  1. VULCAN Vs MERCURY TECHNOLOGICAL DIFFERENCES AND APPLICATIONS

  2. ConnectionMode Forconnections of type: • Point to Point (radio link between two devices). • Point to Multi-Point. For connections of type: • Point to Point. • Point to Multi-Point. • Access Point (AP). • Wireless client. VULCAN MERCURY

  3. Media Access Control TDMA (Time DivisionMultiple Access): • Data coming from multiple sessions and with a specific period of time is transmitted by the media. TDD (Time DivisionDuplex): • By means of the same frequency channel, transmission and reception are made in different periods of time. CSMA/CA (CarrierSenseMultiple Access withCollisionAvoidance): • This media access method is similar to the use of HUB equipment. The devices implementing this technology must “listen” the radiofrequency channel before transmitting the data required for communication. • Collision avoidance is required. VULCAN MERCURY

  4. Wi-Fi Compatibility • It is not compatible with Wi-Fi products because the protocols of Data Link Layer and Physical Layer are different. • It is compatible with Wi-Fi products. • Under IEEE 802.11a/b/g standard. VULCAN MERCURY

  5. Data Rate by Session • It keeps the data rate by session at a limited faraway distance. • It works with DRS (Dynamic Rate Switching). • As the wireless client distances from the AP, the data rate adjusts to low speeds. VULCAN MERCURY

  6. Utilizable FrequencyBands • The devices can operate in the frequency bands ranging from 450 MHz to 7 GHz. • Special custom-made frequencies available under request. • The devices can operate in the 2.4 GHz ISM and 5 GHz UNII-1, UNII-2, and UNII-3 frequency bands. VULCAN MERCURY

  7. Session Management • Multiple sessions can be managed at the same time by means of the TDMA/TDD technology. • Each session is assigned a data rate. • Sessions compete for accessing the shared media. • QoS can be enabled for multimedia sessions. VULCAN MERCURY

  8. Mobility • Mobile clients can move around the cell up to 80 Km/h without losing synchronism. • Mobile clients can move (in certain cases) around the cell, but at low speeds. • It is not recommended for connecting mobile devices in motor vehicles. VULCAN MERCURY

  9. Line-of-SightRequirement • Almost-Non-Line-Of-Sight (ANLOS). High power VULCAN UHF Radios do not require line of sight, with the exception of very extreme conditions. • VULCAN Radios in 2.4GHz and 5GHz do require line of sight for operation. • Site Survey in the location is recommended. • Line-Of-Sight (LOS). among the devices to be linked wirelessly is required, because they work in very high frequencies. • Site Survey in the location in recommended. VULCAN MERCURY

  10. ODU Unitsor Radios Costs • Average cost. • Less expensive than VULCAN devices. VULCAN MERCURY

  11. Client Devices Costs • VULCAN CPEs or client devices have an average cost. • MERCURY CPEs or client devices are very economical. VULCAN MERCURY

  12. Forward ErrorCorrection (FEC) • It integrates the FEC technique for reliable delivery of data, and allows the correction of corrupted “bits” by means of correlation algorithms with the redundant “bits”. • The FEC technique is used for error control in the data transmission over noisy an unreliable communication channels • It does not implement the FEC technique. VULCAN MERCURY

  13. Bandwidth Availablein the Channel • VULCAN UHF radios can be configured for 5 and 10MHz bandwidths. • VULCAN Radios operating in high frequencies con operate with bandwidth up to 40MHz. • In 2.4 GHz models, the bandwidth available is 22 MHz. • 5 GHz models of radios use 20 MHz bandwidth. Except the LP-288ai in Turbo Mode which support 5/10/20/40MHz bandwidth. VULCAN MERCURY

  14. Data Rate/Distance Ratio • These devices keep the data rate (Mbps) stable at faraway distances. • Because of DRS, these devices vary the data rate and adjust it depending on the quality level of the wireless signal. VULCAN MERCURY

  15. Power Supply Power sources available: • 12 VDC, 24 VDC, and 48 VDC. • 120~240 VAC. • Integrated proprietary PoE technology. Power sources available: • 24VDC and 48 VDC. • 120~240 VAC. • Integrated proprietary PoE technology. VULCAN MERCURY

  16. Full-Duplexor Half-Duplex Sessions • Full-Duplex sessions are simulated by means of TDMA/TDD. • Half-Duplex sessions only. VULCAN MERCURY

  17. Applications • PtP and PtmP links for long distance. • Last mile services. • Backhaul. • Telemonitoring. • Multi-sessions links with QoS. • Highly mobile networks. • Links with no line-of-sight required. • Business, industrial, and military applications. • DC mobile versions. • Wi-Fi cells. • Last mile service. • Hotspot. • Internet access. • Networks of free frequency bands. • Line-of-sight required for optimal performance. • Repeating points and wireless bridges. • Applications for small, medium, and large companies.
