Proxim’s pre-802.16 Tsunami MP.11 perfectly solves the requirements of metropolitan area networks, mobile hot-spot and cost-effective last mile access. We'll examine how the Proxim Tsunami MP.11 is truly a pre-802.16 product by discussing a methodology to migrate to the MP.16 from the MP.11, and comparing the features of the Tsunami MP.11 products to the 802.16-compliant Tsunami MP.16.

Tsunami MP.11 models 2454-R and 5054-R contain many similarities to Proxim’s planned 802.16-compliant Tsunami MP.16, which Proxim intends to use to obtain WiMAX certification. Smooth transitions to WiMAX will be possible because the Tsunami MP.11 channel plan is similar to that used by the Tsunami MP.16, and therefore the MP.11 and MP.16 may exist in the same wireless network by using the same channel planning methods that are used today to prevent Tsunami MP.11s from interfering with other MP.11s located in the same network.

Proxim Tsunami MP.11
Beyond simply co-existing, the MP.11 offers many of the same features which are important in metropolitan area networks, mobile hot-spots and last mile access. Like the much like the Tsunami MP.16’s 802.16 protocol, MP.11’s Wireless Outdoor Router Protocol (WORP) adapts to avoid collisions and maximizes data content with each transmission, and WORP’s dynamic data rate selection automatically compensates for temporary link degradation, maintaining robust connectivity and mitigating service calls. The following table more summarizes some of the other similarities between the Tsunami MP.11 and the Tsunami MP.16:

Feature	Tsunami MP.11	Tsunami MP.16
Signal Bandwidth	5, 10, or 20MHz	5 or 10MHz
Modulation	OFDM	OFDM
Frame Structure	WORP Polling	802.16 Polling
Dynamic Modulation	Yes	Yes
Per-SU MIR Packet Throttling	Yes	Yes
Transparent Bridging Mode	Yes	Yes
Routing Mode	Yes	Yes
Data Encryption	AES	3DES
DFS per ETSI EN 301 893	Yes	Yes
Uplink Power Control	No	Yes

While Proxim continues to add features to the MP.11 to make it even more competitive, Proxim is also applying significant development resources to maintain a leadership position in the development of the 802.16d-compliant Tsunami MP.16, partnering with Intel to develop a reference platform for other vendors interested to develop their own 802.16 products. This virtually ensures that Proxim is the first to market with Intel-based 802.16 products. Intel and Proxim will also work together to develop base stations based on the emerging 802.16e specification designed to enable broadband wireless portability. Portability will enable powerful new applications, and will be ideal for global service providers and carriers looking to introduce advanced data services.

The Tsunami MP.11 product perfectly solves the requirements of metropolitan area networks, mobile hot-spot and cost-effective last mile access. The Tsunami MP.11 can be deployed in networks today, and later co-exist with the Tsunami MP.16s as networks are transitioned to Tsunami MP.16.
