Answer up front: for a corporate HQ, large office building, multi-floor hotel, warehouse, factory, industrial park, shopping centre or mall across 2000m² for up to 200 users on mixed EE, O2, Vodafone and Three networks, the CW2000 at £935.00 is the pick; it pairs Band 20 at 800MHz 4G data with Band 1 at 2100MHz 3G UMTS data, voice and SMS on every network, cleans the donor with ≥70dB uplink / ≥75dB downlink gain, pushes ≥27dBm output — the highest in the CW series, +7dBm over the CW1000's ≥20dBm, roughly five times the power — behind a ≤5dB noise figure, and ships the high-gain Yagi, 3dBi whip, 10m outdoor plus 5m indoor coax and UK plug. For a 1000m² office, hotel or warehouse for 100 users at ≥20dBm with four antenna zones, the CW1000 at £685.00 saves £250 on the same universal Band 20+1 plan, same gain and included Yagi. For an O2/Vodafone-only enterprise site relying on legacy 2G calling, the CG2000 at £935.00 tunes Band 8 instead of Band 1.

The CW2000-versus-CW1000 gap is a scale, output and antenna-zone step, not a network change: both carry Band 20+1 and universal 3G, both ship the Yagi and both hold ≥70/≥75dB gain, but the CW2000 adds +1000m² (2000 against 1000), +100 users (200 against 100), the +7dBm output step (≥27 against ≥20, roughly five times the power) and ten indoor antennas on multi-way splitters against the CW1000's four on a 4-way splitter. The CW2000-versus-CG2000 gap is a band choice at the same £935.00, same 2000m², same 200 users: Band 1 universal 3G versus Band 8 O2/Vodafone 2G, with the CW2000's higher output and ten zones.

This page compares the three Boost4U chassis side by side rather than in a roundup: the CW2000 at £935.00, the CW1000 at £685.00 and the CG2000 at £935.00. It separates the shared Band 20 data layer from the two choices a buyer must make — how big the enterprise site, how many devices, how much output for ten zones (CW2000 vs CW1000) and which fallback band (Band 1 universal 3G vs Band 8 O2/Vodafone 2G) — and gives a decision tree so the choice follows floor plan, headcount, output need and SIM mix.

All three are UKCA and CE certified, Ofcom licence-exempt, ship free within the UK on 1 to 2 day handling plus 10 to 15 day transit, and carry a 365-day mail return window. None carries 5G; the CW2000 and CW1000 carry Band 1 3G, while the CG2000 carries Band 8 2G instead. All run from the AC 100–240V to DC 5V UK Type plug. The rest of this page numbers every band, £250 step and spec before you order.

Before the tables, three rules keep the comparison honest. First, Band 20 at 800MHz (uplink 832–862, downlink 791–821) is shared by all three and carries EE, O2, Vodafone and Three 4G data, so data capability is not the deciding factor between CW2000 and CW1000; the deciding factor is scale, output and antenna zones. Second, the CW2000 and CW1000 add Band 1 at 2100MHz (uplink 1930–1990, downlink 2110–2180) for 3G UMTS data, voice and SMS on every network, while the CG2000 instead tunes Band 8 at 900MHz for O2/Vodafone 2G. Third, between CW2000 and CG2000 the price, area and users match, so that tie decides by fallback band, output and zones; between CW2000 and CW1000 the band plan, gain and Yagi match, and the £250 decides by area, users, output and antenna count.

Because the CW2000 and CW1000 share the Band 20+1 plan, this comparison never turns CW2000 against CW1000 on network coverage; it turns on whether the site fills 1000m² for 100 users or 2000m² for 200, and whether a ten-antenna multi-floor deployment needs the ≥27dBm output. A single-floor office cannot use the extra 1000m² and 100 users, so the CW1000's £250 saving is rational; a multi-floor HQ, hotel or production hall needs the CW2000's larger area, higher output and ten antenna zones.

Coverage figures assume reasonable donor signal outside and sensible antenna separation; the rated 2000m² covers a corporate HQ or multi-floor enterprise space, and 1000m² covers a large office, hotel or warehouse. On a strong −70 to −90dBm donor the CW2000 can feed up to 10 indoor antennas via multi-way splitters and the CW1000 up to 4 via a 4-way splitter; a weak −97 to −105dBm donor uses the included Yagi aimed at the nearest mast. The tables below compare specs, the £250 step and day-one versus five-year cost before the decision tree.

Read the band row before the price row: CW2000 and CW1000 share Band 1 universal 3G, CG2000 keeps Band 8 O2/Vodafone 2G; then read output, scale, users and the antenna-zone row, where CW2000 adds 1000m², 100 users, the ≥27dBm step and ten zones over CW1000, and matches CG2000 on scale while differing only in fallback band, output and zones.

