2 Pint T - Pint Often there is a need t wirelessly cnnect ne device t anther. In this type f Pint-T-Pint system, Raven has mre wireless data ptins fr wide-area cverage than any ther cmpany square km RV-M50 Daisy series mdem in 915MHz unlicensed ISM band ,000 square km RV-M7 series in licensed VHF band. 40 4,000 square km RV-M7 series in licensed UHF band 20 10,000 square km RV-M8 series OEM mdules in licensed VHF, UHF, and 220MHz bands. All f the abve mdels can be cnfigured fr pint-t-pint cmmunicatins. Used licensed UHF r VHF when yu have a dedicated radi channel fr yur use. The RV-M50 Daisy mdem fr use n license-free ISM channels in the MHz range. Pint T - Multipint Often there is a need t wirelessly cnnect ne device t many ther devices, such as SCADA systems, remte cntrls and GPS tracking. All Raven data radi mdems that wrk in Pint-T-Pint mde will als wrk in a Pint-T-Multipint mde. The flexible addressing scheme built int every radi allws sending and receiving data t/frm individual devices, r bradcast t grups r all devices. The RV-M50 Daisy Mdems have lng range easily (1-20km), and are very lw cst and lw pwer s it is mre practical t use an M50 t link multiple devices than it is t wire them up. With 100 times the cmmunicatin range r Wi-Fi r Bluetth, Daisy Mdems are the reliable slutin fr the last-mile link fr GPS tracking, smart-grid applicatins, remte cntrl f pwer, gas, and water, and industrial M2M applicatins. With the trend twards real-time cnnectivity and access t all machines and data, Daisy- Chain yur multipint netwrk with the secure RV-M50 Daisy Mdems t create yur wn private Internet f Things.

3 Private Wireless Cverage Cver 10s t 100s f square kilmeters with Raven s Daisy radi mdems. Raven uses LRa technlgy frm Semtec t get this utstanding cverage at very lw csts. Fr even wider area cverage, use highpwer licensed VHF/UHF band radi mdems t cver a whle city. Or install many Daisy Hubs arund the area t get the cverage yur system needs. Put as many hubs in the area t get the cverage yu need and increase reliability. Challenges Ging the Last Few Miles Mst public wireless technlgies such as WiFi, Bluetth, Zigbee, Zeewave, perate n public license-free radi channels. Many cmpanies have learned the hard way that these frequencies have sme insurmuntable challenges: A. Shrt Range. These ISM band prducts designed with 20+ year ld wireless technlgy have very limited cmmunicatin range. Usually nly hundreds f meters. B. Interference. With millins f spreadspectrum devices perating within miles, mesh netwrks ften break and wireless links cme and g. Using wireless mdems n licensed frequencies allws radi mdems t use mre pwer, have less interference, and dedicated channels. With great RF system design, pwerful base-band prcessing, and an efficient verthe-air prtcl, lw-pwer radi mdems can be made t wrk many miles. A. RF System Design. The mdulatin, baseband DSP, filtering, RF frnt-end, pwer amplifiers, scillatrs, and link can all be ptimized. B. Range vs Data Rates. The biggest challenge all radi systems face. 10X faster data will always have 1/10 th the pwer-perbit and half the range. M2M cmmunicatins use s much less data than cnsumer apps, s a dedicated wireless data netwrk fr M2M cmmunicatins can have utstanding radi cverage.

4 Daisy Overview Daisy Mdems are inexpensive but still lng-range wireless links. Raven prduces many industrial radi mdems with 2-5 watts f transmit pwer, and frequencies in the 100MHz t 500MHz licensed frequency range. These lwer frequencies and high pwer enable these radis t reliably cver square miles. See ur data radi prducts at When an applicatin nly needs a wireless link that wrks a few miles, ur Daisy Mdems will get the jb dne at a much lwer cst. Our Daisy mdems use very sensitive lngrange LRa transceivers. Hw d they get such amazing rang? A. They use 900MHz RF instead f 2.4GHz. Link margin is 1/F s the lwer the frequency, the better the range. B. Advanced mdulatin techniques enabled almst 10X better receiver sensitivity. C. Lw bit-rates fr M2M increase the signal/nise rati by 10 t 100 times. D. Pwerful frward-errr-crrectin repairs crrupted data bits Add all f the abve up, and yu can see hw ur Daisy radi mdems can wirelessly extend yur netwrk ut many miles. And because ur Daisy mdems are highly integrated, they are small and very inexpensive. Small saves mney, pwer, and makes them easy t integrate int OEM prducts, meters, and ther devices. Each Daisy Mdem is assigned an IPV6 address, has multiple levels f security and encryptin, and a very flexible I/O fr cnnectin with mst any type f machine.. Pint-t-Pint Daisy Netwrk Optins Tw r mre Daisy Mdems can be cnfigured t cmmunicate with each ther in a traditinal radi mdem way. Each is assigned a unique ID, and using the IDs,

