We observe that customers wants WHAT is the international standard value and what is value that Huawei device support ? 

Such questions really mater. As we know that mostly Huawei products are made according to International standards recognized by international body like ITU and IEEE etc but less references are available on support web and HedEx.

 I wish that we add International standard reference against every Technical specification of the product in separate column and better to add web link also.