The £250 between CW1000 and CW2000 buys area, users, output and extra antenna zones, never a new network; the £0.00 tie between CW2000 and CG2000 buys a different fallback band and the higher output rather than more scale. A buyer who stretches CW1000 to a multi-floor HQ pays for a larger tier later, and a CG2000 buyer who later needs EE/Three fallback pays a Band 1 unit on top.

The CW2000 and CW1000 share an identical band plan: Band 20 at 800MHz for EE, O2, Vodafone and Three 4G data, plus Band 1 at 2100MHz for 3G UMTS data, voice and SMS on every network. No network one covers, the other misses; both also hold ≥70/≥75dB gain and ship the high-gain Yagi in the full kit. The £250 difference exists entirely to serve more space, more devices, stronger output and more indoor zones.

CW1000: the 1000m²/100-user commercial unit at £685.00

The CW1000 reaches 1000m² (10,764 ft²) for up to 100 users at ≥70dB uplink / ≥75dB downlink gain, ≥20dBm output, the included Yagi, 3dBi whip and 10m outdoor plus 5m indoor coax, with up to 4 indoor antennas on a 4-way splitter. It suits an office building, hotel or warehouse up to two wings or a single main floor where the active devices sit around four whips. Buyers here should not pay for a multi-floor HQ they never occupy.

CW2000: the 2000m²/200-user enterprise flagship at £935.00

The CW2000 reaches 2000m² (21,528 ft²) for up to 200 users at the same ≥70/≥75dB gain, but outputs ≥27dBm — a +7dBm step over the CW1000's ≥20dBm, roughly five times the transmitted power — and supports up to 10 indoor antennas on multi-way splitters. The extra output spreads the universal Band 1 signal across floors, wings and warehouse aisles that a 4-antenna ≥20dBm unit covers weakly; the extra 100-user headroom keeps a full HQ floor, guest devices and warehouse staff from crowding one cell; the tenth zone reaches an upper floor, far retail wing or production bay that four whips cannot cover.

The £250 step decides by floor area, headcount and output need, not by network

Because band plan, gain and donor antenna are identical, the CW1000-versus-CW2000 choice is a pure sizing, output and zone question: measure the enterprise floor area, count active devices, and only pay £250 when the site genuinely fills 2000m², approaches 200 connections and needs ten cells fed by ≥27dBm. A single-floor office buyer on CW2000 overpays for unused scale; a multi-floor HQ buyer on CW1000 gets weak far floors, a crowded tenth zone and insufficient output for a ten-antenna split.

The CW2000 and CG2000 tie on price, area and users, differing in the fallback band, output class and antenna zones, because both share Band 20 for EE, O2, Vodafone and Three 4G data.

CW2000 Band 1: universal 3G for all four networks at high output with ten zones

The CW2000 tunes Band 1 at 2100MHz (uplink 1930–1990, downlink 2110–2180). On EE, O2, Vodafone and Three this provides a 3G UMTS data, voice and SMS fallback where 4G alone weakens, including MVNOs riding those networks, and the ≥27dBm output spreads that fallback across ten indoor zones. It does not tune Band 8 O2/Vodafone 2G; a legacy 2G-only O2/Vodafone handset that cannot fall to 3G relies on VoLTE or its native network rather than a boosted 2G channel.

CG2000 Band 8: O2/Vodafone 2G only at class output

The CG2000 tunes Band 8 at 900MHz instead, which carries O2 and Vodafone 2G voice calls and SMS, and 900MHz reaches deeper through masonry than higher bands. On EE and Three it provides Band 20 data only with no boosted call fallback; it never tunes Band 1 3G, and its output and zone count follow a lower class than the CW2000's ≥27dBm and ten whips. The CG2000 is the right box when the enterprise SIMs are O2/Vodafone-led and legacy 2G calling matters to those two networks only.

The £0.00 tie decides by call path and output need, not by scale

Because price, coverage and users are identical, the CW2000-versus-CG2000 choice is a pure fallback question: mixed-network HQ, hotel or warehouse needing universal 3G across ten zones with high output = CW2000; O2/Vodafone-only enterprise site needing legacy 2G = CG2000; mixed where both Band 1 3G and O2/Vodafone 2G matter = no single chassis solves both, and a band-specific second unit is required rather than forcing one box.

Walk the branches top to bottom and stop at the first yes.

Branch 1 — Does the property fill roughly 2000m² across floors of a HQ, multi-floor hotel, warehouse, factory, mall or large shop, with up to 200 active phones, laptops and guest devices?

Yes: scale belongs on the flagship CW tier rather than the 1000m² CW1000; move to Branch 2 for the band question. No: under 1000m² for 100 users, jump to Branch 4.

