Powerwave Technologies Inc. introduces three devices that push networks onward on the road to 4G technologies. These are an LTE picocell for indoor applications, an active array antenna and a remote radio Head with 65MHz of instantaneous bandwidth.

The LTE picocell for indoor applications offers form factor and signal power levels that are optimized for office buildings, shopping centers and indoor venues. It can support up to 100 active outdoor users and 32 active indoor users, and up to 1,000 registered users. It supports all 4G frequency bands in the 700MHz to 2.7GHz range and features a 2x2 MIMO antenna for additional capacity. It also features an optional concurrent dual-band 2.4GHz and 5.8GHz 802.11a/b/g/n Wi-Fi radio that makes it a single system for all carrier and enterprise wireless needs.

The second device is an active array antenna that combines the company's remote radio head and antenna technologies into a single integrated design with a 3dB-5dB link budget that increases a base station's coverage radius by 100 percent over non-integrated antennas. Its claims to cut power consumption by 40 percent in a design that has the same height, width and front windloading as conventional antennas, enabling like-for-like swapping of existing tower infrastructure.

The antenna contains all the subsystems necessary to deploy the complete 3G or 4G RF subsystem up the tower in frequency bands from 700MHz to 2.7GHz, including wideband world radio transceiver, power amplifier with advanced DPD and CFR algorithms, integrated filter and duplexer, LNA and cross-polarized antenna with the greatest gain per unit length. The antenna supports CDMA, WCDMA, HSPA+, WiMAX and LTE.

The third device is a remote radio head that offers 65MHz instantaneous bandwidth capability that eliminates the need to tune the product or deploy multiple radio heads to cover different frequency bands. This gives wireless operators the flexibility to deploy a single radio head and configure it via software for a variety of carrier configurations and technologies without having to physically revisit the cell site. Designed for 3G or 4G networks operating in 700MHz to 2,700MHz bands, the 65MHz RRH's integrated software-defined radio allows for simultaneous operation of independent protocols, providing seamless migration of legacy 3G networks to LTE. Its small and lightweight form factor coupled with a fiber fed structure enables easy installation on towers or rooftops, supporting an extensive combination of carrier configurations. It also offers remote management.

The 65MHz RRH provides wideband multiple-input multiple-output (MIMO) multimode capability with power levels ranging from 10W through 50W per transmit path in combinations of 2T2R, 2T4R and 4T4R. It is capable of supporting virtually endless combinations of HSDPA, EV-DO, WiMAX, and LTE air interfaces simultaneously.
