Dynamic Spectrum Management (DSM) in a nutshell: Dynamic Spectrum Management (DSM) in a nutshell Static Spectrum Management (SSM)
Based on region-based fixed spectral masks designed under the assumption of worst-case Xtalk interference
Dynamic Spectrum Management (DSM)
Transmit PSD’s are adapted to actual and time-varying Xtalk interference in order to optimize rate/reach performance
DSM levels of coordination
level 0: no DSM, hence SSM
level 1: Xtalk avoidance by means of single-user power allocation (centralized or distributed implementation)
level 2: Xtalk avoidance by means of multi-user power allocation (centralized implementation required)
level 3: Xtalk cancellation (upstream) and pre-compensation (downstream) by means of multi-user transmission (also called “vectoring” or MIMO = multiple-input multiple-output)

IEEE 802.16a: Fixed Wireless Access technologies under 10GHz: 2.4 & 5.8 GHz (both unlicensed) and 2.5 (MMDS) & 3.5 GHz (both licensed)
IEEE 802.16d (mid 04): provides additional capabilities such as antenna beam forming, OFDM sub-channelling
IEEE 802.16e: will add mobility to 802.16d in the future (on-going for end 04)

Cingular/SBC FastForward: Cingular/SBC FastForward A cradle to hold and recharge a wireless phone
When the Cingular Wireless phone is "cradled," calls to the wireless phone are forwarded to a designated landline phone
Cingular customers with a FastForward device can get unlimited incoming wireless calls (minutes) forwarded to their landline phone in the local calling area — without the minutes counting against their monthly wireless calling plan
Service is $3 per month plus the cost of the device ($40) but free to customers who receive a single bill for Cingular wireless and landline services.
