The mobile phone market is dominated by mostly reputable companies and even lower cost devices from Huawei are strictly controlled, providing a good level of quality, reliability, and customer support. The rugged device market has to fight with some counterfeit cases and very low cost devices that do not fulfill what they promise but these devices have hardly gained foothold in developed markets. The PTT accessory market on the other hand has a much bigger problem with counterfeit cases. Some end users are complaining about failure rates of 40 percent and higher, bad customer service, and high return shipping costs to mostly East Asia. To avoid this, companies have to put the same amount of focus on sourcing adequate PTT accessories as they do for mobile phones and PTT applications. Here are a few precautions companies can take to avoid significant amounts of communication downtime and administrative work to get devices exchanged.
A Crash Course in Bluetooth Security
Since wired devices are connected directly to the mobile device, it is hard to tamper with them unless someone gets very close to the user. Bluetooth devices use waves which can be picked up by anyone. It is important to ensure that anything being communicated through the Bluetooth device (not only voices but commands through button presses) are using secured channels that cannot be intercepted.
