WIRELESS BLUETOOTH FOR MOTORCYCLE SAFETY HELMETS
Objective
To test real functional range for Bluetooth motorcycle intercoms in both an in-town atmosphere as well as a rural setting and accessibility their capacity to reconnect after being out of array. Examination is not designed to determine bike to bike range in all conditions but it ought to represent the two most common problems when riding with a
best bluetooth motorcycle helmet .
Conditions
In-town - Test was done along Hwy 70 East in New Bern North Carolina. All intercom designs were checked at complete battery fee.
Rural Environment - Test was performed down a straight dirt roadway about 1/2 mile from the closest residence and several miles from red light or businesses. Test was line of sight as there were no corners for 0.8 miles. There was however a radio station tower concerning 1 mile away (which we learned after the examination) and we were 8 miles from a Marine Corps Air Station (Cherry Point) which no doubt puts off some radar and other signals. Weather condition was clear and about 72 degrees. All intercom versions were examined at full battery cost.
Bluetooth Bike Intercom Array Test Procedure
In-town Environment Bluetooth Motorbike Intercom Range Examination - Each test was done with one non-moving headset in the open at 3-4 feet high beside the straight access road. Distance was called out every 0.1 miles on the odometer and sound was tape-recorded to verify high quality and repeatability. There is one stop light about 0.25 miles away from the beginning factor in each direction.
Rural Environment Bluetooth Motorbike Intercom Range Examination - Each examination was performed with 2 non-moving headsets. We attempted to obtain audio recordings of all headsets back to back at a certain distance however having 4 Bluetooth headsets powered up in close distance endangered the signal of SOME of the units so rather we evaluated one headset at a time at 0.1 mi, 0.2 mi, 0.4 mi and so on.
Test Samples (Product Versions).
HBC200 by UClear (first launch firmware).
Interphone F5 - by Cellular Line.
Scala Rider G9 by Cardo (initial launch firmware V 1.2).
SMH10 by Sena Bluetooth (V 4.0 firmware).
UClear HBC200.
Declared Intercom Array - "as much as 700m/ 0.43 miles" with 2 headsets.
This is great in some pertains to but instead compared to waiting for 20 secs of silence before silencing it does so virtually promptly after the person on the various other headset stops talking. UClear cases their usage of Super Team Modern technology and also Multi-Hop attribute will certainly allow "up to 10 or more" HBC200 headsets can be connected. We only had 2 headsets available for testing so we might not confirm if this would certainly extend the variety or not.
In-town Instructions 1 - The interaction was clear at 0.1 miles and also operating at 0.2 miles but then went entirely silent when passing the intersection with a red light prior to 0.3 miles.
In-town Direction 2 - The link was clearer at 0.2 miles here or even 0.4 miles appeared to be usable. At 0.5 miles the connection was lost. The HBC200 headset units did not automatically reconnect after the return journey as well as the intercom discussion had actually to be re-initiated by pushing the headset button. While the UClear's audio features are leading notch this failure to reconnect could be the HBC200's most significant flaw. Uclear confirmed that the discussion does not immediately reboot which this was not customer related. We hope their very first firmware update will resolve it.
At 0.2 miles the speech was clear and there was no static yet we had concerns with the VOX reducing off syllables. At 0.4 miles the intercom was not usable.
Interphone F5.
Declared Intercom Array - "approximately 1300m or 0.8 miles" with 2 headsets prolonging as much as "2400m or 1.49 miles" with 6 headsets spaced flawlessly apart.
Notes - The Interphone F5 does an excellent task of muting the speakers when the various other headset's microphones are not in usage. Nonetheless, during speech there is some slight static sound (scratchiness) behind-the-scenes of the voice. This immediately vanishes when the various other person quits talking.
In-town Instructions 1 - The Interphone F5 was clear at 0.1 miles and also functional at 0.2 miles. It transferred a great deal of sound around the red light and also although it was aiming to send and also interact at 0.4 miles the speech was completely muddled. At 0.5 miles it alerted using voice prompt that intercom was separated. Coming back it automatically re-connected the discussion as well as gave a voice punctual specifying "intercom linked" when we went to 0.1 miles apart.
In-town Direction 2 - The F5 intercom conversation was distorted as we underwent the intersection at 0.25 miles and a lot of interference which sounded like a synthesizer playing music was heard/ taped. This sound was not listened to in the headset on the bike since nobody was talking to them at that time. However, the intercom stayed linked with the crossway and also speech was apprehensible at 0.4 miles. At 0.5 miles the intercom again disconnected and also the connection was re-established when we returned to within 0.1 miles of the other headset.
