Install Networking and Wireless Best Practices Toast Infrastructure

Install, Networking, and Wireless Best Practices

Toast Infrastructure • When deploying Toast you are implementing technology stack • The foundation of that stack is the cabling / networking / wireless • If the foundation is bad…the whole house falls down…

Toast Hardware Communication Hard Wired Devices • Terminals (TCP/IP) • Epson T-20 Receipt Printers (TCP/IP) • Epson U 220 B Kitchen Printers (TCP/IP) • Scanner (USB) • Scale (USB) • Customer Display (USB) Wireless Devices • Handhelds (TCP/IP) • Ingenico EMV Reader (Bluetooth) • Mag. Tech MSR Reader (Bluetooth) • Scanner (Bluetooth) ** NOTE – Wireless terminals and printers are not recommended and/or supported!

Networking Best Practices • • • Test All Cables. Make Sure All Cables PASS Test And Connect At 100 MBps FDx Label All Cables And Networking Devices Used By Toast Setup DHCP Lease Time On Meraki To Maximum Available (7 Days) Turn OFF Wifi On Meraki Z 1 Use 5 -Port Switch Connection Standard • • P 1 Uplink; P 2 1 st POS; P 3 1 st Receipt Printer If the customer has a managed network, a representative from the MSP must support, ideally be present at, the installation

Wireless Best Practices • Install Wireless Access Points (WAP) On Ceilings Only • Make sure WAP “top” Is Never Blocked Or Facing Away From The Coverage Area • Make Sure WAP Is At Least 3 -5’ Away From Any Other Radio Sources • Enable “Band Steering” • Turn 2. 4 Ghz Radio Off (Meraki Only)

Wireless Best Practices Cont… • Update Names Of WAPs On Meraki And Cloud. Trax Dashboards • Make Sure WAP Is Setup To Use The Least Used Channel In The Area • Make Sure WAPs Are Using Non. Overlapping Channels • Make Sure WAPs Channel Width Is Set To 20 Mhz On Meraki And Cloudtrax Dashboards

Wireless Best Practices Cont… • Guest Wifi • If the customer has their own “completing” wifi running, you must have whomever manages that network do three things: 1) Lock the network down to the 2. 4 GHz spectrum if possible 2) Turn off band steering if applicable 3) Turn off channel hopping if applicable and ensure that the static channels are non-overlapping with the Toast secure network

Wireless Planning

Wireless Planning – Overarching Principles • Less is more – Each WAP should be able to cover ~30 feet in all directions • Environment plays a big factor here – the more open the environment the more coverage you’ll get • Our access points (and most omni-directional APs) get the best coverage when the antenna is facing downward • If an area has line of sight to the AP and is within ~30 feet, it should get coverage • Kitchens shouldn’t have wireless installed. If the restaurant needs servers to interact with the POS in the kitchen then a terminal should be installed

Wireless Planning – Overarching Principles Cont… • If you’re installing access points within 30 feet of each other, in addition to nonoverlapping channels you may need to adjust the power on each AP to ensure the tablets will transition from 1 AP to the next properly • Handhelds generally do a bad job at transitioning which is why tuning the power is sometimes necessary • If you’re operating in the 2. 4 GHz spectrum for some reason, you may have excellent signal strength but little to no connectivity. These dead spots can be caused by competing wireless devices that use the same frequencies as Wi-Fi, but do not cooperate with Wi-Fi. Here a few common devices that cause 2. 4 GHz dead spots: • • • Cordless Phones Wireless Audio Systems Camera Systems Microwave Ovens Wireless Security Systems

Wireless AP Planning 2. 4 GHz 5 GHz • Ensure Coverage - Notice the overlapping coverage so that Wi-Fi roaming works effectively (no dead spots) • Avoid Channel Overlap - Notice that 2 APs with the same channel are never overlapping (it’s a bit more complicated than this, see next slide)

Channel Overlap 5 Ghz Spectrum • You should always measure the spectrum and choose non-overlapping channels with the least activity • 2. 4 GHz Non-Overlapping Channels – 1, 6, 11 • 5 GHz Non-Overlapping Channels (see image to the left) • • Preferred – Band A 1 and C DFS (ok but avoid if you can) – Band A 2 and B • Can get interference from military / weather radar

Wireless Testing • Always use a Toast handheld to perform the testing / tuning • Leverage “Wi-Fi Analyzer” on your tablet • Make a logical diagram of the WAP locations and the tested signal strengths at the corners of the environment

Wireless Testing - Signal Strength Definition Signal Strength Quality Description -30 d. Bm Amazing Maximum achievable signal strength. The client can only be a few feet from the AP to achieve this. Not typical or desirable for the entire environment in the real world. -67 d. Bm Good (-50 d. Bm would represent very good) Minimum signal strength for applications that require very reliable, timely delivery of data packets. The closer to -50 d. Bm the better. -70 d. Bm Okay Minimum signal strength for reliable packet delivery. Toast can operate in -67 d. Bm -70 d. Bm environments but you may see some system instability leading from the wireless signal quality (reappearing checks, delayed printing, missing orders, etc. . ). -80 d. Bm Not Good Minimum signal strength for basic connectivity. Packet delivery may be unreliable. Toast will not function reliably at this signal quality. -90 d. Bm Unusable Approaching or drowning in the noise floor. Any functionality is highly unlikely.
