LOBOMETRICS PUSHES PERFORMANCE TO THE LIMIT

The Lobo 900 series radios have a maximum throughput of around 90 Mbps (per radio), but, as real world deployments involve activating services, such as filtering, firewalling, NAT and other features that add memory overhead and consume CPU cycles, the performance achievable in average deployments is a throughputs between 17 Mbps and 90 Mbps (depends on model). In deployments where the Lobos will be connected to third party equipment, performance may be limited by the others side.

Lobo 900 series throughput is impressive, specially if we consider the fact that an average access point has a throughput of between 14 Mbps and 21 Mbps (PC Magazine benchmarks of 14 brands) in a perfect connections of just 60 feet distance. Lobo 900 series will easily give you much faster links at distances of not just a few feet, but many miles.

The amazing performance of the Lobo 900 series is achieved by applying the latest technologies.

• Real time data compression performed by the radio CPU

The makes wide use of the Adaptive Lempel Ziv Hardware Compression Engine that is embedded in the chipset. The hardware analyzes network traffic and compresses it in real time using the reliable, standards-based algorithms employed by popular data compression software. With mixed network traffic, the Hardware Compression Engine provides 10 to 30 percent additional throughput without side-effects.

• Packet/Frame Bursting

The Lobometrics wireless devices use advanced 802.11a, e, g, and h features to enable a standards-compliant bursting capability for 108Mbps and 54Mbps single and mixed mode connections. This technique adjusts data frame, acknowledgement and response parameters according to the number of users, level of wireless activity, and other network conditions.

Frame bursting is a transmission technique supported by the draft 802.11eQoS specification. Frame bursting can increase throughput when communicating with 802.11a, 802.11b and802.11g standards-compliant devices. Frame bursting increases the throughput by reducing the overhead associated with the transmission.

Standard transmissions are separated by a time period called Distributed Interframe Space, (DIFS), during which all clients contend for airtime to transmit their data. After successfully transmitting one frame, other products contend for the airtime again, if they have more data to send. In a burst trans-mission, the unit contends for the airtime once, before sending a series of data frames in quick succession. As a result, the overhead of contending for airtime and dead time between frame transmissions is reduced.

The Lobometrics systems support the timing necessary to burst transmissions. If it is communicating with an access point that does not acknowledge burst transmissions, it falls back into non-burst mode.
 

• Fastframes
  
  By using frame aggregation and timing modifications increased data throughput is obtained by transmitting more data per frame.
  
  Fast frames increase data throughput by increasing the number of bits sent per data frame by bundling two data frames into a single LAN frame, thereby eliminating the extra wireless overhead of sending the second frame. Typically, frames transmitted over the wireless medium are bridged to Ethernet, and therefore are restricted to the maximum Ethernet frame size of 1500 bytes. Fastframes operate by changing the algorithms that determine how the actual data frame is structured, and the result is additive to the frame bursting effect. Once fast frames have been negotiated with an access point station link, both the access point and the station can send wireless frames of 3,000 bytes to the corresponding peer. This technique is also based on the802.11e draft standard.
  
   
• Dynamic Transmit and Modulation Optimizations

Based on measurements of the RF environment, the designs dynamically optimize transmit timings and adjust modulation parameters to improve 802.11a/g communications. This increases the multipath resistance of the signal while enabling the use of higher modulation and coding rates, and the effective throughput. DTMO is particularly suited for hash environments and long distance links.

• Double radio in traditional AP-Client modes or Range Extenders

In AP mode or as range extender, bridge extender or WDS, multiple radios improve performance and client capacity up to almost 200%.

Additional point-to-point and point-to-multipoint performance is achieved by :

• Two channel bonding in single radio systems

The radio sub-systems in the Lobometrics single radio systems can apply a technique called cannel bonding which makes concurrent use of two channels instead of one in its wireless connections, doubling bandwidth in the same way that adding two ADSL doubles bandwidth. This technology is only applicable in connections between two Lobos, for example in a point-to-point backhaul, or in a point-to-multipoint WDS meshed network.

• Four channel bonding in double radio systems

Breathtaking speed can be achieved by making four channel connections with Lobometrics double radio systems. The performance obtained is not comparable to any other wireless networking device in its category, including test with new technologies like 802.11n or WiMAX. Lobo Quad-Bonding connections have a bandwidth of 80 MHz.

• NEW : Eight channel bonding in double radio systems
  
  Up to 400Mbps throughput with its exclusive 160 MHz. bandwidth
