調査テーマ
前回の調査では、驚きの通信可能距離69m（理論値超え）を計測し、様々な施策への利用が期待できる結果となりました。
この通信可能距離で、例えば、車にBeacon端末を付けて街を走ることで、道行く人々へ通知することも可能なはずです。
ここまで考えてふと疑問が浮かびました。
「移動するものに端末を付けたとしてスピードの有無は関係あるのだろうか？時速何kmまでいけるのだろう？」
これも事実を明らかにする必要がありそうです。

Investigation Theme
From our last investigation, we've measured a surprising potential transmission distance of 69 m (which exceeded theoretical value), a result that we hope can have application to various policies. This potential transmission distance can, for example, can be used in a car beacon and be used to send notifications to people walking down a street.
Now that we think about it, a question has come to mind.
"Will speed be a factor when we put this instrument in a moving object? Between which kilometers per hour will this work?"
We will probably have to figure that out.

Theme of Investigation
In the previous investigation, we marked a surprising transmissible distance of 69m (beyond theoretical value), which might be possible to apply for several policies.
With this transmissible distance, for example, a car driving on a street with Beacon terminal might enable the notification to passengers-by.
So, a question came up to my mind.
If we equip the terminal to moving thing, does it matter if they are speeding or not? How many km/h will be available maximum?
We need to find the result of this issue.

Theme of operation test
During the previous operation test, the communication range of iBeacon was proved to be amazing distance of up to 69 m (exceeded the theoretical range), and it offered the expectation to various applications.
For example with this communication range, it may be capable of notify to walking people by installing a iBeacon terminal to a car.
When I have been thinking about this, there has come up one doubt.
"If iBeacon is installed to the mobile object, is there any relation with the velocity?" "Up to what velocity will it be possible?"
This doubt also needs to be clarified.

Start of investigation.
It's afternoon during the weekend and clear.
We've assembled at a road where we have previously confirmed has little traffic.
We've carefully installed the beacon onto the car.
We've installed it right beside the driver's seat in the inside part. If anything happens, the beacon will not fall out of the car. We also opened the windows fully in order to increase the likelihood of successful transmission.
We've also put in someone who will be taking in the reception in another car.
Now everything's ready and and we should be successful with our experiment!
We drove the car with the beacon on the opposite lane.
Both cars are driven at a set speed and we are basing this experiment on the relative velocity of the cars as they pass each other.

Operation Test
In the afternoon of a holiday.
We gathered near a road we previously research with low traffic.
Install the iBeacon to a car with great care.
The iBeacon was installed inside of the car at drivers seat side.
Therefore, it is not dropped off from the car even something is happened.
Because it may affect the receiver sensitivity, the window is opened without any question.
Person in charge of receiving terminal rides to the other car.
This is all set for the operation test. The operation test will definitely successful.
The car installed with the iBeacon is moved to the opposite lane immediately.
Try to conduct the operation test by passing two cars at steady speed each other.

さて、結果は？
反応がない。相対速度時速120キロだとさすがに反応しないようです。残念。
気を取り直して時速50キロでも試しましょう。
受信できてないですね。
続けて時速40キロも試します。

First we did the experiment at 60 km/h.
The relative velocity will be 120 km/h.
If we are able to get a reception, then this can also have application on freeways.
We've kept it at 60 km/h. The car with the beacon came to us on the opposite lane.
So, what is the result?
No response. With the relative velocity being 120 km/h, of course there would be no response, which is a shame.
We regrouped and tried again this time going at 50 km/h. But we didn't get any reception.
We then tried it at 40 km/h, but even that didn't produce any results.
Our excitement steadily dropped with the speed.
Even an attempt at 30 km/h was a bust.

We started the experiment with 60 km/h.
In relative velocity it will be 120 km/h.
If the reception were possible, the usage could apply for highway driving.
Keeping 60 km/h, the Beacon terminal-equipped car is approaching from the opposite lane.
The result was: no reactions. I'm afraid the relative velocity of 120 km/h doesn't work.
Let's go on to further experimentation: how about 50 km/h? No reception.
How about 40 km/h? No reception.
The less velocity the less our hope.
30 km/h didn't work, too.

