今年Computex当中,就有一区是专门针对物联网的专区,物联网的核心包括两部份,其一是传感器,另一个就是低功耗网络,而腾马Toumaz公司虽然是外商,不过主要研发团队是在台湾。腾马的无线技术最早是针对无线的医护传感器材市场所设计,从医护市场的成功经验转到一般消费性市场。

腾马的无线技术并非采用市场上的标准技术,亦即不是蓝牙或是ZiGbee等市场标准,而是采取专属的传输标准,传输的频带选在800~900MHz之间。由于低功耗无线技术的应用市场并不是针对高带宽,降低功耗、稳定与穿透率才是该技术的重点,800~900MHz频带不仅没有2.4GHz容易受到干扰的问题,并且天线尺寸也在可接受的范围,腾马的无线技术的传输速度也能满足如心跳、呼吸侦测所需的更新速度。

腾马的技术功耗仅3mA,相较蓝牙或是ZiGbee的10~15mA明显更低,在同样的运用情境下,腾马的无线技术能够提供相较ZiGbee等标准规范长达3倍的电池寿命,并且可藉由调整各终端的信号发射时间间隔,在传输范围理论上可连接无限的接收端。此外,腾马的无线解决方案在接收端并不需要ROM,而是透过主机端将系统同步到接收端芯片整合的RAM中,整个接收端模块仅使用15个IC组件,拥有较低的成本。

腾马表示,低功耗无线技术的应用领域,除了在如物联网、家庭自动化以及智能电网以外,也有许多新兴应用,如高价值农作物生长与保护监测。而今年的拜访的客户,也有一些微妙的应用,像是把腾马的无线技术用在一些深入人体的微妙器材中,进行远距遥控,至于是用在哪种领域,还真是难以启齿阿。

Computex 2011: Toumaz Showcases Low Power Consumption Wireless Technology

In this year's Computex, there is a specialized section for IOT (Internet Of Things). The key to IOT are two parts, one is sensor, and the other is low power-consumption network. Tourmaz, an UK company with R&D centres in UK and Taiwan, started their R&D in wireless technology from the field of medical monitoring, and now migrating the success experience to consumer market.

Tourmaz's wireless technology is not based on standardized wireless standards, nor market standards like Bluetooth or ZigBee, but their own proprietary standard, which transmit on 800~900MHz band. In most market applications for low power wireless technology, bandwidth is not as important as power consumption, connection reliability and ability to transmit through obstacles. The 800~900MHz band offers less interference than 2.4GHz, reasonable antenna size and sufficient bandwidth for data refresh rate required by medical monitoring.

In terms of energy consumption, Tourmaz's wireless technology require only 3mA, which is significantly lower than the 10~15mA power required by Bluetooth or ZigBee. Under the same application scenario, Tourmaz's wireless solution offers three times longer battery life compare to standards such as ZigBee. And by adjusting each end-points signal transmission interval, it is possible in theory, to connect to unlimited receiver within the signal coverage. Besides, Tourmaz's wireless solution synchronizes system code from central computer to RAM module integrated inside the receiver chipset, therefore the receiver does not require a ROM, and would requires only 15 IC component for the whole receiver module, hence lower manufacturing cost.

According to Tourmaz, apart from IOT, home automation and smart electricity grid, there are some new applications such growth and protection monitoring for high-value crops. And there were some odd enquiries made by this year's visitors to showroom. For instance the application of Tourmaz wireless solution to remote control some peculiar instrument that would penetrate deep into human body. As what exact field of application it is, it's rather embarrassing and better left unsaid.
