2.4GHz RF and Bluetooth Smart solutions for remote controls
Consumers have never had so much choice in terms of digital content and services, or such a challenging time accessing it. The Nordic ultra-low power (ULP) wireless technology already installed in millions of wireless PC peripherals worldwide is the solution. In products such as connected (Internet-enabled) TVs, for example, it supports RF remote controls with advanced navigation features such as touchpads, touchscreens, and QWERTY keyboards, without suffering interference from bright light sources (e.g. LED TVs) that affect IR.
Nordic offers the following reference designs to speed up your product development:

Nordic Semiconductor's ULP wireless range provides attractive solutions for any consumer electronics device that would benefit from a wireless link by offering:
The nRF51 Series are flash-based SoCs, as such they represent the most flexible solution available. A key feature of the nRF51 Series and their associated software architecture and S-Series SoftDevices is the possibility for Over-The-Air Device Firmware Update (OTA-DFU). See fig. 1. This allows firmware updates to be issued and downloaded to products in the field via the cloud. This enables OEMs to fix bugs and introduce new features to products that are already out in the marketplace. This brings added security and flexibility to product development when using the nRF51 Series SoCs.
If you have very specific application demands and no requirements for interoperability through standards such as Bluetooth Smart or ANT, then proprietary protocols sometimes provide the best alternative. When this is the case, 2.4 GHz proprietary solutions often offer the greatest flexibility, best power consumption, and lowest Bill of Material. Nordic provide the Gazell proprietary protocol to serve these applications.
Gazell is a freely distributed, simple to use, low-power protocol developed for use with Human Interface Devices (HID) peripherals. Gazell is designed for systems that have asymmetrical power consumption requirements where a central hub may have relatively relaxed power demand requirements while communicating with a number of peripheral devices that have much more stringent power efficiency needs. HID applications include mouse, keyboard, remote controls, presenters, and drawing tablets.
Bluetooth Smart is an exciting technology that is becoming a standard feature in PC's and mobile devices. Bluetooth Smart Ready devices form the hub of our personal area networks, these include smartphones and tablets as well as dedicated hub products. Bluetooth Smart devices are the peripheral sensors that typically capture data and relay data to and from the hubs. Bluetooth Smart profiles are already available for a range of different applications.

The nRF51 Series is Nordic's latest generation of ULP wireless System on Chip IC's that again sets the benchmark in this field. The nRF51 Series is based on the 32 bit ARM Cortex-M0 CPU and Nordic's leading multiprotocol radio and supports Bluetooth Smart, ANT, and 2.4GHz proprietary solutions. Across the range pin-compatibility allows for drop-in replacement of device types where application requirements differ with no requirement for redesign of circuit layout. The innovative software architecture ensures an absolute separation between application code and protocol stacks, and enables you to maintain one code base for products using different wireless technologies.
The nRF24L Series SoCs are the most common solution for wireless PC peripherals in the market today. Based on an enhanced 8051 CPU and Nordic's radio technology, the nRF24L Series SoCs represent an extremely popular, cost-effective, and proven choice for PC peripheral development.
