Design Forecast Tool (DFT), we estimate unit shipments of 116 million units of WCDMA handsets in the 2008 global market. We further estimate unit shipments of 301 million 1Mpx camera phones in the 2008 global market.

What Is Not Included in our Cost Analysis
The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.
Huawei's Relationships / Manufacturing
We do not track, as part of iSuppli research, Huawei's manufacturing and EMS relationships, however, based on their Chinese origins, we are assuming that Huawei are building in house and sourcing, where not otherwise noted domestically in China.
Country of Origin / Volume Assumptions
Based on markings, the unit was assembled in China. Furthermore, we have assumed that custom mechanicals (plastics, metals, etc.) were all domestically sourced in China.
Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as Bluetooth modules), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.
Remember also that labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. ""Auto" inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pincount of the device. This calculation is affected by country or region of origin as well.
Design for Manufacturing / Device Complexity
The Huawei U120 has a total component count (less box contents) of 652 components, of which 84 are mechanical in nature - this seems well within the norms for a phone with this type of feature set.
Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design.
Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.
The design revolves around a Qualcomm MSM6245 chipset (part of Qulacomm's Value Platform) - or basically a near turn-key solution from Qualcomm, as is often the case with phones based on a Qualcomm core baseband chip. This includes the MSM6245 baseband processor, the PM6650 power management chip (found in 90%+ of Qualcomm-based designs we see), and the Qualcomm RTR6275 RF Transceiver. In addition there are RF Micro Devices and Anadigics in the PAM slots for GSM and WCDMA respectively, and a Samsung NAND/SDRAM MCP in the memory slot.
Overall this is a fairly basic design of limited scope and cost.
