The Problem Many factors contribute to the limitations of wireless systems of which the most important arguably are frequency bandwidth and frequency efficiency. Though efficiency may be increased by higher modulation rates, more sensitive receivers, and more accurate bit error detection/correction methods, wireless telecommunications systems are built around the frequency bandwidth limitations that are set by governing authorities. Consequently, once bandwidth is used up in an area, no other system utilizing the same frequency bands can coexist and hence data speeds are limited.
The Solution ET Industries’ antenna systems solve these problems by increasing the available bandwidth for an area. To achieve this, our systems have been designed to produce up to 96 sectors around the base station by spatially optimizing frequency usage. By using interference rejection technology, site interference between sectors is kept to a minimum. The ability to reuse frequency bands in the same area facilitates a substantial increase in the throughput.