Branch 2 — Do the SIMs mix EE, O2, Vodafone and Three, and do you need up to ten indoor antennas across floors or wings fed by strong output?

Yes: the ≥27dBm output, universal Band 1 3G layer and ten zones matter, so choose the CW2000 at £935.00, Band 20+1, 2000m², 200 users, ≥27dBm, Yagi included, 10 antennas. No and all SIMs are one network with four zones enough: move to Branch 3.

Branch 3 — Are all SIMs O2/Vodafone-led and do the handsets rely on legacy 2G rather than VoLTE or 3G?

Yes: CG2000 at £935.00, Band 20+8, O2/Vodafone 2G calls, accept EE/Three data-only at class output. No (modern VoLTE phones, mixed networks, ten-zone multi-floor site): stay with the CW2000's Band 1 universal fallback and high output.

Branch 4 — Is the job a large office, hotel or warehouse under 1000m² for about 100 users on a mixed-network Band 20+1 plan with four antenna zones and a clean donor?

Yes: CW1000 at £685.00, same universal Band 1 3G and included Yagi on the smaller scale at ≥20dBm, save £250. No and the site grows beyond 1000m²: return to Branch 1 for the CW2000.

Branch 5 — Do you need 5G, a multi-building campus beyond 2000m², more than 200 users, or both Band 1 3G and Band 8 2G at once?

Yes: a £685.00 or £935.00 single-fallback enterprise unit is undersized or band-wrong; choose a larger multi-antenna or band-specific system. No and the site fits 2000m²: return to Branch 1, 3 or 4 and order the matched unit.

Day one, the CW2000 and CG2000 tie at £935.00; the CW1000 sits £250 below at £685.00. The five-year total separates a correctly matched enterprise flagship from a late step-up or second band.

The CW1000 buyer who later moves to a multi-floor HQ or 2000m² production hall steps up a tier rather than stretching a 1000m² unit; the CG2000 buyer who later adds EE or Three devices pays a Band 1 unit on top of the £935.00 already spent. Only the correctly matched single CW2000, CW1000 or CG2000 closes the job day one; over-buying CW2000 for a single-floor office wastes £250, while under-buying CW1000 for a HQ forces a second purchase.

The CW2000 box at £935.00 holds the booster, the high-gain Yagi directional aerial, the 3dBi whip indoor antenna, the UK power adapter, the 10m outdoor low-loss coax, the 5m indoor coax and a mounting bracket; paid variants are 20/30/40/50m external cable and the 18KA protector. On a strong −70 to −90dBm donor, multi-way splitters and extra coax feed up to 10 indoor antennas across floors; a weak −97 to −105dBm donor uses the included Yagi aimed at the nearest mast. The CW1000 box mirrors the cable stack at £685.00 with a 4-way splitter, and the CG2000 box mirrors the cable stack for Band 8.

Basic setup takes 10 to 15 minutes without tools: mount the Yagi with a clear mast view, keep the whip a sensible distance inside, run the outdoor and indoor coax, power from the UK plug, and read steady green before testing across floors. The expansion note reads "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong."

All three carry UKCA, CE and RoHS, are Ofcom licence-exempt, ship free within the UK (handling 1–2 days, transit 10–15 days), and carry a 365-day mail return window. The £935.00 CW2000 price is valid to 2027-10-25, InStock NewCondition, and ships to GB, DE, FR, IT, ES, NL, BE, AT, SE, DK, FI, IE, PT, PL and CZ; the CW1000 at £685.00 and CG2000 at £935.00 follow the same shipping and return terms.

Corporate HQ, multi-floor hotel, warehouse, factory, mall or large retail filling 2000m², up to 200 mixed-network devices, universal 3G across EE/O2/Vodafone/Three with ten indoor zones fed by ≥27dBm: CW2000 at £935.00, Band 20+1, the only chassis that pairs universal Band 1 with this scale, top output and ten antenna zones.

Large office, hotel or warehouse under 1000m² for 100 mixed-network users with a clean donor and four zones: CW1000 at £685.00, Band 20+1, save the £250 you never use.

O2/Vodafone-only enterprise site on legacy 2G at 2000m²: CG2000 at £935.00, Band 20+8, accept EE/Three data-only at class output.

Quick verdict: the CW2000 and CW1000 speak the same universal Band 1 language at the same ≥70/75dB gain and with the same included Yagi, with the £250 difference buying 2000m², 200 users, a +7dBm output step for five times the power and ten antenna zones rather than a new network; the CW2000 and CG2000 cost the same and match on scale, so there the Band 1 versus Band 8 call path decides — pick CW2000 for mixed-network 3G at high output with ten zones, CW1000 for commercial single-floor, CG2000 for O2/Vodafone 2G only.