We established one headset at 0.15 miles as well as ran the very same test as above. The quit light crossway still rushed the signal as well as caused a whole lot of digitized songs noise so that it was mostly pointless on the various other side of the crossway however we were able to go to 0.6 miles as well as transform around without experiencing the "intercom unavailable" message and the relay effect seemed to aid quality even more than harm it.
At 0.9 miles it alerted by means of speech that the intercom link was lost. After returning we were informed at 0.4 miles that the intercom was linked as well as speech was instantly clear.
Sena SMH10.
Declared Intercom Variety - "approximately 900 meters/ 0.56 miles".
Notes - While the SMH10 has a VOX feature readily available when there is a songs resource we did not make use of songs during this test as well as instead picked the "open mic" intercom telephone call. Generally once began the mic is constantly warm. The SMH10 for that reason transfers everything and while linked there is a small hum even when nobody is chatting. The tiniest engine or wind sound would certainly drown it out however it is a sign that you are linked. As you get further apart the hum has the tendency to turn right into digitized music fixed.
In-town Instructions 1 - The Sena SMH10 was clear at 0.1 miles and looked to a digitized fixed at 0.2 miles and also forward.
In-town Instructions 2 - The Sena was clear at 0.1 respectable at 0.2 miles however became odd as we went via the stoplight at 0.3 miles. It remained linked and also was usable at 0.4 miles but at 0.5 miles there was no audio signal sent. When returning the SMH10 units were still linked and also useful at 0.4 miles apart.
Rural Environment Array Test Sena SMH10 - The discussion was clear at 0.1 miles and also primarily functional at 0.2 miles nonetheless there was most definitely fixed impacting the conversation. At 0.3 miles there was no signal transferred. Comparable to UClear HBC200 the Sena SMH10 worked also or better around compared to in the country atmosphere.
Cardo Scala Cyclist G9.
Asserted Intercom Array - "Approximately 1 mile".
Notes - The Scala Motorcyclist G9 does a great job of isolating and getting rid of the undesirable sound/ static and distortion from the signal. While the SMH10 has the tendency to allow excessive with the Scala Biker G9 and UClear HBC200 may isolate way too much, enabling only ideal speech through and silencing every little thing else. No question some will certainly appreciate this but some compromise of static for added useful array would be great. (In-town test was carried out without raising the antennae while the rural examination was executed with the antennae elevated.
In-town Direction 1 - We had great hopes that the Scala G9 would certainly be able to get over the disturbance yet it was not the instance. The Scala Biker G9 was clear at 0.1 miles and totally peaceful at 0.2 miles.
In-town Instructions 2 - The Scala Cyclist G9 was clear at 0.1 miles as well as totally peaceful at 0.2 miles.
Rural Atmosphere Range Examination Scala Cyclist G9 - Just Like the in -town condition the Scala Cyclist G9 was clear at 0.1 miles and afterwards peaceful (no voice signal transferred) at 0.2 miles. The headset did not inform us that "Biker An inaccessible" till we got to 0.9 miles (and rounded the corner out of line of website). Upon return the headset never ever informed us that we were again linked however at 0.1 miles the mic was energetic and also the discussion once more can be listened to. Cardo's claim of damaging the 1 mile beerier is technically real due to the fact that they were still "connected" but additionally totally incorrect since they are not usable at 1.0 miles also with line of website and low disturbance.
Conclusions.
In the city environment you are most likely to be riding closer with each other as well as at slower rates so the fairly short variety should not really hamper the use of these systems for connecting bike to bike. In big teams where you might have several automobiles in between and possibly get stuck at one light while the other bike continues the disturbance noise and also shorter range will definitely trigger some annoyance. The Sena SMH10 and also Interphone F5 appeared to have the most effective usable variety and also capability to remain linked even when disturbance stopped them from communicating clearly. They did nevertheless, cause/ permit the most altered noise/ static to find with while the UClear HBC 200 and Scala G9 protected against that from entering the headset.
Winner Bluetooth Headset Array Test - Interphone F5 - If bike to bike variety is high on your concerns for Bluetooth headset showcases you should seriously consider the Interphone F5. In the rural setting nothing else comes close and also adding even more headsets to the team only extends the variety. Obviously, you could pick among the others and afterwards attach it to a GMRS radio or acquire a ChatterBox X1 Slim to obtain more range however we doubt you will have any complaints with the F5.