5 messages can be sent frm ne Daisy Mdem t ne r mre ther Daisy Mdems. If the GPS tracking feature is rdered with the Daisy Mdem, then the Daisy Mdem can be used as a GPS transpnder. Any ther Daisy Mdem within radi range can track it (assuming the security credentials are cnfigured n all transpnders). Pint-t-pint netwrks require n ther infrastructure. N base statin, n internet cnnectin, n ruter, n ther hardware is needed t make a lcal wireless netwrk. T cnnect a machine t the internet, r sme ther netwrk r device, all that is needed is the apprpriate I/O interface n ne f the Daisy Mdems. All mdems cmmunicate thrugh their serial interfaces as RS232/422/485/USB. Device addressing is built int the prducts, and may be cnfigured by the user. The RV-M50 Daisy mdem uses a digital serial interface fr easy integratin int yur prducts. It is als available in the Tech Series enclsure with its RS232, RS422, RS485, USB, and digital interface ptins. There is als an embedded Arduin CPU ptin with this enclsure. See fr mre infrmatin abut this versatile enclsure. Pint-t-Multipint Dzens t thusands f Daisy Mdems can be used in a pint-t-multipint cnfiguratin with the use f ne r mre Wireless Hubs. Each mdem cmes assigned a unique IP6 address, and using the IDs, messages can be sent frm ne Daisy Mdem t ne r mre ther Daisy Mdems. The managed Wireless Hub in a Daisy netwrk is a very pwerful cmputer that makes wireless cnnectivity t yur end devices easy, reliable, and secure. Wireless Hub Functins:. A. Device authenticatin. Ensures the devices n yur pint-t multipint system are nly the devices yu authrized t be n yur system. B. Data ruting. Transfers data between wireless devices, r between yur servers and the wireless devices. C. Manages Security. Depending upn the security level yu chse, the Wireless Hub manages security and encryptin prtcls and authenticates devices. Expandable Wide Area

6 Dzens t millins f Daisy Mdems can be used in a wide-area pint-t-multipint with many Wireless Hubs used t expand system cverage as needed. The Wireless Hubs in a wide-area Daisy netwrk cmmunicate amngst themselves t frm a huge wireless netwrk. 1 t 50 hubs may be used n a single Expandable Wide Area netwrk. Yur servers/wrkstatins that need access t any r all f the devices cnnected t the Daisy Mdems need nly access ne f the ne Master Hub t send and receive data. Data may be cmmunicated in/ut f the wide area netwrk using: A. IPV6 packets B. Telnet sckets C. SSH cnnectins D. WMX packets Need mre cverage? Just install mre Wireless Hubs. Raven s Wireless Hubs are very ecnmical, and each ne will add miles f cverage. The Wireless Hubs autmatically cmmunicate between themselves t pass data, hand-ff Daisy Mdems, authenticate users, and keep the netwrk secure. Cmmercial Netwrks If yu want t cver millins f miles, billins f end-pints, and have thusands f custmers, then a DART netwrk with Daisy Mdems as endpints is a very ecnmical slutin. See fr mre infrmatin abut Raven s wide-area DART technlgy. Platfrm Optins M2M cmmunicatins and the Internet Of Things (IOT) ften benefit frm utilizing a gateway platfrm with built-in applicatins. Yu can perate Daisy Mdem withut any

