Technical Consulting and Contract
Design Capabilities
We are typically tasked with
two types projects.
1.Custom designs of networks, waveforms, and transceivers
for specialty applications.
2. Standards based transceiver architecture and system designs.
Our areas of expertise include the following
areas.

proprietary), GSM, IS-95, WCDMA, IS-54, ZigBee,
and WLAN, OFDM DSL, 802.11 a/b/g/n, Bluetooth, FM, FM/RDS |
| Modulations |
Spread spectrum
(DSSS, freq.
hopping), GFSK/GMSK, OFDM, QAM, FSK, PSK family, MIMO techniques |
| Multiple access protocols |
