Response from Netro engineer on TDMA

I thought the those who followed up on our earlier discussion of TDMA (and those
who think it is outdated technology, might like to read this.
This is a response from an RF engineer at Netro.
"Thanks for your interest in Netro and its products.
CDMA has been used mostly for voice on cellular networks, operates in the
800MHz and 1.9GHz (PCS) bands, and uses a spread spectrum technique that
codes each digital packet and allows multiple calls to be placed on one channel,
boosting caller capacity 20 to 35 times that of the analog network.
Netro's AirStar family transmits voice, IP and Frame Relay services to small and
mid-sized enterprise (SME), supports licensed frequencies at 10, 26 and 39 GHz.
Netro's patented CellMAC(tm), or media access control layer, coupled with the
product's TDMA and ATM foundation, enables the delivery of voice and data
traffic dynamically , on a packet-by-packet basis.
This increases spectrum usage and decreases equipment costs at the hub location.
AirStar uses TDMA to interleave multiple digital signals onto a single high-speed
channel. ATM allows the transport of multiple services with a guaranteed QoS.
For more information, please contact me directly.
