Enterprise WiMAX

WiMAX has been created with the consumer market in mind and with its standards targeting the telco wireless (cellular-like) infrastructure. However, WiMAX is definitely much more than that. This WG explores how WiMAX can be used for the enterprise.

Rizwan Abbas commented on ni putu wahyuni's blog post Uplink Throughput Problem

"What system it is TDD or FDD? If TDD then, please check the Symbol Ratio in UL and DL? Also can you please check in a better radio coverage that what CINR / RSSI values makes the modulation to 16 QAM."

Rizwan Abbas commented on Abhijeet kumar's blog post Which one is better for modulation scheme (2T4R 0r 4T8R in wimax)

"In addition to gain in Uplink the 4T8R configuration is ideal for Beam forming in the Downlink. So effectively the Downlink Modulation with 4T8R will be improved depending on the BF Gain provided by the equipment."
