The philosophy of PicoCast Solution
 Market [Leading the Paradigm]
 The paradigm shift is due to a change in needs of user convenience.
 Start in a niche market and move to a huge paradigm shifting market.
 Consumer ⇒ Customer ⇒ User⇒ Owner (of Personal Space)
 Personal Computer ⇒ Internet ⇒ Smartphone ⇒ Personal Cloud ⇒ Personal Network
(Wireless Owner oriented Network)
 Business [Needs oriented Affordable and Powerful]
 Realize marketable wireless personalized products with proven solution that are easily available.
 Use the strategy of burning wet firewood with a single matchstick.

The GOSPEL chip already contains all the information necessary for the growth of the network.
Designed to be interference-free from the start: Hybrid Orthogonality (Time, Waveform, Code)
The entire communication network serves as a single point for all subscribers.
All network elements are represented by one 64-bit identification code system (PS-ID).
(Synch rank, personal ID, things, instruments, organization, accounts, service, currency, accessories, and etc.)

PicoCast; wireless network that grows like a cell
Ara, Phone Block; 2013
Block
Approach

A smartphone made of prefabricated modules, just as a PC is made of prefabricated modules.
- In 2013, Google announced the promotion of Project Ara, a prefabricated smartphone acquired from Motorola.
- In September 2016, withdrew from the Ara Project due to a failure in the smartphone free strategy using white spectrum.

※ It is more difficult to connect divided blocks seamlessly than to make individual blocks.
※ Promoting the wearable smartphones is only possible when there is no radio interference between the decentralized devices.




TSMA-type PicoCast devices do not interfere even if multiple modules are used at the same time.
Even if the frequencies are different from each other, they are never transmitted when the adjacent modules receive them.
Transmission and reception modes are determined in units of containers
(except for two-piece containers and control boxes)

PicoCast-SDR is based on using two RF modules simultaneously.

In the case of a 2-piece container, weak propagation is fired during the Control Box period in a very important receive mode.

Two bands of PicoCast-SDR may support (A, A), (B, B), and (A, B) mixed protocols.

Sinusoidal Orthogonal Waveform
 Conditions for orthogonal waveforms to create a modulated signal with good frequency spectrum characteristics
The smoother the signal connection at the boundary of the symbol, the less spurious and the narrower the bandwidth.
In order for orthogonal waveforms to be smoothly connected, the signal amplitude and slope at the boundary line must be the same.
As the cosine waveform of SOW satisfies this condition, spurious is reduced to 1/100 level compared to OFDM.
SOWbinary has the same frequency spectrum as MSK.
SOW is capable of transmitting M-ary signals, and it is possible to use sine waveforms in addition to cosine waveforms.
SOW Sine waveforms do not have the same slope at the boundary line, but if the frequency of the waveform increases, the slope difference is negligible.

Orthogonal between each other orders
Orthogonal between each other orders
In-phase SOW: order=1,2,3,4,5,6
Quadrature SOW: order=1,2,3,4,5,6
 As the order increases, the power spectrum of in-phase SOW and quadrature
SOW becomes the same.
 Waveforms with different orders in each group are orthogonal to each other.
 Orthogonal relationship is not guaranteed between even and odd orders
from different groups.
 Nevertheless, the use of sampling methods at symbol boundaries allows for
individual demodulation of in-phase and quadrature waveforms.

Correlation with different phase & order
Even-orders are perfectly
orthogonal regardless of phase.
Odd-orders are perfectly

Swift to its close ebbs out life's little day Earth's joys grow dim, its glories pass away
Change and decay in all around I see O Thou who changest not, abide with me

Heaven's morning breaks, and earth's vain shadows flee In life, in death, o Lord, abide with me
Abide with me, abide with me, abide with me

Swift to its close ebbs out life's little day Earth's joys grow dim, its glories pass away
Change and decay in all around I see O Thou who changest not, abide with me
I fear no foe, with Thee at hand to bless Ills have no weight, and tears no bitterness
Where is death's sting? Where, grave, thy victory? I triumph still, if Thou abide with me
Hold Thou Thy cross before my closing eyes Shine through the gloom and point me to the skies
Heaven's morning breaks, and earth's vain shadows flee In life, in death, o Lord, abide with me
Abide with me, abide with me
