Cordless design – 2.4GHz and DECT

RTX Telecom has acquired in-depth knowledge of different components and chipsets, especially from National Semiconductor, and is thus able to design and develop DECT and 2.4GHz solutions very quickly. Profiles currently supplied by RTX include GAP, CAP, IAP and DPRS.

Unique selective performance RTX Telecom is your guarantee for getting a

DECT or 2.4GHz product with:

• unique performance

• very small form factor

• a competitive BOM

2.4GHz

On the North American market, a considerable number of wireless telephones are based on analogue technology, as opposed to DECT products, which require digital technology. RTX Telecom has therefore developed DECT 2.4GHz with frequency hopping specially for this market. This technology is used in digital products operating in the 2400-2483MHz frequency band (also known as the ISM - Industrial, Scientific and Medical - band). The RTX Telecom 2.4GHz platform is a low-cost solution based on the DECT GAP standard protocol, along with proven hardware and software. The platform uses 79 RF channels and is based on Fast Frequency hopping (up to 1700 hops/sec).

Immunity to interference

One of the advantages of RTX Telecom’s 2.4GHz technology is its high immunity to interference from sources such as microwave ovens. An example of a final PCB for 2.4 GHz, where the RF form factor can be as small as 400 mm2 AT&T dual handset cordless telephones engineered by RTX Telecom, based on 2.4GHz technology.
