Although Nokia Corp. is no longer the leader in smartphones and feature phones, it still has abilities to design state-of-the-art devices. For example, the recently launched Nokia 105 phone is not only available for $20, but it is sold at a profit, according to a new teardown.
With its ultra-low-cost handset (ULCH) model designated as the 105, Nokia has shown how is it possible to make a profit from a $20 handset: by sticking to a limited set of features and employing a highly integrated design. The Nokia 105 yields a margin of less than 30%, strictly based on hardware and manufacturing costs and retail pricing, according to a physical dissection of the cellphone conducted by IHS iSuppli.
The Nokia 105 carries a bill of materials (BOM) of $13.50. When the manufacturing cost is added in, the cost rises to $14.20. At a suggested retail price of $20.00 – a new low for a ULCH cellphone – this gives the 105 an implied hardware and manufacturing margin of 29%, which suggests modest a profit margin for the Nokia 105.
The table below presents a summary of the IHS teardown of the Nokia 105. This teardown assessment is preliminary in nature, accounts only for hardware and manufacturing costs, and does not include additional expenses such as software, licensing, royalties or other expenditures.
“About eight years ago, the IHS dissected the iconic Nokia 1110 cellphone, a hugely popular device that defined the ULCH segment and had very similar features as the new 105. We determined that the 1110’s BOM was nearly three times larger than the 105’s – even when accounting for the black-and-white display used on the old model. Therein lies the 105’s secret: By keeping features the same for nearly a decade, the Nokia 105 can integrate nearly all system functions into a single chip, dramatically reducing the cost to produce a cellphone. The 105 allows Nokia to participate in the ULCH market targeting specific regions and consumers,” said Wing Lam, principal analyst for IHS.
Targeting the ultra-low-end allows Nokia to approach the 105’s design in a manner that is the polar opposite of the strategy commonly used in the mid to high-end cellphone market, i.e., adding features to products each year, while maintaining the same BOM costs and pricing.
The 105 extends Nokia’s 1100 line, targeting emerging markets including Africa, India, and Latin America. The phone supports long talk and standby times, which are valuable in regions with poor power grids or frequent shortages of electricity. The features of the phone are very simple, with just talk and text capabilities.
“While much attention has been lavished on smartphones, the market for simple handsets remains very important to Nokia. Non-smartphones, including ULCH cellphones like the 105, accounted for 90% of Nokia's shipments in 2012,” said Wayne Lam, senior analyst for wireless communications at IHS.
In terms of design, the 105 owes its low costs to a single, highly integrated chip: Intel Corp.’s PMB7900. The PMB7900 combines baseband and the RF transceiver enabling GSM/GPRS functions. With so much functionality packed into a single device, the 105 contains only three integrated circuits in total – compared to six for the 1110.
“This is the fruit of nearly a decade’s worth of integration. By riding Moore’s law and holding the line on features, Nokia has gone from six discrete integrated circuits (ICs) to just one core device plus two other ICs,” said Mr. Wing Lam.
The other two ICs in the 105 are the SKY77580 transmit module from Skyworks as well as a NOR flash device from Micron. Collectively, these three ICs dominate the baseband/RF transceiver/memory subsystem and, when combined with supporting passive components, carry a cost of $5.25, representing 39% of the 105’s total BOM.
Despite support for color, the 105’s display carries a cost of just $2.25, or 17% of the total BOM of the phone.
Nokia has kept this cost to a minimum by employing a TFT-LCD display with a low resolution of 128 by 128. This display technology is very mature and is available in high volume. In the individual 105 model examined by IHS, the display was made by China’s Tianma Microelectronics. But there are multiple suppliers of this component, with competition among them further contributing to keeping the price down.
