Redefining Broadband Wireless
The fundamental value of any wireless product is its ability to generate sufficient capacity in area coverage at a cost that allows a positive return on investment.
The obstacle to achieving this goal is simple attenuation RF, which imposes limits to balance the conflicting goals of proximity (to improve capacity) and long (to extend coverage and reduce costs). For example, a point of base station tower to-multipoint high capacity provides customers in the area, but decreases with the ability to remotely. To address the degradation of capacity, a point to point link may be deployed in the tower at a point of station basic distance-to-multipoint optimally located to provide better outreach and capacity building, but an increase in significant costs.
The best way to summarize the mutual exclusivity of near and long term is the expression:
"Cost, Coverage and capacity: pick two "
Wireless broadband, therefore, is defined by these constraints:
1. Low cost and long-term but with limited capacity.
2. Low cost and high capacity, but only very carefully.
3. At long distance, high capacity, but high cost
SkyPilot, however, has patented a high-speed wireless system overcomes these limitations. Although it is still bound by the attenuation of RF signal, SkyPilot is able to provide the economy moving for wireless operators by extending the coverage and capacity to improve through an innovative architecture called Wireless SyncMesh ™.
SyncMesh – Redefining Broadband Wireless
Faced with seemingly impossible goals high capacity, long-term and low cost, SkyPilot developed a patented Synchronous switching of up to broadband wireless. These systems coordinated by the protocol SyncMesh ™, dynamic antenna pointing directional high gain throughout an interconnected network of stations basis.
With this architecture, each base station covers 360 through eight individual antennas of 45 °. The base station of these switches dynamically between a high gain (18 dBi) antennas to provide both long distance point-to-multipoint links to CPE and long distance point to point connections with other stations base. Dynamically the network of base stations with a link point to point, SyncMesh can enable multi-hop wireless network at each base station operates as a relay "To expand the coverage area. Therefore, the dynamic change of the antenna, each system includes point to point relays, multi-hop and the nearest point to multipoint in a single system to extend the range and reduce costs.
Please note, however, that SyncMesh not simply repeat the signal it is ineffective and unnecessary use of spectrum capacity. Instead, it coordinates and synchronizes SyncMesh transmissions to maximize the capacity of the entire network. By allowing simultaneous transmission of multiple spot beams, SyncMesh attenuates self-interference, and takes advantage of spatial diversity to maximize the reuse of spectrum, which results in efficient use of capacity through the whole spectrum.
With the coordination protocol SyncMesh alignment of directional antennas, SkyPilot has been able to redefine Broadband Wireless
"Cost, Insurance Capacity: Choose one of three"
Enlargement Coverage
To extend the coverage served by each cell tower, SyncMesh use a combination of high gain directional antennas and multi-hop transmission in all base stations in the network. high-gain directional antennas, of course, one the best ways to increase the scope for increasing the budget related to both transmit and receive. They also provide many advanced features SyncMesh that the reuse of frequencies and the attenuation of self-interference.
Distance along Point Backhaul point-
The time intervals synchronized SyncMesh each node dynamically changes the high-gain antenna for optimum coordination of transportation. Since each backhaul link has an address 18 dBi antenna at each end, nodes leverage SyncMesh 36 dBi gain to provide a line of sight (LOS) link up to 10 miles/16 km. These links can also support non line of sight (NLOS) using OFDM, however, ranges NLOS links vary, of course, depending on the type and number of obstructions.
Multi-Hop Relay Range Extension
With multi-hop relay capabilities, each base station can act as a relay node. This allows the range extends from a base station antenna that span multiple hops, each hop 'range extends to 10 km miles/16 as described above. With capacities of multi-hop relay, the scope of the tower is no longer limited to a single base station, but the scope of of the tower can be extended further by a series of interconnected base stations.
Long distance point-to-multipoint links
The same dynamic has changed 18 dBi antennas are also used for point to multipoint. With the base station connects point to multipoint equipment SkyConnector customer premises (CPE), which also has a directional high gain antenna. With these high gain antennas, radios and high power OFDM links, the base station may provide links to the CPE as far as 7.5 miles/12 km.
Complete coverage of routing around obstacles
Extending the coverage is not limited to push the limits of coverage of a cell – an expanded coverage applies to fill holes in coverage. Provide SyncMesh capacity multihop relay, the remote base stations can be routed around obstacles to reach easily and fill holes in coverage.
Efficiencies capacity
SyncMesh is designed specifically for a more efficient use of available frequencies through a mesh of base stations total. When the direction of all the links of mail is considered a set of links, the protocol allows multiple SyncMesh transmit the same frequency with a limited range of interference with a synchronous protocol distributed. This allows optimal reuse of spectrum in a region to increase the total coverage "goodput" for the second time in the air.