7 platfrm because their interfaces are s versatile, but Raven als has a number f platfrm ptins. Wireless Hub. It is a Linux cmputer, and Raven can assist yu with implementing yur apps n the Wireless Hub. Lcate a Wireless Hub at yur netwrk site, and any Daisy Radi within range will be able t send and receive data t/frm the Hub. The HUB gives yu IP access, serial access, and telnet access t yur devices that have incrprated Daisy Mdems. The Wireless Hub als authenticates the Daisy Mdems and securely encrypts the cmmunicatins s that yu private data stays private. Cigrn Gateway. ( ) Cigrn is an pen-surce wireless ruter designed fr SCADA and wide-area data ruting frm multiple base statins. DART. Raven has develped a server and prtcl technlgy called DART (Dynamic Autmatic Radi Transmissins). Daisy Radi mdems any sme ther f Raven s radi mdems supprt the DART prtcl, s ne netwrk built with DART Wireless Hubs and a DART Master Gateway can supprt thusands f Hubs and billins f Daisy Radi ndes. See fr mre infrmatin. DART Gate. An applicatin by Raven used t manage a wide-area wireless netwrk. It lets users mnitr and manage their netwrk, and link databases t each device fr GPS tracking and inventry management. Tracking Things Daisy Mdems with their GPS ptin are utstanding GPS transpnders. Because they are lw-cst, lw-pwer, and lng-range. Daisy Mdems can be used fr lcatin-based inventry cntrl, theft detectin, and traditinal AVL. The RV-M50 Daisy Radi GPS transpnder is als available in a weatherprf enclsure with built-in battery and antennas fr persnal and asset tracking. It is mdel number RV-V50. All Daisy Netwrks supprt GPS tracking applicatins. Raven has a RavTrack PC prgram fr GPS tracking, and many ther sftware apps are available t track Daisy Transpnders. Great Cverage with N Mnthly Fees. RV-V50-EC Daisy GPS transpnders can be tracked frm many miles away. That may nt be enugh fr yur needs, s simply add mre Wireless Hubs t expand yur cverage t as large f an area as yu wish. Fr example, if yu were a autmbile dealer wanting t track yur inventry, r a schl district wanting t track schl busses, put a Wirelss Hub at ne facility t track every vehicle within miles f that lcatin.

8 Add as many Wireless Hubs as yu need t cver yur area. Raven s Wireless Hubs have an autmatic Mesh capability s that they act like n big Hub instead f many diverse netwrks. Lgin int the master Wireless Hub n yur netwrk and it will give yu access t all devices within range f all f yur Wireless Hubs. Track yur vehicles n-site r within miles f yur lcatin Add a Wireless Hub at yur Other lcatins t expand Cverage The Wireless Hubs d nt have t be within radi range f each ther. Spread them arund the city, the state, r the cuntry t expand yur cverage.

9 Tracking in The Clud r a Persnal Clud Daisy GPS trackers with their expandable cverage and n mnthly fees are the mst ecnmical way t GPS track vehicles, busses, assets, rental equipment, r almst anything. Use a server in the clud r yur wn private clud t access yur infrmatin. Raven ffer clud-base GPS tracking if yu want t use ur service, r purchase a Dart Gate server applicatin t hst yur wn GPS tracking server. The Daisy Hub prvides secure access t yur GPR tracking data, s yu can utilize yur wn GPS tracking applicatins, r use Raven s ptins, r many ther cmpany s sftware. Raven s Dart Gate web platfrm has unique features that let yu custmize the userinterface and the data that is displayed related t the things yu are tracking. Access yur things lcatin infrmatin using a web brwser, Andrid tablet, r any mbile device. And yur users can als access the custmized infrmatin yu stred fr the things yu are tracking. Fr example, an autmbile dealer can als stre their car s clr, VIN number, price, year, mdel, ptins, and lts f ther data fr each car. A schl district can als stre the driver s name, bus mdel, maintenance infrmatin, rute number, and child cunt in Dart Gate. When this type f infrmatin is stred in Dart Gate, users can srt and view their things by any r all f the fields. Fr example, an aut dealer can get a list f all red cars with a price less than $25,000, and then display them n a map.

10 Why hst yur wn tracking server? Technical Specificatins are subject t change withut ntice. 1. Security. Yu cntrl and limit access yur infrmatin. 2. Cst. Dart Gate server is easy t hst, and fr medium sized systems, a hsting cmpany may nt be needed. 3. Custmizatin.
