As mobility skyrockets, every device can get a smoothest internet connectivity with a Wireless LAN (WLAN) – whether there is a need to run a power-hungry CAD application at 150-Mbps speeds, or only 11 Mbps is required for sending an e-mail. Users can access Internet from WLAN hotspots in restaurants, commercial complexes and schools with portable devices such as laptops, tablets and PDAs.

Interested in designing WLAN? Mentioned below are some high-performance and cost-effective WLAN reference designs along with complete documentation including Bill of materials (BOM), schematics and user guides:-

Low-cost WLAN Design:

This reference design is a complete high performance RF front-end solution designed to meet the WLAN IEEE 802.11b/g standard in a small PCB form-factor. Using the MAX2830 RF transceiver eliminates the need for external SAW filters, a RF switch, and a PA. Only a RF filter, RF balun, and a small number of passive components are required to form a complete 11b/g WLAN RF front-end solution. Using the MAX2830 RF transceiver, the design is capable of accommodating full range of 802.11g OFDM data rates and 802.11b QPSK data rates. This solution offers high performance, small size, and low BOM cost. More on this Reference Design

WLAN Access Point with Security: 

RD_P1023WLAN_BD

Here is a reference design that supports applications of Wi-Fi Router, DMS (Digital Media Server), NAS with RAID, or Office in BOX, etc. The design is based on the MPC8377E PowerQUICC Pro processor. The design features integrated hardware acceleration for wireless security, MiniPCI or MiniPCI Express based interfaces for 802.11N radio modules, gigabit Ethernet LAN and WAN interfaces, USB 2.0 host/device interface and support for dual-concurrent MIMO operation. The design comes equipped with schematics, Gerber files, reference software, Bill Of Material (BOM) which can help original equipment manufacturers (OEMs) and original design manufacturers (ODMs) accelerate the development process and speed time-to-market for their real product. More on this Reference Design 

Compact RF Wireless Module: 

This reference design is a cost-effective and small-footprint (1.61″ by 1.02″) wireless radio system that can be designed into any number of monitoring and control applications to enable wireless control. It is available in both the 868 MHz and 915 MHz radio frequency bands. The Module can be easily mounted on a two-layer PCB with minimal external connections. This document discusses its specifications, lists schematics and software commands, and provides a procedure for quickly getting started with development. More on this Reference Design