OFDM with adaptive modulation
All links using OFDM SyncMesh to provide the best opportunity to close high modulation links, even in NLOS environments. The links are constantly monitored regularly and the modulation in response to changed in the radio environment to ensure optimum performance.
Spatial spectral reuse
One of the main advantages the mesh model of the transmission is coordinated around the idea of "spatial frequency reuse." From SyncMesh coordinates all links dynamic address, several simultaneous transmissions occur on the same frequency, effectively re-using spectrum throughout the coverage area.
The high percentage of modulation
Since we all nodes multi-hop backhaul point SyncMesh point can be easily deployed close to subscribers. This allows the ability to transform "edge of the cell" under the modulation paying subscribers with high modulation to our proximity. With this capability, network-wide average increases in the rate of modulation and optimizes the data rate "Allowing more frequently along the transmission network.
Auto-Interference Mitigation
Following the dynamic switching of directional antennas and synchronization of frequency reuse, spatial diversity SyncMesh used to mitigate effectively self-interference, which results in improvement rate modulation and spectral efficiency in general.
linear scalability of spectrum capacity through the layers
From SyncMesh maximizes the spectral efficiency of a single frequency and optimal reuse of the channel over a wide coverage range, which allows the use of alternative channels to the ability to scale linear. "Layers" alternative channels of coverage of the entire region makes maximum use of available frequencies.
Breakthrough Economy
Thanks to the technical advantages of a broader coverage and more efficient use of spectrum, a large amount bandwidth can be transmitted from a single injection point capacity. When you combine the characteristics of other SyncMesh, which leads to substantial economic benefits.
Extension of Multi-Hop coverage reduces the cost of towers
Multi-hop backhaul increases considerably the coverage radius of a single tower, reducing the number of turns required to provide broadband services in specific areas of coverage. Reduce the number of turns directly related turn reduces the acquisition and backhaul connections rental fees, and the number of rental or microwave for each site.
Integrated backhaul, relay base station and reduce capital costs
The unique integration a point backhaul point, a multi-hop relay, and point to multipoint base station leads to a significant reduction in capital costs of network. Because these functions are not discrete products, there are no additional costs because they are simply integrated in a single network. The ability to reuse the radio for the different functions of the dynamic evolution of directional antennas reduces the overall costs of deployment of broadband wireless.
In addition, there is only one point of detachment. He said that we should mention that coverage of 360 Extender Gateway and means that you have to pay for a dependency on a tour. Most of the space charge of the tower leasing company for each attachment.
Auto Discovery and the antenna pointing system reduces operating costs
SyncMesh ability to automatically discover all nodes and dynamic directional antennas and the AF led to a dramatic decrease in operating expenses. Since each product can cover 360 SyncMesh dynamically changing a separate eight directional antennas 45 degrees, no need for manual scoring the antenna, if the links are point to point, or point to multipoint relays. SyncMesh automatically detects all the nodes and automatically sets all links, thereby reducing operating costs associated with implementing an advanced broadband wireless. This reduces hand "first" operational experience and reduces the total time to deploy.
Additional Benefits SyncMesh
Besides all the benefits listed above, SyncMesh architecture also provides additional features that provide benefits to operators Wireless.
The best route for dynamic routing re-routing and self-healing failover
SyncMesh has the ability determine if you have multiple paths and choose the optimum route. In addition, if the exchange rate or modulation configuration changes Interconnection mesh backhaul links point to point can automatically and dynamically adapt. This optimizes performance and capacity can provide self-healing in case of failure.
Latency guarantees
From SyncMesh is a synchronization protocol can provide low latency, low jitter, and guarantees for latency sensitive traffic like VoIP.
Connections to Wi-Fi
With the synchronization of wireless network operating in the frequency band 5 GHz, which allows each node to provide mesh Wi-Fi All the mesh nodes are available with SkyPilot access points Wi-Fi (PA) at 2.4 GHz and 4.9. It allows Wi-Fi zones spread over large coverage.
"In Ethernet / Ethernet Out
SyncMesh Each network is a complete network of layer 2, which translates to "Out Ethernet / Ethernet" on the network. This architecture supports Layer 2 network Virtual LAN (VLAN) and a wide range of Layer 3 protocols, including IPv4 and IPv6. In addition, when used as transmission facilities for Wi-Fi mobile devices are not required to renew its IP address from crossing borders not subnet. Each high gain directional antenna 21BFrequency flexible support a frequency range of 4940-6075 GHz which allows each node to provide flexibility in the frequency and give operators the opportunity to move new frequencies as needed.
Summary
Although all wireless products are bound by the laws of physics, innovation solutions can help alleviate some of the key constraints. SyncMesh protocol uses the concept of high gain directional antennas to increase the coverage and capacity, but by its patented method of switching between antennas, the advantage of cost associated with systems of omni-directional. Ultimately, SkyPilot has been able to redefine broadband wireless, cost, coverage and capacity: Choose from one of three "
