PMP 430

 

PMP 430 SM

 

 

If the Configuration Source on a PMP 430 AP’s Configuration > General

 

used with

 

MIR configured

 

 

tab is set to Authentication Server or Authentication Server + SM,

 

Prizm or

 

by Prizm to

 

 

SMs will receive their MIR settings from Prizm (or BAM). The resulting SM

 

BAM

 

greater than max

 

 

MIR may be greater than the keyed throughput of the SM. For context, the

 

 

 

sustained MIR

 

 

PMP 430 SM is available keyed to have a maximum throughput of 4, 10,

 

 

 

data rate (12257)

 

 

20 or 40 Mbps.

 

 

 

 

 

 

If the SM receives a MIR setting from Prizm that is greater than the keyed

 

 

 

 

 

 

bandwidth, the SM will cap the MIR using this formula:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(desired uplink MIR * SM aggregate capped rate) / desired aggregate rate

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(desired downlink MIR * SM aggregate capped rate) / desired aggregate rate

 

 

 

 

 

 

 

 

Note: Desired aggregate rate is the sum of the desired uplink rate and desired

 

 

 

 

 

 

downlink rate

 

 

 

 

 

 

For example, if a PMP 430 4 Mbps SM with a max MIR cap of 4000

 

 

 

 

 

 

receives a MIR setting from Prizm that is greater than 4000 kbps, it will

 

 

 

 

 

 

cap the downlink MIR and the uplink MIR to equal a max of 4000 kbps.

 

 

 

 

 

 

Below is an example with Prizm settings of 10000 kbps uplink MIR and

 

 

 

 

 

 

7000 downlink MIR sent to a 4 Mbps SM that is capped at 4000 kbps max

 

 

 

 

 

 

MIR:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Uplink calculation:

(10000 * 4000) / (7000 + 10000) = 2352 kbps

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Downlink calculation:

(7000 *4000) / (7000 + 10000) = 1648 kbps

 

 

 

 

 

 

 

Thus the Uplink MIR of 2352 + Downlink MIR of 1648 = 4000 kbps

 

 

 

 

 

 

In this example, the PMP 430 AP sessions page will display a SM uplink

 

 

 

 

 

 

and downlink MIR SMCAP as shown below.

For reference, the max SM MIR in kbps for each SM type is:

4 Mbps SM = 4000

10 Mbps SM = 10000

20 Mbps SM = 20000

40 Mbps SM = 65535 (displays Unlimited in the Home > General Status tab)

Motorola PMP 100, PMP 400, PTP 200 (OFDM, PTP 100 (FSK) manual Bam

PTP 100 (FSK), PMP 400, PTP 200 (OFDM, PMP 100 specifications

Motorola has long been a key player in the wireless communications market, known for its innovative solutions that cater to various connectivity needs. Among its diverse product range, the Motorola PMP 100 and PTP 200 series stand out as robust solutions for both point-to-multipoint (PMP) and point-to-point (PTP) applications, utilizing advanced modulation technologies such as OFDM (Orthogonal Frequency-Division Multiplexing) and FSK (Frequency Shift Keying).

The Motorola PMP 100 series is designed for wireless broadband access, enabling operators to provide high-speed internet connectivity to rural and underserved areas. Its capability to support multiple users makes it an ideal choice for ISPs looking to deliver last-mile connectivity. The PMP 100 operates in the 2.4 GHz and 5.7 GHz frequency bands, ensuring flexibility and compliance with various regulatory requirements. One of its key features is the use of OFDM technology, which enhances spectral efficiency and minimizes interference, resulting in reliable data transmission even in challenging environments.

On the other hand, the PTP 200 series focuses on point-to-point communication, offering high-capacity backhaul links between two locations. The PTP 200 is optimized for performance in line-of-sight scenarios, featuring advanced antenna options and narrow beam width capabilities. This product also leverages OFDM technology, which provides increased data rates and improved capacity, supporting applications such as video surveillance, voice over IP, and enterprise connectivity.

In addition to the PMP and PTP 200 series, Motorola also offers the PMP 400 and PTP 100, which utilize FSK modulation. The PMP 400 series further advances the capabilities of wireless broadband access, featuring enhanced error correction, allowing for better performance in adverse conditions. This series is particularly well-suited for environments with high noise levels, making it a reliable choice for industrial applications. The PTP 100 series, on the other hand, operates effectively in point-to-point scenarios with lower bandwidth requirements, ensuring cost-effective solutions for dedicated leased line services.

In summary, the Motorola PMP and PTP series represent a comprehensive suite of wireless communication solutions, utilizing advanced modulation technologies like OFDM and FSK to deliver high-speed, reliable connectivity. These products demonstrate Motorola's commitment to innovation, addressing the diverse needs of users ranging from ISPs to enterprise customers, all while ensuring robust performance and ease of deployment in various environments.
