Wireless High Speed Internet
Available bandwidth, low latency and achievable signal-to-noise ratio determine the maximum possible throughput for subscribers and good performance in Wireless High Speed Internet communication systems.
High bandwidth for low and high-density residential areas
We offer a wireless high speed internet solution for low and high-density residential areas:
|WiDOX 3.1 and MiLTE
|WiDOX 3.1 and MiLTE provide their respective services areas with high speed internet services. WiDOX 3.1 achieves the same download speeds for subscribers at the edge of the service area as for those close to the base station, whereas with MiLTE there may be some degradation towards the edge of the service area.
|WiDOX 3.1 and MiLTE combined allow the addition of subscribers inside a high-density service area, e.g., the city, where we can add more subscribers using bandwidth (channel) bonding, as long as more channels within the licensed spectrum are allocated. Download speed is what matters most in the majority of network activity—watching movies, reading newspapers, or even playing games and the WiDOX 3.1 solution will achieve the same download speeds regardless of distance from the base station. However, users are increasingly sending videos and photos to others, and therefore, there is a growing additional demand for upload speed. We optimize upload bandwidth with four parameters—channel bonding, power, channel width, and modulation to deliver the best experience.
|Dynamic and Policy Based Caching
|For schools or organizations, where the same sites are visited repeatedly, to reduce bandwidth usage, we offer Dynamic and Policy Based Caching. Previously visited websites are automatically cached (Dynamic), or websites that are planned to be visited (Policy Based Caching) are downloaded at a central site and then multicast to local sites and stored on the local disk of the SchoolAxxess or OfficeAxxess server. Our caching application checks if the stored copies have been changed before they are served to clients.
Minimal latency makes it a easy choice
Operators and subscribers, via speed test applications, regularly measure packet data latency. In some instances, e.g., where the delivery of small packets of information are required quickly, latency is more important than bandwidth, e.g., where one click delivered faster would win you the game. Low latency also adds quality of experience for VoIP or video conferencing. Real-time applications, such as remote control of movement (e.g., telemedicine) not only benefit from reduced latency, but also require it. With WiDOX 3.1 and MiLTE, once data information leaves the transmitter and antenna, it travels through the air at approximately the speed of light, with no additional latency, compared to cable solutions (fiber, copper, coaxial) where the common achievement is 40% to 80% of the speed of light. Compared to satellite communication, where data needs to travel long distances through the atmosphere and space, adding to latency, our base station is closer to the end customer and this further improves latency. Our hardware solutions improve signal quality yet do not add any additional latency.
Quality signal reception
The quality of the signal received by radio devices is determined by comparing the desired signal level to the background noise level in the signal, and this is known as a Signal-to-Noise Ratio (SNR). High SNR ensures that the data transmitted is kept intact, resulting in higher data speed. Advintive can often increase the transmitted signal by increasing the transmit power, or filtering to reduce noise. Additionally, Forward Error Correction (FEC) is also added to the data to allow the receiving device to correct some of the received data error and thereby eliminate the need to retransmit the data. WiDOX 3.1 and MiLTE also support Orthogonal Frequency Division Multiplexing (ODFM) technology that allows rebuilding of signals corrupted by noise. These factors play into WiDOX 3.1 and MiLTE offering high quality signal reception.
When engineering our systems, we focus on decreasing the noise. This can be achieved by decreasing the band width, e.g., when the band width is decreased by 50% there is an improvement in SNR by 3 dB. In WiDox3.1 the channel size (spacing) is 25 kHz, which would provide 240 sub-channels (6 MHz/25 kHz) in a 6 MHz channel. In MiLTE 15 kHz channels in a 20 MHz bandwidth would provide for 1200 sub-channels; or 600 channels in a 10 MHz bandwidth.
Our receive-processing-unit (RPU) at the base station works to further reduce the noise in the received signal. The amount of unwanted noise caused by interference from other radio systems is limited, since we operate in licensed or semi-licensed spectrum.
Clear line of sight benefits
Advintive technology solutions require near line of sight, which means many obstructions are accommodated, e.g., signal loss due to foliage and small buildings is significantly lower in the UHF band.
Continuous monitoring for high quality
Our system monitors each single cable modem at the subscriber site for latency, downstream and upstream signals and SNR, data throughput, and data usage. This data allows the operator to easily troubleshoot connectivity problems, maintain quality, and manage subscriber billing. Using monitored data reports, Advintive can remotely optimize the system parameters for highest high speed internet experience.
