Description: 假设在一个ad hoc网络中,移动节点的发射功率PTx总是恒定的。要发送数据的移动节点总是先监听信道,测量接收到的信号功率X,其中X= I + N, I为接收到的干扰,N是噪声。移动节点只有在X<INThre时,才可以发射。式中,INThre为背景噪声门限。 在仿真中,我们规定每个移动节点的发射功率是常数,PTx = 1W;接收节点接收机的灵敏度Smin = -80 dBm;信号质量 min = 2 dB;系统的背景噪声门限INThre = 1.2e-10。

Description: 第二代EZRadioPRO系列无线收发器IA443X在240~960MHz频段内的最大输出功率达到了+20dBm,这意味着它的收发距离可远达2千米。与此相对应的是,它的主要竞争对手TI目前实现的最大输出功率是+12dBm。 目前市场产品上,我们是市场上第一家能做到如此大输出功率的公司。IA443X的主要目标应用市场是远程无线抄表、家庭安全和报警、无线PC外设、工业控制、玩具控制和远程汽车遥控等。-EZRadioPRO series of second-generation wireless transceiver IA443X at 240 ~ 960MHz frequency band has reached the maximum output power of+20 dBm, which means that it can be as far as two kilometers from the transceiver. In accord with this is that it' s main rival TI to achieve maximum output current power is+12 dBm. Products currently on the market, we are first in the market one can do such a large output power company. IA443X The main target application markets are remote wireless meter reading, home security and alarm, wireless PC peripherals, industrial controls, remote control toy car remote control, and so on.
