TM Simple Satellite Network Solutions Radyne SkyWire Company Proprietary -- 1
SkyWire is a next generation product TM designed specifically for IP networks running over satellite. SkyWire is an extremely efficient, easy to use, TM low cost TDMA network platform purposely engineered for small to mid size networks. Radyne SkyWire Company Proprietary -- 2
SkyWire allows for True Full Mesh, Hub and TM Spoke, or Hybrid networks. All on one platform. SkyWire has no expensive hub equipment, TM does not require an M&C system, does not require high stability clocking and you won t need a 5-Day training course to use it. Radyne SkyWire Company Proprietary -- 3
Features True full MESH TDMA VSAT solution: Anywhere to Anywhere single hop Simple modular expandable design Best TDMA Bandwidth Efficiency in the Industry Low cost of entry: scalable, start with as few as 2 sites Fastest response time - single-hop BW allocation IP Layer 2 device Unsurpassed packet per second throughput Hubless no expensive network controller No annual license or maintenance fee s No central clock or GPS required No extensive training required to setup and operate Will not become obsolete if network requirements change Up to 32 remote sites connected in a True full MESH network using a single 1 RU box Radyne SkyWire Company Proprietary -- 4
Modular Design Environmental Prime Power: 100 to 240 VAC, 50 to 60 Hz, Auto Sensing, 40 Watts Optional BUC power supply Operating Temperature: 0 to 50 C, 95% Humidity, Non-Condensing Storage Temperature: -20 to 70 C, 99% Humidity, Non-Condensing Terrestrial Interfaces Auto-Everything 10/100/1000 Base-T Data Auto-Everything 10/100 Base-T Control RS-232 Service Port DB-9 Alarm Port with One Form C and Five Open Collector Radyne SkyWire Company Proprietary -- 5
Modular Design Based on one simple building block MDX420 Each gateway has One burst modulator Up to four burst demods Network control module for distributed intelligence All IP data traffic passes through a common 10/100/1000 switch All gateways at all locations are based on this one platform Radyne SkyWire Company Proprietary -- 6
Modular Design Each MDX420 gateway can transmit in one share group One MDX420 gateway can simultaneously receive four share groups Note: Each carrier and thus each share group can run independent modulation and FEC & carriers do not need to be on the same transponder! Radyne SkyWire Company Proprietary -- 7
Satellite Access Because SkyWire is a true TDMA platform, multiple sites time share their transmission. Therefore N number of sites can share one carrier to form a share group : LNB BUC LNB BUC LNB BUC TX RX TX RX TX RX Radyne SkyWire Company Proprietary -- 8
Satellite Access A single share group is shared by N number of sites (ex. 8 sites). Because the MDX420 has up to 4 independent demods, up to four (4) share groups can be simultaneously networked using only one (1) MDX420. Sites 1-8 Sites 9-16 Sites 17-24 Sites 25-32 This example shows how 32 sites are simultaneously networked using only one MDX420. Radyne SkyWire Company Proprietary -- 9
Satellite Access Multiple MDX420 gateways can be chained to increase the number of share groups and thus the number of sites in the network. 10/100/1000 Switch NCM MOD DEMOD 1 DEMOD 2 DEMOD 3 DEMOD 4 MDX420 Sites 1-8 Sites 9-16 Sites 17-24 Sites 25-32 10/100/1000 Switch NCM MOD DEMOD 1 DEMOD 2 DEMOD 3 DEMOD 4 MDX420 Sites 33-40 Sites 41-48 Sites 49-56 Sites 57-64 This example shows how 64 sites are simultaneously networked using two (2) MDX420 devices.

Central Control BW Allocation 1) 2) Server / Scheduler 5 Server / Scheduler 5 1 / Leader 4 1 / Leader 4 2 Site 4 has a information to send to Site 3. Site 4 must request a frequency plan and time slot from the central controller. This takes one full satellite hop. 3 3) 4) Server / Scheduler 5 2 The central controller must process this request along with all requests from all sites and find an available frequency and time slot to accommodate Site 4. Server / Scheduler 3 5 1 / Leader 4 1 / Leader 4 2 The central controller then sends the frequency and time-slot plan to Site 4 and Site 3. This is the second satellite hop. 3 Radyne SkyWire Company Proprietary -- 11 2 Sites 4 and 3 now need to tune freq. and burst in appropriate time-slots per the scheduler. This is now the 3 rd satellite hop! 3
BW Allocation SkyWire works differently With SkyWire s All Ears technology and distributed intelligence BW allocation: No need to talk to a central controller No NEW frequency plan needed No 3-Hop circuit set-up needed Respond to network requirement changes in 1-hop Multiple connections to multiple sites without frequency contention No need to back-off system speed due to frequency coordination Multicast traffic to all MESH sites is sent only one time No Packet Loss 1 2 Each site literally talks to every site in a share group all the time and all sites listen to all sites all the time. 3 5 4 Radyne SkyWire Company Proprietary -- 12