Start the operation test at 60 KPH at first.
The relative speed becomes 120 KPH.
If it is successive, the operation test at expressway is brought to be perspective.
The receiving terminal does not react. It does not react to the iBeacon signal at the relative speed of 120 KPH as expected. What a pity!
Pulling ourselves, and try at the speed of 50 KPH.
Cannot receive the iBeacon signal.
Out tension goes down as the speed goes down.
No at all at 40 KPH.
Not yet at 30 KPH.

相対時速60キロでの受信が不可能だと分かりましたので、高速道路で走行中の利用は難しそうですね。
とはいえ、まだ一般道での利用は可能な速度域です。
これ以上速度が下がると、さすがに他の車の通行に影響が出ます。
そこで受信担当者が車を降り、ビーコン端末装着車を待ち受けることにしました。
電波状態を考慮して、遮蔽物の少ない橋の上で待機。
ビーコン端末を助手席側に取り付け直し、いざ時速50キロで走行。
はい、ちょっと覚悟してましたが、やっぱりダメでした。引き続き時速40キロで挑戦です。

Now that we knew that there would be no reception at 60 km/h relative velocity, it will probably be difficult to get this thing to work on a highway.
However, there is a chance that it could work at speeds that are set at local streets. If we decrease the speed even more, the influence of passing vehicles will indeed increase. So we decided to take the person in charge of the reception out of his vehicle and have him wait outside for the car with the beacon.
Taking electric magnetic waves into consideration, we've decided to have him wait on a bridge where there are relatively few obstructions.
We put the beacon on the passenger side seat, and drove the car at 50 km/h.
Well, we did kind of prepare for the worst, but indeed it did not work. Next we tried it at 40 km/h.

We got to know that the reception in relative velocity of 60 km/h is impossible, so our usage wouldn't apply for driving on highways.
However, this velocity still applies for local streets.
If the velocity will be lower, it probably disturb the traffic of cars.
So the reception staff got off the car, waiting for Beacon terminal-equipped car.
The staff was waiting on the bridge with no barriers.
Beacon terminal was re-equipped in passenger seat's side, driving a car with 50 km/h.
We had no expectation, no, it didn't come true. We'll go on further to 40 km/h.

It seems it is difficult to use the iBeacon at express way as it cannot receive the signal at the relative speed of 120 KPH.
Though it is still within the speed range on the public road.
The further reduction of speed may cause adverse effect to the other running cars.
Therefore, we decided that the person with receiving terminal gets off from the car and wait for the car installed with iBeacon on the sidewalk.
We chose the waiting point on a bridge with consideration of signal reception obstruction.
We change the installation position of the iBeacon to the assistant driver's seat and drive the car at 50 KPH.
Well, it is failed again though we make up our mind to be. Challenge at the speed of 40 KPH again.

なぜ片方だけが受信できたのか？受信端末依存などもあるのでしょうか
若干の謎は残しつつも、成功したことは大きな収穫です。

40 km/h: reception impossible
Or no reception impossible at all when moving?
Finally, we tried 30 km/h, which we didn't expect any good news.
Wow, one receiver did receive!
The first success in 30 km/h!
Why the one terminal received, depending on reception terminals?
We've got some issues to be clarified, but this success is really surprising and amazing.
If we consider the usage below this velocity, a slow-driving cars, for example advertising trucks, motorized bicycle, etc. may send the signal.

The signal can not be recognized under 40 km/h.
It is assumed that this function can not work during moving.
As a precaution, a test at 30 km/h is also conducted without too much expectations.
Nobody smell the success of this test.
However, one of them worked !
It is the first time to success in receiving singal at km/h.
The reason for why only one received signal may be depending on the reciving device.
Anyway, it is a big harvest, although some mysteries remains.
It is possible to use this application on the vehicle with low speed such like advertising track,or motorbike.
